- Allow to set filename for `send_file` [#512](https://github.com/kemalcr/kemal/pull/512). Thanks @mamantoha :pray:
```ruby
send_file env, "./asset/image.jpeg", filename: "image.jpg"
```
- Set `status_code` before response [#513](https://github.com/kemalcr/kemal/pull/513). Thanks @mamantohoa :pray:

# 0.25.1 (06-10-2018)
- Fix `params.files` memoization https://github.com/kemalcr/kemal/pull/503. Thanks @mamantoha :pray:
# 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: 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
```ruby
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:
```ruby
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 🙏
```ruby
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
```

# 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 ⛏
```ruby
# 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.
```ruby
# 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.

# 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](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"]`.
`env.params.files["filename"]` has 5 methods
- `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. (https://github.com/kemalcr/kemal/pull/299) (thanks @denysvitali)
- Update Radix to 0.3.7. Fixes https://github.com/kemalcr/kemal/issues/293
- Configurable startup / shutdown logging. https://github.com/kemalcr/kemal/issues/291 and 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.
- `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
- 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/sdogruyol/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/sdogruyol/kemal/issues/242)
- Set default exception Content-Type to text/html. Fixes [#202](https://github.com/sdogruyol/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`,`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 wit
```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
