set

v0.0.14testeddemo

Shorthand setter that mirrors get. Either assigns value to a ref (ref.value = value) or assigns value to a single property of an object (target[key] = value). The arity is resolved at the type level via overloads, so both forms stay fully type-safe. Purely synchronous and side-effect free, so it is fully SSR-safe.

Source Tests

Examples

const count = ref(0);
set(count, 5); // count.value === 5

const user = reactive({ name: 'Ada' });
set(user, 'name', 'Grace'); // user.name === 'Grace'
