# composium
Powered by
[functional composition](https://en.wikipedia.org/wiki/Function_composition) and
the
[URL Pattern API](https://developer.mozilla.org/en-US/docs/Web/API/URL_Pattern_API),
`composium` has become the most flexible routing framework in the world. Through
its composability it can serve perfectly as a _generic_, _abstract_ and
_minimal_ layer for your own back-end framework.
## URL Pattern
The best way to learn and test the URL Pattern API is Zaubrik's free
[URL Pattern User Interface](https://dev.zaubrik.com/url-pattern/).
## Documentation
```bash
deno doc https://deno.land/x/composium/mod.ts
```
## Example
```ts
import { Context, createDefaultHandler, createGetRoute } from "./mod.ts";
function welcome(ctx: C) {
const name = ctx.result.pathname.groups.name || "nobody";
ctx.response = new Response(`Welcome, ${name}!`);
return ctx;
}
const route = createGetRoute({ pathname: "/{:name}?" })(welcome);
const handler = createDefaultHandler(route);
Deno.serve(handler);
// curl http://localhost:8080/Joe
// Welcome, Joe!
```
