= feature-react-navigation - Feature based navigation using react-navigation

feature-react-navigation is a https://feature-u.js.org/[feature-u] module which provide a routing aspect into your features using https://reactnavigation.org/[react-navigation].

The module aim to build a single navigation tree with routes provided by each feature registred in your feature-u instance. Your features don't have the knowledge off the final tree, they only have to expose their routes throught the route aspect.

== Getting started

$ yarn add feature-react-navigation

Additionnally, you may need peerDependencies installed :

[source,bash]

$ yarn add feature-u $ yarn add @react-navigation/core $ yarn add @react-navigation/native or $ yarn add @react-navigation/web

== Usage

=== 1 - Register the aspect

Within your mainline, register the feature-react-navigation routeAspect to feature-u's https://feature-u.js.org/cur/api.html#launchApp[launchApp()] method.

Please note that routeAspect has 1 required named parameter (see below for details) :

• <<Navigator configuration,Navigator>>

==== App.js

[source,js]

import { launchApp } from 'feature-u'; import { createRouteAspect } from 'feature-react-navigation'; import { createAppContainer } from '@react-navigation/native'; import features from './feature';

// configure Aspects (as needed) const routeAspect = createRouteAspect({ Navigator });

export default launchApp({

aspects: [ routeAspect, ... other Aspects here ],

features,

registerRootAppElm(rootAppElm) { AppRegistry.registerComponent(appName, () => () => rootAppElm); // convert rootAppElm to a React Component }, });

==== Navigator object configuration

This is the classic

With this configuration, the module stay a pure react module. Any adherence with react-native is no longer required.

==== navigationPattern configuration

In mobile application, the navigation stack could be a lot more complex than on the web and react-navigation respond to that complexity by providing some different navigators (https://reactnavigation.org/docs/en/stack-navigator.html[stack], https://reactnavigation.org/docs/en/switch-navigator.html[switch], https://reactnavigation.org/docs/en/bottom-tab-navigator.html[tab], https://reactnavigation.org/docs/en/drawer-navigator.html[drawer]). The navigationPattern configuration is the way to deal with it in feature-react-navigation.

Beside, features don't have to know how the navigation is organize in the final application. Even, you may want to re-use some feature across applications whithout inheriting the same navigation stack. With this way of building navigation stack, your application have total control about it.

• navigator: create[Navigator] function
• navigationOptions: options taken by the navigator function
• routes: list of named route from features
• featureRoutes: list of feature names, expended to each routes starting by the feature name - see <>.

[source,javascript]

const Navigator = ({ routes }) => { return ( <Stack.Navigator> {routes.map(route => <Stack.Screen name={route.screen.name} component={route.screen} />)} </Stack.Navigator> ) }

2 - Promote routes

Within each feature that promotes UI Screens, simply register the feature's route through the Feature.route property (using feature-u's [createFeature()]).

In the sample, login feature promotes somes routes in a react-navigation compatible format. It's strongly encouraged to prefix all route names by the feature name in order to use <<featureRoutes>> pattern configuration.

.src/feature/login/index.js [source,javascript]

import React from 'react'; import {createFeature} from 'feature-u';

import fname from './feature-name' import {LoginScreen, LoginSuccessScreen} from './screens';

export default createFeature({

name: 'login',

route: { routes: { [${fname}.LOGIN]: { screen: LoginScreen, }, [${fname}.SUCCESS]: { screen: LoginSuccessScreen, }, }, },

... snip snip });
