I've completed Day Twenty Two - Advent of TypeScript 2023 typehero.dev/challenge/day-2… #AdventOfTypescript Tests were passing with just checking rows for validity so called it there. Didn't fancy spending another 3 hours on it like yesterday 😅. Solution in follow up

I've completed Day Twenty One - Advent of TypeScript 2023 typehero.dev/challenge/day-2… #AdventOfTypescript Wow that was rough. Another one where I'm not willing to touch the code anymore.

I've completed Day Twenty - Advent of TypeScript 2023 typehero.dev/challenge/day-2… #AdventOfTypescript Possibly the ugliest code, but at this point I'm just happy they're still getting done

📢 Bonus for day 12 of #AdventOfTypescript 1⃣ No recursion, using the fact that Tuples are actually Objects 2⃣ Remapping Objects is essentially a 'For' loop 3⃣ Simpler solution coming later Credits : @BanJoeH and @mattpocockuk

Why are we calling islands "islands" when they are being hydrated? shouldn't we call them "oasis" and the rest of the web page as "desert"?

Bringing database and backend work into a single TypeScript file is just as beneficial as developing a full-stack application in one language Some thoughts on that 🧵

Have you ever heard of adding a "redundant condition" to your query? A condition that doesn't change the results at all? It seems like that would be totally useless, but it can actually be a trick to unlock your indexes!  planetscale.com/blog/redunda…

A lot of requests we receive about @DrizzleOrm are related to the "convenience" APIs - stuff that is present in a lot of popular ORMs and that, for a lot of people, differentiates "ORMs" from "query builders". Let me share our vision of it and a bit of Drizzle history.

I'm trying to create a custom useQuery hook that allows for consumers to add their own options, omitting a couple. Here's a TS playground of the error I'm having typescriptlang.org/play?#cod… any ideas? @tan_stack

Hi @MiroHQ I'm trying to log into my account and I get an infinite loading screen and errors in the console

How i can get correct data typing from @tan_stack query (v3 😬) that returns either an array or a single item from that array based on an optional arg? or is it better to separate it into its own hook? cc @TkDodo ts-playground: shorturl.at/mFJ29
