How to run React-Native Examples?

Question

I can\'t find any instructions on how to install and run one of the other Examples provided in \'https://github.com/facebook/react-native/tree/master/Examples\' such as \'https:

Answer 1

1) Open your terminal and cd to the specific example you want to run cd home/XYZ/react-native-master/Examples/UIExplorer

2) run npm install

3) run npm start

4) Open the example in Xcode and run it from there It should work fine.

PS: It was so simple but a lot of answers mislead me too.

Answer 2

You have to install node.js in your Terminal with

brew install node

ReactNative use Node.js to build the Javascript code inside the project.

Then you need Watchman, a file watcher from Facebook with

brew install watchman

React Native use Watchman to rebuild your code when there's a change in it.

The final thing is to install and run node with a Terminal window in the react-native folder.

npm install
npm start

Now you can open a project from the react-native/Examples folder in Xcode, then build and run it.

Answer 3

Just wanted to update this for people just trying to run an existing react-native project/app like me:

In Terminal:

1. npm install
2. npm start (should open a separate window to run react package manager or it may use the existing terminal window, if that is the case you will need to open a new terminal window to type the command for step 3)
3. react-native run-ios/react-native run-android

**you may want to run npm update -g (while in the react native folder) to ensure all the npm packages are up to date before running npm install
