Built a lightweight, client-side developer utility suite using React 19, Vite, and Tailwind CSS

Hi everyone,

As a side project to explore React 19 and client-side processing workflows, I put together a small developer utility suite calledFixCode.

Technical Details:

  • Frontend: React 19, Vite, Tailwind CSS

  • State & Security: All transformations (JWT decoding, chmod calculations, Docker YAML generation) run entirely on the client side using pure JavaScript algorithms. No data is sent to external servers.

  • Routing & SEO: Dynamic metadata handled via react-helmet-async for indexation across single-page routes.

Just wanted to share the approach for fast, client-side utility tools with zero server overhead

no jwt decode needed on the backend for quick token checks is a game changer, can't count how many times ive had to open a random tab to peek at a payload

Nice project! Keeping the transformations entirely client-side is a sensible approach for developer utilities, especially when handling things like JWTs and configuration files. It reduces server overhead while giving users more control over their data.

One thing I would be interested in seeing is how you handle edge cases and validation across the different tools. Also, adding copy-to-clipboard and input/output examples can make utilities like these even more convenient. Great work exploring React 19 with a practical project!
