Fixture Maker

FixtureMaker is a simple package made to help you create fixture files (for testing, creating sample data etc). Currently, the fixtures are only made in json format.

Installation

This is available as an npm package.

npm i -D fixture-maker

Usage

// 1. Require the package
const FixtureMaker = require("fixture-maker");
const fixtureMaker = new FixtureMaker();

// 2. Define the shape of your fixture
const fixtureBody = {
  firstName: fixtureMaker.string({ chars: 10 }),
  phones: fixtureMaker.randomNumber({ between: 100, and: 500 }),
  id: fixtureMaker.uuid(),
  date: fixtureMaker.randomDate({ between: "01-01-1980", and: "01-09-2019" })
};

// 3. Create your fixture file
fixtureMaker.make({
  body: fixtureBody,
  numberOfCopies: 100,
  filename: "helloworld"
});

Note: Currently, fixture-maker only supports objects with one level of nested objects.
