app.watch

Calls listener when the system warns that memory runs low. In a component it stops when the component unmounts; elsewhere the returned subscription stops it.

Refresh on return and release cached data

tsx

const cache = new Map<string, ArrayBuffer>();

app.state.value; // 'active' | 'background' | 'inactive'

export function Feed() {
  // Both follow the platform until the component unmounts.
  watch(app.state, (state) => {
    if (state === 'active') refresh();
  });
