react-router都升级到5.0了,之前用的2.*,想用create-react-app新建个项目用一下
首先是react-router-redux用法变了,使用了ConnectedRouter,本认为毛病在这里,折腾半天发明不是,
ReactDOM.render(
<Provider store={store}>
<ConnectedRouter history={history}>
<App/>
</ConnectedRouter>
</Provider>,
document.getElementById('root')
)
第二官方的code-split计划https://reacttraining.cn/web/…
看文档,不多说,然则,一定会碰到以下报错
Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: null. Check your code at index.js:44.
in Bundle (at index.js:43)
in Abouts (created by Route)
in Route (at index.js:56)
in div (at index.js:54)
in App (at index.js:67)
in Router (created by ConnectedRouter)
in ConnectedRouter (at index.js:66)
in Provider (at index.js:65)
google了半天,
bundle.js里,render要领里,改写
render() {
return this.props.children(this.state.mod)
}
为:
return this.state.mod ? this.props.children(this.state.mod) : null
天下平静了
