class Router
import { Router } from "https://dotland.deno.dev/x/wmill@v1.354.0/deps.ts";

An interface for registering middleware that will run when certain HTTP methods and paths are requested, as well as provides a way to parameterize parts of the requested path.

Basic example

import { Application, Router } from "https://deno.land/x/oak/mod.ts";

const router = new Router();
router.get("/", (ctx, next) => {
  // handle the GET endpoint here
});
router.all("/item/:item", (ctx, next) => {
  // called for all HTTP verbs/requests
  ctx.params.item; // contains the value of `:item` from the parsed URL
});

const app = new Application();
app.use(router.routes());
app.use(router.allowedMethods());

app.listen({ port: 8080 });

allowedMethods(options?: RouterAllowedMethodsOptions): Middleware

Middleware that handles requests for HTTP methods registered with the router. If none of the routes handle a method, then "not allowed" logic will be used. If a method is supported by some routes, but not the particular matched router, then "not implemented" will be returned.

The middleware will also automatically handle the OPTIONS method, responding with a 200 OK when the Allowed header sent to the allowed methods for a given route.

By default, a "not allowed" request will respond with a 405 Not Allowed and a "not implemented" will respond with a 501 Not Implemented. Setting the option .throw to true will cause the middleware to throw an HTTPError instead of setting the response status. The error can be overridden by providing a .notImplemented or .notAllowed method in the options, of which the value will be returned will be thrown instead of the HTTP error.

const router = new Router();

// register routes

app.use(router.routes());
app.use(router.allowedMethods());
await app.listen({ port: 80 });
