# react-native-launch-darkly
3+
4+
React Native wrapper over LaunchDarkly SDK's for iOS and Android.
5+
6+
[LaunchDarkly](https://launchdarkly.com)
7+
8+
[Native iOS SDK](https://github.com/launchdarkly/ios-client)
9+
10+
[Native Android SDK](https://github.com/launchdarkly/android-client)
11+
12+
## Getting started
13+
14+
`$ npm install react-native-launch-darkly --save`
15+
16+
or
17+
18+
``$ yarn add react-native-launch-darkly --save``
19+
20+
### Mostly automatic installation
21+
22+
`$ react-native link react-native-launch-darkly`
23+
24+
#### iOS:
25+
26+
1) In XCode in project navigator right click on application name => Add files to... => navigate to node_modules/react-native-launch-darkly/ios and select Darkly.framework.
27+
2) Go to you project target and add Darkly.framework to Embedded Binaries
28+
29+
#### Android:
30+
31+
Add line bellow at the bottom of your app/build.gradle
32+
```
33+
configurations.all { resolutionStrategy.force 'com.squareup.okhttp3:okhttp:3.4.1' }
34+
```
35+
36+
### Manual installation
37+
38+
39+
#### iOS
40+
41+
1. In XCode, in the project navigator, right click `Libraries` ➜ `Add Files to [your project's name]`
42+
2. Go to `node_modules` ➜ `react-native-launch-darkly` and add `RNLaunchDarkly.xcodeproj`
43+
3. In XCode, in the project navigator, select your project. Add `libRNLaunchDarkly.a` to your project's `Build Phases` ➜ `Link Binary With Libraries`
44+
4. Run your project (`Cmd+R`)<
45+
46+
#### Android
47+
48+
1. Open up `android/app/src/main/java/[...]/MainActivity.java`
49+
- Add `import com.reactlibrary.RNLaunchDarklyPackage;` to the imports at the top of the file
50+
- Add `new RNLaunchDarklyPackage()` to the list returned by the `getPackages()` method
51+
2. Append the following lines to `android/settings.gradle`:
52+
```
53+
include ':react-native-launch-darkly'
54+
project(':react-native-launch-darkly').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-launch-darkly/android')
55+
```
56+
3. Insert the following lines inside the dependencies block in `android/app/build.gradle`:
57+
```
58+
compile project(':react-native-launch-darkly')
59+
```
60+
4. Add line bellow at the bottom of your app/build.gradle
61+
```
62+
configurations.all { resolutionStrategy.force 'com.squareup.okhttp3:okhttp:3.4.1' }
63+
```
64+
65+
66+
## Usage
67+
```javascript
68+
import LaunchDarkly from 'react-native-launch-darkly';
69+
70+
type User = {
71+
key: string,
72+
email?: string,
73+
firstName?: string,
74+
lastName?: string,
75+
isAnonymous?: bool
76+
};
77+
78+
// init native SDK with api key and user object
79+
LaunchDarkly.configure(apiKey: string, user: User);
80+
81+
// get feature flag value
82+
LaunchDarkly.boolVariation(featureFlagName: string, callback: function): bool
83+
84+
// adds listener which is called every time feature flag value is changed
85+
LaunchDarkly.addFeatureFlagChangeListener(callback: function): void
86+
87+
// removes onFeatureFlagChange listener
88+
LaunchDarkly.addFeatureFlagChangeListener(): void
89+
```
