::: cowboy_router
The `cowboy_router` middleware maps the requested host and
path to the handler to be used for processing the request.
It uses the dispatch rules compiled from the routes given
to the `compile/1` function for this purpose. It adds the
handler name and options to the environment as the values
`handler` and `handler_opts` respectively.
Environment input:
* dispatch = dispatch_rules()
Environment output:
* handler = module()
* handler_opts = any()
:: Types
: bindings() = [{atom(), binary()}]
List of bindings found during routing.
: dispatch_rules() - opaque to the user
Rules for dispatching request used by Cowboy.
: routes() = [{Host, Paths} | {Host, cowboy:fields(), Paths}]
Types:
* Host = Path = '_' | iodata()
* Paths = [{Path, Handler, Opts} | {Path, cowboy:fields(), Handler, Opts}]
* Handler = module()
* Opts = any()
Human readable list of routes mapping hosts and paths to handlers.
The syntax for routes is defined in the user guide.
: tokens() = [binary()]
List of host_info and path_info tokens found during routing.
:: Exports
: compile(Routes) -> Dispatch
Types:
* Routes = routes()
* Dispatch = dispatch_rules()
Compile the routes for use by Cowboy.
