Input stuck when use mask + empty custom patterns

[Bad-Company]

I'm trying to build a generic input component, where custom patterns are optional. However, if I pass an empty object, my input gets stuck. I also can't set patterns=undefined because TS will throw a type mismatch error. Currently, I just copied the library patterns and set them as a default.
Are there any better solutions?

<input
      [mask]="options.mask"
      [patterns]="options.customPatterns ?? {}"
/>

@Bad-Company passing an empty object wouldn't work because the library directive relies on some initial patterns

Instead of using {} as fallback, try to use initialConfig.patterns

<input
      [mask]="options.mask"
      [patterns]="options.customPatterns ?? initialConfig.patterns"
/>

import { initialConfig } from 'ngx-mask';

...

protected readonly initialConfig = initialConfig;
