Deploy Express server

Express is a fast, unopinionated, minimalist web framework for Node.js designed for building web applications and APIs.

Follow the steps below to deploy your Flask app on Replit:

Step 1: Fork the ExpressJS template by using the button + Use Template on Replit. In the Repl, you’ll see the code used for deployment.

  import express from 'express';

const app = express();

app.get('/', (req, res) => {
res.send('Hello World!');
});

app.listen(3000, () => {
console.log('Express server initialized');
});

Step 2: In the workspace header, select Deploy button and choose Autoscale from the types of deployments. Then, select the Set up your deployment button.

Step 3: Use the following configuration during your setup:

  • Machine configuration: You can keep the default values. The default machine configuration is a 1vCPU and 2 GiB RAM.
  • Select the Approve and configure build settings button to continue with the build settings.

Step 4: In the tab that opens, the Type is defaulted to the selected deployment type. Here it is Autoscale. You can select Manage to change the type of deployment:

  • Primary domains: Choose a domain name for your app.
  • Build command: This is an optional command. You can leave it blank.
  • Run command: Enter the command node index.js into the Run command field.
  • Select the Deploy button to start the deployment process.

After a few minutes, your app will be live!

In the future, whenever you want to change your live deployment, you can change the deployment options by selecting the Manage button and then selecting the Approve and update button. You can also use the Redeploy button in the workspace header to deploy your application again.
