Playing with APIs

Lecture 361:- Playing with APIs

To render an API, you need to create a route that will respond to HTTP requests with data in a particular format such as JSON. Here's an example of how you can render an API using Node.js and Express:

javascriptCopy code

const express = require('express'); const app = express(); const products = [  { id: 1, name: 'Product 1', price: 10 },  { id: 2, name: 'Product 2', price: 20 },  { id: 3, name: 'Product 3', price: 30 } ]; app.get('/api/products', (req, res) => {  res.json(products); }); const port = process.env.PORT || 3000; app.listen(port, () => {  console.log(`Listening on port ${port}...`); });

In the example above, we have created an Express app and defined an array of products. We then created a route to handle GET requests to the URL /api/products. When a GET request is made to this URL, the server responds with the products array in JSON format using the res.json() method.

To test this API, you can use a tool like Postman to make a GET request to http://localhost:3000/api/products, which will return the array of products in JSON format.
