This example shows how to use Code Splitting with entrypoint dependOn
module.exports = {
entry: {
app: { import: "./app.js", dependOn: ["react-vendors"] },
"react-vendors": ["react", "react-dom", "prop-types"]
},
optimization: {
chunkIds: "named" // To keep filename consistent between different modes (for example building only)
},
stats: {
chunks: true,
chunkRelations: true
}
};import react from "react";
import reactDOM from "react-dom";
import propTypes from "prop-types";
console.log(react, reactDOM, propTypes);(self["webpackChunk"] = self["webpackChunk"] || []).push([["app"],{
