最終的にケースをクラックするまでに数日かかりました。動作する私のコードは次のとおりです。
Webpack 構成オブジェクト
const clientConfig = {
entry: {
client: [
'react-hot-loader/patch',
'webpack-hot-middleware/client',
'babel-polyfill',
'./src/client/client.js',
],
},
output: {
path: path.resolve(__dirname, './build/public'),
filename: '[name].js',
publicPath: '/',
},
devtool: 'inline-source-map',
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.NoEmitOnErrorsPlugin(),
new webpack.LoaderOptionsPlugin({
debug: true,
}),
new CopyWebpackPlugin([
{ from: './src/assets/fonts', to: 'fonts' },
{ from: './src/assets/images', to: 'images' },
]),
new webpack.EnvironmentPlugin(['GOOGLE_MAP_API_KEY']),
],
module: {
rules: [
{
test: /(\.js|\.jsx)$/,
loader: 'babel-loader',
exclude: /node_modules/,
options: {
presets: [['es2015', { loose: true }], 'react', 'stage-2'],
},
},
{
test: /\.scss$/,
use: [
'style-loader',
'css-loader',
'sass-loader',
],
},
],
},
};
サーバー index.js
私はあなたと同じ開発ミドルウェアとホットミドルウェアの両方を使用しています。AppContainerまた、react-hot-loader からインポートし、コンポーネントをラップしています。
import express from 'express';
import React from 'react';
import routes from 'components/Routes';
import html from './html';
import { renderToString } from 'react-dom/server';
import { match, RouterContext } from 'react-router';
import { Provider } from 'react-redux';
import makeStore from 'store';
import Immutable from 'immutable';
import setupNameless from './setupNameless';
import db from './database';
import { actions } from '../client/constants';
import webpack from 'webpack';
import webpackHotMiddleware from 'webpack-hot-middleware';
import webpackDevMiddleware from 'webpack-dev-middleware';
import { clientConfig as wpConfig } from '../../webpack.config.js';
import { AppContainer } from 'react-hot-loader';
import dotenv from 'dotenv';
dotenv.config();
const compiler = webpack(wpConfig);
db();
const app = express();
app.use(webpackDevMiddleware(compiler, {
publicPath: wpConfig.output.publicPath,
// noInfo: true,
stats: {
colors: true,
},
}));
app.use(webpackHotMiddleware(compiler));
app.use(express.static('build/public'));
const { commander: nameless, apiPrefix } = setupNameless(app);
app.use((req, res, next) => {
// make DB call here to fetch jobs.
nameless.exec('jobs', actions.GET_JOBS).then((jobs) => {
const store = makeStore(Immutable.fromJS({
// filters: {},
app: {
apiPrefix,
search: {
query: '',
options: {},
},
},
jobs,
}));
match({
routes,
location: req.originalUrl,
}, (error, redirectLocation, renderProps) => {
if (error) {
res.status(500).send(error.message);
} else if (redirectLocation) {
res.redirect(302, redirectLocation.pathname + redirectLocation.search);
} else if (renderProps) {
// You can also check renderProps.components or renderProps.routes for
// your "not found" component or route respectively, and send a 404 as
// below, if you're using a catch-all route.
try {
res.status(200).send(html(renderToString(
<AppContainer>
<Provider store={store}>
<RouterContext {...renderProps} />
</Provider>
</AppContainer>
), store.getState()));
} catch (err) {
next(err);
}
} else {
res.status(404).send('Not found');
}
});
}, (e) => {
next(e);
}).catch(e => {
next(e);
});
});
app.use(logErrors);
function logErrors(err, req, res, next) {
console.error(err.stack);
next(err);
}
app.listen(process.env.PORT || 3000, () => {
console.log(`App listening on port ${process.env.PORT || 3000}`);
});
クライアント.js
これがそれを機能させる魔法でした。if (module.hot)コードを追加し、AppContainerreact-hot-loader からインポートする必要がありました。もう 1 つの重要な側面はkey={Math.random()}、<Router />コンポーネントに追加することでした。
import { match, Router, browserHistory as history } from 'react-router';
import routes from './components/Routes';
import ReactDOM from 'react-dom';
import React from 'react';
import { Provider } from 'react-redux';
import makeStore from './store';
import Immutable from 'immutable';
import createLogger from 'redux-logger';
import createSagaMiddleware from 'redux-saga';
import sagas from './sagas';
import { AppContainer } from 'react-hot-loader';
const logger = createLogger();
const sagaMiddleware = createSagaMiddleware();
const store = makeStore(
Immutable.fromJS(window.__INITIAL_STATE__),
logger,
sagaMiddleware
);
sagaMiddleware.run(sagas);
ReactDOM.render(
<AppContainer>
<Provider store={store}>
<Router history={history} routes={routes} />
</Provider>
</AppContainer>,
document.getElementById('app'));
if (module.hot) {
module.hot.accept('./components/Routes', () => {
const nextRoutes = require('./components/Routes').default;
ReactDOM.render(
<AppContainer>
<Provider store={store}>
<Router key={Math.random()} history={history} routes={nextRoutes} />
</Provider>
</AppContainer>,
document.getElementById('app'));
});
}
幸運を
