【问题描述】:
我有一个应用程序正在提供 EJS 视图,我的 React.js 包加载到脚本标记中。
我已按照 react-hot-loader v3 和 @next 的说明进行操作,但都没有工作。控制台中没有错误,并且组件不会在更改时重新渲染。
这是我的应用入口点:
import 'babel-polyfill';
import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import getMuiTheme from 'material-ui/styles/getMuiTheme';
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import injectTapEventPlugin from 'react-tap-event-plugin';
import { AppContainer } from 'react-hot-loader'
import { store } from './routes';
import App from './containers/App';
const render = Component => {
ReactDOM.render(
<Provider store={store}>
<MuiThemeProvider>
<AppContainer>
<Component />
</AppContainer>
</MuiThemeProvider>
</Provider>,
document.getElementById('root'))
};
render(App);
//registerServiceWorker();
// Webpack Hot Module Replacement API
if (module.hot) {
console.log('module.hot exists');
module.hot.accept('./containers/App', () => {
console.log('Reloading app');
render(App);
})
}
这是入口点正在调用的 App 文件:
import React from 'react';
import Navigation from '../components/Navigation';
import { hot } from 'react-hot-loader'
import createRoutes from '../routes';
const routes = createRoutes();
const App = () => {
return ([
<Navigation key="app-navigation" />,
<main style={{ height: 'calc(100% - 85px)' }} key="app-main">{routes}</main>
])
};
export default hot(module)(App)
这是我的 webpack 开发配置:
const devBrowserRender = {
devtool: 'source-map',
context: PATHS.app,
entry: {
app: ['babel-polyfill', 'react-hot-loader/patch',
'./index']
},
node,
devServer: {
contentBase: PATHS.assets,
hot: true
},
output: {
path: PATHS.assets,
filename: '[name].dev.js',
publicPath: PATHS.public
},
module: { rules: rules({ production: false, browser: true }) },
resolve,
plugins: plugins({ production: false })
};
这是我的 JavaScript 规则:
const presets = [["es2015", { "modules": false }], 'react', 'stage-0'];
const plugins = production ? [
'transform-react-remove-prop-types',
'transform-react-constant-elements',
'transform-react-inline-elements'
] : [];
return {
test: /\.js$|\.jsx$/,
loader: 'babel-loader',
options: {
presets,
plugins
},
exclude: PATHS.modules
};
开发者插件:
if (!production) {
return [
new webpack.NamedModulesPlugin(),
new webpack.HotModuleReplacementPlugin(),
new webpack.EnvironmentPlugin(['NODE_ENV']),
new webpack.DefinePlugin(compileTimeConstantForMinification),
new ExtractTextPlugin({
filename: '[contenthash].css',
allChunks: true
}),
// new webpack.optimize.UglifyJsPlugin({ compress }),
new ManifestPlugin({
fileName: 'manifest.json'
})
];
}
我假设这是由于对 react-hot-loader 如何工作的误解造成的,但我在文档或示例中找不到任何其他信息说明它为何不起作用。
