The document provides a comprehensive guide for building and integrating a Kotlin full-stack architecture, structured into 10 modules across 12 levels, totaling 120 components. The process includes phases for obtaining components, integrating modules, connecting across modules, and validating the project. ### Key Phases: 1. **Component Acquisition**: - Create a main directory and a particle library. - Follow a specific order for modules and levels, with a naming convention for files. 2. **Module Integration**: - Set up server and client directories. - Integrate components in a defined sequence, categorizing content into configuration, code, and SQL. 3. **Cross-Module Connection**: - Establish connections in a specified order and create adapters for interface compatibility. 4. **Project Validation**: - Conduct checks on the server and client sides, ensuring all core scenarios function correctly. ### Directory Structure: The final project structure includes organized directories for each module, with specific files for configurations, implementations, and tests. ### Important Guidelines: - Follow strict order rules for module and level integration. - Implement version control and backup strategies. - Address issues promptly with defined solutions. ### Performance and Security: Maintain performance benchmarks and ensure security checks are in place for critical components. ### Final Checklist: - Verify the completeness of directories and dependencies. - Conduct performance tests and validate business flows. The guide emphasizes a systematic approach to ensure a successful full-stack architecture integration.

โ–ธ ๐Ÿ“ฑ Client: Core Business Process Closed Loop

โœจ Operation Mnemonic:
Create Directory โ†’ Acquire Granules โ†’ Integrate Modules
Connect Systems โ†’ Validate Scenarios โ†’ Form Project

๐Ÿ”ฅ Key Tips:
Prioritize completing Database_L1 (System Layer) and Controller_L3 (Security Layer)
Can prevent 80% of integration issues!

โฑ๏ธ Performance Benchmark:
Server Response < 500ms | Client Load < 1 second

๐Ÿ›ก๏ธ Security Points:
Must Check Database_L3 (TLS Encryption) + Controller_L3 (JWT Authentication)

๐Ÿšจ Common Pitfalls Reminder#

โ–ธ โš ๏ธ Connection Order Trap
Server Controller must be completed before starting Client DataSource module
Skipping levels will cause compilation errors
โ–ธ โœ๏ธ Version Control Points
Update version number after modifying granule files
Key backup nodes: End of Phase 1/3/5
โ–ธ ๐Ÿ”ง Adapter Creation Rules
Create only when interface issues are found during validation phase
Must record adaptation reasons and solutions

๐ŸŒˆ Success Secret:
Strictly follow the 10 module order
Refer to global-adapters case library when encountering issues
Validate immediately after completing each phase!

๐Ÿ“‹ Final Checklist#

๐Ÿ” 10 Module Directory Fully Created
๐Ÿ”— Cross-Module Dependency Relationships Clearly Marked
๐Ÿ›ก๏ธ Security Layer (L3) Double Validation
โšก Performance Benchmark Testing Standards Met
โœ… Three Scenario Business Flow Closed Loop Validation

๐ŸŽ‰ Completion Declaration:
When the 10 modules are perfectly integrated, and all three scenario tests are green-lit
Your full stack architecture is ready!
