Article Introduction：When handling multi-file uploads, you need to pay attention to front-end selection and preview, back-end reception and processing, and avoid common problems. 1. The front-end realizes multiple selections, uses FileReader to generate temporary URL preview pictures and release memory in time; the file list should be saved to the status in the framework. 2. The backend such as Node.js can use mult middleware to receive file arrays, and PHP and Python obtain file lists through $_FILES and getlist and process them one by one. 3. Notes include: renaming to avoid file name conflicts, front-end and back-end jointly limit file size, support failed retransmission of individual files, limit concurrency optimization performance, and verify file types to prevent security risks.

Article Introduction：Server-SentEvents (SSE) is a technology that servers push real-time updates to browsers in one-way. It realizes event streaming through persistent HTTP connections, which is suitable for news push, real-time notification and other scenarios. The client uses the EventSource object to listen to messages, and the server sends data in text/event-stream format. Each message contains data (required), event (optional), id (optional), and retry (optional) fields. The front-end can listen for custom events through the addEventListener, and the back-end needs to keep the connection open and output data streams that match the format. SSE does not support IE and legacy Edge, but in modern browsers

Article Introduction：Qwik realizes instantaneous loading through "recoverability": 1. Serialize application status and event listener location when the server renders HTML; 2. The browser directly restores the state rather than performs JS hydration; 3. Load component code as needed during interaction. This brings the advantages of zero-latency response, extremely small JS load and lazy loading, which is suitable for scenarios with large differences in content, SEO sensitivity and performance, but it requires the cost of a small ecosystem and a change in development thinking. It is a new front-end paradigm of "interaction without execution".

Article Introduction：WebSocket is a full-duplex communication protocol provided by HTML5, which allows the browser to establish a persistent connection between the server and realizes efficient real-time data transmission. Its core advantage is that it does not require repeated connection establishment, reduces latency and improves efficiency. When building real-time functions, the front-end creates WebSocket instances through JavaScript and listens to events, and the back-end can use languages ??such as Node.js, Python or Java to process connections and message broadcasts. Common application scenarios include chat applications, online collaborative editing, real-time data display and notification systems. During development, you need to pay attention to cross-domain issues, connection maintenance mechanism, compatibility, back-end concurrent pressure and security details, and combine Redis or Nginx to improve performance and expansion if necessary.

Article Introduction：WebAuthn is a key technology for H5 biometric authentication. It realizes fingerprint, facial recognition and other verification methods through browsers. At its core, it uses a public key encryption mechanism for authentication without a username and password. The access process is divided into two steps: registration and login: the front-end calls navigator.credentials.create() and navigator.credentials.get() respectively, and cooperates with the back-end to complete credential generation and verification. There are four key points to be noted: 1. Browser compatibility; 2. Must run in an HTTPS environment; 3. Users need to actively interact and trigger; 4. Correctly configure CORS and RPID. In actual applications, mobile support issues need to be dealt with and bootstrap for the first time
