Interface: Atom<T>

API / @xmachines/play-atom / Atom

Defined in: types.ts:117

The writable atom. It holds one reactive value

A get() call inside a computed atom or inside a subscription tracks the atom as a dependency. A set() call notifies every computation and every observer that depends on the atom. set accepts a value, and it accepts a function of the previous value.

Example

import { createAtom } from "@xmachines/play-atom";

const name = createAtom("Alice");
console.log(name.get()); // "Alice"
name.set("Bob");
name.set((previous) => previous.toUpperCase()); // "BOB"
