Enforce explicit return types on methods

[m1212e]

In Nest.js there are a few features to auto generate docs/api specs based on typescript types. For this to work, the controllers (http endpoints in nest.js) must have methods which have an explicit return type.

In eslint, this would be the config:

  overrides: [
    {
      files: '*.controller.ts',
      rules: {
        '@typescript-eslint/explicit-function-return-type': 'error',
      },
    },
  ],

This enforces type annotations in controller classes. Would be very helpful to have this in biome! Thanks for your work!

Thank you @m1212e for your proposal. Please use #3 for proposing new rules :)

Also, someone else proposed it here. Feel free to add more value to the discussion

It would be great if someone could implement it :)

Ahh, thanks, did not find it while searching. Will do!
