React Native Router

Router for React Native based on exNavigator

Features

• Define your screens ("routes") and animation 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
• Use a Schema to define common properties for a group of screens. For example, you can define a "modal" Schema for screens that animate from the bottom of the screen.
• Ability to show/hide navigation bar (see limitations)
• 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. Transition actions will automatically use the top navigator.

Installation

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

Usage

1. In top-level index.js, define a Router and child Route elements for your screens.
   • If some of your screens have common attributes, consider defining a Schema element to reduce repetition
2. In any app screen:
   • import {Actions} from 'react-native-router-flux'
   • Actions.ACTION_NAME(PARAMS) will call appropriate action and params will be passed to the route

Configuration

Router:

Property	Type	Default	Description
header	object	null	optional header view
footer	object	null	optional footer view (e.g. tab bar)
hideNavBar	bool	false	hides navigation bar for every route

Route:

Property	Type	Default	Description
name	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 Router or child, see example
type	string	optional	Defines how the new screen is added to the navigator stack. One of push, modal,actionSheet,replace, switch, reset. Default is 'push'. replace tells navigator to replace current route with new route. actionSheet shows Action Sheet popup, you must pass callback as callback function, check Example for details. modal type inserts its 'component' after navigator component. It could be used for popup alerts as well for various needed processes before any navigator transitions (like login auth process).``switchis used for tab screens.resetis similar to replace except it unmounts the componets in the navigator stack.modal` component could be dismissed by using Actions.dismiss()
initial	bool	false	Set to true if this is the initial screen
title	string	null	The title to be displayed in the navigation bar
schema	string	optional	Set this property to the name of a previously defined Schema to inherit its properties
wrapRouter	bool	false	If true, the route is automatically nested in its own Router. Useful for modal screens. For type==switch wrapRouter will be true
sceneConfig	Navigator.SceneConfigs	optional	Defines the transition animation.
defaultRoute	string	optional	Defines which route to go to if this route is used as a tab and the tab is clicked on when the tab is already selected
hideNavBar	bool	false	hides navigation bar for this route
hideTabBar	bool	false	hides tab bar for this route (if built-in TabBar component is used as footer for parent Router, check Example)
navigationBarStyle	View style		optional style override for the navigation bar
titleStyle	Text style		optional style override for the title element
renderTitle	Closure		optional closure to render the title element
barButtonIconStyle	Image style		optional style override for icon buttons (e.g. back icon)
leftTitle	string		optional string to display on the left if the previous route does not provide renderBackButton prop. renderBackButton > leftTitle > <previous route's title>
renderLeftButton	Closure		optional closure to render the left title / buttons element
renderBackButton	Closure		optional closure to render back text or button if this route happens to be the previous route
leftButtonStyle	View style		optional style override for the container of left title / buttons
leftButtonTextStyle	Text style		optional style override for the left title element
rightTitle	string		optional string to display on the right. onRight must be provided for this to appear.
renderRightButton	Closure		optional closure to render the right title / buttons element
rightButtonStyle	View style		optional style override for the container of right title / buttons
rightButtonTextStyle	Text style		optional style override for the right title element

Schema:

Property	Type	Default	Description
name	string	required	The name of the schema, to be referenced in the route as schema={"name"}
property	-	-	A Schema can have any property that you want the Route to inherit

Modals

To display a modal use type="modal" for your route components. Modal type inserts its 'component' after navigator component. See the Examples folder for more details.

Note that ReactNativeRouterFlux will not provide animations for modals and you'll need to animate the modal yourself (or use a library)

Sidebar/Drawer support

You can easily configure react-native-router-flux to handle a sidebar/drawer for specific routes:
1. Create a sidebar/drawer component (you can use both react-native-drawer and react-native-side-menu) and pass its router props to its children:

<DrawerLayout>
   {React.Children.map(children, c => React.cloneElement(c, {route: this.props.route}))}
</DrawerLayout>

2. In you router component add the sidebar/drawer and nested routes following this pattern:

<Router>
  <Route name="without-drawer"/>
  <Route name="main">
   <Drawer>
      <Router>
        <Route name="with-drawer-a"/>
        <Route name="with-drawer-b"/>
      </Router>
    </Drawer>
  </Route>
</Router>

Here is a complete example of a working drawer using a common app with:

• A session screen that just checks if the user is already logged-in on startup (SessionScreen)
• An auth screen that handles signin/signup (AuthScreen)
• Many other screens that show the true content of the app, all using the sidebar

SideDrawer.js (I'm using 'react-native-drawer')

import Drawer from 'react-native-drawer'
 
class SideDrawer extends React.Component {
  render() {
    return (
      <Drawer
        type="overlay"
        content={<SideDrawerContent />}
        tapToClose={true}
        openDrawerOffset={0.2} 
        panCloseMask={0.2}
        closedDrawerOffset={-3}
        styles={{ drawer: drawerStyle, main: mainStyle }}
        tweenHandler={(ratio) => ({ main: { opacity: (2 - ratio) / 2 } })}
      >
        {React.Children.map(this.props.children, c => React.cloneElement(c, {
          route: this.props.route
        }))}
      </Drawer>
    )
  }
}

Router.js

const hideNavBar = Platform.OS === 'android'
const paddingTop = Platform.OS === 'android' ? 0 : 8
 
export default class Routes extends React.Component {
  render() {
    return (
      <Router>
        <Schema
          name='boot'
          sceneConfig={Navigator.SceneConfigs.FadeAndroid}
          hideNavBar={true}
          type='replace'
        />
        <Schema
          name='main'
          sceneConfig={Navigator.SceneConfigs.FadeAndroid}
          hideNavBar={hideNavBar}
        />
 
        <Route schema='boot' component={SessionScreen} name='session' initial={true} />
        <Route schema='boot' component={AuthScreen} name='auth' />
 
        <Route name='main' hideNavBar={true} type='reset'>
          <SideDrawer>
            <Router
              sceneStyle={styles.scene}
              navigationBarStyle={styles.navigationBar}
              titleStyle={styles.title}
              barButtonIconStyle={styles.barButtonIcon}
              barButtonTextStyle={styles.barButtonText}
            >
              <Route schema='main' component={PlaceScreen} name='place' title='Places' />
              <Route schema='main' component={PaymentScreen} name='payment' title='Payment' header={Toolbar} />
            </Router>
          </SideDrawer>
        </Route>
 
      </Router>
    )
  }
}

Redux/Flux support

This component is not opinionated and does not depend on any implementation of Flux or Redux, but you can easily connect it to them.

If 'dispatch' prop is passed to the router, it will be called with current route as route, name as route name and all route props, check Example for more details.

Also all route actions can be hooked by adding handlers for Actions.onPush, Actions.onReplace, Actions.onPop in your store(s).

Here is an example of connecting the router and its routes to Redux and creating a component aware of being focused:

1. Connect a <Route> to Redux
Connecting a <Route> to Redux is easy, instead of:

<Route name="register" component={RegisterScreen} title="Register" />

you might write:

<Route name="register" component={connect(selectFnForRegister)(RegisterScreen)} title="Register" />

You can also simply connect the component itself in its own file like you usually do.

2. Connect a <Router> to Redux
If you need to inform Redux of the navigation status (i.e. when you pop a route) just override the <Router> component included in react-native-router-flux with a connected one:

import ReactNativeRouter, { Actions, Router } from 'react-native-router-flux'
const Router = connect()(ReactNativeRouter.Router) 

Now when you use a <Router> it will be connected to the store and will trigger the following actions:

• Actions.BEFORE_ROUTE
• Actions.AFTER_ROUTE
• Actions.AFTER_POP
• Actions.BEFORE_POP
• Actions.AFTER_DISMISS
• Actions.BEFORE_DISMISS

Take a look at this for an example.

3. Catch the interested actions in your reducer
For this example I have a global reducer (where I keep the information needed by all my app) where I set the currentRoute:

case Actions.AFTER_ROUTE:
case Actions.AFTER_POP:
  return state.set('currentRoute', action.name)

Now the reducer will catch every route change and update global.currentRoute with the currently focused route.
You also can do many other interesting things from here, like saving an history of the navigation itself in an array!

4. Update your component on focus
I'm doing it on componentDidUpdate of my component of the route named payment. If global.currentRoute is payment and the previous global.currentRoute was different, than the component has just been focused.

  componentDidUpdate(prevProps) {
    const prevRoute = prevProps.global.currentRoute
    const currentRoute = this.props.global.currentRoute
    if (currentRoute === 'payment' && prevRoute !== currentRoute) {
      this.props.actions.doSomething()
    }
  }

P.S.: Remember to check currentRoute === 'payment', otherwise you'll start doSomething() on every route change!

Limitations

Nested Routers

• If you are using a tab bar where each tab has its own Router, modal screens will have to be presented from the root navigator in order to cover the tab bar. To do this, the modal screen should be defined in the root router, and should have the wrapRouter={true} property as in the example below.

        <Router>
          <Schema name="modal" sceneConfig={Navigator.SceneConfigs.FloatFromBottom}/>
          <Route name="myModal" component={myModal} title="Modal" schema="modal" wrapRouter={true} />
          <Route name="tabbar">
            <Router footer={TabBar}>
              <Route name="tab1" schema="tab" title="Tab 1" component={Tab1}/>
            </Router>
          </Route>
        </Router>
