I would appreciate a TypeScript LSP MCP, Claude Code could turn a laborious non-deterministic process (easily 1+ minutes on large code bases) of identifier renames into a few seconds deterministic process. For now I try to do that for Claude but steals some degree of flow from me.

TIL! How subtle is that, damn. Seems like a good candidate for a lint rule.
learned something new in #TypeScript today. an arrow function is only analyzed as a never-returning call if it has an explicit annotation on the variable name (distinct from a return type on the arrow function)

I've been making big strides with Graffle the past couple weeks, such as around the static builder and support for variables, docs, and type level string parser. Accordingly I revamped docs to cover everything one should need to know about these features. Here's a rundown:

So last month I gave two talks at GraphQL Conf in Amsterdam and it was a lot of fun and challenge for me but unfortunately a glitch means my talk on Polen (polen.js.org) will never see the light of day, though my shorter talk on Graffle (graffle.js.org) will.
