Node.js - 要求未定义

Question

I'm trying to import the mysql driver in node.js but I keep getting this error:

Uncaught ReferenceError: require is not defined

This is the line that is causing the issue:

//database.js
const mysql = require("mysql");

The file that is causing the issue is called database.js which I am trying to import into script.js using

//script.js
import {myFunction} from "../database.js";

This is how I am importing script.js in HTML:

<script type="module" src="script.js"></script>

I'm using Node.js 12.18.0

Answer 1

You cant use CommonJs (require) in the browser, it is for Node.js.

You cant, or should not be able to use mysql stuff on the client side, this would be a big security issue.
