This is the third iteration of my simple weather station using an AM2302 sensor, this time with a SvelteKit web app and SQLite.
The system has two parts:
- Base station with sensor, taking regular measurements and uploading them to the backend whenever it has connectivity
- Backend and client for storing and interacting with current and historical readings
What's cool about it?
- With Svelte and SvelteKit it's possible to develop incredibly lightweight applications. In fact, this one doesn't even require JavaScript on the client to work.
- SQLite's file-as-DB approach is perfect for this kind of application.
- The whole project is extremely minimal and simple. In terms of logic, it only has 300+ lines of actual code for both the base station and backend + client. Granted, it's a very basic use case with only a single page and going for a full framework like SvelteKit is overkill, but I really wanted to try 1.0 now that it's out and I couldn't be happier with it.
- All of the above makes for a really fast page and it does get a perfect
performance score on PageSpeed Insights.
