(React Native) Razor

Router for React Native with declarative configuration similar to React Router.

• Declarative configuration (using <Route> similar to react-router)
• Idiomatic React; no imperative API or self-contained state (unlike react-router)
• Uses NavigatorExperimental (soon to replace Navigator and NavigatorIOS in core React Native)

Install

npm install rn-razor --save

Usage

Configuration

import {Router, Route, StateUtils} from "rn-razor";
 
class Application extends React.Component {
  state = {
    routerState: StateUtils.create({initialRoute: "index"}),
  };
 
  render() {
    <Router routerState={this.state.routerState}>
      <Route name="index" component={Index} />
      <Route name="profile" component={Profile} />
      <Route name="contacts" component={ContactList} />
      <Route name="contact" component={ContactDetail} />
    </Router>
  }
}

Navigation

import {StateUtils} from "rn-razor";
 
routerState = StateUtils.push(routerState, "profile");
routerState = StateUtils.pop(routerState);
routerState = StateUtils.jumpTo(routerState, "contact", {id: 10});
routerState = StateUtils.resetTo(routerState, "contact", {id: 10});

Reference

<Router>

routerState

The current state of navigation.

Can be initialized to an initial route with StateUtils.create({initialRoute: "..."}).

Example

{
  index: 1,
  routes: [
    { name: "index" },
    { name: "contact-detail", params: { id: 3 } },    
  ]
}

children

A collection of <Route> components providing the declarative configuration.

onWillFocus

Called when a route is about to be rendered or "focused" (name comes from react-native). This is called after the route's onEnter (if present).

onDidFocus

Called when a route has been rendered or "focused". This is called after the route component's componentDidMount (tip: good place to hide a splash screen from rn-splash-screen).

createElement

When the router is ready to render a specific scene, it will use this function to create the elements.

Default

function createElement(Component, props) {
  return <Component {...props} />
}

render

When the router is ready to render the scene stack, it will use this function.

Use this callback to add persistent views around the scene stack. Perhaps a navigation drawer or wrap scenes in KeyboardAvoidingView from react-native.

Default

function render(scenes) {
  return scenes;
}

<Route>

name

The route key to use as a unique index during navigation.

component

The component to be rendered for the route.

onEnter

Called when a route is about to be entered.

onLeave

Called when a route is about to be exited. Called before the next route's onEnter.

children

A collection of <Route> components that are treated as a group, invoking their parent's onEnter and onLeave as a group.

For instance, a group of routes can be given a single onLeave or onEnter that is called when the router is no longer in the group or when entering the group for the first time.

Note that a <Route> cannot have both a component and children as component nesting is not currently supported.
