Can you recommend a mysql driver for deno that isn't a complete dead end?

mysql2 port: never updated. mysql driver: doesn't support strings mysql connector from Oracle: no one cares to port to Deno. ALL, I mean ALL I can think about is going back to superb PHP PDO. What a challenge...

Have you seen https://docs.deno.com/runtime/tutorials/how_to_with_npm/mysql2 ?

Did you ever end up finding anything @Bairdy? I'm trying to get it to work but having issues connecting https://discord.com/channels/684898665143206084/684898665151594506/1187550860746698833

i'm using knex with mysql2 from npm: and it just works

TehShrike•12mo ago

does your server have SSL disabled?

Antonio Sampaio•12mo ago

yep (internal only) maybe its something with the ssl implementation and node compat

TehShrike•12mo ago

Yeah, probably.

Kevin Whinnery•12mo ago

If the mysql2 npm module isn't working, that's definitely a compatibility issue we should jump on - @toninho do deno if you have a reproduction case we could use to validate, that would be awesome

Antonio Sampaio•12mo ago

i guess @TehShrike can help with a reproduction case

TehShrike•12mo ago

yeah, I can try to write up something more thorough, though about half the details are here: https://discord.com/channels/684898665143206084/684898665151594506/1187550860746698833 the rest of the details are: mysql 8.0.35, from the default macOS installer from https://dev.mysql.com/downloads/mysql/ with no my.cnf file. At some point I guess the default mysql settings started requiring TLS Besides passing in (or not) that ssl property to createConnection, I also passed in host, user, database, password Let me know if you want me to try anything else When I try connecting to PlanetScale with ssl: { rejectUnauthorized: false }, I get an error with the message "unavailable: unable to connect to branch tcancv32qlrt" and then "Uncaught Error: read UNKNOWN"

Kevin Whinnery•12mo ago

So if I try to connect to a PlanetScale DB with the options you mention using mysql2 on npm, I should probably see what you are seeing

TehShrike•12mo ago

hah, my PlanetScale database was asleep. One moment I am successfully able to connect to PlanetScale with ssl: { rejectUnauthorized: false } I am also able to connect to PS with ssl: { rejectUnauthorized: true } So everything seems cool there. The issue seems to be when connecting to a local database that requires SSL.

Antonio Sampaio•12mo ago

so... are u providing SSL on the local db and the server?

TehShrike•12mo ago

I'm not providing a cert, but I am enabling SSL. When connecting to local:

Kevin Whinnery•12mo ago

Yeah, I feel like now we are in the land of certificate handling, and Deno and Node have different mechanisms of handling SSL handshakes (if indeed Node is able to connect to your local DB)

TehShrike•12mo ago

Yes, I am able to connect to the local db with node. I was also to connect to the local db in Deno using this native Deno library: https://github.com/denodrivers/mysql

Kevin Whinnery•12mo ago

Hm, got it.

TehShrike•12mo ago

Want me to create an issue?
