目前,我正在使用express + node.js和webpack作为捆绑程序的后端应用程序。
到目前为止,我能够顺利运行和测试我的代码。
我现在想使用Visual Studio Code调试器来调试我的应用程序。我试图遵循本教程https://medium.com/@jsilvax/debugging-webpack-with-vs-code-b14694db4f8e
现在,当我尝试启动调试器时,它只是打印到控制台Webpack is watching the files…
而不实际运行服务器
这是我的launch.json
文件:
{

"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Launch Webpack",
"program": "${workspaceFolder}/node_modules/webpack/bin/webpack.js",
"args": [
"--config", "./webpack.config.js"
],
}
]
}
这是我的webpack.config.js
文件:
const webpack = require('webpack')
const path = require('path')
const nodeExternals = require('webpack-node-externals')
const StartServerPlugin = require('start-server-webpack-plugin')
module.exports = {
entry: ['webpack/hot/poll?1000', './src/index'],
watch: true,
devtool: 'sourcemap',
target: 'node',
node: {
__filename: true,
__dirname: true
},
externals: [nodeExternals({ whitelist: ['webpack/hot/poll?1000'] })],
module: {
rules: [
{
test: /\.js?$/,
use: [
{
loader: 'babel-loader',
options: {
babelrc: false,
presets: [['env', { modules: false }], 'stage-0'],
plugins: ['transform-regenerator', 'transform-runtime']
}
}
],
exclude: /node_modules/
},
{
test: /\.(graphql|gql)$/,
exclude: /node_modules/,
use: {
loader: 'raw-loader'
}
}
]
},
plugins: [
new StartServerPlugin('server.js'),
new webpack.NamedModulesPlugin(),
new webpack.HotModuleReplacementPlugin(),
new webpack.NoEmitOnErrorsPlugin(),
new webpack.DefinePlugin({
'process.env': { BUILD_TARGET: JSON.stringify('server') }
}),
new webpack.SourceMapDevToolPlugin({
filename: '[name].js.map'
}),
new webpack.BannerPlugin({ banner: 'require("source-map-support").install();', raw: true, entryOnly: false })
],
output: { path: path.join(__dirname, 'dist'), filename: 'server.js' }
};
这也是我的项目结构:
要在不使用调试器的情况下运行此应用程序,我有一个启动脚本,如下所示:
"start": "webpack --colors --progress"
正如我所说的,当我启动调试器时,它只是挂起而没有执行任何操作。我在调试器控制台中收到的唯一消息是Webpack is watching the files…
答案 0 :(得分:0)
我认为您的配置不正确。在“程序”中,从应用程序中选择文件,而不是从Webpack中选择文件,例如“ server.js”或下面的“ index.js”。
{
"type": "node",
"request": "launch",
"name": "Launch Program",
"program": "${workspaceFolder}/index.js"
}
还有其他问题-VSCode中添加了任何断点吗?如果没有,调试器将无法正常工作。
