+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+ as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+ var accept = accepts(req)
+
+ // the order of this list is significant; should be server preferred order
+ switch (accept.type(['json', 'html'])) {
+ case 'json':
+ res.setHeader('Content-Type', 'application/json')
+ res.write('{"hello":"world!"}')
+ break
+ case 'html':
+ res.setHeader('Content-Type', 'text/html')
+ res.write('hello, world!')
+ break
+ default:
+ // the fallback is text/plain, so no need to specify it above
+ res.setHeader('Content-Type', 'text/plain')
+ res.write('hello, world!')
+ break
+ }
+
+ res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+
+### Bug fixes
+
+Fix exponential behavior (manifesting itself as a complete hang for even relatively small source files) introduced by the new 'use strict' check.

+
+### Bug fixes
+
+Don't ignore period or 'e' characters after octal numbers.
+
+Fix broken parsing for call expressions in default parameter values of arrow functions.
+
+## 4.0.1 (2016-08-08)
+
+### Bug fixes
+
+Fix false positives in duplicated export name errors.
+
+## 4.0.0 (2016-08-07)
+
+### Breaking changes
+
+The default `ecmaVersion` option value is now 7.
+
+A number of internal method signatures changed, so plugins might need to be updated.
+
+### Bug fixes
+
+The parser now raises errors on duplicated export names.
+
+`arguments` and `eval` can now be used in shorthand properties.
+
+Duplicate parameter names in non-simple argument lists now always produce an error.
+

+Support for `async`/`await` syntax when `ecmaVersion` is >= 8.
+
+Support for trailing commas in call expressions when `ecmaVersion` is >= 8.
+
+## 3.3.0 (2016-07-25)
+
+### Bug fixes
+
+Fix bug in tokenizing of regexp operator after a function declaration.
+
+Fix parser crash when parsing an array pattern with a hole.

+Visitors created with `visit.make` now have their base as _prototype_, rather than copying properties into a fresh object.
+
+## 3.1.0 (2016-04-18)
+
+### Bug fixes
+
+Properly tokenize the division operator directly after a function expression.
+
+Allow trailing comma in destructuring arrays.
+
+## 3.0.4 (2016-02-25)
+
+### Fixes
+
+Allow update expressions as left-hand-side of the ES7 exponential operator.
+
+## 3.0.2 (2016-02-10)
+
+### Fixes
+
+Fix bug that accidentally made `undefined` a reserved word when parsing ES7.
+
+## 3.0.0 (2016-02-10)
+
+### Breaking changes
+
+The default value of the `ecmaVersion` option is now 6 (used to be 5).
+
+Support for comprehension syntax (which was dropped from the draft spec) has been removed.
+
+### Fixes
+
+`let` and `yield` are now “contextual keywords”, meaning you can mostly use them as identifiers in ES5 non-strict code.
+
+A parenthesized class or function expression after `export default` is now parsed correctly.
+
+### New features
+
+When `ecmaVersion` is set to 7, Acorn will parse the exponentiation operator (`**`).
+
+The identifier character ranges are now based on Unicode 8.0.0.
+
+Plugins can now override the `raiseRecoverable` method to override the way non-critical errors are handled.
+
+## 2.7.0 (2016-01-04)
+
+### Fixes
+
+Stop allowing rest parameters in setters.
+
+Disallow `y` rexexp flag in ES5.
+
+Disallow `\00` and `\000` escapes in strict mode.
+
+Raise an error when an import name is a reserved word.
+
+## 2.6.2 (2015-11-10)
+
+### Fixes
+
+Don't crash when no options object is passed.
+
+## 2.6.0 (2015-11-09)
+
+### Fixes
+
+Add `await` as a reserved word in module sources.
+
+Disallow `yield` in a parameter default value for a generator.
+
+Forbid using a comma after a rest pattern in an array destructuring.
+
+### New features
+
+Support parsing stdin in command-line tool.
+
+## 2.5.0 (2015-10-27)
+
+### Fixes
+
+Fix tokenizer support in the command-line tool.
+
+Stop allowing `new.target` outside of functions.
+
+Remove legacy `guard` and `guardedHandler` properties from try nodes.
+
+Stop allowing multiple `__proto__` properties on an object literal in strict mode.
+
+Don't allow rest parameters to be non-identifier patterns.
+
+Check for duplicate paramter names in arrow functions.

+# Acorn
+
+A tiny, fast JavaScript parser written in JavaScript.
+
+## Community
+
+Acorn is open source software released under an
+[MIT license](https://github.com/acornjs/acorn/blob/master/acorn/LICENSE).
+
+You are welcome to
+[report bugs](https://github.com/acornjs/acorn/issues) or create pull
+requests on [github](https://github.com/acornjs/acorn). For questions
+and discussion, please use the
+[Tern discussion forum](https://discuss.ternjs.net).
+
+## Installation
+
+The easiest way to install acorn is from [`npm`](https://www.npmjs.com/):
+
+```sh
+npm install acorn
+```
+
+Alternately, you can download the source and build acorn yourself:
+
+```sh
+git clone https://github.com/acornjs/acorn.git
+cd acorn
+npm install
+```
+
+## Interface
+
+**parse**`(input, options)` is the main interface to the library. The
+`input` parameter is a string, `options` can be undefined or an object
+setting some of the options listed below. The return value will be an
+abstract syntax tree object as specified by the [ESTree
+spec](https://github.com/estree/estree).
+
+```javascript
+let acorn = require("acorn");
+console.log(acorn.parse("1 + 1"));
+```
+
+When encountering a syntax error, the parser will raise a
+`SyntaxError` object with a meaningful message. The error object will
+have a `pos` property that indicates the string offset at which the
+error occurred, and a `loc` object that contains a `{line, column}`
+object referring to that same position.
+
+Options can be provided by passing a second argument, which should be
+an object containing any of these fields:
+
+- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
+ either 3, 5, 6 (2015), 7 (2016), 8 (2017), 9 (2018), 10 (2019) or 11
+ (2020, partial support). This influences support for strict mode,
+ the set of reserved words, and support for new syntax features.
+ Default is 10.
+
+ **NOTE**: Only 'stage 4' (finalized) ECMAScript features are being
+ implemented by Acorn. Other proposed new features can be implemented
+ through plugins.
+
+- **sourceType**: Indicate the mode the code should be parsed in. Can be
+ either `"script"` or `"module"`. This influences global strict mode
+ and parsing of `import` and `export` declarations.
+
+ **NOTE**: If set to `"module"`, then static `import` / `export` syntax
+ will be valid, even if `ecmaVersion` is less than 6.
+
+- **onInsertedSemicolon**: If given a callback, that callback will be
+ called whenever a missing semicolon is inserted by the parser. The
+ callback will be given the character offset of the point where the
+ semicolon is inserted as argument, and if `locations` is on, also a
+ `{line, column}` object representing this position.
+
+- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing
+ commas.
+
+- **allowReserved**: If `false`, using a reserved word will generate
+ an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher
+ versions. When given the value `"never"`, reserved words and
+ keywords can also not be used as property names (as in Internet
+ Explorer's old parser).
+
+- **allowReturnOutsideFunction**: By default, a return statement at
+ the top level raises an error. Set this to `true` to accept such
+ code.
+
+- **allowImportExportEverywhere**: By default, `import` and `export`
+ declarations can only appear at a program's top level. Setting this
+ option to `true` allows them anywhere where a statement is allowed.
+
+- **allowAwaitOutsideFunction**: By default, `await` expressions can
+ only appear inside `async` functions. Setting this option to
+ `true` allows to have top-level `await` expressions. They are
+ still not allowed in non-`async` functions, though.
+
+- **allowHashBang**: When this is enabled (off by default), if the
+ code starts with the characters `#!` (as in a shellscript), the
+ first line will be treated as a comment.
+
+- **locations**: When `true`, each node has a `loc` object attached
+ with `start` and `end` subobjects, each of which contains the
+ one-based line and zero-based column numbers in `{line, column}`
+ form. Default is `false`.
+
+- **onToken**: If a function is passed for this option, each found
+ token will be passed in same format as tokens returned from
+ `tokenizer().getToken()`.
+
+ If array is passed, each found token is pushed to it.
+
+ Note that you are not allowed to call the parser from the
+ callback—that will corrupt its internal state.
+
+- **onComment**: If a function is passed for this option, whenever a
+ comment is encountered the function will be called with the
+ following parameters:
+
+ - `block`: `true` if the comment is a block comment, false if it
+ is a line comment.
+ - `text`: The content of the comment.
+ - `start`: Character offset of the start of the comment.
+ - `end`: Character offset of the end of the comment.
+
+ When the `locations` options is on, the `{line, column}` locations
+ of the comment’s start and end are passed as two additional
+ parameters.
+
+ If array is passed for this option, each found comment is pushed
+ to it as object in Esprima format:
+
+ ```javascript
+ {
+ "type": "Line" | "Block",
+ "value": "comment text",
+ "start": Number,
+ "end": Number,
+ // If `locations` option is on:
+ "loc": {
+ "start": {line: Number, column: Number}
+ "end": {line: Number, column: Number}
+ },
+ // If `ranges` option is on:
+ "range": [Number, Number]
+ }
+ ```
+
+ Note that you are not allowed to call the parser from the
+ callback—that will corrupt its internal state.
+
+- **ranges**: Nodes have their start and end characters offsets
+ recorded in `start` and `end` properties (directly on the node,
+ rather than the `loc` object, which holds line/column data. To also
+ add a
+ [semi-standardized](https://bugzilla.mozilla.org/show_bug.cgi?id=745678)
+ `range` property holding a `[start, end]` array with the same
+ numbers, set the `ranges` option to `true`.
+
+- **program**: It is possible to parse multiple files into a single
+ AST by passing the tree produced by parsing the first file as the
+ `program` option in subsequent parses. This will add the toplevel
+ forms of the parsed file to the "Program" (top) node of an existing
+ parse tree.
+
+- **sourceFile**: When the `locations` option is `true`, you can pass
+ this option to add a `source` attribute in every node’s `loc`
+ object. Note that the contents of this option are not examined or
+ processed in any way; you are free to use whatever format you
+ choose.
+
+- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property
+ will be added (regardless of the `location` option) directly to the
+ nodes, rather than the `loc` object.
+
+- **preserveParens**: If this option is `true`, parenthesized expressions
+ are represented by (non-standard) `ParenthesizedExpression` nodes
+ that have a single `expression` property containing the expression
+ inside parentheses.
+
+**parseExpressionAt**`(input, offset, options)` will parse a single
+expression in a string, and return its AST. It will not complain if
+there is more of the string left after the expression.
+
+**tokenizer**`(input, options)` returns an object with a `getToken`
+method that can be called repeatedly to get the next token, a `{start,
+end, type, value}` object (with added `loc` property when the
+`locations` option is enabled and `range` property when the `ranges`
+option is enabled). When the token's type is `tokTypes.eof`, you
+should stop calling the method, since it will keep returning that same
+token forever.
+
+In ES6 environment, returned result can be used as any other
+protocol-compliant iterable:
+
+```javascript
+for (let token of acorn.tokenizer(str)) {
+ // iterate over the tokens
+}
+
+// transform code to array of tokens:
+var tokens = [...acorn.tokenizer(str)];
+```
+
+**tokTypes** holds an object mapping names to the token type objects
+that end up in the `type` properties of tokens.
+
+**getLineInfo**`(input, offset)` can be used to get a `{line,
+column}` object for a given program string and offset.
+
+### The `Parser` class
+
+Instances of the **`Parser`** class contain all the state and logic
+that drives a parse. It has static methods `parse`,
+`parseExpressionAt`, and `tokenizer` that match the top-level
+functions by the same name.
+
+When extending the parser with plugins, you need to call these methods
+on the extended version of the class. To extend a parser with plugins,
+you can use its static `extend` method.
+
+```javascript
+var acorn = require("acorn");
+var jsx = require("acorn-jsx");
+var JSXParser = acorn.Parser.extend(jsx());
+JSXParser.parse("foo()");
+```
+
+The `extend` method takes any number of plugin values, and returns a
+new `Parser` class that includes the extra parser logic provided by
+the plugins.
+
+## Command line interface
+
+The `bin/acorn` utility can be used to parse a file from the command
+line. It accepts as arguments its input file and the following
+options:
+
+- `--ecma3|--ecma5|--ecma6|--ecma7|--ecma8|--ecma9|--ecma10`: Sets the ECMAScript version
+ to parse. Default is version 9.
+
+- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise.
+
+- `--locations`: Attaches a "loc" object to each node with "start" and
+ "end" subobjects, each of which contains the one-based line and
+ zero-based column numbers in `{line, column}` form.
+
+- `--allow-hash-bang`: If the code starts with the characters #! (as
+ in a shellscript), the first line will be treated as a comment.
+
+- `--compact`: No whitespace is used in the AST output.
+
+- `--silent`: Do not output the AST, just return the exit status.
+
+- `--help`: Print the usage information and quit.
+
+The utility spits out the syntax tree as JSON data.

+AsyncKit provides harness for `parallel` and `serial` iterators over list of items represented by arrays or objects.
+Optionally it accepts abort function (should be synchronously return by iterator for each item), and terminates left over jobs upon an error event. For specific iteration order built-in (`ascending` and `descending`) and custom sort helpers also supported, via `asynckit.serialOrdered` method.
+
+It ensures async operations to keep behavior more stable and prevent `Maximum call stack size exceeded` errors, from sync iterators.

+
+## Install
+
+```sh
+$ npm install --save asynckit
+```
+
+## Examples
+
+### Parallel Jobs
+
+Runs iterator over provided array in parallel. Stores output in the `result` array,
+on the matching positions. In unlikely event of an error from one of the jobs,
+will terminate rest of the active jobs (if abort function is provided)
+and return error along with salvaged data to the main callback function.
+
+#### Input Array
+
+```javascript
+var parallel = require('asynckit').parallel
+ , assert = require('assert')
+ ;
+
+var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+ , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+ , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
+ , target = []
+ ;
+
+parallel(source, asyncJob, function(err, result)
+{
+ assert.deepEqual(result, expectedResult);
+ assert.deepEqual(target, expectedTarget);
+});
+
+// async job accepts one element from the array
+// and a callback function
+function asyncJob(item, cb)
+{
+ // different delays (in ms) per item
+ var delay = item * 25;
+
+ // pretend different jobs take different time to finish
+ // and not in consequential order
+ var timeoutId = setTimeout(function() {
+ target.push(item);
+ cb(null, item * 2);
+ }, delay);
+
+ // allow to cancel "leftover" jobs upon error
+ // return function, invoking of which will abort this job
+ return clearTimeout.bind(null, timeoutId);
+}
+```
+
+More examples could be found in [test/test-parallel-array.js](test/test-parallel-array.js).
+
+#### Input Object
+
+Also it supports named jobs, listed via object.
+
+```javascript
+var parallel = require('asynckit/parallel')
+ , assert = require('assert')
+ ;
+
+var source = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
+ , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
+ , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
+ , expectedKeys = [ 'first', 'one', 'two', 'four', 'eight', 'sixteen', 'thirtyTwo', 'sixtyFour' ]
+ , target = []
+ , keys = []
+ ;
+
+parallel(source, asyncJob, function(err, result)
+{
+ assert.deepEqual(result, expectedResult);
+ assert.deepEqual(target, expectedTarget);
+ assert.deepEqual(keys, expectedKeys);
+});
+
+// supports full value, key, callback (shortcut) interface
+function asyncJob(item, key, cb)
+{
+ // different delays (in ms) per item
+ var delay = item * 25;
+
+ // pretend different jobs take different time to finish
+ // and not in consequential order
+ var timeoutId = setTimeout(function() {
+ keys.push(key);
+ target.push(item);
+ cb(null, item * 2);
+ }, delay);
+
+ // allow to cancel "leftover" jobs upon error
+ // return function, invoking of which will abort this job
+ return clearTimeout.bind(null, timeoutId);
+}
+```
+
+More examples could be found in [test/test-parallel-object.js](test/test-parallel-object.js).
+
+### Serial Jobs
+
+Runs iterator over provided array sequentially. Stores output in the `result` array,
+on the matching positions. In unlikely event of an error from one of the jobs,
+will not proceed to the rest of the items in the list
+and return error along with salvaged data to the main callback function.
+
+#### Input Array
+
+```javascript
+var serial = require('asynckit/serial')
+ , assert = require('assert')
+ ;
+
+var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+ , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+ , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
+ , target = []
+ ;
+
+serial(source, asyncJob, function(err, result)
+{
+ assert.deepEqual(result, expectedResult);
+ assert.deepEqual(target, expectedTarget);
+});
+
+// extended interface (item, key, callback)
+// also supported for arrays
+function asyncJob(item, key, cb)
+{
+ target.push(key);
+
+ // it will be automatically made async
+ // even it iterator "returns" in the same event loop
+ cb(null, item * 2);
+}
+```
+
+More examples could be found in [test/test-serial-array.js](test/test-serial-array.js).
+
+#### Input Object
+
+Also it supports named jobs, listed via object.
+
+```javascript
+var serial = require('asynckit').serial
+ , assert = require('assert')
+ ;
+
+var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+ , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+ , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
+ , target = []
+ ;
+
+var source = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
+ , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
+ , expectedTarget = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+ , target = []
+ ;
+
+
+serial(source, asyncJob, function(err, result)
+{
+ assert.deepEqual(result, expectedResult);
+ assert.deepEqual(target, expectedTarget);
+});
+
+// shortcut interface (item, callback)
+// works for object as well as for the arrays
+function asyncJob(item, cb)
+{
+ target.push(item);
+
+ // it will be automatically made async
+ // even it iterator "returns" in the same event loop
+ cb(null, item * 2);
+}
+```
+
+More examples could be found in [test/test-serial-object.js](test/test-serial-object.js).
+
+_Note: Since _object_ is an _unordered_ collection of properties,
+it may produce unexpected results with sequential iterations.
+Whenever order of the jobs' execution is important please use `serialOrdered` method._
+
+### Ordered Serial Iterations
+
+TBD
+
+For example [compare-property](compare-property) package.

+# babel-walk
+
+Lightweight AST traversal tools for [Babel] ASTs.
+
+[Babel] supplies the wonderful [babel-traverse] module for walking Babel ASTs. Problem is, babel-traverse is very heavyweight, as it is designed to supply utilities to make all sorts of AST transformations possible. For simple AST walking without transformation, babel-traverse brings a lot of overhead.
+
+This module loosely implements the API of Acorn parser's [walk module], which is a lightweight AST walker for the ESTree AST format.
+
+In my tests, babel-walk's ancestor walker (the most complex walker provided by this module) is about 8 times faster than babel-traverse, if the visitors are cached and the same AST is used for all runs. It is about 16 times faster if a fresh AST is used every run.

+[walk module]: https://github.com/ternjs/acorn#distwalkjs
+
+## Installation
+
+```sh
+$ npm install babel-walk
+```
+
+## API
+
+```js
+var walk = require('babel-walk');
+```
+
+### walk.simple(visitors)(node, state)
+
+Do a simple walk over the AST. `node` should be the AST node to walk, and `visitors` an object containing Babel [visitors]. Each visitor function will be called as `(node, state)`, where `node` is the AST node, and `state` is the same `state` passed to `walk.simple`.
+
+When `walk.simple` is called with a fresh set of visitors, it will first "explode" the visitors (e.g. expanding `Visitor(node, state) {}` to `Visitor() { enter(node, state) {} }`). This exploding process can take some time, so it is recommended to cache the result of calling `walk.simple(visitors)` and communicate state leveraging the `state` parameter.
+
+All [babel-types] aliases (e.g. `Expression`) work, but the union syntax (e.g. `'Identifier|AssignmentPattern'(node, state) {}`) does not.
+
+### walk.ancestor(visitors)(node, state)
+
+Do a simple walk over the AST, but memoizing the ancestors of the node and making them available to the visitors. `node` should be the AST node to walk, and `visitors` an object containing Babel [visitors]. Each visitor function will be called as `(node, state, ancestors)`, where `node` is the AST node, `state` is the same `state` passed to `walk.ancestor`, and `ancestors` is an array of ancestors to the node (with the outermost node being `[0]` and the current node being `[ancestors.length - 1]`). If `state` is not specified in the call to `walk.ancestor`, the `state` parameter will be set to `ancestors`.
+
+When `walk.ancestor` is called with a fresh set of visitors, it will first "explode" the visitors (e.g. expanding `Visitor(node, state) {}` to `Visitor() { enter(node, state) {} }`). This exploding process can take some time, so it is recommended to cache the result of calling `walk.ancestor(visitors)` and communicate state leveraging the `state` parameter.
+
+All [babel-types] aliases (e.g. `Expression`) work, but the union syntax (e.g. `'Identifier|AssignmentPattern'(node, state) {}`) does not.
+
+### walk.recursive(visitors)(node, state)
+
+Do a recursive walk over the AST, where the visitors are responsible for continuing the walk on the child nodes of their target node. `node` should be the AST node to walk, and `visitors` an object containing Babel [visitors]. Each visitor function will be called as `(node, state, c)`, where `node` is the AST node, `state` is the same `state` passed to `walk.recursive`, and `c` is a function that takes a single node as argument and continues walking _that_ node. If no visitor for a node is provided, the default walker algorithm will still be used.
+
+When `walk.recursive` is called with a fresh set of visitors, it will first "explode" the visitors (e.g. expanding `Visitor(node, state) {}` to `Visitor() { enter(node, state) {} }`). This exploding process can take some time, so it is recommended to cache the result of calling `walk.recursive(visitors)` and communicate state leveraging the `state` parameter.
+
+Unlike other babel-walk walkers, `walk.recursive` does not call the `exit` visitor, only the `enter` (the default) visitor, of a specific node type.
+
+All [babel-types] aliases (e.g. `Expression`) work, but the union syntax (e.g. `'Identifier|AssignmentPattern'(node, state) {}`) does not.
+
+In the following example, we are trying to count the number of functions in the outermost scope. This means, that we can simply walk all the statements and increment a counter if it is a function declaration or expression, and then stop walking. Note that we do not specify a visitor for the `Program` node, and the default algorithm for walking `Program` nodes is used (which is what we want). Also of note is how I bring the `visitors` object outside of `countFunctions` so that the object can be cached to improve performance.
+
+```js
+import * as t from 'babel-types';
+import {parse} from 'babel';
+import * as walk from 'babel-walk';
+
+const visitors = walk.recursive({
+ Statement(node, state, c) {
+ if (t.isVariableDeclaration(node)) {
+ for (let declarator of node.declarations) {
+ // Continue walking the declarator
+ c(declarator);
+ }
+ } else if (t.isFunctionDeclaration(node)) {
+ state.counter++;
+ }
+ },
+
+ VariableDeclarator(node, state) {
+ if (t.isFunction(node.init)) {
+ state.counter++;
+ }
+ },
+});
+
+function countFunctions(node) {
+ const state = {
+ counter: 0,
+ };
+ visitors(node, state);
+ return state.counter;
+}
+
+const ast = parse(`
+ // Counts
+ var a = () => {};
+
+ // Counts
+ function b() {
+ // Doesn't count
+ function c() {
+ }
+ }
+
+ // Counts
+ const c = function d() {};
+`);
+
+countFunctions(ast);
+// = 3
+```

+
+## Caveat
+
+For those of you migrating from Acorn to Babel, there are a few things to be aware of.
+
+1. The visitor caching suggestions do not apply to Acorn's walk module, but do for babel-walk.
+
+2. babel-walk does not provide any of the other functions Acorn's walk module provides (e.g. `make`, `findNode*`).
+
+3. babel-walk does not use a `base` variable. The walker algorithm is the same as what babel-traverse uses.
+ - That means certain nodes that are not walked by Acorn, such as the `property` property of a non-computed `MemberExpression`, are walked by babel-walk.

+# balanced-match
+
+Match balanced string pairs, like `{` and `}` or `` and ``. Supports regular expressions as well!
+
+[](http://travis-ci.org/juliangruber/balanced-match)
+[](https://www.npmjs.org/package/balanced-match)
+
+[](https://ci.testling.com/juliangruber/balanced-match)
+
+## Example
+
+Get the first matching pair of braces:
+
+```js
+var balanced = require('balanced-match');
+
+console.log(balanced('{', '}', 'pre{in{nested}}post'));
+console.log(balanced('{', '}', 'pre{first}between{second}post'));
+console.log(balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre { in{nest} } post'));
+```
+
+The matches are:
+
+```bash
+$ node example.js
+{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
+{ start: 3,
+ end: 9,
+ pre: 'pre',
+ body: 'first',
+ post: 'between{second}post' }
+{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
+```
+
+## API
+
+### var m = balanced(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+object with those keys:
+
+* **start** the index of the first match of `a`
+* **end** the index of the matching `b`
+* **pre** the preamble, `a` and `b` not included
+* **body** the match, `a` and `b` not included
+* **post** the postscript, `a` and `b` not included
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
+
+### var r = balanced.range(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+array with indexes: `[ , ]`.
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.
+
+## Installation
+
+With [npm](https://npmjs.org) do:
+
+```bash
+npm install balanced-match
+```
+

+Node.js body parsing middleware.
+
+Parse incoming request bodies in a middleware before your handlers, available
+under the `req.body` property.
+
+**Note** As `req.body`'s shape is based on user-controlled input, all
+properties and values in this object are untrusted and should be validated
+before trusting. For example, `req.body.foo.toString()` may fail in multiple
+ways, for example the `foo` property may not be there or may not be a string,
+and `toString` may not be a function and instead a string or other user input.
+
+[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/).
+
+_This does not handle multipart bodies_, due to their complex and typically
+large nature. For multipart bodies, you may be interested in the following
+modules:
+
+ * [busboy](https://www.npmjs.org/package/busboy#readme) and
+ [connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
+ * [multiparty](https://www.npmjs.org/package/multiparty#readme) and
+ [connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
+ * [formidable](https://www.npmjs.org/package/formidable#readme)
+ * [multer](https://www.npmjs.org/package/multer#readme)
+
+This module provides the following parsers:
+
+ * [JSON body parser](#bodyparserjsonoptions)
+ * [Raw body parser](#bodyparserrawoptions)
+ * [Text body parser](#bodyparsertextoptions)
+ * [URL-encoded form body parser](#bodyparserurlencodedoptions)
+
+Other body parsers you might be interested in:
+
+- [body](https://www.npmjs.org/package/body#readme)
+- [co-body](https://www.npmjs.org/package/co-body#readme)
+
+## Installation
+
+```sh
+$ npm install body-parser
+```
+
+## API
+
+```js
+var bodyParser = require('body-parser')
+```
+
+The `bodyParser` object exposes various factories to create middlewares. All
+middlewares will populate the `req.body` property with the parsed body when
+the `Content-Type` request header matches the `type` option, or an empty
+object (`{}`) if there was no body to parse, the `Content-Type` was not matched,
+or an error occurred.
+
+The various errors returned by this module are described in the
+[errors section](#errors).
+
+### bodyParser.json([options])
+
+Returns middleware that only parses `json` and only looks at requests where
+the `Content-Type` header matches the `type` option. This parser accepts any
+Unicode encoding of the body and supports automatic inflation of `gzip` and
+`deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`).
+
+#### Options
+
+The `json` function takes an optional `options` object that may contain any of
+the following keys:
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### reviver
+
+The `reviver` option is passed directly to `JSON.parse` as the second
+argument. You can find more information on this argument
+[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
+
+##### strict
+
+When set to `true`, will only accept arrays and objects; when `false` will
+accept anything `JSON.parse` accepts. Defaults to `true`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a string, array of strings, or a function. If not a
+function, `type` option is passed directly to the
+[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
+be an extension name (like `json`), a mime type (like `application/json`), or
+a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type`
+option is called as `fn(req)` and the request is parsed if it returns a truthy
+value. Defaults to `application/json`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.raw([options])
+
+Returns middleware that parses all bodies as a `Buffer` and only looks at
+requests where the `Content-Type` header matches the `type` option. This
+parser supports automatic inflation of `gzip` and `deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This will be a `Buffer` object
+of the body.
+
+#### Options
+
+The `raw` function takes an optional `options` object that may contain any of
+the following keys:
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a string, array of strings, or a function.
+If not a function, `type` option is passed directly to the
+[type-is](https://www.npmjs.org/package/type-is#readme) library and this
+can be an extension name (like `bin`), a mime type (like
+`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
+`application/*`). If a function, the `type` option is called as `fn(req)`
+and the request is parsed if it returns a truthy value. Defaults to
+`application/octet-stream`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.text([options])
+
+Returns middleware that parses all bodies as a string and only looks at
+requests where the `Content-Type` header matches the `type` option. This
+parser supports automatic inflation of `gzip` and `deflate` encodings.
+
+A new `body` string containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This will be a string of the
+body.
+
+#### Options
+
+The `text` function takes an optional `options` object that may contain any of
+the following keys:
+
+##### defaultCharset
+
+Specify the default character set for the text content if the charset is not
+specified in the `Content-Type` header of the request. Defaults to `utf-8`.
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a string, array of strings, or a function. If not
+a function, `type` option is passed directly to the
+[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
+be an extension name (like `txt`), a mime type (like `text/plain`), or a mime
+type with a wildcard (like `*/*` or `text/*`). If a function, the `type`
+option is called as `fn(req)` and the request is parsed if it returns a
+truthy value. Defaults to `text/plain`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.urlencoded([options])
+
+Returns middleware that only parses `urlencoded` bodies and only looks at
+requests where the `Content-Type` header matches the `type` option. This
+parser accepts only UTF-8 encoding of the body and supports automatic
+inflation of `gzip` and `deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This object will contain
+key-value pairs, where the value can be a string or array (when `extended` is
+`false`), or any type (when `extended` is `true`).
+
+#### Options
+
+The `urlencoded` function takes an optional `options` object that may contain
+any of the following keys:
+
+##### extended
+
+The `extended` option allows to choose between parsing the URL-encoded data
+with the `querystring` library (when `false`) or the `qs` library (when
+`true`). The "extended" syntax allows for rich objects and arrays to be
+encoded into the URL-encoded format, allowing for a JSON-like experience
+with URL-encoded. For more information, please
+[see the qs library](https://www.npmjs.org/package/qs#readme).
+
+Defaults to `true`, but using the default has been deprecated. Please
+research into the difference between `qs` and `querystring` and choose the
+appropriate setting.
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### parameterLimit
+
+The `parameterLimit` option controls the maximum number of parameters that
+are allowed in the URL-encoded data. If a request contains more parameters
+than this value, a 413 will be returned to the client. Defaults to `1000`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a string, array of strings, or a function. If not
+a function, `type` option is passed directly to the
+[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
+be an extension name (like `urlencoded`), a mime type (like
+`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
+`*/x-www-form-urlencoded`). If a function, the `type` option is called as
+`fn(req)` and the request is parsed if it returns a truthy value. Defaults
+to `application/x-www-form-urlencoded`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+## Errors
+
+The middlewares provided by this module create errors using the
+[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors
+will typically have a `status`/`statusCode` property that contains the suggested
+HTTP response code, an `expose` property to determine if the `message` property
+should be displayed to the client, a `type` property to determine the type of
+error without matching against the `message`, and a `body` property containing
+the read body, if available.
+
+The following are the common errors created, though any error can come through
+for various reasons.
+
+### content encoding unsupported
+
+This error will occur when the request had a `Content-Encoding` header that
+contained an encoding but the "inflation" option was set to `false`. The
+`status` property is set to `415`, the `type` property is set to
+`'encoding.unsupported'`, and the `charset` property will be set to the
+encoding that is unsupported.
+
+### entity parse failed
+
+This error will occur when the request contained an entity that could not be
+parsed by the middleware. The `status` property is set to `400`, the `type`
+property is set to `'entity.parse.failed'`, and the `body` property is set to
+the entity value that failed parsing.
+
+### entity verify failed
+
+This error will occur when the request contained an entity that could not be
+failed verification by the defined `verify` option. The `status` property is
+set to `403`, the `type` property is set to `'entity.verify.failed'`, and the
+`body` property is set to the entity value that failed verification.
+
+### request aborted
+
+This error will occur when the request is aborted by the client before reading
+the body has finished. The `received` property will be set to the number of
+bytes received before the request was aborted and the `expected` property is
+set to the number of expected bytes. The `status` property is set to `400`
+and `type` property is set to `'request.aborted'`.
+
+### request entity too large
+
+This error will occur when the request body's size is larger than the "limit"
+option. The `limit` property will be set to the byte limit and the `length`
+property will be set to the request body's length. The `status` property is
+set to `413` and the `type` property is set to `'entity.too.large'`.
+
+### request size did not match content length
+
+This error will occur when the request's length did not match the length from
+the `Content-Length` header. This typically occurs when the request is malformed,
+typically when the `Content-Length` header was calculated based on characters
+instead of bytes. The `status` property is set to `400` and the `type` property
+is set to `'request.size.invalid'`.
+
+### stream encoding should not be set
+
+This error will occur when something called the `req.setEncoding` method prior
+to this middleware. This module operates directly on bytes only and you cannot
+call `req.setEncoding` when using this module. The `status` property is set to
+`500` and the `type` property is set to `'stream.encoding.set'`.
+
+### too many parameters
+
+This error will occur when the content of the request exceeds the configured
+`parameterLimit` for the `urlencoded` parser. The `status` property is set to
+`413` and the `type` property is set to `'parameters.too.many'`.
+
+### unsupported charset "BOGUS"
+
+This error will occur when the request had a charset parameter in the
+`Content-Type` header, but the `iconv-lite` module does not support it OR the
+parser does not support it. The charset is contained in the message as well
+as in the `charset` property. The `status` property is set to `415`, the
+`type` property is set to `'charset.unsupported'`, and the `charset` property
+is set to the charset that is unsupported.
+
+### unsupported content encoding "bogus"
+
+This error will occur when the request had a `Content-Encoding` header that
+contained an unsupported encoding. The encoding is contained in the message
+as well as in the `encoding` property. The `status` property is set to `415`,
+the `type` property is set to `'encoding.unsupported'`, and the `encoding`
+property is set to the encoding that is unsupported.
+
+## Examples
+
+### Express/Connect top-level generic
+
+This example demonstrates adding a generic JSON and URL-encoded parser as a
+top-level middleware, which will parse the bodies of all incoming requests.
+This is the simplest setup.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// parse application/x-www-form-urlencoded
+app.use(bodyParser.urlencoded({ extended: false }))
+
+// parse application/json
+app.use(bodyParser.json())
+
+app.use(function (req, res) {
+ res.setHeader('Content-Type', 'text/plain')
+ res.write('you posted:\n')
+ res.end(JSON.stringify(req.body, null, 2))
+})
+```
+
+### Express route-specific
+
+This example demonstrates adding body parsers specifically to the routes that
+need them. In general, this is the most recommended way to use body-parser with
+Express.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// create application/json parser
+var jsonParser = bodyParser.json()
+
+// create application/x-www-form-urlencoded parser
+var urlencodedParser = bodyParser.urlencoded({ extended: false })
+
+// POST /login gets urlencoded bodies
+app.post('/login', urlencodedParser, function (req, res) {
+ res.send('welcome, ' + req.body.username)
+})
+
+// POST /api/users gets JSON bodies
+app.post('/api/users', jsonParser, function (req, res) {
+ // create user in req.body
+})
+```
+
+### Change accepted type for parsers
+
+All the parsers accept a `type` option which allows you to change the
+`Content-Type` that the middleware will parse.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// parse various different custom JSON types as JSON
+app.use(bodyParser.json({ type: 'application/*+json' }))
+
+// parse some custom thing into a Buffer
+app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
+
+// parse an HTML body into a string
+app.use(bodyParser.text({ type: 'text/html' }))
+```

+
+[Brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html),
+as known from sh/bash, in JavaScript.
+
+[](http://travis-ci.org/juliangruber/brace-expansion)
+[](https://www.npmjs.org/package/brace-expansion)
+[](https://greenkeeper.io/)
+
+[](https://ci.testling.com/juliangruber/brace-expansion)
+
+## Example
+
+```js
+var expand = require('brace-expansion');
+
+expand('file-{a,b,c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('-v{,,}')
+// => ['-v', '-v', '-v']
+
+expand('file{0..2}.jpg')
+// => ['file0.jpg', 'file1.jpg', 'file2.jpg']
+
+expand('file-{a..c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('file{2..0}.jpg')
+// => ['file2.jpg', 'file1.jpg', 'file0.jpg']
+
+expand('file{0..4..2}.jpg')
+// => ['file0.jpg', 'file2.jpg', 'file4.jpg']
+
+expand('file-{a..e..2}.jpg')
+// => ['file-a.jpg', 'file-c.jpg', 'file-e.jpg']
+
+expand('file{00..10..5}.jpg')
+// => ['file00.jpg', 'file05.jpg', 'file10.jpg']
+
+expand('{{A..C},{a..c}}')
+// => ['A', 'B', 'C', 'a', 'b', 'c']
+
+expand('ppp{,config,oe{,conf}}')
+// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
+```
+
+## API
+
+```js
+var expand = require('brace-expansion');
+```
+
+### var expanded = expand(str)
+
+Return an array of all possible and valid expansions of `str`. If none are
+found, `[str]` is returned.
+
+Valid expansions are:
+
+```js
+/^(.*,)+(.+)?$/
+// {a,b,...}
+```
+
+A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+A numeric sequence from `x` to `y` inclusive, with optional increment.
+If `x` or `y` start with a leading `0`, all the numbers will be padded
+to have equal length. Negative numbers and backwards iteration work too.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+An alphabetic sequence from `x` to `y` inclusive, with optional increment.
+`x` and `y` must be exactly one character, and if given, `incr` must be a
+number.
+
+For compatibility reasons, the string `${` is not eligible for brace expansion.
+
+## Installation
+
+With [npm](https://npmjs.org) do:

+# Bytes utility
+
+[![NPM Version][npm-image]][npm-url]
+[![NPM Downloads][downloads-image]][downloads-url]
+[![Build Status][ci-image]][ci-url]
+[![Test Coverage][coveralls-image]][coveralls-url]
+
+Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```bash
+$ npm install bytes
+```
+
+## Usage
+
+```js
+var bytes = require('bytes');
+```
+
+#### bytes(number｜string value, [options]): number｜string｜null
+
+Default export function. Delegates to either `bytes.format` or `bytes.parse` based on the type of `value`.
+
+**Arguments**
+
+| Name | Type | Description |
+|---------|----------|--------------------|
+| value | `number`｜`string` | Number value to format or string value to parse |
+| options | `Object` | Conversion options for `format` |
+
+**Returns**
+
+| Name | Type | Description |
+|---------|------------------|-------------------------------------------------|
+| results | `string`｜`number`｜`null` | Return null upon error. Numeric value in bytes, or string value otherwise. |
+
+**Example**
+
+```js
+bytes(1024);
+// output: '1KB'
+
+bytes('1KB');
+// output: 1024
+```
+
+#### bytes.format(number value, [options]): string｜null
+
+Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
+ rounded.
+
+**Arguments**
+
+| Name | Type | Description |
+|---------|----------|--------------------|
+| value | `number` | Value in bytes |
+| options | `Object` | Conversion options |
+
+**Options**
+
+| Property | Type | Description |
+|-------------------|--------|-----------------------------------------------------------------------------------------|
+| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. |
+| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` |
+| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `'.'`... Default value to `''`. |
+| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
+| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. |
+
+**Returns**
+
+| Name | Type | Description |
+|---------|------------------|-------------------------------------------------|
+| results | `string`｜`null` | Return null upon error. String value otherwise. |
+
+**Example**
+
+```js
+bytes.format(1024);
+// output: '1KB'
+
+bytes.format(1000);
+// output: '1000B'
+
+bytes.format(1000, {thousandsSeparator: ' '});
+// output: '1 000B'
+
+bytes.format(1024 * 1.7, {decimalPlaces: 0});
+// output: '2KB'
+
+bytes.format(1024, {unitSeparator: ' '});
+// output: '1 KB'
+```
+
+#### bytes.parse(string｜number value): number｜null
+
+Parse the string value into an integer in bytes. If no unit is given, or `value`
+is a number, it is assumed the value is in bytes.
+
+Supported units and abbreviations are as follows and are case-insensitive:
+
+ * `b` for bytes
+ * `kb` for kilobytes
+ * `mb` for megabytes
+ * `gb` for gigabytes
+ * `tb` for terabytes
+ * `pb` for petabytes
+
+The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
+
+**Arguments**
+
+| Name | Type | Description |
+|---------------|--------|--------------------|
+| value | `string`｜`number` | String to parse, or number in bytes. |
+
+**Returns**
+
+| Name | Type | Description |
+|---------|-------------|-------------------------|
+| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. |
+
+**Example**
+
+```js
+bytes.parse('1KB');
+// output: 1024
+
+bytes.parse('1024');
+// output: 1024
+
+bytes.parse(1024);
+// output: 1024

+### [See what's new in Chalk 2](https://github.com/chalk/chalk/releases/tag/v2.0.0)
+
+
+
+
+## Highlights
+
+- Expressive API
+- Highly performant
+- Ability to nest styles
+- [256/Truecolor color support](#256-and-truecolor-color-support)
+- Auto-detects color support
+- Doesn't extend `String.prototype`
+- Clean and focused
+- Actively maintained
+- [Used by ~23,000 packages](https://www.npmjs.com/browse/depended/chalk) as of December 31, 2017
+
+
+## Install
+
+```console
+$ npm install chalk
+```
+
+
+ 
+
+
+
+## Usage
+
+```js
+const chalk = require('chalk');
+
+console.log(chalk.blue('Hello world!'));
+```
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+const chalk = require('chalk');
+const log = console.log;
+
+// Combine styled and normal strings
+log(chalk.blue('Hello') + ' World' + chalk.red('!'));
+
+// Compose multiple styles using the chainable API
+log(chalk.blue.bgRed.bold('Hello world!'));
+
+// Pass in multiple arguments
+log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
+
+// Nest styles
+log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
+
+// Nest styles of the same type even (color, underline, background)
+log(chalk.green(
+ 'I am a green line ' +
+ chalk.blue.underline.bold('with a blue substring') +
+ ' that becomes green again!'
+));
+
+// ES2015 template literal
+log(`
+CPU: ${chalk.red('90%')}
+RAM: ${chalk.green('40%')}
+DISK: ${chalk.yellow('70%')}
+`);
+
+// ES2015 tagged template literal
+log(chalk`
+CPU: {red ${cpu.totalPercent}%}
+RAM: {green ${ram.used / ram.total * 100}%}
+DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
+`);
+
+// Use RGB colors in terminal emulators that support it.
+log(chalk.keyword('orange')('Yay for orange colored text!'));
+log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
+log(chalk.hex('#DEADED').bold('Bold gray!'));
+```
+
+Easily define your own themes:
+
+```js
+const chalk = require('chalk');
+
+const error = chalk.bold.red;
+const warning = chalk.keyword('orange');
+
+console.log(error('Error!'));
+console.log(warning('Warning!'));
+```
+
+Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
+
+```js
+const name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> 'Hello Sindre'
+```
+
