Configuration

The server is configured using a YAML file. Follows a nginx-like structure. The following is an example configuration (and the default loaded when no arg is provided):

servers:
  - listen: 8080
    server_names: localhost
    default: true
    routes:
      - uri: /
        settings:
          methods: [GET, HEAD]
        modules:
          - type: static
            settings:
              root: ~
              directory_listing: true

listen: Port to listen on, can be a single port or a list of ports.
server_names: List of server names that the server will respond to.
default: If true, this server will be the default one (requests sent to a interface with no server conf match will be sent to this one instead).
routes: List of routes.
uri: URI to match.
settings: Route settings.
- methods: List of allowed methods. If empty (or not set), all methods are allowed.
modules: List of modules to be executed for this route. The order is important.
- type: Module type.
- settings: Module settings.
