Web

AI web app and API generator on Node and Express

Describe the service you want and Devellix writes the Node and Express code, defines the routes, installs the dependencies, and bundles a runnable build, with the full source you own.

Node.jsExpressREST APInpmBundled build

Standing up a backend service means the same setup every time: an Express app, routing, middleware, a dependency tree, and a build that runs. Devellix takes a description of what the service should do and produces that project, structured the way a maintained Node app is.

The dependencies are installed and the app is bundled in the cloud, so what you download is a service that starts, not a scaffold with missing pieces. The complete source ships with every build for you to host, extend, and own.

  • Generates Node and Express apps and REST APIs from a description
  • Routes, handlers, and middleware wired together
  • Dependencies installed and the project validated in the cloud
  • A bundled, runnable build plus the full source you own
  • Sensible project layout you can extend
  • Live transcript of the plan, files, and build

A real Web build

One sentence in, a working project out. This is an actual file from a Devellix build, not a mockup.

Prompt

A REST API for a URL shortener with POST /shorten and a redirect route

server.js Dependencies installed, runnable build
const express = require("express");
const crypto = require("crypto");

const app = express();
app.use(express.json());

const links = new Map();

app.post("/shorten", (req, res) => {
  const { url } = req.body;
  if (!url || !url.startsWith("http")) {
    return res.status(400).json({ error: "A valid http url is required." });
  }
  const code = crypto.randomBytes(4).toString("base64url");
  links.set(code, url);
  res.status(201).json({ code, short: "/" + code });
});

app.get("/:code", (req, res) => {
  const target = links.get(req.params.code);
  if (!target) return res.status(404).json({ error: "Not found." });
  res.redirect(target);
});

app.listen(3000, () => console.log("URL shortener on :3000"));

What you get

Express, done properly

Services are built on Node and Express with real routing and middleware, structured like a project you would maintain, not a single-file demo.

Endpoints from a sentence

Describe the endpoints you need and Devellix defines the routes and handlers, with request handling and responses wired in.

Installs and bundles

The dependency tree is installed and the app is bundled in the cloud, so what you download runs instead of erroring on a missing package.

Host it anywhere

You own the full source. Deploy it on any Node host, extend it, and keep it in your own repository. No proprietary runtime.

Frequently asked

Yes. Describe the service and Devellix writes a Node and Express project, installs its dependencies, bundles a runnable build, and gives you the source.
Yes. Every build ships with its full Node source, which you own and can host, edit, and extend anywhere.
Web builds are generated on Node and Express, with a project layout and dependencies you can run and extend right away.
The dependencies are installed and the app is bundled in the cloud, so it starts as-is. You add any environment values it needs and run it.
