# Welcome to the trillium router crate!

This router is built on top of
[routefinder](https://github.com/jbr/routefinder), and the details of
route resolution and definition are documented on that repository.

```
use trillium::{conn_unwrap, Conn};
use trillium_router::{Router, RouterConnExt};

let router = Router::new()
    .get("/", |conn: Conn| async move { conn.ok("you have reached the index") })
    .get("/pages/:page_name", |conn: Conn| async move {
        let page_name = conn_unwrap!(conn.param("page_name"), conn);
        let content = format!("you have reached the page named {}", page_name);
        conn.ok(content)
    });

use trillium_testing::prelude::*;
assert_ok!(get("/").on(&router), "you have reached the index");
assert_ok!(get("/pages/trillium").on(&router), "you have reached the page named trillium");
assert_not_handled!(get("/unknown/route").on(&router));
```

Although this is currently the only trillium router, it is an
important aspect of trillium's architecture that the router uses only
public apis and is interoperable with other router implementations. If
you have different ideas of how a router might work, please publish a
crate! It should be possible to nest different types of routers (and
different versions of router crates) within each other as long as they
all depend on the same version of the `trillium` crate.

## Options handling

By default, the trillium router will reply to an OPTIONS request with
the list of supported http methods at the given route. If the OPTIONS
request is sent for `*`, it responds with the full set of http methods
supported by this router.

**Note:** This behavior is superceded by an explicit OPTIONS handler
or an `any` handler.

To disable the default OPTIONS behavior, use
[`Router::without_options_handling`] or
[`RouterRef::set_options_handling`]
