Moment.js using with Require.js

Require.js is a library that is used to load JavaScript files and modules. It is used to improve the speed and quality of your code. We can use Moment.js with Require.js support.

Installation in Node.js:

npm install moment
npm install requirejs

Steps for using Require.js in Node.js:

• Go to any convenient location on your computer and create a new directory named moment-require.
• Open a terminal and type the command:

npm init -y

• Now, open a code editor in the current project directory.
• Edit the package.json as shown in the figure below:

• Now, create a new file named index.js in the current directory.
• Now, import the requirejs module into your project:

var requirejs = require('requirejs');

• Pass the index.js file's "require" function in the configuration to requirejs.

requirejs.config({
    nodeRequire: require,
   baseUrl: __dirname
});

• Now, load a moment.js using require.js as shown in the code below:

var moment=requirejs('moment');

• Create a new date object using the code below:

var dateNow = Date.now();  //Current date object 

• Now, use the moment to format the date using the code below:

var formattedDate = moment(dateNow).format('LLL'); //pass the date object to moment function.

• Print the date into the console using:

console.log (formattedDate); // December 19, 2022 10:47 PM

Example 1:

const requirejs = require('requirejs');

requirejs.config({
    nodeRequire: require,
    baseUrl: __dirname
});
let moment = requirejs('moment');

let dateNow = Date.now();

let formattedDate = moment(dateNow).format('LLL');
console.log(dateNow, formattedDate);

Output:

December 19, 2022 10:47 PM

Example 2:

const requirejs = require('requirejs');

requirejs.config({
    nodeRequire: require,
    baseUrl: __dirname
});
let moment = requirejs('moment');

let dateNow = "2010-10-20 04:30";

let formattedDate = moment(dateNow, 'YYYY-MM-DD H:mm')
    .format('LLL');
console.log(formattedDate);

Output:

October 20, 2010 4:30 AM
