Example 3: Exporting Function
Create a file named as app.js and export the function using module.exports
.
module.exports = function (a, b) {
console.log(a + b);
}
Create a file named as index.js and import the file app.js to use the exported function.
const sum = require('./app');
sum(2, 5);
Output:
7
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 module’s 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:
