Streamline the TypeScript interface for retrieved data from an API

I am looking to retrieve movie data from the omdbapi.

Currently, I am experimenting with incorporating typescript to precisely define the data fetched from the endpoint (I am still learning typescript).

When examining the structure of the retrieved data, I ponder if it is truly necessary to individually list all the data in the interface if it is a string?

interface Movie {
  Title: string;
  Year: string;
  Rated: string;
  Released: string;
  Runtime: string;
  Genre: string;
  Director: string;
  Writer: string;
  Actors: string;
  Plot: string;
  Language: string;
  Country: string;
  Awards: string;
  Poster: string;
  Ratings: [
    {
      Source: string;
      Value: string;
    },
    {
      Source: string;
      Value: string;
    },
    {
      Source: string;
      Value: string;
    }
  ];
  Metascore: string;
  imdbRating: string;
  imdbVotes: string;
  imdbID: string;
  Type: string;
  DVD: string;
  BoxOffice: string;
  Production: string;
  Website: string;
  Response: string;
}

Answer №1

If you're looking to define a type in TypeScript that includes an object with keys mapping to strings, consider using the Record utility type:

type Movie = Record<"Title" | "Year" | "... add more keys here ..." | "Website" | "Response", string> & {
  Ratings: {
    Source: string;
    Value: string;
  }[];
};

To accomplish this, create a union of all the keys that correspond to strings and then intersect the record with an object type specifying the structure for Ratings.
