In this article, we would like to show you how to export class from module in Node.js.

Below we present how to export class from module1.js to index.js file.

Project structure:

/my-app/
   ├── index.js
   ├── user.js
   └── package.json

Steps to follow:

1. In module1.js file export the class using module.exports.

Practical example:

module.exports = class User {
    constructor(id, name, age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }
 
    display() {
        console.log(`id: ${this.id}, name: ${this.name}, age: ${this.age}`);
    }
 }

2. In index.js file import the class from module1.js using require(). From now you can create class objects and use its methods as presented below.

Practical example:

const User = require('./user');

const user1 = new User(1, 'Tom', 23);

user1.display();

3. Now you can run the project from terminal to see the output using the following command:

node index.js

Output:

id: 1, name: Tom, age: 23
