js export module code example

Example 1: node js module export class

module.exports = class Person {
	constructor(firstName, lastName) {
		this.firstName = firstName;
		this.lastName = lastName;
	}

	display() {
		console.log(this.firstName + " " + this.lastName);
	}
}

Example 2: What is the syntax to export a function from a module in Node.js

function foo() {}
function bar() {}

// To export above functions:
module.exports = foo;
module.exports = bar;

// And in the file you want to use these functions,
// import them like this:
const foo = require('./module/path');
const bar = require('./module/path');

Example 3: how to export module in node js

module.exports ={
 //functions
}

Example 4: import and export type in js

// Exporting individual features
export let name1, name2, …, nameN; // also var, const
export let name1 = …, name2 = …, …, nameN; // also var, const
export function functionName(){...}
export class ClassName {...}

// Export list
export { name1, name2, …, nameN };

// Renaming exports
export { variable1 as name1, variable2 as name2, …, nameN };

// Exporting destructured assignments with renaming
export const { name1, name2: bar } = o;

// Default exports
export default expression;
export default function (…) { … } // also class, function*
export default function name1(…) { … } // also class, function*
export { name1 as default, … };

// Aggregating modules
export * from …; // does not set the default export
export * as name1 from …; // Draft ECMAScript® 2O21
export { name1, name2, …, nameN } from …;
export { import1 as name1, import2 as name2, …, nameN } from …;
export { default } from …;

Example 5: export function javascript

// module "mon-module.js"
export default function cube(x) {
  return x * x * x;
}
