Automatically creating fake or sample data is a frequent requirement for front-end web developers. Although usually not tedious, there are times when you need to quickly and automatically generate structured data for your html forms or CMS systems for testing purposes.
You can download the library form github and include in your pages where you need to generate the data.
Generating fake data
The API is divided into various sections as show below:
# Name * findName # Address * zipCode * city * streetName * streetAddress * secondaryAddress * ukCounty * ukCountry # PhoneNumber * phoneNumber # Internet * email * userName * domainName * domainWord ...
So if you need to generate a random email address or a zip code you could do it like this:
var randomEmail = Faker.Internet.email(); var randomZip = Faker.Address.zipCode();
Some sample API methods are shown below, but there are more of them which you can find here in the API section.
<script> var longParagraph = Faker.Lorem.paragraphs(); var singleSentence = Faker.Lorem.sentence(); var companyName= Faker.Company.companyName(); var catchPhrase = Faker.Company.catchPhrase(); </script>
One of the interesting methods is ‘ Faker.Company.catchPhrase()’, which generates catchy technological phrases. A kind of a tag line generator for your new multi-million dollar company ;-). A sample output is shown below.

The API also includes several helper methods that lets you create bulk fake data using the single API methods. For example you can generate complete user information templates cards by using a single helper method ‘Faker.Helpers.userCard()’. A sample run is shown below:
name: Blair Nikolaus username: Fernando_Olson email: Jacklyn_Brekke@aurore.name address:street: Kozey Meadow suite: Apt. 664 city: Felipastad zipcode: 88071 phone: 571.540.8605 x136 website: reba.co.uk company:name: Kuhic and Sons catchPhrase: Integrated solution-oriented Graphical User Interface bs: seize scalable web services
The ‘Faker.Helpers.userCard()’ method returns a nested object, so you will need to recursively traverse the object to extract the data. A simple function to do the same is given below:
So now you can do something like this:
... var obj = Faker.Helpers.userCard(); alert( printObj(obj) ); ...
Another Randomizer library
Club AJAX Mock Data Randomizer library is another library that lets you generate random data quickly. This library lets you generate random dates, colors, boolean values which is lacking in the Faker library. Check a simple demo using this library.
