Real app
In a real application you should do this things too:
- Put any normal node.js module in
externalsconfig- For performance
- Not all node.js modules can be bundled
- Specify
output.libraryTarget: "commonjs2"to default to import by require.
- Use
webpack/hot/signalinstead of polling- Send a signal to the process to trigger the HMR
- Enable SourceMaps and source-map-support for node.js
- Handle the case when a hot update fails, i. e. because of errors or not accepted modules
