Package description

What is faker?

The faker npm package is a powerful tool for generating massive amounts of fake data in Node.js and the browser. It is commonly used for testing, bootstrapping databases, and creating realistic-looking UI prototypes. Faker can generate data for various categories, including names, addresses, phone numbers, dates, and more.

What are faker's main functionalities?

Generating Names

Generates a random full name. Useful for creating user profiles or contact lists in testing environments.

faker.name.findName();

Generating Addresses

Produces a random street address. This can be used to test address forms or display sample addresses on a map.

faker.address.streetAddress();

Generating Internet-related Information

Creates a random email address. Ideal for testing email validation or populating a database with unique user emails.

faker.internet.email();

Generating Lorem Ipsum Text

Generates random 'Lorem Ipsum' text. This is particularly useful for designers and developers who want to fill their layouts with placeholder text to check text formatting and layouts.

faker.lorem.paragraphs();

Generating Random Numbers

Generates a random number within a specified range. This can be used for creating randomized data points for testing calculations or generating mock analytics data.

faker.random.number({ min: 1, max: 100 });
