Welcome back! In my last post, I introduced you to Dvori, a project born from my desire to create a more adaptable and user-friendly JavaScript HTTP client. With the groundwork of concepts and design principles laid, it was time to roll up my sleeves and turn those ideas into reality. Let’s delve into the early stages of Dvori's development, where concepts begin to materialize into code.
Defining Core Interfaces and Types
The first step in bringing Dvori to life involved defining the core TypeScript interfaces. This crucial stage established a clear blueprint for ClientConfig, RequestConfig, and the structure of composables. Emphasizing type safety from the get-go was paramount, ensuring that Dvori would offer a robust and predictable API.
Developing the fetchWrapper
With the blueprints in hand, my attention turned to developing fetchWrapper.ts. This component is Dvori’s engine, abstracting the fetch API to enhance its usability and reliability. Implementing features like automatic error handling for non-2xx responses and URL resolution against a baseURL were top priorities, addressing common pain points I’d encountered in the past.
Implementing defineClient and defineComposable
The heart of Dvori's architecture, defineClient and defineComposable, came next. These functions encapsulate the library's philosophy of flexibility and ease of use. In particular, organizing composables by their lifecycle steps within defineClient proved to be a game-changer, streamlining the process of enhancing requests with custom logic and behavior.
Testing and Iteration
With the core functionality taking shape, rigorous testing with Vitest became my focus. Writing tests not only validated Dvori's behavior under various scenarios but also illuminated areas for improvement, guiding further iterations of the code. This feedback loop was invaluable, driving refinements that brought Dvori closer to my vision with each cycle.
Wrap-Up
Reflecting on the journey from concept to code, the development of Dvori has been both challenging and immensely rewarding. The process of defining, implementing, and testing the library's foundational components has solidified my understanding and appreciation for the nuances of creating developer tools. As Dvori evolves, I look forward to sharing more insights, challenges, and milestones with you.
In the meantime, I encourage fellow developers to embark on their own projects, however daunting they may seem. The journey of creation is filled with learning and growth at every turn.
Happy coding, and see you in the next update!
