# 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.
