Get Repository Language

About​

  • The getRepositoryLanguages function, an Express.js route handler, retrieves details about programming languages and their corresponding code sizes in a user's GitHub repository. It begins by validating the user's existence and fetching the associated repository document. Utilizing getRepositoryBuildLang for language information, the function updates the repository document with details on each language and its code size. The response consists of a JSON object containing language information. Robust error handling includes scenarios like user not found (UserNotFoundError), repository absence (RepositoryNotFoundError), language information retrieval failure (FailedToFetchRepositoryLanguages), or internal server errors, providing precise error responses for each case, ensuring a seamless user experience.
