Example 4: Exporting function as a class
Create a file named as app.js. Define a function using this keyword and export the function using module.exports and
Create a file named index.js and import the file app.js to use the exported function as a class.
Javascript
const Company = require( './app' ); const firstCompany = new Company(); firstCompany.info(); |
Javascript
module.exports = function () { this .name = 'w3wiki' ; this .website = 'https://w3wiki.org' ; this .info = () => { console.log(`Company name - ${ this .name}`); console.log(`Website - ${ this .website}`); } } |
Output:
Company name - w3wiki
Website - https://w3wiki.org
Node Export Module
In Node, the `module.exports` is utilized to expose literals, functions, or objects as modules. This mechanism enables the inclusion of JavaScript files within Node.js applications. The `module` serves as a reference to the current module, and `exports` is an object that is made accessible as the moduleās public interface.
Syntax:
module.exports = literal | function | object
Note: Here the assigned value (literal | function | object) is directly exposed as a module and can be used directly.
Syntax:
module.exports.variable = literal | function | object
Note: The assigned value (literal | function | object) is indirectly exposed as a module and can be consumed using the variable.
Below are different ways to export modules:
