eslint rule to check decorator present

[tidou44]

Hello
I have been using until-destroy for a few months and I find this library very useful.
However, sometimes I use untilDestroyed(this) and forget to add the @until-destroy() decorator, which gives a runtime error.
Is there a way (eslint rule for example) to ensure that the decorator is present in all components using until-destroyed(this)?

Nope, this is not possible. There're many ways of using the decorator. It can decorate a directive that is placed in a different file, a component can extend the directive, and untilDestroyed is used within this component. Considering the ESLint rule, that would've given an error (because AST is available only per file), but the usage is actually correct.
