Typescript's intricate data structures

I'm looking to communicate a string in my design that includes indexes, with the possibility of ending the string with either "work" or "crash":

export interface Test {
    date: string,
   'stat.conv[index: number].key[index: number].(work || crash)': Test2[]
}

Does TypeScript support this kind of syntax?

Answer №1

To establish the keys, utilize a template literal type within the interface:

export interface Information {
    date: string;
   [key: `stat.conv[${number}].key[${number}].${'work'| 'crash'}`]: any;
}

const info: Information = {
  date: '',
  'stat.conv[0].key[0].work': '', // Valid
  'stat.conv[1].key[1].crash': '', // Valid
  'stat.conv[x].key[y].work': '', // Invalid
  'stat.conv[0].key[0].nothing': '' // Invalid
}
