我正在尝试使用Parcel Bundler作为React服务端渲染中客户端文件的打包器。
我已经使用了Parcel中间件并将其赋值为我的客户端入口点的位置。
当我启动我的脚本时，它显示Parcel正在打包我的文件，但是我的ReactDOM.hydrate方法从未被调用，并且似乎打包程序根本没有使用该文件。
这是我的server.js文件：
import Bundler from 'parcel-bundler';
import express from 'express';
import { renderer } from './Helpers';
const app = express();
const bundler = new Bundler(__dirname + '/index.js');
app.use(express.static('public'));
app.use(bundler.middleware());
app.get('*', (req, res) => {
const context = {};
const content = renderer(req, context);
if (context.url) return res.redirect(301, context.url);
if (context.notFound) res.status(404);
res.send(content);
});
const listeningPort = 5000;
app.listen(listeningPort, () => {
console.log(`Server is now live on port ${listeningPort}.`);
这是我的index.js文件：
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import { routes as Routes } from './Routes';
const routes = Routes;
if (process.env.NODE_ENV === 'development')
ReactDOM.render(
<BrowserRouter>
{routes}
</BrowserRouter>,
document.querySelector('#root'));
else
ReactDOM.hydrate(
<BrowserRouter>
{routes}
</BrowserRouter>,
document.querySelector('#root'));
这是我的渲染器文件，基本上用于渲染HTML文件：
import React from 'react';
import { renderToString } from 'react-dom/server';
import { StaticRouter } from 'react-router-dom';
import { routes as Routes } from '../Routes';
const routes = Routes;
export default (req, context) => {
const content = renderToString(
<StaticRouter location={req.path} context={context}>
{routes}
</StaticRouter>
);
const lang = "en";
return `
<!DOCTYPE html>
<html lang="${lang}">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

<link href="./public/css/style.css" rel="stylesheet" />
<link href="./public/css/color/default.css" rel="stylesheet" id="color_theme" />
</head>
<body>
<div id="root">${content}</div>
</body>
</html>
`;
};
应用程序在StaticRouter内运行并加载内容，但从未执行Hydrate操作。
