# rn-host-detect
> Get correctly `localhost` on Android emulator for React Native
On Android emulator, if you want to connect any servers of local, you will need run `adb reverse` on your terminal. This module made it easier, you can get the localhost IP of host machine directly (`10.0.2.2`, Genymotion: `10.0.3.2`).
This was done in the following projects:
* [remote-redux-devtools](https://github.com/zalmoxisus/remote-redux-devtools/blob/fbb169173c235eceb136a02a52c6f36b64297910/src/utils/reactNative.js)
* [reactotron-react-native](https://github.com/infinitered/reactotron/blob/f5de09955b870a90cc772bf6c5139ef8e3ecbbba/packages/reactotron-react-native/src/get-host.js)
That's why you don't need `adb reverse` when you're using these modules on Android emulator.
## Installation
```bash
$ npm i rn-host-detect --save-dev
```
## Usage
```js
const getHostForRN = require('rn-host-detect')
// '10.0.2.2' or '10.0.3.2' on Android
getHostForRN('localhost')
// '192.168.1.111', only convert localhost (or 127.0.0.1) to host IP
getHostForRN('192.168.1.111')
```
