If you want to avoid the "No provider for HostAttributeToken..." error when this parameter is not provided, simply mark it as optional and provide an alternative value:

color: string = inject(new HostAttributeToken('color'), { optional: true }) || 'black';

Cool. I checked it out and it solves the problem I had. Thanks!

Very nice. I will also share mine:

It may seem like a weird JavaScript oddity, but it’s actually a powerful feature!
Imagine your code needs to alert the user when two sensors return different values. If both sensors fail and produce faulty data, leading to NaN, the comparison NaN !== NaN triggers the alert—exactly as intended! 🚨
