How to create different post request using Node.js ?
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
//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
// 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
// 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();
Execution command:
node index.js
Console output:
