I'm working on a sync engine. Took a while to even get this small demo working

I didnt realize how annoying app icon badges are until now. Do not disturb on iOS 18 turns them off for every app now. Looking at my screen is so much more pleasant 👀

Here is what the end result API looks like:
const addTask = useTransaction((tx, after?: TaskId) => { let positionToGoAfter: string | undefined = undefined; if (after) { const taskToGoAfter = tx.get("tasks", after); if (!taskToGoAfter) { throw new Error("Task to go after not found"); } positionToGoAfter = taskToGoAfter.position; } const position = positionSource.createBetween(positionToGoAfter); const id = newTaskId(); tx.set("tasks", { id, text: "", position, status: { type: TaskStatusType.Inbox }, }); setFocusedTask(id); });

Got basic storage sync to expo-sqlite working. The mutations are completely local which feels great.

Wrote down a list of things I want/expect from a sync engine/realtime database. This will be the set of goals as I go forward building my library
- [ ] Sync to client storage - [ ] Eventually consistent sync to server (handle conflict resolution sanely) - [ ] Offline support - [ ] Queries - [ ] Where - [ ] Sort - [ ] Limit - [ ] Sync status: is the value optimistic or has it been confirmed - [ ] Mutations - [ ] Preserve *intent* over the wire: not just sending set/deletes. - [ ] Very simple query planner: using where/sort should always use an index. It should be obvious when an API you're using is doing a full table scan. - [ ] End-to-end reactivity - [ ] Pre-fetch: Fetch data early without necessarily subscribing - [ ] Schemas - [ ] Migration support/plan - [ ] Some understandable simple solution to conflict resolution - [ ] Rollback on storage or remote failure - [ ] "Replay" local optimistic mutations on top of incoming remote changes

I'm going to try and use Bluesky as a place to share more in-progress work. My winter break project right now is to try and build my interpretation of a sync engine. Alongside it, I'm building a todo list app as a "real use case".
iPhone simulator with todo list app running. The app is on the Inbox screen, with one unchecked todo item "Groceries in one hour". The "in one hour" section is highlighted green, and the text "Sun, Nov 24 @ 1pm" is written underneath it.
