Solid.js is a high-performance, virtual DOM-free responsive UI library that achieves accurate updates through compilation-time optimization; 2. Use signal systems to achieve fine-grained responsiveness without relying on arrays or cleaning side effects; 3. Performance is better than React/Vue/Svelte, suitable for complex real-time interfaces; 4. Development experience is friendly and common pitfalls of React; 5. Although the ecosystem is not as mature as React, it can be used for production and grow rapidly.

To set up a front-end deployment CI/CD pipeline, the key is to straighten out the process and select the right tools. 1. Select the appropriate CI/CD tools, such as GitHubActions (suitable for small and medium-sized projects), GitLabCI (naturally integrated with GitLab), and Jenkins (suitable for enterprise-level customization); 2. Basic design process: code pull → installation dependencies → execution test → build → deployment, and you can configure the YAML file to implement through GitHubActions; 3. Select the deployment method according to the project, such as static hosting (Netlify, Vercel), self-built server (Nginx), cloud platform (AWSS3); 4. Notes include environment distinction, cache control, failure notification, permissions

The core function of the state management library is to uniformly manage shared states in complex applications and improve the efficiency and maintainability of data flow. When the component level is complex or requires a shared state (such as login status, shopping cart), relying solely on props and event delivery will lead to chaos, and the state management library provides a centralized storage and standardized update mechanism. In the mainstream library, Redux is suitable for large React projects but cumbersome. Vuex is the official Vue solution with clear structure, Zustand is lightweight and suitable for small and medium-sized React projects, and Pinia is the new generation of Vue tools that are more concise and friendly. Its basic structure includes State (storage data), Actions/Mutations (modify status), Getters/Selectors (

The key to using CDN to improve front-end performance is to accelerate static resource loading and reduce access latency. First, select the appropriate CDN service provider, such as Cloudflare, Akamai, AWSCloudFront or domestic Alibaba Cloud and Tencent Cloud CDN, and filter according to the coverage area, price, cache policy, HTTPS support and return to source configuration; second, reasonably split static resources, host JS, CSS, pictures, etc. to the CDN, and classify and manage it. It is recommended to add version number or hash naming to the resource to avoid cache problems; third, enable the cache policy, set the picture and font to one year by setting the Cache-Control and Expires header, set the picture and font to one year cache, and set JS/CSS to several days to several weeks, H

Use the composite component mode to build a collaborative UI, such as Select and its subcomponents share state through Context; 2. Use the rendering attribute mode to share non-visual logic, such as MouseTracker to pass data through function attributes; 3. Select according to the scene: Use composite components when structured layout is required, and use rendering attributes when logic is required to be reused flexibly; 4. The two can be used in combination to take into account both structure and flexibility. The ultimate goal is to design a more maintainable and user-friendly API. There is no universal solution, but both are powerful and practical design patterns in React.

ErrorBoundaries is a component in React that handles runtime errors. It can catch child component errors and display the backup UI. Its core purpose is to prevent component errors from crashing the entire application, and to display friendly prompts and reporting error messages in production environments. ErrorBoundaries catches errors by implementing two lifecycle methods: staticgetDerivedStateFromError() and componentDidCatch(). It should be noted that they do not catch event processing, asynchronous code, server-side rendering, and errors thrown by themselves. It is recommended to place it at critical levels such as page level, module level and third-party component periphery to limit errors
