服务器以“text/html”的非 JavaScript MIME 类型响应 - 节点

Question

I'm getting this error while trying to create/import a Client instance to connect to a local DB, (PGADMIN).

import {Client} from '/node_modules/pg/lib/'

Error

My Directory

Last part of my index.html

I've tried many types of urls but I can't get it done. So I'm asking for help.

Also, I've tried: const {Client} = require('pg') , but I get the " Uncaught ReferenceError: require is not defined"

Thanks.

Answer 1

You have two problems here.

1. /node_modules/pg/lib/ is going to resolve to an HTML document listing the files in that directory. You can only import a JS file.
2. Any library that allows you to directly connect to a postgresql database is going to depend on APIs provided by Node.js and which are not available in a browser, so even if you imported the correct URL, it still wouldn't work.

Connect to the database from server-side code and use it to provide the client with a webservice that you can access with Ajax.

Browsers don't have native support for CommonJS modules.
