使用express和es6来渲染react和jsx服务器端

我正在尝试连接一个最小的概念验证,以呈现单个React组件服务器端。

当我运行我的应用程序时,出现错误:

SyntaxError: express.js: Unexpected token (10:41)

违规行是:

> 10 |   res.send(ReactDOMServer.renderToString(<Component msg={msg} />));
     |                                          ^

这是我的package.json

{
  "name": "ssrReact",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "scripts": {
    "start": "nodemon express.js --exec babel-node --presets es2015,stage-2"
  },
  "dependencies": {
    "express": "^4.14.1",
    "react": "^15.4.2",
    "react-dom": "^15.4.2"
  },
  "devDependencies": {
    "babel-cli": "^6.22.2",
    "babel-preset-es2015": "^6.22.0",
    "babel-preset-stage-2": "^6.22.0",
    "nodemon": "^1.11.0"
  }
}

这是我的Component.js

import React from 'react';

class Component extends React.Component {
  render() {
    return <h1>Hello, {this.props.msg}</h1>;
  }
}

export default Component;

这是我的express.js

import express from 'express';
import React from 'react';
import ReactDOMServer from 'react-dom/server';
import Component from './Component';

const app = express();

function home (req, res) {
  const msg = req.params.msg || 'Hello';
  res.send(ReactDOMServer.renderToString(<Component msg={msg} />));
}

app.get('/', home);
app.get('/:msg', home);

app.listen(3333);

为了让Express能够提供React组件,我需要更改什么?

感谢您的帮助。

我的两分钱,做:

npm i -D babel-preset-react

将您的运行脚本更改为:

"scripts": {
    "start": "nodemon express.js --exec babel-node --presets es2015,stage-2,react"
  },

要解析 jsx ,您需要安装babel-preset-react
