Use an input of map<string,string> when passing to an angular component

Trying to pass an input value for a component reuse, but facing the challenge of having to use a "hardcoded" map of strings. Uncertain about how to effectively pass this information:

<continue-p
  [additionalInfo]="{ "myString": "string", "myNumber": "4" }">
  <p>
    Paragraph
  </p>
</continue-p>

The input field is structured like this:

@Input()
  additionalInfo?: Map<string, string>;

Any recommendations for a better way to handle passing such data to components would be greatly appreciated.

Answer №1

Maps have their distinct type Map<K, V>, setting them apart from regular objects. If you're working with a plain object, consider using Record<K, V>.

Record<string, string> is useful for representing an object with keys and values both being strings, denoted as { [key: string]; string] }.

To make the switch in your code, simply replace instances of Map with Record:

additionalInfo?: Record<string, string>;
