Get Repository Topics

About​

  • The getRepositoryTopic function, implemented as an asynchronous route handler in Express.js, serves to retrieve and communicate the topics associated with a particular GitHub repository for a given user. The function starts by verifying the user's existence in the database, throwing a UserNotFoundError if the user is not found. It then proceeds to fetch the user's repository collection using the GitHub repository ID, and if no collection is found, a FetchToFailRepositoriesError is thrown. Subsequently, the function searches for the specified repository by name within the collection, throwing a FailtoFetchSingleRepoByName error if the repository is not found. Upon locating the repository, the function responds with a JSON object containing the topics extracted from the repository's repo_topics property. The function incorporates robust error handling to address scenarios such as user not found, failure to fetch repository data, or the absence of the specified repository by name, ensuring informative responses in each case.
