New Features & Enhancements

  • New Feature: Added the ability to send a request without saving the endpoint.

    • What it does: allows the user to run API requests without saving.
    • Justification: This feature improves the product significantly because a user can quickly type in an API URL with the required details, and the app will conveniently trigger a request for the user to view the response.
    • Highlights: This feature involves two variations of command format that can be accepted. It required an in-depth analysis of command parsing order ensuring user inputs are treated correctly. The implementation too was challenging as it required changes to how we verify the validity of URLs.
  • New Feature: Added a keyboard shortcut that allows the user to retrieve the previous valid command using ctrl + up-arrow (Windows) / cmd + up-arrow (macOS).

  • New Feature: Added a help command that allows the user to open a pop up window displaying relevant links such as the product’s user guide and also a table of command summary for quick reference.

  • New Feature: Added a show command that allows the user to view the details of a saved endpoint.

  • Enhancements:

    • Refactored code in the request calling logic, and the handling of command result to reduce duplication and improve code quality.
    • Fixed issues related to user input (such as the integer index) involved in various commands to ensure bugs are caught and relevant error messages are provided.
