使用动态路由时如何定义反应路由器的 IndexRoute

Question

我有一个root route定义：

const rootRoute = {
    childRoutes: [{
        path: '/',
        component: require('./screens/Container'),
        appGlobalVars: appGlobalVars,
        childRoutes: [
            require('./routes/ListApps'),
            require('./routes/Settings'),
            require('./routes/Profile')
        ]
    }]
};


var runApp = (appGlobalVars) => {
    var routes = (
        <Provider store={store}>
            <Router history={ history } routes={rootRoute} />
        </Provider>
    );

    render(routes, document.getElementById('app'));
};

以及嵌套动态路由的一些设置：

./routes/Settings/index.js:

module.exports = {
    path: 'settings',
    getComponent(nextState, cb) {
        require.ensure([], (require) => {
            cb(null, require('../../screens/AppSettings'))
        })
    },
    getChildRoutes(partialNextState, cb) {
        require.ensure([], (require) => {
            cb(null, [
                require('./General'),
                require('./Users')
            ])
        })
    },
};

/settings 是父组件，它渲染 {this.props.children} react router passes。例如，如果我导航到 /settings/general，我将呈现 settings，这又会呈现 general 作为其子项：

./routes/Settings/General.js

module.exports = {
    path: 'general',
    getComponent(nextState, cb) {
        require.ensure([], (require) => {
            cb(null, require('../../screens/AppSettings/General'))
        })
    }
};

这没问题，但我想做的是定义如果导航到 /settings.

应该呈现的默认子组件 Settings

简而言之：有没有办法在使用动态路由时定义类似IndexRoute的东西？

Answer 1

你应该使用 getIndexRoute - https://github.com/reactjs/react-router/blob/master/docs/API.md#getindexroutepartialnextstate-callback

Answer 2

由于 getIndexRoutes 方法被弃用，我注意到 indexRoute 需要一个对象 { component: SomeCompoent }，这是 getComponent 返回的对象的模式，所以我使用 getComponent 提供 indexRoute 如下：

export default (store) => ({
  path : 'shops',
  childRoutes: [ 
    EditShopRoute(store),
  ],
  component: EntityLayout, // this renders always
  indexRoute: { // this renders only when route matches exactly /shops
    getComponent (nextState, cb) {
     require.ensure([], (require) => {
      const Shops = require('./containers/ShopsContainer').default
      const reducerShop = require('./modules/shops').default
      injectReducer(store, { key: 'shops', reducer: reducerShop })

      cb(null, Shops)

    /* Webpack named bundle   */
  }, 'shops')
  } }

})
