SvelteKit VS React

SvelteKit

You can share classes in Svelte, but safely sharing them in SvelteKit, requires a bit more code...

Image processing #241

Per-User Limits: Track requests on a per-user basis using their IPv4 address. We’ll leverage SvelteKit to easily retrieve the client IP with its built-in method.

For our application, I wanted to spin up a simple framework example app, so I went with SvelteKit. It’s easy to bootstrap, and it has a smooth looking getting started application. I followed the instructions here to initialize a new project:

Early in my career, I struggled to understand how React’s state updates actually worked. Docs gave me the basics, but edge cases around batching were confusing. One weekend, I pulled up the React source code on GitHub and traced how state changes bubbled through the scheduler. Suddenly, the “weird bugs” I hit at work made sense because I wasn’t guessing anymore, I’d seen the engine.

3. Next.js and React (Frontend framework)

My primary passion is backend development, but I wanted to build a user-friendly frontend to complete this project. Given my experience with React, Next.js was the obvious choice due to its excellent documentation and ease of use.

At IVAO, we partially follow micro-services best practices. This means each business group (e.g., Flight tracking, Flight planning, Air Traffic controlling, Training) has its own NestJS API and ReactJS frontend. But we took a shortcut on the DB side, as we have quite some references across systems, especially for user IDs, airports, etc... We decided to have a single MariaDB instance while having a dedicated logical database for each API, so we still have a separation of concerns but we can guarantee data integrity with foreign keys across those databases.
