mockimocki

Mock data switch

Mockimocki works as a simple switch between real data and mock data. You provide both as functions and choose - either globally or locally - what to supply, mockimocki gives it back.

Import

Either

  import { mockimocki, supply } from 'mockimocki';
  // Or
  import mockimocki from 'mockimocki';

  // Then
  mockimocki(...);
  mockimocki.mockimocki(...); // Same as `mockimocki(...)`
  mockimocki.supply(...);

Or

  const { mockimocki, supply } = require('mockimocki');
  // Or
  const mockimocki = require('mockimocki');

  // Then
  mockimocki(...);
  mockimocki.mockimocki(...); // Same as `mockimocki(...)`
  mockimocki.supply(...);

Usage

  function getMyRecord (id) {
    return mockimocki(
      () => getRealRecord(id),
      () => getMockRecord(id)
    );
  }

To globally set what kind of data you want to supply when calling the mockimocki function, use the supply() function:

  mockimocki.supply('real');
  // Or
  mockimocki.supply('mock');

The mockimocki() function accepts a third argument, an object of options, where you can specify what data to use, locally overriding the choice you made:

function getMyRecord (id) {
  return mockimocki(
    () => getRealRecord(id),
    () => getMockRecord(id),
    { force: 'mock' }
  );
}

This can come in handy during debugging, where you only want (not) to mock a specific piece of data.

API

mockimocki(real, mock, [opts])

Return either the result of real() or mock().

Arguments

• real: A function returning the real data
• mock: A function returning the mock data
• opts: An object of options

Options

Currently only the force option is provided, which can assume the same value as the what parameter of supply(). force is used to locally override the type of data you want the mockimocki() function to return. Every time some data is forced, a warning is emitted on the console.

supply(what)

Choose what data to supply globally.

Arguments

• what: either 'real' or 'mock'
