# react-native-native-env
React Native Native Environment module can provide environment variables from native to js
## Install
You can use [rnpm](https://github.com/rnpm/rnpm) to install native module easily;
```bash
npm install react-native-native-env --save
rnpm link
```
And in Android, you must change the line in MainActivity :
```java
new RCTNativeEnvPackage()
```
to
```java
new RCTNativeEnvPackage(BuildConfig.class)
```
## Usage
In js:
```javascript
import NativeEnv from 'react-native-native-env';
NativeEnv.get("APPLICATION_NAME"); // return application's name
NativeEnv.get("VERSION_NAME");// return application's version name
```
Yeah, we hava defined some native variables. These're:
| Key | Source ( Android ) | Source ( iOS ) |
|-----------------:|------------------------------------|----------------------------|
| APPLICATION_ID | BuildConfig.APPLICATION_ID | CFBundleIdentifier |
| APPLICATION_NAME | PackageManager.getApplicationLabel | CFBundleName |
| VERSION_CODE | BuildConfig.VERSION_CODE | CFBundleVersion |
| VERSION_NAME | BuildConfig.VERSION_NAME | CFBundleShortVersionString |
| DEBUG | BuildConfig.DEBUG | #ifdef DEBUG |
Also, you can add some environment variables before react-native runtime is running.
###For Android
Your can send a Map when you init this Module:
```java
HashMap envs = new HashMap();
envs.put("testInfo", "this is a string");
envs.put("testNumber", 23333);
new RCTNativeEnvPackage(BuildConfig.class, envs);
```
And you can add variables from everywhere before it's inited:
```java
RCTNativeEnv.addEnv(key, value);
RCTNativeEnv.addEnvs(map);
```
###For iOS
Your can just add variables from everywhere before react runtime running.
```c
[LRDRCTNativeEnv addEnv:@"test" value:@"info"];
[LRDRCTNativeEnv addEnvs:@{@"testInfo":@"this is a string",@"testNumber":@23333}];
```
