routeno

Small opinionated router for Deno.

• Uses URLPattern for route matching which supports Express-like route params
• Does not extend Request or have any helper functions
• Strives to be very simple and very minimal

Usage

import { createRouter } from "https://deno.land/x/routeno@0.0.1/mod.ts"
import { serve } from "https://deno.land/std@0.145.0/http/mod.ts";

function getProject(req: Request, params: Record<'id', string>) {
  return new Response(getProjectById(params.id));
}

const router = createRouter({
  '/api/projects': {
    'GET': getProjects,
    'POST': createProject
  },
  '/api/projects/:id': {
    'GET': getProject,
  },
  '/api/check': check, // Will respond to any HTTP method
})

await serve(router);

Design

Goal is to have tiny wrapper around standard Request, Response and URLPattern workflow.

It doesn't have middleware interface (e.g. router.get('/route', endpoint)) and accepts mapping object instead.

Router does not extend default Request object and instead passes route params as second argument to handler function.

Performance

This router written to be as fast as possible while using URLPattern (which uses path-to-regexp), which is slower than, e.g. using Radix Trees or RegEx for matching.

Benchmark script with comparison to several popular Deno routers is available. Run it with deno bench --unstable.
