Getting started

just new-typescript-rule <RULE_NAME>

Then register the rule in crates/oxc_linter/src/rules.rs and also declare_all_lint_rules at the bottom.

[Boshen]

Yes! Let's port the recommended list that don't require type information. As a bonus, we should copy over the test suite for extension rules.

@nulladdict Keen to join the fun?

[nulladdict]

Not sure if I have enough rust experience and enough domain knowledge, so I wouldn't count on me :)

No worries

[metreniuk]

@nulladdict @Boshen the @typescript-eslint/prefer-namespace-keyword rule becomes redundant if @typescript-eslint/no-namespace is enabled. Do you think we still need to implement it in case the user wants to disable/configure the rules?

[Boshen]

@typescript-eslint/prefer-namespace-keyword

It's moved to @typescript-eslint/stylistic in v6, so we don't need it anymore.

See https://typescript-eslint.io/rules/prefer-namespace-keyword

[Boshen]

@Thiry1 Thank you, I updated the main list.

[alfaproject]

Will type checking rules be considered for implementation at any point in time?

[Boshen]

Close in favor of #2180 so the creator this issue don't get spammed.
