Routing

One of the coolest things about the Request/Response API is that it works with modern web frameworks, so you can use routing and their helper methods!

Hono

Here’s an example with Hono:

import { Hono } from "npm:hono@3";

const app = new Hono();
app.get("/", (c) => c.text("Hello world!"));
app.get("/yeah", (c) => c.text("Routing!"));
export default app.fetch;

Peko

And one with Peko:

import { Peko } from "https://deno.land/x/peko@2.0.0/mod.ts";

export const pekoExample = async (request) => {
  const server = new Peko.Router();
  server.get("/", () => new Response("Yes? There's something at /hello"));
  server.get("/hello", () => new Response("Hello world!"));
  return server.requestHandler(request);
};

nhttp

And nhttp:

import { nhttp } from "npm:nhttp-land@1";

export const nhttpExample = async (request) => {
  const app = nhttp();
  app.get("/", () => {
    return "Hello, World";
  });
  app.get("/cat", () => {
    return { name: "cat" };
  });
  return app.handleRequest(request);
};

itty-router

A super tiny example with itty-router:

import { Router, json } from "npm:itty-router@4";

export const ittyRouterExample = async (request: Request) => {
  const router = Router();
  router.get("/", () => "Hi");
  return router.handle(request).then(json);
};

feTS

A simple example of using feTS server:

import { createRouter, Response } from "npm:fets";

export const router = createRouter().route({
  method: "GET",
  path: "/greetings",
  schemas: {
    responses: {
      200: {
        type: "object",
        properties: {
          message: {
            type: "string",
          },
        },
        required: ["message"],
        additionalProperties: false,
      },
    },
  },
  handler: () => Response.json({ message: "Hello World!" }),
});

export default router.fetch;

Notice, that it exports the router, which allows to use the feTS client to make routes type safe:

import { type router } from "https://esm.town/v/user/fetsServer";
import { createClient } from "npm:fets";

const client = createClient<typeof router>({
  endpoint: "https://user-fetsServer.web.val.run",
});

// The `response` and `greetings` have proper types automatically inferred
const response = await client["/greetings"].get();
const greetings = await response.json();
console.log(greetings);
