vue big screen is too stuck

In the development of front-end large screens, the Vue framework is a very popular technology. It enables you to quickly build interactive large-screen and data visualization applications. But sometimes, when the amount of data is too large or the logic is too complex, Vue large-screen applications may become stuck, giving users a bad experience. So, how to solve the problem of Vue large screen lagging?

1. Data optimization
   Data are the core of Vue applications, they provide all the information that needs to be displayed. Therefore, an optimized data set can improve the performance of Vue large-screen applications.

First, you can use a suitable data structure. For example, for some data that requires frequent filtering and querying, using Map or Set can improve performance. Secondly, narrow the scope of the data and only load and display the data currently needed instead of loading all the data at once. At the same time, you can try to avoid complex data operations in the loop, which will make the loop slow.

2. Component Optimization
   Large-scale Vue applications will involve many components. Therefore, component performance optimization is the key to improving the performance of Vue applications.

First of all, data and calculation can be separated. This reduces redundant calculations, which will make the component render much faster. Secondly, use v-once and v-if instructions as much as possible. The former can reduce repeated rendering of components, and the latter can avoid unnecessary rendering and reduce unnecessary DOM operations. Finally, multiple levels of nesting in components should be avoided whenever possible.

3. Detailed optimization
   In addition to the above two optimizations, some details can also improve the performance of Vue large-screen applications. For example:

Use asynchronous data requests to avoid blocking the main thread.

Use cache to reduce the response time of each request.

Enabling Vue devtools can help you analyze page rendering speed and identify components that need optimization.

Use isolation mode. Using isolation mode in components can avoid unnecessary data updates between sub-components.

Using lazy loading, components can be loaded on demand at any time.

Summary

For Vue large-screen applications, optimization is a continuous iterative process. Only through continuous testing and iteration can performance and user experience be continuously improved. Therefore, you must pay attention to performance issues during the development process and constantly look for optimization opportunities, so that Vue large-screen applications can achieve the best results.
