Does a killer Billy Joel. Built the world's most advanced ORM for frontend so I can build apps faster. Irony noted, but it *does* work to that effect now.

No progress today
finished client library for #promptgrid
Registering another domain name... 🙂‍↔️
cleaned up event detail page and added the link to the event detail page on the venue website if it exists #happenlist
added cronjob so event crawling happens regularly automatically #happenlist
fixed event crawling bugs, now way more events show up #happenlist
finished streaming json implementation for #promptgrid client lib
ported a bit of my streaming json library that i built for java to js. #promptgrid
Making a client library for #promptgrid. How #promptgrid ties into your program code is core, and I didn't realize this at the start. Other prompt evaluation products are often focussed on the non-technical, but I wanna focus on solo-founders, because I am one, and I feel like I need a product like #promptgrid .
users can set prompts in #promptgrid with ts, but if their code doesn't compile it crashes the whole api 😅. Fixing.
improved crawler on #happenlist, making it actually browse –rather than just visit the main page of– websites of venues. Also made it ignore events on irrelevant locations (as happens when a venue is part of a chain and its website is the website of that chain)
just chilled
was always too lazy to implement a cursor for an endpoint, but i knew it was best, but now with the llm i let it do it of course #happenlist
#happenlist's first version & my first ever app store submission got rejected yesterday based on a design guideline that says it "can also be a website", so today I added distance-to-event (which uses location) and notify-me-at-day-of-event features, plus removing some too-obvious web links from the main overview.
Submitted #happenlist to app store review, my first ios app. Then built a website, happnlist.com
now supporting multiple cities! #happenlist
added city selection and improved date display, filtering and fixed bugs in crawling #happenlist
added times and improved time display to #happenlist
IT WORKS, first list of events on phone screen yaay #happenlist
Built and deployed a new node api today, had to rethink the way I do everything because I did it with Cursor and MCPs. Then started my first iOS app that consumes this API and displays its data. Today was the setup. Tomorrow will be the payoff.
