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. 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.

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

• 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

• Handle missing 404 image. Fixes #263
• Remove basic auth middleware from core and move to kemalcr/kemal-basic-auth.

• 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

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
• Set default exception Content-Type to text/html. Fixes #202
• 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.

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 /.

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

  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.

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.

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

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.
