react-router4 实现按需加载并利用withRouter传递props

bundle.jsx

import React, {Component} from 'react'

export default class Bundle extends Component {

  componentWillMount() {
    this.load(this.props)
  }

  componentWillReceiveProps(nextProps) {
    if (nextProps.load !== this.props.load) {
      this.load(nextProps)
    }
  }

  load(props) {
    this.setState({mod: null})
    props.load((mod) => {
      this.setState({
        mod: mod.default
          ? mod.default
          : mod
      })
    })
  }

  render() {
    if (!this.state.mod)
      return false
    return this.props.children(this.state.mod)
  }
}
// app.jsx

// bundle模型用来异步加载组件
import Bundle from './bundle.jsx';

// 引入单个页面(包括嵌套的子页面)
// 同步引入
import Index from './app/index.js';
// 异步引入
import ListContainer from 'bundle-loader?lazy&name=app-[List]!../pages/List';

const List = () => (
    <Bundle load={ListContainer}>
        {(List) => <List />}
    </Bundle>
)

// ...

    <HashRouter>
        <Router basename="/">
            <div>
                <Route exact path="/" component={Index} />
                <Route path="/list" component={List} />
            </div>
        </Router>
    </HashRouter>

// ...

webpack.config.js-output
chunkFilename: '[name]-[id].[chunkhash:8].bundle.js'

问题

无法传递this.props,如this.props.params,location
解决


React-router自带的withRouter可轻松解决: import { withRouter } from 'react-router' class Test extends Component { ... render(){ const { match, location, history } = this.props ... } } export default withRouter(Test) //export default withRouter(connect(...)(Test))//with redux

转载于react-router4 实现按需加载并利用withRouter传递props
