Thanks for this video!
I've been working on a Prisma/D1/Hono API for the past while and would absolutely love to see some more content tailored to that.

It would be interesting to see how you tackle some of the issues I've run into when trying to create migrations for Prisma/D1.

How to copy on remote the date from local? With apply? When i execute with --command > file.sql, that tells me to do the same cmd with --remote but unlucky so far, no added rows into my d1

[lucaapa]

I was using Prisma and it was too slow with D1 when I had to do joins, for example some requests took 8 seconds, I changed to Drizzle and all requests take less than 1 second

Loved your video, but the only thing that I’m not able to get my head around. Is what font are you using?

[mystica]

i was looking for something like this, thank you!

[shashydass]

I would love to see an example of setting up a D1 project that uses a test database (for CI/CD and tests), local dev database and remote database. That is essential for real world coding.

[Noumaan_Ahamed]

can i assume kv as a nosql db and d1 as a sql db?

[chillbro]

"I wanna copy & paste as much as possible" hahah :D True

[msnegurski]

would be cool to get deep dive on durable objects

nop, wont go for a future "120k" problem

[irvyn]

why is the audio out of sync with the person speaking?

I tried the Cloudflare D1 for a Pages project and it was great, although I couldn't get around it dx (especially dev), but it works well on production.

I but the KV, please is it similar to something like Redix, and can it be used for a Pages project?
