Happo Target: React Native

Installation

If you haven't already installed happo you will need to do that:

npm install --save-dev happo

To get the React Native target, you will install from npm:

npm install --save-dev happo-target-react-native

This guide is assuming you also have the relevant emulators or simulators installed on your machine that you would normally need in order to develop on the corresponding platform.

Defining examples

Happo expects you to have a happo.js entry file at the root that your packager is running.

The entry file should import the client library and define "Stories"

import StoryManager from 'happo-target-react-native/client';

import React from 'react';
import FancyButton from './path/to/components/FancyButton';

StoryManager.make('some example', () => (
  <FancyButton>
    Example Button!
  </FancyButton>
));

Example configuration

// .happo.js
// =========

var ReactNativeTarget = require('happo-target-react-native');

module.exports = {
  // ... 

  targets: [
    // ...
    new ReactNativeTarget({
      // an overridable name to identify the target 
      // (useful for running a specific target from the CLI.)
      // (default: 'react-native')
      name: 'iphone-6',

      // One of `['ios','android']`. Determines which platform you want to test.
      platform: 'ios',

      // the os version of the emulator you'd like to run
      platformVersion: '9.3',

      // the name of the emulator you'd like to run
      deviceName: 'iPhone 6',

      // the orientation you'd like the emulator to be in. One of 'portrait' or 'landscape'.
      // (default shown below)
      deviceOrientation: 'portrait',

      // Control the port used for the local websockets server (default shown below)
      port: 5000,

      // The bash command/path that gets executed to run the packager. This can
      // be customized if you have a custom packager commend you want happo to use
      // instead. (default shown below)
      packagerCommand: 'node',

      // the list of args to be passed to the packager (default shown below)
      packagerArgs: [
        require.resolve('react-native/local-cli/cli'),
        'start',
      ],

      // The working directory the packager command should be executed in.
      // (default shown below)
      packagerCwd: process.cwd(),

      // the environment variables to use in the appium process
      // (default shown below)
      packagerEnv: process.env,

      // appium command timeout, in milliseconds
      // (default shown below)
      newCommandTimeout: 1000 * 60 * 5,

      // the working directory for appium to be executed from
      // (default shown below)
      appiumCwd: process.cwd(),

      // the environment variables to use in the appium process
      // (default shown below)
