Simple HTTP web server

Concepts

  • Use the std library http module to run your own web server.

Overview

With just a few lines of code you can run your own http web server with control over the response status, request headers and more.

Sample web server

In this example, the user-agent of the client is returned to the client:

  1. /**
  2.  * webserver.ts
  3.  */
  4. import { serve } from "https://deno.land/std@$STD_VERSION/http/server.ts";
  6. const server = serve({ hostname: "0.0.0.0", port: 8080 });
  7. console.log(`HTTP webserver running.  Access it at:  http://localhost:8080/`);
  9. for await (const request of server) {
  10.   let bodyContent = "Your user-agent is:nn";
  11.   bodyContent += request.headers.get("user-agent") || "Unknown";
  13.   request.respond({ status: 200, body: bodyContent });
  14. }

Run this with:

  1. deno run --allow-net webserver.ts
