Deploy a Node.js Express App on Leapcell

Quickly deploy your Node.js Express app on Leapcell in a few steps. Use our example app or your own.

1. Fork the Express.js boilerplate on GitHub.

Here’s the app.js file from that repo, which is borrowed from the official Express docs:

const express = require('express');

const app = express();

app.get("/hello", (request, response) => {
    return response.send("Hello Leapcell");
});

app.listen(8080, () => {
    console.log('App is listening on port 8080');
});

2. Create a Service in the Leapcell Dashboard and connect your new repo.

Go to the Leapcell Dashboard and click the New Service button.

Then click Connect with GitHub and select the forked repository.

3. Provide the following values during creation:

Field	Value
Runtime	Node.js (Any version)
Build Command	npm install
Start Command	node app.js
Port	8080

4. Access Your App:

Once deployed, you should see a URL like foo-bar.leapcell.dev on the Deployment page. Visit the domain shown on the service page.

Continuous Deployments

Every push to the linked branch automatically triggers a build and deploy. Failed builds are safely canceled, leaving the current version running until the next successful deploy.
