    Please replace your faker dependency with @faker-js/faker. This is the official, stable fork of Faker.

    npm install @faker-js/faker --save-dev

    or yarn

    yarn add @faker-js/faker -D

    or pnpm

    pnpm install @faker-js/faker -D

      const randomName = faker.name.findName(); // Caitlyn Kerluke
      const randomEmail = faker.internet.email(); // Rusty@arne.info
      const randomCard = faker.helpers.createCard(); // random contact card containing many properties


    const { faker } = require('@faker-js/faker');
    const randomName = faker.name.findName(); // Rowan Nikolaus
    const randomEmail = faker.internet.email(); // Kassandra.Haley@erich.biz
    const randomCard = faker.helpers.createCard(); // random contact card containing many properties


    import { faker } from "https://cdn.skypack.dev/@faker-js/faker";
    const randomName = faker.name.findName(); // Willie Bahringer
    const randomEmail = faker.internet.email(); // Tomasa_Ferry14@hotmail.com
    const randomCard = faker.helpers.createCard(); // random contact card containing many properties

    TypeScript Support

    Since version v6+ there is native TypeScript support.

    If you want for whatever reason the versions prior to v6, you can use @types/faker and rebind the declarations to the @faker-js/faker package with a faker.d.ts file in your e.g. src folder.

    // faker.d.ts
    declare module '@faker-js/faker' {
      import faker from 'faker';
      export default faker;

    Faker contains a super useful generator method Faker.fake for combining faker API methods using a mustache string format.


      faker.fake('{{name.lastName}}, {{name.firstName}} {{name.suffix}}')

    This will interpolate the format string with the value of methods name.lastName(), name.firstName(), and name.suffix()


    Faker has support for multiple locales.

    The default language locale is set to English.

    Setting a new locale is simple:

    // sets locale to de
    faker.locale = 'de';

    See our documentation for a list of provided languages

    Individual Localization Packages

    Faker supports incremental loading of locales.

    // loads only de locale
    const faker = require('@faker-js/faker/locale/de');

    Setting a randomness seed

    If you want consistent results, you can set your own seed:

    const firstRandom = faker.datatype.number();
    // Setting the seed again resets the sequence.
    const secondRandom = faker.datatype.number();
    console.log(firstRandom === secondRandom);


    Building Faker

    The project is being built by esbuild (see bundle.ts)

    pnpm install
    pnpm run build


    pnpm install
    pnpm run build
    pnpm run test
    # or
    pnpm run coverage

    You can view a code coverage report generated in coverage/index.html.

    Developing the docs
