Chance - Random generator helper for JavaScript

Homepage: http://chancejs.com

Many more details on http://chancejs.com but this single library can generate random numbers, characters, strings, names, addresses, dice, and pretty much anything else.

It includes the basic building blocks for all these items and is built on top of a Mersenne Twister so it can generate these things with repeatability, if desired.


See the full docs for details on installation and usage.

Dependent tools

  • Chance CLI - Use Chance on the command line.
  • Chance Token Replacer - Replace tokens in a string with Chance generated items.
  • Dream.js - Lightweight json data generator
  • Fake JSON Schema - Use chance generators to populate JSON Schema samples.
  • Mocker Data Generator - Minimal JSON data generator.
  • swagger-mock-api - Generate API mocks from a Swagger spec file enriched with Chance types and constraints
  • fony - A simple command line tool for generating fake data from a template string

Or view all of the dependents on npm
