I have a simple example of Lit code that looks like this:
import { property } from 'lit/decorators.js';
export class MyClass extends LitElement {
@property()
rows = [];
}
Even though my code renders correctly and works with existing data, TypeScript gives me an error saying property is not being used. Could there be something missing in my TS setup related to decorators? I created the project using the OWC tool.
It appears that Open WC is outdated as it installs typescript lint version 4.33.0 instead of the required 5.*
If you are facing a similar issue, check out this solution: Eslint wrong error `is defined but never used` warning in NestJs for all decorators
To resolve this, make sure to update your package.json with the following:
"@typescript-eslint/eslint-plugin": "^5.48.0",
"@typescript-eslint/parser": "^5.48.0",
After restarting my ESLint server in VS Code, everything started working smoothly.
I quickly reported the issue and it was promptly fixed at https://github.com/open-wc/open-wc/issues/2557.
I'm leaving this question here for future reference.
