Is it possible to write plugins adding new rules?

[edumudu]

In ESLint, you can write a plugin to add new rules, which can be very useful. However, I cannot find in the documentation a way to achieve the same functionality with Biome. Is there a method available, or is it planned to be implemented in the future?

[ematipico]

It is planned, but we can't give more information at the moment. We still need to evaluate how to provide such functionality

We use ESLint together with Biome now. It's a bit of a hassle, but not being able to migrate our important custom ESLint rules has been a bit of a blocker so far. Is there a roadmap and ETA?

There is no ETA, but plugin support is being tracked here: #2463
