A small example of a service worker in typescript along with the tsconfig.json that allows tsserver and IDEs to understand what's going on
View service-worker.ts
// NOTE: We must export or import at least one thing so we are not in
// the "global" scope, but in a module scope which is re-declarable.
//
// The error from tsserver is: 2451: Cannot redeclare block-scoped
// variable 'self'.
//
// Even tho this is not really a module and cannot be: ServiceWorkers
// cannot be modules.

Make a little state object which can be updated through Immer's produce
View create-state.ts
import produce, { Draft, Immutable } from 'immer'
type Updater<S> = (state: Draft<S>) => void | S
type UpdateCallback<S> = (state: Immutable<S>) => void
type State<T> = {
current: Immutable<T>;
update: (updater: Updater<T>) => void;
onUpdate: (cb: UpdateCallback<T>) => void;
