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`.

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 ⛏ ```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. - 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. (thanks @crisward) - Update `radix` to `0.3.8`. (thanks @waghanza) - User defined context store types. (thanks @neovitange) ```ruby class User property name end add_context_storage_type(User) ``` - Prevent `send_file returning filesize. (thanks @crisward) - Dont call setup in `config#add_filter_handler` fixes #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](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
