The combination of WebComponents and Storybook provides an ideal solution for building cross-frame, reusable design systems. 1. WebComponents implements style and behavior encapsulation through native browser API to ensure that components are available in any technology stack such as React, Vue, Angular; 2. Storybook provides an isolated delivery environment and supports WebComponents for real-time development, testing and documenting components; 3. When setting up, use npxstorybookinit and select the WebComponents framework, automatically configure main.js and preview.js, and write components in combination with Lit and other libraries; 4. Components

Create users table to store user information, use VARCHAR (255) to save hash password; 2. Encrypt password with password_hash() when registering and use preprocessing statements to prevent SQL injection; 3. Verify password through password_verify() when logging in and establish a session; 4. Use session_start() to manage sessions and check login status on sensitive pages; 5. Implement HTTPS, preprocessing statements, CSRF tokens, speed limits and secure session settings and other security measures; 6. The "Remember Me" function requires storing hash tokens and setting secure cookies; 7. Password reset should generate a hash token with valid period and send links via email; finally, comprehensive testing is required,

Separate commands and queries: Use CQRS to decouple write operations (such as CreateUser) from read operations (such as GetUserById), the command side processes business logic and saves events, and the query side quickly obtains data from optimized read tables (such as users_view); 2. Implement event traceability: Record and playback events (such as UserCreated) through the aggregate root (AggregateRoot), state changes are persisted in the form of events, supporting audit, debugging and state reconstruction; 3. Build event storage: Use MySQL and other databases to store event streams, load event sequences according to the aggregate ID to reconstruct aggregate instances; 4. Update the read model: Synchronize events through the projector or

Go's plug-in system is based on the plugin package and only supports the amd64 platform of Linux and macOS. It uses gobuild-buildmode=plugin to generate .so files; 2. The main program and the plug-in need to share interface definitions, and type consistency is achieved by importing the same interface package; 3. The plug-in must be written in Go and exported variables that match the interface; 4. The main program loads the plug-in through plugin.Open, uses Lookup to find the export symbols and assert as the interface type; 5. Multiple plug-ins can be dynamically loaded by traversing the directory to achieve modular expansion; 6. This solution has problems such as platform restrictions, no version management, and no sandbox. gRPC, WASM or embedded scripts can be considered as alternatives;
