Yeager

Simple router implementation w/http handler for Crystal, named after "Router Man" - William Yeager. It supports basic router requirements with speed.

While the Yeager::Router provides a basic router functionality, Yeager::App aims to provide similar interface with Express.js 4.x on top of Yeager::Router and built-in HTTP module.

Usage

Router only

require "yeager"

# Create router instance
router = Yeager::Router.new

# Define your routes
router.add "/foo"
router.add "/foo/:hello"

# Run a route on router which will return nil or an
# Hash(Symbol | String => String) if there is a match
router.run "/foo"       # -> {:path => "/foo"}
router.run "/foo/world" # -> {"hello" => "world", :path => "/foo/:hello"}
router.run "/bar"       # -> nil

Web application with Yeager::App

require "yeager"

# Create the app
app = Yeager::App.new

# Add a glob handler to call before everything else
# will print "A new visit!" for each request
app.get "*" do |req, res, continue|
  puts "A new visit!"
  continue.call
end

# Add GET handler for "/" to response back with "Hello world!"
app.get "/" do |req, res|
  res.send "Hello world!"
end

# Redirect GET requests to "/google" to https://google.com
app.get "/google" do |req, res|
  res.redirect "https://google.com"
end

# Response with JSON on GET requests to "/json"
app.get "/json" do |req, res|
  res.status(200).json({"Hello" => "world!"})
end

# Add another GET handler for "/:user"
# which will render "Hello yeager!" for "/yeager" route
app.get "/:user" do |req, res|
  res.send "Hello #{req.params["user"]}!"
end

# Enable CORS
app.use do |req, res, continue|
  res.headers.add "Access-Control-Allow-Origin", "*"
  continue.call
end

# Start the app on port 3000
app.listen 3000 do
  print "Example app listening on 0.0.0.0:3000!"
end
