Course Introduction:Keepalives in Vue are used to cache component instances to maintain their state. They can be used by wrapping Keepalive components around child components. Key benefits include: state preservation, performance optimization, and data recovery. Keepalive supports include, exclude, max, and deactivationHook attributes, and is suitable for scenarios where state needs to be maintained, performance optimized, or user input restored.

Course Introduction:The default request header of the http1.1 protocol is to enable keepalive by default, as shown in the figure: So what is keepalive? What is the function? Keepalive is a mechanism in TCP that can detect dead connections. Its function is to keep long socket connections from being disconnected. It is a function of the TCP layer and does not belong to the application layer. How does the tcp layer maintain a long connection? Let’s look at the usage of keepalive first: there are three parameters, open to the application layer: sk->keepalive_probes: the number of detections, the number of retries sk->keepalive_time, the heartbeat interval of the detection, and how many seconds after the tcp link has no data packet transmission to start the detection packet

Course Introduction:1. Keepalive function keepalive is a global component in vue3. Keepalive itself will not be rendered, nor will it appear in the dom node, but it will be rendered as a vnode. The cache and keys in the keepalive can be tracked through the vnode, of course. It is only possible in the development environment. After the build is packaged, it is not exposed to the vnode (this needs to be confirmed again). The most important function of keepalive is to cache the component. Keepalive updates the component cache through the LRU cache elimination strategy, which can make more effective use of memory and prevent memory leakage. Overflow, the maximum number of caches in the source code is 10, that is, 10 groups

Course Introduction:This article brings you a detailed explanation of how to use keepalive in the Vue project. Keepalive is a built-in component of Vue. Its function is to cache components in memory to prevent repeated rendering of the DOM, which consumes memory acquisition speed. I hope everyone has to help.
