ReactNative Playground

Current ReactNative version: 0.27

Right now there is no easy way to make quick ReactNative experiments. Everytime react-native init runs it installs ReactNative all over again.

This package provides a ReactNative container app (similar to rnplay.org) that you can use to run adhoc experiments without having to create new ReactNative projects.

Versioning Policy

RNPlay's major and minor version numbers track ReactNative's version number.

So rnplay 0.27.x would bundle ReactNative 0.27.x.

Install

``
npm install -g rnplay
`

Running The Packager

In any directory that contains index.ios.js and index.android.js, start the packager:

`
$ rnplay packager
`

Try downloading the JavaScript bundle with curl:

`
$ curl localhost:8081/index.ios.bundle
__DEV__=true;

global.__BUNDLE_START_TIME__=Date.now();
})(typeof global !== 'undefined' ? global : typeof self !== 'undefined' ? self : this);
(function(global) {var
modules=Object.create(null);
var inGuard=false;

function define(id,factory){
modules[id]={
...
`

Note: Port 8081 is hardwired in a few places within ReactNative. Not easy to change, sorry.

Launch RNPlay Container App

You only need to launch the container app once. If you want to do another experiment, navigate to another directory and restart the packager server.

iOS App

Launch the RNPlay App in an iOS simulator:

`


Default to 'iPhone 6 Plus'


$ rnplay ios
`

You can switch to a different simulator

`


Default to 'iPhone 6'


$ rnplay ios 'iPhone 6'
`

List the iOS devices you have:

`
$ xcrun simctl list devices

Android App

Invoke Gradle to build and deploy the app:

`
$ rnplay android
``

You'll need to start an Android device on your own, so Gradle can install the app onto it. Use Genymotion
