Webpack and Express - Critical Dependencies Warning
Use webpack-node-externals.
const nodeExternals = require('webpack-node-externals');{ target: 'node', externals: [nodeExternals()],}
Instead of excluding all of the npm dependencies to be bundled with nodeExternals you can also exclude only express by natively requiring it by replacing
import express from 'express';// Orconst express = require('express');To
const express = __non_webpack_require__('express');That will suppress the warning caused by express
