`react-native-router-flux` is a different API over `react-navigation`. It helps users to define all the routes in one central place and navigate and communicate between different screens in an easy way. But it also means that `react-native-router-flux` inherits all [limitations](https://reactnavigation.org/docs/en/limitations.html) and changes from updated versions.
### IMPORTANT NOTES
#### v5.0.alpha.x is based on React Navigation v5.x (very early alpha, development in progress, help wanted!)
#### v4.2.x is based on [React Navigation v4.x](https://reactnavigation.org/docs/4.x/getting-started)
#### v4.1.0-beta.x is based on [React Navigation v3.x](https://reactnavigation.org/docs/en/3.x/getting-started.html)
#### v4.0.x is based on [React Navigation v2.x]. See [this branch](https://github.com/aksonov/react-native-router-flux/tree/v3) and [docs](https://github.com/aksonov/react-native-router-flux/blob/master/README3.md) for v3 based on deprecated React Native Experimental Navigation API. It is not supported and may not work with latest React Native versions.
#### v4.0.0-beta.x is based on [React Navigation v1.5.x](https://reactnavigation.org/). See [this branch](https://github.com/aksonov/react-native-router-flux/tree/v4.0.0-beta) for this version. It is also not supported and may not work with the latest React Native versions.

## Getting Started
1. Install native dependencies used by RNRF (see below, https://reactnavigation.org/docs/en/getting-started.html)
2. Install this component
```sh
yarn add react-native-router-flux
```
## install the following libraries first
1. react-native-screens by ( ``` npm install react-native-screens || yarn add react-native-screens ```)
2. react-native-gesture-handler ( ``` npm install react-native-gesture-handler || yarn add react-native-gesture-handler ```)
3. react-native-reanimated (``` npm install react-native-reanimated || yarn add react-native-reanimated ```)
4. react-native-safe-area-context (``` npm install react-native-safe-area-context || yarn add react-native-react-native-safe-area-context ```)
5. @react-native-community/masked-view (``` npm install @react-native-community/masked-view || yarn add @react-native-community/masked-view ```)
## Usage
Define all your routes in one React component...
```jsx
const App = () => (
<Router>
<Stack key="root">
<Scene key="login" component={Login} title="Login" />
<Scene key="register" component={Register} title="Register" />
<Scene key="home" component={Home} />
</Stack>
</Router>
);
```
...and navigate from one scene to another scene with a simple and powerful API.
```jsx
// Login.js
// navigate to 'home' as defined in your top-level router
Actions.home(PARAMS);
// go back (i.e. pop the current screen off the nav stack)
Actions.pop();
// refresh the current Scene with the specified props
Actions.refresh({ param1: 'hello', param2: 'world' });
```
## API
For a full listing of the API, [view the API docs](https://github.com/aksonov/react-native-router-flux/blob/master/docs/API.md).
## Try the [example apps](https://github.com/aksonov/react-native-router-flux/tree/master/examples)
```sh
# Get the code
git clone https://github.com/aksonov/react-native-router-flux.git
cd react-native-router-flux/examples/[expo|react-native|redux]
# Installing dependencies
yarn
# Run it
yarn start
```
## v4 Features
- Based on latest [React Navigation](https://reactnavigation.org) API
- Separate navigation logic from presentation. You may now change navigation state directly from your business logic code - stores/reducers/etc. navigationStore
- Built-in state machine (v3 `Switch` replacement)
- Each `Scene` with `component` defined can have `onEnter`/`onExit`/`on` handlers.
- `onEnter`/`on` handler can be async.
- For 'truthy' return of `onEnter`/`on`, `success` handler (if defined) will be executed
- if `success` is a string then router will navigate to the `Scene` with that key
- in case of handler's failure, `failure` prop (if defined) will be run.
- Combining `onEnter`, `onExit`, `success`, and `failure` makes patterns like authentication, data validation, and conditional transitions simple and intuitive.
- [MobX](https://mobx.js.org/)-friendly: all scenes are wrapped with `observer`. You may subscribe to `navigationStore` (`Actions` in v3) and observe current navigation state. Not applicable to Redux.
- Flexible Nav bar customization, currently not allowed by React Navigation:
https://github.com/react-community/react-navigation/issues/779
- Drawer support (provided by React Navigation)
- Inheritance of scene attributes allow you to avoid any code/attribute duplications. Adding `rightTitle` to a scene will apply to all child scenes simultaneously. See example app.
- Access to your app navigations state as simple as `Actions.state`.
- Use `Actions.currentScene` to get name of current scene.
### Helpful tips if you run into some gotchas
## Using Static on Methods with HOCs
- This is just a helpful tip for anyone who use the onExit/onEnter methods as a static method in their Component Class. Please refer to this link https://reactjs.org/docs/higher-order-components.html.
- If your Scene Components are Wrapped in Custom HOCs/ Decorators, then the static onExit/onEnter methods will not work as your Custom HOCs will not copy the static methods over to your Enhanced Component.Use the npm package called hoist-non-react-statics to copy your Component level static methods over to your Enhanced Component.
## Implement onBack from your Scene after declaring it
- If you have a Scene where in you want to make some changes to your Component State when Back button is pressed, then doing this
```jsx
<Scene key={...} component={...} onBack={()=>{/*code*/}}/>
```
will not help.
```jsx
<Scene key={...} component={...} onBack={()=>{/*code*/}} back={true}/>
```
Make sure back = true is passed to your scene, now in your Component's lifecycle add this
```jsx
componentDidMount(){
InteractionManager.runAfterInteractions(()=> {
Actions.refresh({onBack:()=>this.changeSomethingInYourComponent()})
})
}
```
