Charon is designed to act as an API Gateway for a service-oriented architecture. It's my first personal attempt at a useful piece of software written in Go. Because of that, the code might not be great and there will be little to no testing.
Charon acts as both a router and a proxy. Given a set of defined services that each have a defined routing rule, it will proxy any HTTP requests that match a rule to the respective service.
Config is handled entirely through a TOML-based config file. It's very simple and has only a few options:
port = "9000"
service_timeout = "30s"
[services]
[services.member]
url = "http://users.charon.io"
prefix = "/users/*"
The value for prefix is important, as it defines how the internal router will route requests to each specific service. With the above config, any request to http://gateway.charon.io with a path that matches /users, e.g. http://gateway.charon.io/users/1 will be proxied to the service at http://users.charon.io/users/1.
