Webpack-dev-子目录中的服务器-未编译&不热重装 [英] Webpack-dev-server in sub directory - not compiling & no hot reloading

问题描述

我正在尝试在子目录(公共)中运行webpack开发服务器，这样我就可以将Reaction集成到现有站点中。

Repo - minimal-react-webpack-starter

当我使用npm run start从子目录运行它时，热重新加载或编译工作都不起作用，但当我在没有--content-base或devServer.publicPath的情况下从根目录运行它们时，它工作得很好。

文件夹结构-

|- App/
    |- node-modules/
    |- public/
        |- react/
            |- main.js
        |- index.html
    |- shared/
        |- react/
            |- components/
            |- main.js
|- package.json
|- webpack.config.js

index.html包含<script src="react/main.js"></script>

webpack配置-

const path = require('path');

const config = {
    entry: './shared/react/main.js',
    output: {
        publicPath: "public/react",
        path: path.resolve(__dirname, 'public/react'),
        filename: 'main.js',
    },
    module: {
        loaders: [
            { test: /.js$/, loader: 'babel-loader', exclude: /node_modules/ },
            { test: /.jsx$/, loader: 'babel-loader', exclude: /node_modules/ }
        ]
    },
    devServer: {
            inline: true,
             publicPath: "public/",
             contentBase: path.join(__dirname, "public"),
             hot: true,
             port: 8080,
        },

}

pacakge.json-

{
"name": "App",
"version": "1.0.0",
"repository": "Ash-repo",
"description": "App",
"devDependencies": {
  "babel-core": "^6.24.1",
  "babel-loader": "^7.0.0",
  "babel-preset-es2015": "^6.24.1",
  "babel-preset-react": "^6.24.1",
  "path": "^0.12.7",
  "react": "^15.5.4",
  "react-dom": "^15.5.4",
  "webpack": "^2.5.0",
  "webpack-dev-server": "^2.4.5"
},
"scripts": {
  "start": "webpack-dev-server --content-base public/ --hot --progress --colors",
  "watch": "webpack --progress --colors --watch",
  "test": "echo "Error: no test specified" && exit 1"
}
}

我不明白为什么它不能编译或重新加载，我已经将publicPath(在输出和DevServer中)和content-base设置为指向Public。我查看了http://localhost:8080/webpack-dev-server/和http://localhost:8080/，但没有重新加载或编译！

如有任何帮助，不胜感激！👍

推荐答案

webpack配置似乎不正确。如果是子目录，使用下面的webpack配置可以实现热重载。

const path = require('path');
const config = {
    entry: './shared/react/main.js',
    output: {
        publicPath: "public/react",
        path: path.resolve(__dirname, 'public/react'),
        filename: 'main.js',
    },
    module: {
        loaders: [
            { test: /.js$/, loader: 'babel-loader', exclude: /node_modules/ },
            { test: /.jsx$/, loader: 'babel-loader', exclude: /node_modules/ }
        ]
    },
    devServer: {
        inline: true,
        publicPath: "/react/",
        contentBase: path.join(__dirname, "public"),
        hot: true,
        port: 8070
    }
}

devServer.Public Path是这里的重要更改。有关更多信息，请访问webpack的官方文档here
