    State-based routing with React components.

    What's included

    can-route-react is a collection of React components that help with routing. The components are modeled after the ones found in React Router. Here's the current list of components:

    • The Route Component - Show or hide components based route data.
    • The Link Component - Create links from route state. (coming soon)

    State-Based Routing

    State-based routing decouples the URL from your application's routing. Routing rules and URLs are created from a state object. It's easier to change URL schemes when needed. The can-route module is arguably the best state-based router available, so it was selected for its core routing functionality.


    Before you can use the components, you'll need to setup can-route. Here's a basic example:

    import route from 'can-route';
    import DefineMap from 'can-define/map/map';
    // Create a DefineMap to setup route attributes.
    const RouteMap = DefineMap.extend({
      '*': {
        serialize: true
      // Define `page` as a string type.
      page: 'string'
    }); = new RouteMap({});
    // Create a '/page' route.
    route('{page}', {page: 'home'});

    The Route Component

    The <Route> component declaratively maps routes to the component hierarchy. It basically shows/hides a component based on the route attributes you provide:

    import {Route} from 'can-route-react';
    // Create a basic Home component.
    Home () { return (<div>Welcome Home!</div>); }
    // The Home component will show when the route has a `page` attribute equal to "home".
    <Route data={{page: 'home'}} component={Home} />

    An alternate syntax allows you to show/hide a component based on the URL path. This is similar to React Router's Route component.

    import {Route} from 'can-route-react';
    // The Home component will show when the URL path is "/" or empty string.
    <Route path='/' component={Home} />

    Pro Tip: While the path syntax works just fine, it's not a recommended practice in state-based routing. It tightly couples your component to the URL. If you change your URL scheme, you have to fix every place that uses that URL.

    Route Example

    import React from 'react';
    import ReactDOM from 'react-dom';
    import {Route} from 'can-route-react';
    // Handlers for the links
    homeClicked () { = 'home';
    aboutClicked () { = 'about';
    // Components to pass into the Route component.
    Home () => {
      return (<div>Welcome Home!'</div>);
    About ({children}) => {
      return (<div>{children}</div>);
      <div className='container'>
          <a href='javascript://' onClick={homeClicked}>Home</a>
          <a href='javascript://' onClick={aboutClicked}>About</a>
                {/* React Router compatible syntax is available. See Pro-tips. */}
          <Route path='/' component={Home} />
          <Route path='/about' component={About} >
            {/* This inner text will show because the About component uses `children`. */}
            Welcome to the About page!

    Running the Demo

    Do npm install or run yarn in the root directory. Start an http-server and open the root directory.


    0.1.0 - The <Route> component can render children if the routed component uses {children} in its content. 0.0.2 - Created the <Route> component.


    npm i can-route-react
