Build an API in 1 minute

Creating a REST API using Node.js and Express is incredibly easy and quick. In this tutorial, we’ll show you how to set up a basic API in just one minute.

Step 1: Install Node.js and Express

If you haven’t already, make sure to install Node.js and npm on your computer. You can then create a new directory for your API project and run npm install express to install the Express framework.

Step 2: Create your API file

Create a new file, for example app.js, and include the following code:

    
      const express = require('express');
      const app = express();

      app.get('/', (req, res) => {
        res.send('Hello, this is your API!');
      });

      app.listen(3000, () => {
        console.log('Server is running on port 3000');
      });
    
  

Step 3: Start your API

Run your API using the command node app.js. Your API will now be running on port 3000. You can access it by going to http://localhost:3000 in your web browser.

That’s it!

Congratulations, you’ve just built a basic REST API in just one minute! Of course, this is just the beginning and there’s a lot more you can do with Node.js and Express to create robust and powerful APIs. But this simple example should give you a good starting point.

Happy coding!
