How to create different post request using Node.js ?

Last Updated : 25 Dec, 2020

A POST request is one of the important requests in all HTTP requests. This request is used for storing the data on the WebServer. For Eg File uploading is a common example of a post request. There are many approached to perform an HTTP POST request in Node.js. Various open-source libraries are also available for performing any kind of HTTP request.

There are three approaches to create different post requests are discussed below.

Using Needle Module
Using axiom Module
Using https Module

Below all three approaches all discussed in detail:

Approach 1: One of the ways of making an HTTP POST request in Node.js is by using the Needle library. Needle is a HTTP client for making HTTP requests in Node.js , multipart form-data (e.g. file uploads) , automatic XML & JSON parsing etc.

Project structure:

Installing module:

npm install needle

Index.js

JavaScript

//Importing needle module
const needle = require('needle');

// Data to be sent
const data = {
    name: 'geeksforgeeks',
    job: 'Content Writer',
    topic:'Node.js'
};

// Making post request
needle('post', 'https://requires.in/api/usersdata', 
    data, {json: true})
    .then((res) => {

        // Printing the response after request
        console.log('Body: ', res.body);
    }).catch((err) => {

        // Printing the err
        console.error(err.Message);
    }
);

Execution command:

node index.js

Console Output:

Approach 2: Another library that can be used is Axios. This is a popular node.js module used to perform HTTP requests and supports all the latest browsers. It also supports async/await syntax for performing a POST request.

Installing module:

npm install axios

Index.js

JavaScript

// Importing the axios module
const axios = require('axios');

// Data to be sent
const data = {
    name: 'geeksforgeeks',
    job: 'Content Writer',
    topic: 'Node.js'
};

const addUser = async () => {
    try {

        // Making post request 
        const res = await axios.post(
'https://reqres.in/api/usersdata', data);

        // Printing the response data   
        console.log('Body: ', res.data);
    } catch (err) {

        // Printing the error
        console.error(err.Message);
    }
};

Execution command:

node index.js

Console Output:

Approach 3: It is also possible to perform a POST request using Node.js built-in HTTPS module. This module is used for sending the data in an encrypted format

Index.js

JavaScript

// Importing https module
const https = require('https');

// Converting data in JSON format
const data = JSON.stringify({
    name: 'geeksforgeeks',
    job: 'Content Writer',
    topic:'Node.js'
});

// Setting the configuration for
// the request
const options = {
    hostname: 'reqres.in',
    path: '/api/users',
    method: 'POST'
};

// Sending the request
const req = https.request(options, (res) => {
    let data = '';
 
    res.on('data', (chunk) => {
        data += chunk;
    });

    // Ending the response 
    res.on('end', () => {
        console.log('Body:', JSON.parse(data));
    });
   
}).on("error", (err) => {
    console.log("Error: ", err.message);
});

// Write data to request body
req.write(data);
req.end();
