Eager computed without lazy evaluation.
Learn more at Vue: When a computed property can be the wrong tool.
- Use
computed()
when you have a complex calculation going on, which can actually profit from caching and lazy evaluation and should only be (re-)calculated if really necessary. - Use
computedEager()
when you have a simple operation, with a rarely changing return value – often a boolean.
Usage
import { computedEager } from '@vueuse/core'
const todos = ref([])
const hasOpenTodos = computedEager(() => !!todos.length)
console.log(hasOpenTodos.value) // false
toTodos.value.push({ title: 'Learn Vue' })
console.log(hasOpenTodos.value) // true
