Disable particular rules for template expressions

[marekdedic]

Description

Hi,
I'd like to disable some rules for template expressions only - typically rules about typescript. Example:

<button onClick={() => {clicked += 1}}>Increment</button> // HERE

<script lang="ts">
function fn() { // HERE
    return 3;
}
</script>

With my current configuration, I get the error Missing return type on function (@typescript-eslint/explicit-function-return-type) on the two lines marked by comments. This is problematic, because I can't use TS in template expressions and therefore I can't add a return type annotation to the first line of my snippet. However, I would still like to have the rule turned on for the second case, where it correctly reports that I forgot to add the return type annotation.

Currently, I found no way of doing this other than manually ignoring all the "false positives" or getting rid of any non-trivial template expressions - I would like to have a way to say to eslint that the rule @typescript-eslint/explicit-function-return-type should be turned off for all template expressions, however it should still check <script /> blocks.

Thank you for posting this issue.
But, I think we've already provided a way to ignore template warnings.

Hi,
thanks for the reply and the pointer - I read the docs but thought this would ignore warnings in all svelte code, not just teplate expressions - maybe I'll submit a PR to make it more obvious :)

However, this does not work for me :( See the repro, run npm run lint:ts:eslint - I would expect one error, but I get two. Is this an issue on my side?

It seems there was a bug. I will fix that.
