I have put together a dictionary like so:
const iconTypesDictionary: { [key: string]: IconPrefix } = {
solid: 'fas',
regular: 'far',
light: 'fal',
}
My goal is to be able to utilize the keys of this dictionary as potential values for the property. In order to replace the repetitive keys in this scenario:
export interface IconProps {
type?: 'solid' | 'regular' | 'light';
}
Is there a resolution for this?
Until we have the satisfies feature in TypeScript (check out ms/TS#47920 and ms/TS#46827, etc.), you can utilize a restricted identity function to ensure that the dictionary you create adheres to the expected type, while maintaining its type information intact. Once you've created the object value, simply use keyof typeof value to obtain a type representing its keys:
