xfw: all-in-one REST API

xfw is a self-working API coded in Go:

• It allows anyone to create a fully featured REST API
• it can be used in Go as a library, or as a proxy to launch external commands (e.g. php scripts)

It is based on the all-in-config idea, where you only have a configuration file, and your implementation and it works without no further work.

Here's a taste of some features:

• human-readable json configuration
• nested routes (i.e. /user/:id: vs. /user/post/​:id:​)
• useful http methods: GET, POST, PUT, DELETE
• manage URL, query and body arguments:
  • multipart/form-data
  • application/x-www-form-urlencoded
  • application/json
• required vs. optional parameters with a default value
• parameter renaming
• generic authentication system (i.e. you can override the built-in)
• generic type check (i.e. implement your types alongside built-in types)
