#466 (comment)

✅ Stage 1

• refactor: move code into one package #497

We can first colocate js and its implementations inside the same package, but keep them as separate files. For example:

|- packages/eslint-plugin/rules
   |- indent
      | indent-js.ts
      | indent-ts.ts
      | indent.ts
      | indent-js.test.ts
      | indent-ts.test.ts

Where we also have package/eslint-plugin-js/indent/indent.ts re-export from package/eslint-plugin/indent/indent-js.ts

We don't touch the content of those files at all, but only the file structure. This way we can move forward and doing releases without changing the runtime implementation at all.

👉 Stage 2

• test: cross test merged rules (partial) #520
• TODO:

We can then refactor those files under each folder and make sure the ts version passes both js/ts tests. We can start to use the indent-ts to replace the js rules

Stage 3

We merge the implantation of indent-js and indent-ts without touching the tests, where the tests guard us to make sure we don't break the behavior.

Stage 4

Deprecate sub packages, refactoring docs and project structure. Release as v3.0
