Should we provide a config that disables some rules from @typescript-eslint/eslint-plugin?

[NullVoxPopuli]

For example, no-use-before-define is often wrong if you define multiple components in the same file.

const Foo = <template><Bar /></template>;
const Bar = <template>hi</template>;

would trigger the error.
But this is totally valid, because component rendering is not eager like const-evaluation normally is.

cc @patricklx, in case you have ideas

example in vanilla:

this? #2107

mmm, this might be different .
But it wil be eager later. Because scope is passes directly, right?

[NullVoxPopuli]

mmm, this might be different .

yeah, that PR adds rules to a config, which I don't think we should do.

I imagine the TS config should end up looking like this:

{
  // this is the exact same as what's in the README
  files: ['**/*.gts'],
  parser: 'ember-eslint-parser',
  plugins: ['ember'],
  extends: [
    'eslint:recommended',
    // hopefully this either adds the rules to the config (so that 2107 isn't needed)
    // or we give up on legacy configs and only recommend flat config
    'plugin:@typescript-eslint/recommended',
    'plugin:ember/recommended',
     // this would detect if @typescript-eslint is present, 
     // and make sure no-use-before-define is turned off
    'plugin:ember/recommended-gts', 
  ],
},

[patricklx]

I think the error is correct though.
it will be compiled to something like

Foo =  precompileTemplate(`...`,  {
  scope: [Bar]
})

[patricklx]

I think it was pretty clear that they will not change plugin:@typescript-eslint/recommended behaviour. (Lets discuss this part in #2107)

[NullVoxPopuli]

it wilz be compiled to something like

nay, it's

scope: () => ({ Bar })

[patricklx]

it wilz be compiled to something like

nay, it's

scope: () => ({ Bar })

hmm, i took another look, you are right:)

But it looks like the rule isn't looking that exactly anyway:
eslint playground

[NullVoxPopuli]

ah! so the eslint rule is wrong!

[patricklx]

I looks like that's actually the behaviour it intended to do:

This rule will warn when it encounters a reference to an identifier that has not yet been declared.

https://eslint.org/docs/latest/rules/no-use-before-define#rule-details

[NullVoxPopuli]

yeah -- but .. it's safe!

[patricklx]

i think this can be closed then? as the rule does work correctly as per its own definition

[NullVoxPopuli]

It works incorrectly for how we need it to tho 🤔
