What are the advantages and disadvantages of spa developed by vue?
Advantages: 1. Good interactive experience; 2. Separation of front-end and back-end, reducing development efficiency; 3. Clear architecture; 4. Reduce the pressure on the server. Disadvantages: 1. Not friendly to SEO; 2. The first screen may take too long to load; 3. The page complexity increases and the complexity of the logic is doubled.
The operating environment of this tutorial: windows7 system, vue2.9.6 version, DELL G3 computer.
What is SPA?
Single-page Web application (single-page application, referred to as SPA) is a special kind of Web application. It limits all activities to a Web page and only loads the corresponding HTML, JavaScript and CSS when the Web page is initialized. Once the page is loaded, SPA will not reload or jump the page due to user operations. Instead, JavaScript is used to dynamically transform the content of HTML to achieve interaction between the UI and the user. SPA can provide a smoother user experience by avoiding page reloading.
What are the advantages of SPA?
1. Good interactive experience
Because it is partial rendering, each part is a separate module. Avoid unnecessary jumps and repeated rendering
2. Separation of front-end and back-end reduces development efficiency.
3. Clear structure.
4. Reduce the pressure on the server.
The server only needs to provide data and does not need to worry about front-end display logic and page synthesis, which improves performance.
5. Share a set of back-end program codes.
What are the disadvantages of SPA?
1. Not friendly to SEO
2. First screen loading may occur Too long time problem.
(In order to realize a single page. It is necessary to load js and css uniformly on the loading page, and some pages are loaded on demand)
The white screen is caused by the long loading time of the first screen, how to solve? You can use the skeleton screen effect
3 to increase the page complexity.
The complexity of the logic is doubled.

Use Context and useState to share states because they simplify state management in large React applications. 1) Reduce propdrilling, 2) The code is clearer, 3) It is easier to manage global state. However, pay attention to performance overhead and debugging complexity. The rational use of Context and optimization technology can improve the efficiency and maintainability of the application.

Using incorrect keys can cause performance issues and unexpected behavior in React applications. 1) The key is a unique identifier of the list item, helping React update the virtual DOM efficiently. 2) Using the same or non-unique key will cause list items to be reordered and component states to be lost. 3) Using stable and unique identifiers as keys can optimize performance and avoid full re-rendering. 4) Use tools such as ESLint to verify the correctness of the key. Proper use of keys ensures efficient and reliable React applications.

useState is often misused in React. 1. Misunderstand the working mechanism of useState: the status will not be updated immediately after setState. 2. Error update status: SetState in function form should be used. 3. Overuse useState: Use props if necessary. 4. Ignore the dependency array of useEffect: the dependency array needs to be updated when the state changes. 5. Performance considerations: Batch updates to states and simplified state structures can improve performance. Correct understanding and use of useState can improve code efficiency and maintainability.

React performance bottlenecks are mainly caused by inefficient rendering, unnecessary re-rendering and calculation of component internal heavy weight. 1) Use ReactDevTools to locate slow components and apply React.memo optimization. 2) Optimize useEffect to ensure that it only runs when necessary. 3) Use useMemo and useCallback for memory processing. 4) Split the large component into small components. 5) For big data lists, use virtual scrolling technology to optimize rendering. Through these methods, the performance of React applications can be significantly improved.

Someone might look for alternatives to React because of performance issues, learning curves, or exploring different UI development methods. 1) Vue.js is praised for its ease of integration and mild learning curve, suitable for small and large applications. 2) Angular is developed by Google and is suitable for large applications, with a powerful type system and dependency injection. 3) Svelte provides excellent performance and simplicity by compiling it into efficient JavaScript at build time, but its ecosystem is still growing. When choosing alternatives, they should be determined based on project needs, team experience and project size.
