How to Get JSON Response from REST API in Node.js

To get a JSON response from a REST API in Node.js, you can follow these steps:

  1. Install the necessary dependencies: Before making API requests, you need to install the required dependencies. The most common package used for making HTTP requests in Node.js is axios. You can install it by running the following command in your terminal: npm install axios

  2. Import the axios module: In your Node.js file, you need to import the axios module to use its functionality. You can do this by adding the following line at the top of your file: javascript const axios = require('axios');

  3. Make an HTTP GET request: To retrieve data from a REST API, you need to make an HTTP GET request to the API endpoint. You can use the axios.get() method to send the GET request. Pass the URL of the API endpoint as an argument to the get() method. Here's an example: javascript axios.get('https://api.example.com/data') .then(response => { // Handle the response data here console.log(response.data); }) .catch(error => { // Handle any errors that occur during the request console.error(error); });

  4. Handle the response: In the .then() method, you can access the response data using the response.data property. You can then process or manipulate the data as needed. In the example above, the response data is logged to the console.

  5. Handle errors: In the .catch() method, you can handle any errors that occur during the request. If an error occurs, it will be passed as an argument to the .catch() method. In the example above, any errors that occur during the request will be logged to the console.

That's it! With these steps, you can make an HTTP GET request to a REST API in Node.js and retrieve a JSON response.
