eagerComputed

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 eagerComputed() when you have a simple operation, with a rarely changing return value – often a boolean.

Usage

import { eagerComputed } from '@vueuse/core'

const todos = ref([])
const hasOpenTodos = eagerComputed(() => !!todos.length)

console.log(hasOpenTodos.value) // 0
toTodos.value.push({ title: 'Learn Vue' })
console.log(hasOpenTodos.value) // 1

Type Declarations

export declare function eagerComputed<T>(fn: () => T): Readonly<Ref<T>>
