Folks ask us in @typescript-eslint.io about typed linting perf optimizations often. There's a lot of work we *want* to do but can't - so we put our deep explainer in an issue.

Enjoy!

Today I learned that git and github support emojis in branch names. Do with that information what you will.

We've had a few people ask about type-aware linting, eslint's new concurrent linting mode, and why they don't play well together. So we (the ts-eslint team) wrote a short post breaking down why and the design limitations we're constrained by.

TypeScript-ESLint v8.42.0 has been released!

This is our first release with npm provenance!
Shoutout to @jameshenry.bsky.social for the hard work securing our release pipeline.

Been seeing an uptick in what are clearly vibe-coded PRs. On the surface this seems great -- more contributors!

But in the reality it's often AI slop that the person hasn't reviewed and instead the burden of review is on us, the maintainers -- which is a horrible trade.

I asked cursor's AI agent to try to create a small TUI form.
It went HORRIBLY. After a while it declared the task as done despite numerous compiler errors.

When I told it that it wasn't done. This was the agent's response:

Without downloading any new pics what's your energy going into 2025

I've been doing a bunch of work on a meta-linter of sorts and so I need to ingest results from many different linters.

A really painful problem I've discovered recently is that nobody is consistent about how to define a "location" in text. It's a surprisingly complex space to try and reconcile!

I finally started using copilot a few weeks ago. As a skeptic I didn't think that I'd like it so I was surprised to find I actually have found value in it.

(Humble brag) I've met very few people who can pump out code as fast as I can. So I didn't think that copilot would really make me much faster.

The most frustrating thing about providing support to someone is when they use words like "this / that / it".

I tried that, but it errored

Tried what? What error?
Show what you tried!
There's a good chance you did "it" wrong!
After all that's why you're asking for help.

TypeScript-ESLint v8.15.0 has been released!

This release includes:
- a fix for the recent crash introduced with ESLint v9.15.0
- support for arrays in `tseslint.config` (no more spreads necessary!)
- a new rule `no-unsafe-type-assertion`
- and more...!

It's good to know that AI is still a long way off taking my job

I made/maintained a lot of the lint rules people have a love hate relationship with.

"cast"?

Sir it's not a cast unless it's from the native region of programming languages.
Otherwise it's a sparkling assertion.

I want to CREATE something but all of my energy is being used to merely exist right now

Thanks for filing this issue. We generally look at bug reports in order of most-succinct repro to most-complex repro. We have currently scheduled this one for three weeks after the heat death of the universe.

I made an eslint utility that allows finer control over no-restricted-syntax/globals/properties configurations.
In a nutshell it generates a plugin that has one rule per selector -- allowing granular disable comments and better auditing!

👋 Welcome to Bsky, everyone!

I'm jumping on the starter pack bandwagon and making one for the static analysis folks around JavaScript/TypeScript. Projects like ESLint, TypeScript, and new fancy versions of them all.

Who else should go on it?

✨ @brad.zacher.com.au and I are going to hop onto a Twitch stream to talk about typescript-eslint intricacies. We'll deep dive into source parsing, ecosystem compatibility, and all sorts of great nuances. Fun!
