How to send get and post request in API using Node JS & using Postman

This article covers the topic of How to send get and post request in API using Node JS & using Postman

1. Install Axios:

First, we need to install the Axios library. we can do this by running the given command in our Node.js project directory:

npm install axios

2. Sending GET and POST Requests in Node.js:

Here’s how we can send GET and POST requests in Node.js using Axios:

// Import the Axios library
const axios = require('axios');

// Example GET request
axios.get('https://jsonplaceholder.typicode.com/posts/1')
    .then(response => {
        console.log('GET Request Response:', response.data);
    })
    .catch(error => {
        console.error('Error:', error);
    });

// Example POST request
axios.post('https://jsonplaceholder.typicode.com/posts', {
        title: 'foo',
        body: 'bar',
        userId: 1
    })
    .then(response => {
        console.log('POST Request Response:', response.data);
    })
    .catch(error => {
        console.error('Error:', error);
    });

This code sends a GET request to retrieve a post with ID 1 from JSONPlaceholder and a POST request to create a new post.

3. Testing with Postman:

To test these requests with Postman:

1. Open Postman.
2. Create a new request.
3. Set the request type to GET or POST as needed.
4. Enter the URL for the API endpoint you want to test.
5. Click on “Send” to send the request.
6. You should see the response in the Postman interface.
