a journey into search.

I’ve recently wrapped up the core implementation of a search feature - one that went through many twists and turns. It was a long journey to get to where it stands today, and I’d like to revisit that journey to share some of my learnings (and mistakes)!

creating a dynamic union in TypeScript.

Unfortunately, as the model grows more complex, it becomes increasingly easy to disrupt the key discriminators of the union - and equally becomes a point of contention for vcs conflicts.
