X-React Router

A complete routing library for React like react-router, but more than it.

v1.2.0

Supporting params: x-react-router@>=1.2.0 will pass the matched route information as props.params to the matched Route. You could get the route information in the component simply through props.params.

What is params

params is an object which contains all the defined params in Route[path]. see path-to-regexp). For example:

  <Route path="/(profile)/:foo/:bar" component={Profile} />
 
  // then, location = 'http://www.example/profile/john/1'
 
  // So, `x-react-router` will pass a prop named `params` to component `Profile`:
 
  this.props.params = {
    0: 'profile',
    foo: 'john',
    bar: '1' // it is a string, not number
  };

Install

npm install x-react-router

x-react-router@>1.0.0

x-react-router v1.x.x is currently released with the next tag (meaning it will not be marked as latest). You can install it with semver:

npm install x-react-router@next

From now on, x-react-router@next will tranform to x-react-router@latest

x-react-router@<1.0.0

x-react-router@<1.0.0 is deprecated now. And will no longer be in maintenance and upgraded. It is a great recommendation for you to upgrade x-react-router to uppper 1.0.0, or @latest

See Important below.

What it looks like

import { Route, Router, Link } from 'x-react-routing';
 
class Home extends Component {
  render() {
    return (
      <div className={this.props.className}>
        <p>Hello, I am {this.props.location.pathname}.</p>
        {this.props.children}
      </div>
    );
  }
}
 
const routes = (
  <Router prefix="/">
    <Route path="home" component={Home} className="home-1">
      <h1>React Routing</h1>
      <Route component={<h1>Hi, I am react-routing.</h1>} />
      <Link to="/demo">To Demo Page</Link>
    </Route>
    <Route path="home" component={Home} className="home-2">
      <p>Hello, I am another Home.</p>
    </Route>
    <Route path="demo" component="/js/login" />
  </Router>
);
 
ReactDOM.render(routes, document.getElementById('container'));

Important

1. Make sure x-react-router is required only once in your app. Such as put it in CommonsChunkPlugin if using webpack.
2. **!!!!**Starting with v1.0.0, x-react-router will change the mechanisms on Route merging. And INCOMPATIBLE with x-react-router@"<1.0.0". In x-react-router@"<1.0.0", if your lazy-loading(including preloads) Routes will be merged to old one's root. But, in x-react-router@">=1.0.0", the lazy-loading Routes will be INSERTED to where they were loaded. For example:

// Home:
<Router>
  <Route path="/(home)?" component={Home} />
  <Route path="/profile" component={Profile}>
    <Route path="p1" component="/js/profile/p1" />
    <Route path="p2" component="/js/profile/p2" />
  </Route>
  <Route path="/setting" component="/js/setting" />
</Router>
 
// Profile/p1: profile/p1 is lazy-loaded
<Router>
  <Route path="/profile/p1" component={P1} />
  <Route path="/profile/p3" component={P3} />
</Router>
 
// In x-react-router@"<1.0.0", x-react-router will have a such result:
<Router>
  <Route path="/(home)?" component={Home} />
  <Route path="/profile" component={Profile}>
    // <Route path="p1" component="/js/profile/p1" /> // This p1 is deleted
    <Route path="p2" component="/js/profile/p2" />
  </Route>
  <Route path="/setting" component="/js/setting" />
  <Route path="/profile/p1" component={P1} />
  <Route path="/profile/p3" component={P3} />
</Router>
 
// BUT, in x-react-router@">=1.0.0", x-react-router will have a result:
<Router>
  <Route path="/(home)?" component={Home} />
  <Route path="/profile" component={Profile}>
    <Route path="p1" component={P1} /> // the old one is replaced by the new ones
    <Route path="p3" component={P3} />
    <Route path="p2" component="/js/profile/p2" />
  </Route>
  <Route path="/setting" component="/js/setting" />
</Router>

It is great recommend to upgrade x-react-router to >=v1.0.0. I am sure you will feel the x-react-router@next pure than x-react-router@latest

Examples

See x-react-router-demo

TODO:

• Supporting Sub-Routes merging: before v0.7.2, x-react-router only supports merging same Route-tree, if the structures are different, x-react-router will mark them new Routes
• File updating
• Caching the component-list
• Basic Routing
• see react-router
• similar but not all same (such as x-react-router use path-to-regexp)
• Parsing path params: pass the path params defined in path to location so the Routes could get them for more[since v1.2.0]
• Supporting lazy-load
• set component=[STRING]
• load STRING[.js]
• re-render the page
• Supporting self-defined props
• passing the self-defined props to Route
• x-react-router will pass to component(React Component/function) when rendering
• Passing the loaction info to component
• component and the children can get it with props.location
• or from react context
• Nested Routes
• nested Route's component will be rendered as a parent Route's child
• you must explicitly use it by this.props.children (same as react-router)
• Route prefix
• <Router prefix='/prefix'></Router>
• all the children routes will generate the url with this prefix
• Supporting the non-Route children
• pass a valid children(see isValidChildren@lib/RouteUtils.js)
• x-react-router can auto compile it to a valid Route with parent path
• Route without path
• use parent's path
• Route without component
• use the default component[see XComponent@lib/Route.js]
• Default loading
• pass loading as the Route's props
• x-react-router will use it when lazy loading
• Optimizing the Routes merging
• Route preloading: since v0.5.0. Just add preload={true} to Route whose router needs preload. x-react-router will not apply the preloaded router, util the Route[path=url, preload=true] was visited.

P.S. x-react-router supports Route without path or component, but not without both. Route without path and component will be ignored, and so it is with it's children.

Q&A:

Q: Why not extend on react-router?

A: Hehe(呵呵)~

--

Q: What the mode of Route's path?

A: see path-to-regexp

--

Q: What x-react-router does for Route's lazy load?

A: By passing a string component(path of the file contains the Routes' real definitions) to Route, x-react-router will load the file and compile the new routes and olds, then re-render the page. (in the file, you should make sure the new Router run after file being executed)

--

Q: 路由组件链缓存规则

A: 第一次访问的路由，其相应的组件链会被缓存在一个对象中；新路由规则在与旧规则合并时，若碰到旧规则被覆盖，则***相应的路由组件链缓存会被清除***。

--

Q: How can the component get the location info (route info)?

A: x-react-router will pass the location info (including pathname/path, query, hash) as a prop to the component defined in Router. And you can get the info through props.location. See all info by logging the props.locationP.S.: location info does not include host, protocol, port and so on

--

Q: How can I pass some self-defined props to the component when it rendered?

A: Just pass these props to Route, x-react-router will do the next.

--

Q: My routes' pathes have a same prefix, and I want to define it only once. What can I do?

A:<Router prefix="YourPrefix">...</Router>

--

Q: How x-react-router handles the none-Routes?

A: x-react-router will compile them to a valid [Routing] by setting their path same with parent's.

--

Q: How x-react-router handles the Routes without path or component?

A: without path, x-react-router will set the path same with parent's; without component, set default component (see XComponent@lib/Route.js).

--

Q: I want a loading when lazy loading, what can I do?

A: pass the loading prop to the Route.

--

Q: Why cannot the same routes been unified to one [Routing]?

A: Same routes, but can be on different level, have different parents; event same level, they may have different props. Best way is to treat them 'different routes'.

--

Q: I want the x-react-router to match the location/route on query level, or hash level, what can I do?

A: pass the mode prop to Router

--

Q: What are path level, query level and hash level? (In x-react-router, we call them modes)

A: They mean how the location/route matched when rendering a component. For examples:

// location = 'http://examples.com/demo/simple?q=1#hash
// path level
if (`/demo/simple`.exec(Route.path))
  render(Route.component);
 
// query level
if (`/demo/simple?q=1`.exec(Route.path))
  render(Route.component);
 
// hash level
if (`/demo/simple?q=1#hash`.exec(Route.path))
  render(Route.component);

--

Q: How can I get the Route's matching modes? (from v0.4.0)

A: see below: PATH is defaulted

import { RouterModes } from 'x-react-router'
const { PATH, QUERY, HASH } = RouterModes;
 
// then use them like this:
// path level
<Router mode={PATH} {...otherProps}>
  // ... <Routes />
</Router>
 
// query level
<Router mode={QUERY} {...otherProps}>
  // ... <Routes />
</Router>
 
// hash level
<Router mode={HASH} {...otherProps}>
  // ... <Routes />
</Router>

--

Q: How to make some of the Routes preloaded? (from v0.5.0)

A: Just pass a preload prop to Route, and value it true:

<Route path="/demo" component="js/demo" preload={true} />

then, x-react-router will load the component="js/demo" and the Routes will apply once the path="/demo" is visited.
