Random Data Generator In JavaScript – offhand

Preview:

Description:

Generating random data (also called dummy data or fake data) for development, testing and exposure is a pretty common activity in the software business.

offhand is a JavaScript-powered random data generator that allows you to easily generate example data in various formats, such as colors, numbers, dates, times, letters, strings, credit card details, and much more.

I’ve been using this random data generator for several projects and found it extremely handy. I hope you’ll find it useful, too.

Table Of Contents:

• Address
• Color
• Credit Card
• Date & Time
• Number
• Letter

How to use it:

1. Install & download.

# NPM
$ npm i @ebflat9/offhand

2. Import the offhand.

import { Offhand } from '@ebflat9/offhand'

// Or browser:
<script type="module">
  import { Offhand } from './dist/index.js'
</script>

3. Initialize the offhand and set the local.

const offhand = Offhand.setup({ 
      locale: 'en-US' 
})

4. Generate a random number.

offhand.randomGenerator.from([1, 2, 3])
// randomNumbers() => 3
// randomNumbers() => 1
// randomNumbers() => 2
offhand.randomizer.randomDigit();
// => 0.71'
offhand.replacer.numberify('####-####')
// => 6210-1900

5. Generate random dates.

offhand.date.random('MM-DD-YYYY');
// => 12/19/1969, 4:39:44 PM
offhand.date.century();

6. Generate random letters.

offhand.replacer.letterify('XXXX-XXXX');

7. Generate random credit card details.

offhand.color.rgbArray()
// => [163, 64, 109]
offhand.color.rgbaArray()

offhand.color.rgb();
// => rgb(215, 37, 120)
offhand.color.rgba();
