I've lost too many hours trying to debug an SSR react application (the server side). We're building an app from scratch, and it's a very large project so debug the code is really important.
The webpack config for the server is the following:
const path = require('path');
const merge = require('webpack-merge');
const webpackNodeExternals = require('webpack-node-externals');
const webpack = require('webpack');
const baseConfig = require('./app.webpack.base');
const server = {
name: 'server',
entry: ['./app/server/index.js'],
target: 'node',
mode: 'development',
devtool: 'source-map',
output: {
path: path.resolve(__dirname, 'public/server'),
filename: 'server.js',
libraryTarget: 'commonjs2'
},
module: {
rules: [
{
test: [/\.svg$/, /\.gif$/, /\.jpe?g$/, /\.png$/],
loader: 'file-loader',
exclude: /node_modules/,
options: {
name: 'public/media/[name].[ext]',
publicPath: (url) => url.replace(/public/, ''),
emit: false
}
},
{
test: /\.scss$/,
exclude: /node_modules/,
use: [
{
loader: 'css-loader/locals'
},
{
loader: 'sass-loader'
}
]
}
]
},
plugins: [
new webpack.DefinePlugin({
'SERVER_SIDE': true,
'ENVIRONMENT': JSON.stringify(process.env.NODE_ENV),
}),
new webpack.optimize.LimitChunkCountPlugin({
maxChunks: 1
})
],
externals: [webpackNodeExternals()]
};
module.exports = merge(baseConfig, server);
The baseConfig only adds a loader for js and jsx files:
module: {
rules: [
{
test: [/js$/, /\.jsx?$/],
exclude: /node_modules/,
loader: 'babel-loader'
}
]
},
I can't debug it neither in VSCode nor Chrome.
In VSCode, I get the famous:
Unverified breakpoint, Breakpoints set but not yet bound
I'm running the generated server.js file (after bundled with webpack) with node --inspect flag:
I've tried many launch.json configs, example:
{
"name": "Attach to Process",
"type": "node",
"protocol": "inspector",
"request": "attach",
"port": 9229,
"sourceMaps": true
}
And in Chrome, if I open the DevTools for Chrome, I am able to see the source maps and set breakpoints but they never get hit.
I will be very grateful with you guys if you can give me a hand with this. Any insight or idea is appreciated too.
Thanks.
