I used Cursor to generate the JS SDK from the OpenAPI v3 spec. It took less than an hour, and after some polishing and testing, everything works well in the browser, Node, and React 🚀 Types included🔥 For those interested, I leave the Github repo in the comment✌️

How NOT to build a successful product?
Implement Payment Gateway integration before getting the first customers wanting to pay for it.
I've integrated Paddle about 3 times in my projects, but never got a paying customer 🥲😅

I'm thinking about going one step forward in #buildinpublic and combining it with #opensource
I need to clean up lots of "wip" commits from git history before going fully #buildopensource 😂
But I will do it.

The possibility to continue via google, github, classic email/pass, and a magic link seems a must-have to not lose too many potential signups in 2025 😄

Today I've worked on alert snoozing.
On the DB side, I've added two nullable columns in the alert table:
- snooze_until (timestamp)
- snooze_forever (bool)
Adding two columns is better because data have better integrity and avoid weird checks like if date > 2099

Is classic email/pass login methods still relevant for saas in 2025?
How about only „continue with google” and github?

Is #tailwind -ui worth it? Most important for me is having consistent styling between Astro and Remix.

How did the migration from #influxdb to #timescaledb go:
- timescale setup on existing PostgreSQL instance took me 5min (good docs),
- LLMs partly helped in query rewrite and partly suggested trash - it is how it is,
I hope I won't regret this migration later on 😅 🤞

As a member of #boringtechnologyclub, I've chosen Postgres as the general database.
I've also chosen #influxdb as timeseries db (error metrics) instead of #timescaledb because I'm unfamiliar with it.. but it looks like good old SQL 🩶
I'm thinking about giving it a try.
