react-native-uuid-generator

A simple wrapper around the native iOS and Android UUID classes. Exposes a single method, getRandomUUID.

Getting started

$ npm install react-native-uuid-generator --save

$ react-native link react-native-uuid-generator

Usage

This library supports both callback and promise interfaces.

import UUIDGenerator from 'react-native-uuid-generator';
 
// Callback interface
UUIDGenerator.getRandomUUID((uuid) => {
  console.log(uuid);
});
// => "42A8A87A-F71C-446B-B81D-0CD16A709625"
 
// Promise interface
UUIDGenerator.getRandomUUID().then((uuid) => {
  console.log(uuid);
});
// => "BD6120BD-3612-4D56-8957-99F5D6F02C52"

Manual installation

If the react-native link command doesn't work, you can also install the native components of this library manually.

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-uuid-generator and add RNUUIDGenerator.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNUUIDGenerator.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainApplication.java

• Add import io.github.traviskn.rnuuidgenerator.RNUUIDGeneratorPackage; to the imports at the top of the file
• Add new RNUUIDGeneratorPackage() to the list returned by the getPackages() method

1. Append the following lines to android/settings.gradle:

  include ':react-native-uuid-generator'
  project(':react-native-uuid-generator').projectDir = new File(rootProject.projectDir,   '../node_modules/react-native-uuid-generator/android')

1. Insert the following lines inside the dependencies block in android/app/build.gradle:

  compile project(':react-native-uuid-generator')

Upgrading

See the changelog for instructions on upgrading to the latest version.

Example

Check out the example app included in the github repo to see the UUID Generator in action! I assume you already have the react-native-cli installed, as well as the required iOS or Android dependencies.

git clone https://github.com/Traviskn/react-native-uuid-generator.git

cd react-native-uuid-generator/example
npm install

Use react-native run-ios or react-native run-android to run the example.
