Programs deployed to Membrane are durable. There's no need to store data in a database because the entire state of your program (i.e. the JS heap) is continually and efficiently persisted.

To keep data around, just put it in the state object and that's it!

Promises can be await'ed indefinitely without worrying about execution timeouts.

import { state } from "membrane";
state.notes = state.notes ?? []
export async function saveNote({ args }) {
  state.notes.push(args.note);
}
