Vue 3 相比 Vue 2 性能提升的详细分析

Date: 1/12/2022Category: Category A, Category BTag: tag C, tag D

Vue 3 在多个方面对性能进行了优化,下面我们将详细分析这些改进的具体内容。

1. 虚拟 DOM 重写(性能优化)

在 Vue 2 中,虚拟 DOM 的实现主要是基于 Object.defineProperty 来劫持数据变动,但在对比和更新虚拟 DOM 时,Vue 2 会存在一些性能瓶颈,特别是在较大应用中更新频繁的情况下。

在 Vue 3 中,虚拟 DOM 的算法被重新设计,采用了 更精确的 diff 算法,同时通过 Proxy API 让 Vue 能够更高效地追踪数据变化,避免了 Vue 2 中需要进行繁琐的递归遍历和更新的过程。Vue 3 的虚拟 DOM 更新方式能够 更小颗粒度的 diff 操作,只更新需要变动的部分,而不是全量更新。
