Vite Polyfill Issue (Solved by Me)

[lukasdobbbles]

This took me a few hours to solve. The issue is that Vite by default doesn't polyfill. This leads to errors with the util package.

Errors

Uncaught TypeError: Cannot read properties of undefined (reading 'custom')

Solution

npm i util

vite.config.js

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      util: "util/",
    },
  },
  define: {
    "process.env": { NODE_ENV: "development" }, // util expects a process.env
  },
});

Maybe instead of util.inspect you could just use JSON.stringify. Otherwise, this might be helpful to include in the docs or mention this somewhere.
