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');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 …;import/export js functions
// helloworld.js
export function helloWorld() {
return 'Hello World!';
}
// main.js
import helloWorld from './helloworld.js';
console.log(helloWorld());js class export
export class ClassName {...}Copyright © 2021 Codeinu
