Migrating Ekehi from Vanilla JS to a TypeScript Stack
The Ekehi platform transitioned from a static client built with hand-written HTML/CSS/JS pages to a modern, typed tech stack. This overhaul involved replacing the old client with a React 19-based, client-side SPA rendered through Vite 8 and routed by TanStack Router. The choice of TanStack Router over React Router was driven by its type-safe routes, first-class search-param typing, built-in code-splitting, and file-based route generation that integrates well with Vite. The server-side Express API was also upgraded to use TypeScript, adopting a module-per-domain structure.
This migration aligns with the broader trend of modernizing web development stacks to leverage the benefits of type safety, component-driven architecture, and efficient development workflows. The adoption of React 19, Vite 8, and TypeScript reflects the growing preference for these technologies in building scalable and maintainable web applications. The use of TanStack Router and TanStack Query indicates a strategic focus on integrating robust, type-safe solutions for routing and server-state management.
The implications of this migration are significant, as it sets the stage for more efficient development, better code maintainability, and enhanced user experience. However, there are risks associated with such a major overhaul, including potential disruptions during the transition and the learning curve for developers adapting to the new tech stack. Key areas to watch next include the performance impact of the new stack, the effectiveness of the type-safe routing and server-state management, and how these changes enable future development and feature additions.
Key Takeaways
Ekehi adopted React 19, Vite 8, and TanStack Router for its client-side SPA, enhancing type safety and development efficiency.
The migration involved a two-phase rewrite, starting with the client and followed by the server, which was upgraded to use TypeScript and a module-per-domain structure.
The new tech stack includes Tailwind CSS 4 for styling, with a focus on role-based token names and deterministic class ordering.
The platform now utilizes TanStack Query for server-state management, integrated with a typed HTTP client for improved data fetching and error handling.
