React Native Router react-native-router-flux Join the chat at https://gitter.im/aksonov/react-native-router-flux Codacy Badge npm version

Router for React Native based on new React Native Navigation API.

Features

  • Define your scene transitions in one central location
  • Use simple syntax to call transitions anywhere in your code (e.g. Actions.login())
  • Eliminates the need to pass navigator objects to your screens
  • (new) Ability to show/hide navigation bar as well as customize it for each scene or even a different state of a scene (Edit/Save navbar for edit mode, for example)
  • Support for managing a tab bar, using react-native-tabs (see demo)
  • Support for nested navigators. For example, each tab can have its own navigator, nested in a root navigator.
  • (new) Ability to add own custom scene renderers for action sheet, native TabBarIOS or anything else, see built-in Modal renderer (to display popups) as example. Feel free to submit PR with custom renderers for ActionSheet, Drawer, etc. Let's make awesome library!
  • (new) Dynamically choose scene to render depending from application state (Switch renderer, useful for authentication)
  • (new) Possibility to use own reducer for navigation state.
  • (new) Add action reset to clear the entire history stack. Prevents going 'back'.
  • (new) Support for different states inside same screen. For example "View My Account" could allow in-place edit of fields and "Save", "Cancel" navigation bar buttons should appear.

Change log

  • 3.22.20 fix more ESLint errors, fix passing leftButtonStyle property for back button
  • 3.22.18 fix some ESLint errors and ignore pop for root scene
  • 3.22.17 allow jump & push together - now you could call Actions.tab2_2() (tab2_2 is next scene after tab2) even if tab2 is not active
  • 3.22.16 simplified syntax for sub-states
  • 3.22.15 introduces support for different states inside the same screen.
  • 3.22.10 simplifies customization of own NavBar. From now you could import built-in NavBar from the component and customize it. You could set it globally to all scenes by setting navBar property for Router component. For all other scenes you may pass rightButton, leftButton for custom buttons or rightTitle & onRight, leftTitle & onLeft for text buttons.

IMPORTANT! Breaking changes comparing with 2.x version:

  • React Native 0.22 is required
  • Router is root container now and should not be nested. For nested scenes you should use Scene element
  • Route became Scene, now unique key attribute is required for each scene (it was name attribute before)
  • Define all your scenes on top-level, not within Router as before (see Example)
  • No Schema element is supported for now (for simplicity), maybe later it could be added
  • No ActionSheet support
  • Custom scene renderers are used instead of 'custom' types (like 'modal'), so 'modal' scenes are pushed as usual, but custom renderer will render them as popup. No dismiss, just usual pop to close such popups.
  • No old navigator.sceneConfig support (instead the component uses React Native NavigationAnimatedView for better transitions)
  • No onPush/onPop/etc handlers because they are not needed now. If navigation state is changed, container will be re-rendered with changed navigationState property, see Modal as Example.
  • No header/footer properties are supported for Scene currently - you may include them into Scene component.

Installation

npm i react-native-router-flux --save

Usage

  1. In top-level index.js, define your scenes using Scene element and pass it to Router:
import {Actions, Scene, Router} from 'react-native-router-flux';

class App extends React.Component {
    render() {
        return <Router>
            <Scene key="root">
                <Scene key="login" component={Login} title="Login"/>
                <Scene key="register" component={Register} title="Register"/>
                <Scene key="home" component={Home}/>
            </Scene>
        </Router>
    }
}

Alternatively you could define all your scenes during compile time and use it later within Router:

const scenes = Actions.create(
            <Scene key="root">
                <Scene key="login" component={Login} title="Login"/>
                <Scene key="register" component={Register} title="Register"/>
                <Scene key="home" component={Home}/>
            </Scene>
);
///
class App extends React.Component {
    render() {
        return <Router scenes={scenes}/>
    }
}
  1. In any app screen:
    • import {Actions} from 'react-native-router-flux'
    • Actions.ACTION_NAME(PARAMS) will call the appropriate action and params will be passed to the scene.
    • Actions.pop() will pop the current screen.
    • Actions.refresh(PARAMS) will update the properties of the current screen.

Available imports

Configuration

Router:
Property Type Default Description
reducer function optional user-defined reducer for scenes, you may want to use it to intercept all actions and put your custom logic
createReducer function function that returns a reducer function for {initialState, scenes} param, you may wrap Reducer(param) with your custom reducer, check Flux usage section below
other props all properties that will be passed to all your scenes
children required (if no scenes property passed) Scene root element
scenes object optional scenes for Router created with Actions.create. This will allow to create all actions BEFORE React processing. If you don't need it you may pass Scene root element as children
getSceneStyle function optional Optionally override the styles for NavigationCard's Animated.View rendering the scene.
Scene:
Property Type Default Description
Basic
key string required Will be used to call screen transition, for example, Actions.name(params). Must be unique.
component React.Component semi-required The Component to be displayed. Not required when defining a nested Scene, see example. If it is defined for 'container' scene, it will be used as custom container renderer
initial bool false Set to true if this is the initial scene
type string 'push' or 'jump' Defines how the new screen is added to the navigator stack. One of push, jump, replace, reset. If parent container is tabbar (tabs=true), jump will be automatically set.
clone bool Scenes marked with clone will be treated as templates and cloned into the current scene's parent when pushed. See example.
Animation

        justifyContent: 'center',
        alignItems: 'center',
        backgroundColor: 'transparent',
    }
});

module.exports = Launch;

Modals

To display a modal use Modal as root renderer, so it will render the first element as normal scene and all others as popups (when they are pushed), see Example for more details.

Redux/Flux

This component doesn't depend on any redux/flux library. It uses new React Native Navigation API and provide own reducer for its navigation state. You may provide your own reducer if needed. To avoid the creation of initial state, you may pass a reducer creator. Also all actions will pass themselves to Redux dispatch method if it is passed (i.e. if Router is connected with Redux)

The following example will dispatch the focus action when a new scene comes into focus. The current scene will be available to components via the props.scene property.

Step 1

First create a reducer for the routing actions that will be dispatched by RNRF.

// reducers/routes.js

const initialState = {
  scene: {},
};

export default function reducer(state = initialState, action = {}) {
  switch (action.type) {
    // focus action is dispatched when a new screen comes into focus
    case "focus":
      return {
        ...state,
        scene: action.scene,
      };

    // ...other actions

    default:
      return state;
  }
}
Step 2

Combine this reducer with the rest of the reducers from your app.

// reducers/index.js

import { combineReducers } from 'redux';
import routes from './routes';
// ... other reducers

export default combineReducers({
  routes,
  // ... other reducers
});
Step 3

Create your store, wrap your routes with the redux Provider component and connect your Router

// app.js

import { Router } from 'react-native-router-flux';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware, compose } from 'redux';
import { connect } from 'react-redux';

const RouterWithRedux = connect()(Router);
import reducers from './reducers';
// other imports...

// create store...
const middleware = [/* ...your middleware (i.e. thunk) */];
const store = compose(
  applyMiddleware(...middleware)
)(createStore)(reducers);


class App extends React.Component {
  render () {
    return (
      <Provider store={store}>
        <RouterWithRedux>
            // your scenes here
        </RouterWithRedux>
      </Provider>
    );
  }
}

export default App;
Step 4

Now you can access the current scene from any connected component.

// components/MyComponent.js
import React, { PropTypes, Text } from 'react-native';
import { connect } from 'react-redux';

class MyComponent extends React.Component {
  static propTypes = {
    routes: PropTypes.object,
  };

  render () {
    return (
      <Text>
        The current scene is titled {this.props.routes.scene.title}.
      </Text>
    );
  }
}

export default connect(({routes}) => ({routes}))(MyComponent);

Tabbar

Every tab has its own navigation bar. However, if you do not set its parent <Scene tabs={true} /> with hideNavBar={true}, the tabs' navigation bar will be overrided by their parent.

Custom nav bar for individual scene or even different state of scene (new feature):

Your scene component class could implement static renderNavigationBar(props) method that could return different navbar depending from component props

Switch (new feature)

New feature for 3.x release is custom scene renderer that should be used together with tabs={true} property. It allows to select tab scene to show depending from app state. It could be useful for authentication, restricted scenes, etc. Usually you should wrap Switch with redux connect to pass application state to it: Following example chooses scene depending from sessionID using Redux:

<Scene key="root" component={connect(state=>({profile:state.profile}))(Switch)} tabs={true}
       selector={props=>props.profile.sessionID ? "main" : "signUp"}>
    <Scene key="signUp" component={SignUp}/>
    <Scene key="main" component={Main}>
</Scene>

Split your scenes to smaller parts if needed

Scenes concept is similar to iOS storyboard where you describe all your app screens in one place. However for some large apps, you may want to split it, like iOS app could have several iOS storyboards for different areas of the app. Luckily, you could easy split Scenes using NodeJS built-in require calls:

            <Router>
                    {require("./scenesForTabBar")}
                    {require("./scenesForAnotherPart")}
            </Router>

scenesForTabBar.js:

import React from 'react-native';
import {Scene} from 'react-native-router-flux';

module.exports = <Scene key="tabbar" tabs={true}>
   // scenes here
</Scene>;

Drawer (side menu) integration

Example of Drawer custom renderer based on react-native-drawer. Note that the build-in NavBar component supports toggling of drawer. The Drawer implementation just needs to have a function: toggle();

import React from 'react-native';
import Drawer from 'react-native-drawer';
import SideMenu from './SideMenu';
import {DefaultRenderer} from 'react-native-router-flux';

export default class extends Component {
    render(){
        const children = this.props.navigationState.children;
        return (
            <Drawer
                ref="navigation"
                type="displace"
                content={<TabView />}
                tapToClose={true}
                openDrawerOffset={0.2}
                panCloseMask={0.2}
                negotiatePan={true}
                tweenHandler={(ratio) => ({
                 main: { opacity:Math.max(0.54,1-ratio) }
            })}>
                <DefaultRenderer navigationState={children[0]} />
            </Drawer>
        );
    }
}

/// then wrap your tabs scene with Drawer:
            <Scene key="drawer" component={Drawer}>
                <Scene key="main" tabs={true} >
                        ....
                </Scene>
            </Scene>

Sub-scenes support

You could create 'sub-scene' actions by putting them as children for needed 'base' scene without component prop and call such action anywhere - 'base' Scene will be updated accordingly. Example for 'My Account' screen with edit possibility (MyAccount component should call Actions.editAccount() to enable edit mode and process save, editMode properties accordingly - display edit controls, save data, etc.):

<Scene key="myAccount" component={MyAccount} title="My Account">
    <Scene key="viewAccount" />
    <Scene key="editAccount" editMode rightTitle="Save" onRight={()=>Actions.saveAccount()} leftTitle="Cancel" onLeft={()=>Actions.viewAccount()} />
    <Scene key="saveAccount" save />
</Scene>

Note, that almost empty viewAccount sub-state here is needed to reset MyAccount to initial params defined for this scene (remove save, editMode and other properties from original state) Sure it could be done using Redux, however it will require more coding and programmatic setting NavBar buttons using refresh.
