Text dictionary with optional keys

TermDictionary.ts

// If you need to create a text dictionary with not all of it keys
type TermDictionary<TKey extends string> = Partial<Record<TKey, string>>;


type StatusUnion = 'Success' | 'Error' | 'Unknown';

enum StatusEnum { 
  Success, 
  Error,
  Unknown,
};

const messagesByUnion: TermDictionary<StatusUnion> = {
  Success: 'Ok',
  Error: 'Not Ok',
  // Unknown: 'Something went wrong', // ✅ Not every single key is required
}

// Enums are runtime objects, so you have to extract their type with 'keyof' + 'typeof' operators
const messagesByEnm: TermDictionary<keyof typeof StatusEnum> = {
  Success: 'Ok',
  Error: 'Not Ok',
  // Unknown: 'Something went wrong', // ✅ Not every single key is required
}
