What changes did you make? (Give an overview)
tsx
instead ofjiti
Support loading
eslint.config.ts
eslint.config.mts
eslint.config.cts
files powered bytsx
. The support is opt-in by users, where they need to installtsx
explicitly (we include it as optional peer deps instead ofdependencies
)Based on my previous experiments with
eslint-ts-patch
(which supports swapping different loaders likejiti
tsx
bundle-require
, feel free to try them out). So for I see thattsx
is the best approach as it uses Node's native loader API, support full ESM, top-level await, and does not generate temporary files.The only downside is that it uses Node's API, which has only been available since
v20.8.0
andv18.19.0
. But considering this is an opt-in feature, it should be fine, and the ecosystem should catch up soon.Is there anything you'd like reviewers to focus on?
