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.
The best way to learn and test the URL Pattern API is Zaubrik's free URL Pattern User Interface.

import { Context, createDefaultHandler, createGetRoute } from "./mod.ts"; function welcome<C extends Context>(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!
