alien-signals with a Preact signals like API and a class based approach for easy brand check.
import {
Signal,
signal, computed,
effect, untracked,
// all other alien-signals exports
} from '@webreflection/alien-signals';
const count = signal(0);
const double = computed(() => count * 2);
// implicit count.valueOf()
console.assert(count instanceof Signal); // true
console.assert(double instanceof Signal); // true
effect(() => {
console.log('count', count.peek());
// no subscription
console.log('double', double.value);
});
count.value++;
A signal created via signal(value, { greedy: true }) will effect any time the same value is set again, as opposite of ignoring the explicit set operation.
