# 0.25.0 (05-10-2018)
- Crystal 0.27.0 support.
- *[breaking change]* Added back `env.params.files`.
Here's a fully working sample for reading a image file upload `image1` and saving it under `public/uploads`.
```crystal
post "/upload" do |env|
file = env.params.files["image1"].tempfile
file_path = ::File.join [Kemal.config.public_folder, "uploads/", File.basename(file.path)]
File.open(file_path, "w") do |f|
IO.copy(file, f)
end
"Upload ok"
end
```
To test
`curl -F "image1=@/Users/serdar/Downloads/kemal.png" http://localhost:3000/upload`
- Cache HTTP routes to increase performance :rocket: [#493](https://github.com/kemalcr/kemal/pull/493)
# 0.24.0 (14-08-2018)
- *[breaking change]* Removed `env.params.files`. You can use Crystal's built-in `HTTP::FormData.parse` instead:
```crystal
post "/upload" do |env|
HTTP::FormData.parse(env.request) do |upload|
filename = file.filename
if !filename.is_a?(String)
"No filename included in upload"
else
file_path = ::File.join [Kemal.config.public_folder, "uploads/", filename]
File.open(file_path, "w") do |f|
IO.copy(file.tmpfile, f)
end
"Upload OK"
end
end
```
- *[breaking change]* From now on to access dynamic url params in a WebSocket route you have to use:
```crystal
ws "/:id" do |socket, context|
id = context.ws_route_lookup.params["id"]
end
```
- *[breaking change]* Removed `_method` magic param.
- Added new exception page [#466](https://github.com/kemalcr/kemal/pull/466). Thanks @mamantoha 🙏
- Support custom port binding. Thanks @straight-shoota 🙏
```crystal
Kemal.run do |config|
server = config.server.not_nil!
server.bind_tcp "127.0.0.1", 3000, reuse_port: true
server.bind_tcp "0.0.0.0", 3001, reuse_port: true
end
```

- Add webm mime type.[#413](https://github.com/kemalcr/kemal/pull/413) thanks @reindeer-cafe 🙏
# 0.21.0 (05-09-2017)
- Dynamically insert handlers :muscle: Fixes [#376](https://github.com/kemalcr/kemal/pull/376).
- Add context to WebSocket. This allows one to use `HTTP::Server::Context` in `ws` declarations :heart_eyes: Fixes [#349](https://github.com/kemalcr/kemal/pull/349).
```crystal
ws "/:room_name" do |socket, env|
env.params.url["room_name"]
end
```
- Add support for customizing the headers of built-in `Kemal::StaticFileHandler` :hammer: Useful for supporting `CORS` for single page applications :clap:
```crystal
static_headers do |response, filepath, filestat|
if filepath =~ /\.html$/
response.headers.add("Access-Control-Allow-Origin", "*")
end
response.headers.add("Content-Size", filestat.size.to_s)
end
```
- Allow `%w` in Handler macros [#385](https://github.com/kemalcr/kemal/pull/385). Thanks @will :pray:
- Security: `X-Content-Type-Options: nosniff` for static files. Fixes [#379](https://github.com/kemalcr/kemal/issues/379). Thanks @crisward :pray:
- Performance: [Remove tempfile management to OS](https://github.com/kemalcr/kemal/commit/a1520de7ed3865fa73258343a80fad4f20666a99). This brings 10-15% performance boost to Kemal :rocket:
# 0.20.0 (01-07-2017)
- Crystal 0.23.0 support! As always, Kemal is compatible with the latest major release of Crystal 💎
- Great news everyone 🎉 All handlers are now completely ***customizable***!. Use the default `Kemal` handlers or go wild, it's all up to you ⛏
```crystal
# Don't forget to add `Kemal::RouteHandler::INSTANCE` or your routes won't work!
Kemal.config.handlers = [Kemal::InitHandler.new, YourHandler.new, Kemal::RouteHandler::INSTANCE]
```
You can also insert a handler into a specific position.
```crystal
# This adds MyCustomHandler instance to 1 position.
# Be aware that the index starts from 0.
add_handler MyCustomHandler.new, 1
```
- Updated [Kilt](https://github.com/jeromegn/kilt) to v0.4.0.
- Make `Route` a `Struct`. This improves the performance of route declarations.
# 0.19.0 (09-05-2017)
- Return no body for head route fixes [#323](https://github.com/kemalcr/kemal/issues/323). (thanks @crisward)
- Update Radix to `v0.3.8`. (thanks @waghanza)
- User defined context store types. (thanks @neovitange)
```crystal
class User
property name
end
add_context_storage_type(User)
```
- Prevent `send_file` returning filesize. (thanks @crisward)
- Don't call setup in `config#add_filter_handler` fixes [#338](https://github.com/kemalcr/kemal/issues/338).
# 0.18.3 (07-03-2017)
- Remove `Gzip::Header` monkey patch since it's fixed in `Crystal 0.21.1`.
# 0.18.2 (24-02-2017)
- Fix Gzip in Kemal Seems broken for static files [#316](https://github.com/kemalcr/kemal/issues/316). This was caused by `Gzip::Writer` in `Crystal 0.21.0` and currently mitigated by monkey patching `Gzip::Header`.
# 0.18.1 (21-02-2017)
- Crystal 0.21.0 support
- Drop `multipart.cr` dependency. `multipart` support is now built-into Crystal <3
- Since Crystal 0.21.0 comes built-in with `multipart` there are some improvements and deprecations.
- `meta` has been removed from `FileUpload` and it has the following properties:
+ `tmpfile`: This is temporary file for file upload. Useful for saving the upload file.
+ `filename`: File name of the file upload. (logo.png, images.zip e.g)
+ `headers`: Headers for the file upload.
+ `creation_time`: Creation time of the file upload.
+ `modification_time`: Last Modification time of the file upload.
+ `read_time`: Read time of the file upload.
+ `size`: Size of the file upload.
# 0.18.0 (11-02-2017)
- Simpler file upload. File uploads can now be access from `HTTP::Server::Context` like `env.params.files["filename"]`, which exposes following properties.
+ `tmpfile`: This is temporary file for file upload. Useful for saving the upload file.
+ `tmpfile_path`: File path of `tmpfile`.
+ `filename`: File name of the file upload. (logo.png, images.zip e.g)
+ `meta`: Meta information for the file upload.
+ `headers`: Headers for the file upload.
Here's a fully working sample for reading a image file upload `image1` and saving it under `public/uploads`.
```crystal
post "/upload" do |env|
file = env.params.files["image1"].tmpfile
file_path = ::File.join [Kemal.config.public_folder, "uploads/", file.filename]
File.open(file_path, "w") do |f|
IO.copy(file, f)
end
"Upload ok"
end
```
To test
`curl -F "image1=@/Users/serdar/Downloads/kemal.png" http://localhost:3000/upload`
- RF7233 support a.k.a file streaming. [#299](https://github.com/kemalcr/kemal/pull/299) (thanks @denysvitali)
- Update Radix to 0.3.7. Fixes [#293](https://github.com/kemalcr/kemal/issues/293)
- Configurable startup / shutdown logging. [#291](https://github.com/kemalcr/kemal/issues/291) and [#292](https://github.com/kemalcr/kemal/issues/292) (thanks @twisterghost).
# 0.17.5 (09-01-2017)
- Update multipart.cr to 0.1.2. Fixes #285 related to multipart.cr
# 0.17.4 (24-12-2016)
- Support for Crystal 0.20.3
- Add `Kemal.stop`. Fixes [#269](https://github.com/kemalcr/kemal/issues/269).
- `HTTP::Handler` is not a class anymore, it's a module. See https://github.com/crystal-lang/crystal/releases/tag/0.20.3
# 0.17.3 (03-12-2016)
- Handle missing 404 image. Fixes [#263](https://github.com/kemalcr/kemal/issues/263)
- Remove basic auth middleware from core and move to [kemalcr/kemal-basic-auth](https://github.com/kemalcr/kemal-basic-auth).
# 0.17.2 (25-11-2016)
- Use `body.gets_to_end` for `parse_json`. Fixes #260.
- Update Radix to 0.3.5 and lock pessimistically. (thanks @luislavena)
# 0.17.1 (24-11-2016)
- Treat `HTTP::Request` body as an `IO`. Fixes [#257](https://github.com/kemalcr/kemal/issues/257)
# 0.17.0 (23-11-2016)
- Reimplemented Request middleware / filter routing.
Now all requests will first go through the Middleware stack then Filters (`before_*`) and will finally reach the matching route.
Which is illustrated as: `Request -> Middleware -> Filter -> Route`
- Rename `return_with` as `halt`.
- Route declaration must start with `/`. Fixes [#242](https://github.com/kemalcr/kemal/issues/242)
- Set default exception `Content-Type` to `text/html`. Fixes [#202](https://github.com/kemalcr/kemal/issues/242)
- Add `only` and `exclude` paths for `Kemal::Handler`. This change requires that all handlers must inherit from `Kemal::Handler`.
For example this handler will only work on `/` path. By default the HTTP method is `GET`.
```crystal
class OnlyHandler < Kemal::Handler
only ["/"]
def call(env)
return call_next(env) unless only_match?(env)
puts "If the path is / i will be doing some processing here."
end
end
```
The handlers using `exclude` will work on the paths that isn't specified. For example this handler will work on any routes other than `/`.
```crystal
class ExcludeHandler < Kemal::Handler
exclude ["/"]
def call(env)
return call_next(env) unless only_match?(env)
puts "If the path is NOT / i will be doing some processing here."
end
end
```
- Close response on `halt`. (thanks @samueleaton).
- Update Radix to `v0.3.4`.
- `error` handler now also yields error. For example you can get the error mesasage like:
```crystal
error 500 do |env, err|
err.message
end
```
- Update `multipart.cr` to `v0.1.1`
# 0.16.1 (12-10-2016)
- Improved Multipart support with more info on parsed files. `parse_multipart(env)` now yields an `UploadFile` object which has the following properties: `field`, `data`, `meta` and `headers`.
```crystal
post "/upload" do |env|
parse_multipart(env) do |f|
image1 = f.data if f.field == "image1"
image2 = f.data if f.field == "image2"
puts f.meta
puts f.headers
"Upload complete"
end
end
```
# 0.16.0
- Multipart support <3 (thanks @RX14). Now you can handle file uploads.
```crystal
post "/upload" do |env|
parse_multipart(env) do |field, data|
image1 = data if field == "image1"
image2 = data if field == "image2"
"Upload complete"
end
end
```
- Make session configurable. Now you can specify session name and expire time with:
```crystal
Kemal.config.session["name"] = "your_app"
Kemal.config.session["expire_time"] = 48.hours
```
- Session now supports more types. (`String`, `Int32`, `Float64`, `Bool`)
- Add `gzip` helper to enable / disable gzip compression on responses.
- Static file caching with etag and gzip (thanks @crisward)
- `Kemal.run` now accepts port to listen.
# 0.15.1 (05-09-2016)
- Don't forget to `call_next` on `NullLogHandler`
# 0.15.0 (03-09-2016)
- Add context store.
- `KEMAL_ENV` respects to `Kemal.config.env` and needs to be explicitly set.
- `Kemal::InitHandler` is introduced. Adds initial configuration, headers like `X-Powered-By`.
- Add `send_file` to helpers.
- Add mime types.
- Fix parsing JSON params when "charset" is present in `Content-Type` header.
- Use http-only cookie for session.
- Inject `STDOUT` by default in `CommonLogHandler`.
