Vue的keep-alive组件是用来进行组件缓存的。它可以在特定的场景下使用,比如需要缓存某个组件或者缓存所有组件。\[1\]要缓存某个组件,可以在该组件的外层嵌套一层<keep-alive>标签,并将需要缓存的组件放在<keep-alive>标签内部。例如,在APP.vue中缓存NativeBtn组件可以这样写:<keep-alive><NativeBtn /></keep-alive>。\[2\]如果需要缓存所有组件,可以将<keep-alive>标签放在根组件的外层,并将<router-view>放在<keep-alive>标签内部。例如,在APP.vue中缓存所有组件可以这样写:<keep-alive><router-view /></keep-alive>。这样,在路由切换时,被缓存的组件将会保留其状态,而不会重新渲染。
