Help! Getting ‘getaddrinfo ENOTFOUND’ Error When Connecting to MySQL

It sounds like your hostname isn’t resolving correctly. The 'ENOTFOUND' error means Node.js can’t find your database server where you’ve pointed it. Just double-check the hostname or IP you’re using from Digital Ocean; it must be accurate. If DBeaver connects fine, the problem is likely your Node setup. Here’s a snippet to help you troubleshoot:

```javascript
const dns = require('node:dns');
dns.lookup('your-db-host-from-DO', (err) => console.log(err || 'Host resolved!'));
```

If this fails, you might be dealing with network or firewall issues.

First off, check if your hostname can be resolved. Sounds like it’s not working right now. You can run a DNS lookup to see if your server is reachable. Also, make sure you're not accidentally overriding the default settings by sending empty strings in your configuration. It could also help to see what the createConnection function is up to if you dive into the library code. If you’re really stuck, try to just set the full hostname or IP from Digital Ocean instead of using empty strings.

Here's a quick test for internet access:

```javascript
const dns = require('node:dns');
dns.lookup('google.com', (err) => console.log(err || 'node can access the internet'));
```

You definitely need to use the full hostname or IP address that Digital Ocean has provided, rather than leaving those fields blank. If Node can’t locate your database server, that’s going to throw the ENOTFOUND error. Also, it’s great that you used DBeaver successfully, so if Node is failing, it could be related to DNS settings or some firewall issues. Make sure you fill in all the required fields in your connection configuration too.

Another tip: using the mysql2 package is usually recommended over mysql these days; you might want to consider switching if you're still having issues.
