Our first React Native implementation is `ReactKit`, targeting iOS. We are also
|
|
working on an Android implementation which we will release later. `ReactKit`
|
|
apps are built using the [React JS](https://github.com/facebook/react) framework, and render directly to
|
|
native UIKit elements using a fully asynchronous architecture. There is no
|
|
browser and no HTML. We have picked what we think is the best set of features
|
|
from these and other technologies to build what we hope to become the best
|
|
product development framework available, with an emphasis on iteration speed,
|
|
developer delight, continuity of technology, and absolutely beautiful and fast
|
|
products with no compromises in quality or capability.
|
|
|
|
## Requirements
|
|
|
|
1. OS X - This repo only contains the iOS implementation right now, and Xcode only runs on Mac.
|
|
2. New to Xcode? [Download it](https://developer.apple.com/xcode/downloads/) from the Mac App Store.
|
|
3. [Homebrew](http://brew.sh/) is the recommended way to install node, watchman, and flow.
|
|
4. New to node or npm? `brew install node`
|
|
5. We recommend installing [watchman](https://facebook.github.io/watchman/docs/install.html), otherwise you might hit a node file watching bug. `brew install watchman`
|
|
6. If you want to use [flow](http://www.flowtype.org), `brew install flow`
|
|
|
|
## Quick start
|
|
|
|
Get up and running with our Movies sample app:
|
|
|
|
1. Once you have the repo cloned and met all the requirements above, start the
|
|
packager that will transform your JS code on-the-fly:
|
|
|
|
```
|
|
npm install
|
|
npm start
|
|
```
|
|
2. Open the `Examples/Movies/Movies.xcodeproj` project in Xcode.
|
|
3. Make sure the target is set to `Movies` and that you have an iOS simulator
|
|
selected to run the app.
|
|
4. Build and run the project with the Xcode run button.
|
|
|
|
You should now see the Movies app running on your iOS simulator.
|
|
Congratulations! You've just successfully run your first React Native app.
|
|
|
|
Now try editing a JavaScript file and viewing your changes. Let's change the
|
|
movie search placeholder text:
|
|
|
|
1. Open the `Examples/Movies/SearchScreen.js` file in your favorite JavaScript
|
|
editor.
|
|
2. Look for the current search placeholder text and change it to "Search for an
|
|
awesome movie...".
|
|
3. Hit cmd+R ([twice](http://openradar.appspot.com/19613391)) in your iOS simulator to reload the app and see your change.
|
|
If you don't immediately see your changes, try restarting your app within Xcode.
|
|
|
|
Feel free to browse the Movies sample files and customize various properties to
|
|
get familiar with the codebase and React Native.
|
|
|
|
Also check out the UI Component Explorer for more sample code:
|
|
`Examples/UIExplorer/UIExplorer.xcodeproj`. **Make sure to close the Movies
|
|
project first - Xcode will break if you have two projects open that reference
|
|
the same library.**
|
|
|
|
## Troubleshooting
|
|
|
|
+ Xcode will break if you have two examples open at the same time.
|
|
+ If `npm start` fails with log spew like:
|
|
```
|
|
2015-02-02 10:56 node[24294] (FSEvents.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-21)
|
|
```
|
|
then you've hit the node file watching bug - `brew install watchman` should fix the issue.
|
|
+ Jest testing does not yet work on node versions after 0.10.x.
|
|
+ You can verify the packager is working by loading the [bundle](http://localhost:8081/Examples/Movies/MoviesApp.includeRequire.runModule.bundle) in your browser and
|
|
inspecting the contents.
|
|
|
|
Please report any other issues you encounter so we can fix them ASAP.
