Reactjs 使用Web包开发服务器时遇到问题

我正试图开始学习如何使用webpack做出反应，并最终将redux放在那里（很难找到一起学习这三个方面的指南…），无论如何，设置有问题。感谢您的帮助。谢谢

编辑：@FakeRainBrigand的解决方案成功了

我的错误是

webpack.config.js

var webpack = require('webpack');
var path = require('path');

module.exports = {
    devtool: 'inline-source-map',
    entry: [
        'webpack-dev-server/client?http://127.0.0.1:8080/',
        'webpack/hot/only-dev-server',
        './src'
    ],
    output: {
        path: path.join(__dirname, 'public'),
        filename: 'bundle.js'
    },
    resolve: {
        modules: ['node_modules', 'src'],
        extensions: ['.js', '.jsx']
    },
    module: {
        rules: [
        {
            test: /\.jsx?$/,
            exclude: /node_modules/,
            use: ['react-hot-loader', 'babel-loader']
        }
        ]
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin(),
        new webpack.NoEmitOnErrorsPlugin()
    ]
};

index.jsx

import React from 'react';
import { render } from 'react-dom';
import App from './components/app';

render(<App/>, document.getElementById('app'));

我对react和webpack都是新手，所以这可能比我想象的要简单得多。非常感谢您的帮助。

您似乎缺少

.babelrc

文件。您可以，也可以只使用这个并安装依赖项

{
  "plugins": [
    "transform-class-properties",
    "transform-object-rest-spread"
  ],
  "presets": [
    [
      "env",
      {
        "targets": {
          "browsers": [
            "> 1%"
          ]
        }
      }
    ],
    "react"
  ]
}

安装

npm install --save-dev babel-preset-env babel-preset-react babel-plugin-transform-class-properties babel-plugin-transform-object-rest-spread

{
  "plugins": [
    "transform-class-properties",
    "transform-object-rest-spread"
  ],
  "presets": [
    [
      "env",
      {
        "targets": {
          "browsers": [
            "> 1%"
          ]
        }
      }
    ],
    "react"
  ]
}

npm install --save-dev babel-preset-env babel-preset-react babel-plugin-transform-class-properties babel-plugin-transform-object-rest-spread
