SQLite gives you just the "data fetching" part. But if you're building a React/RN app, you probably also want everything to be automatically observable.

For example, if you have a todo app, and you mark a task as done, you'd want the task component to re-render, the list to re-render (put the task at the bottom), and update the right counters (the counter of all tasks, and a counter of all tasks in ta project), etc. I hope you're getting the point.

Watermelon is an observable abstraction on top of SQLite (or an arbitrary database), so that you can connect data to components and have them update automatically




Thanks for this concise example! This helped me to understand why I should try it out, and led me to demoing this myself. I'll report back my findings


So is it fair to say its a React specific ORM, that automatically makes the mapped objects observable (an OORM, if you will)? Just trying to understand the level of abstraction that you're going for.


That's a fair description, yeah!


Does that mean that if user A makes an update to the database, then user B (on a different computer) will see the update?


No, Watermelon is a local app database. But you can plug it into a sync engine to synchronize with the server (and then from the server to another device) — it's up to you
