🌟 Kotlin Full Stack Architecture Granular Generation and Integration Guide — Author: Wang Jiao Cheng#
🚀 Core Solution#
✨ 10 modules × 12 levels = 120 granules
🔄 Process: Granule Acquisition → Module Integration → Cross-Module Connection → Comprehensive Verification
🧰 Tools: Text Editor + File Manager
🧩 Granule Acquisition Phase#
📌 Create Main Directory: fullstack-app
📂 Establish Granule Library: fullstack-app/particles
🔢 Acquisition Rules:
▸ Module Order: Database → Entity → Repository → Service → Controller → Data Source → Repository → UseCase → ViewModel → UI
▸ Level Order: Each module from L0→L1→...→L11
📝 File Specification: module_name_Llevel_number.txt
💎 Example First Granule: Database_L0.txt
🏗️ Module Integration Phase#
🔧 Create Module Directory:
▸ 🖥️ Server: server/module_name
▸ 📱 Client: android/module_name
🔄 Processing Flow:
▸ Integrate in order L0→L1→...→L11
▸ Content Classification Storage:
⚙️ Configuration → config folder
💻 Code → src folder
🗃️ SQL → migrations folder
🔍 Key Checks:
✅ Class Structure and Method Mapping ✅ Full Security Coverage ✅ Atomic Operations Correct
🔗 Cross-Module Connection#
🔌 Connection Order:
🔹 Database → 🔹 Entity → 🔹 Repository → 🔹 Service → 🔹 Controller → 🔹 Data Source → 🔹 Repository → 🔹 UseCase → 🔹 ViewModel → 🔹 UI
🛠️ Interface Adaptation:
▸ Create global-adapters directory
▸ File Naming: source_target_Adapter.txt
💡 Solutions:
▸ 🔄 Data Format → Conversion Instructions
▸ ↔ Parameter Mismatch → Mapping Relationship
▸ ⏱️ Timing Issues → Execution Order
🧪 Project Verification#
🖥️ Server Checks:
▸ ✅ Structure Complete ▸ 🌐 API Response Testing
📱 Client Checks:
▸ 🔄 Data Flow ▸ 👆 Interaction Logic
🛒 Core Scenario Testing:
🔸 Registration → Login
🔸 Browsing → Ordering
🔸 Payment Settlement
📂 Directory Structure and Function Details#
🧩 Initial Granule Library Structure#
▸ 📁 fullstack-app/particles/Database/
▸ 📄 Database_L0.txt → Business Ecosystem Layer Definition (L0)
▸ 📄 Database_L1.txt → MySQL High Availability Configuration (L1)
▸ 📄 ...other level files
▸ 📁 fullstack-app/particles/Entity/
▸ 📄 Entity_L0.txt → Entity Basic Definition (L0)
▸ 📄 ...other level files
▸ 📁 fullstack-app/particles/...
(Other 8 modules organized in the same structure)
🏗️ Final Project Structure#
▸ 🖥️ fullstack-app/server/Database
▸ ⚙️ config/ → L1 System Layer Configuration
▸ 🗃️ migrations/ → L5 Package Structure Layer Scripts
▸ 💾 schema.sql → L9 Table Structure Definition
▸ 🖥️ fullstack-app/server/Entity
▸ 🧩 entities/ → L6 Class and Interface Layer Implementation
▸ 🧩 embeddable/ → L5 Package Structure Layer Components
▸ 🖥️ fullstack-app/server/Repository
▸ 📦 interfaces/ → L6 Repository Interfaces
▸ 🔍 implementations/ → L7 Custom Queries
▸ 🖥️ fullstack-app/server/Service
▸ ⚙️ impl/ → L7 Business Method Implementation
▸ 📣 events/ → L9 Domain Events
▸ 🖥️ fullstack-app/server/Controller
▸ 🌐 api/ → L6 Class Definitions
▸ 🔄 dto/ → L10 Expression Layer DTO Conversion
▸ 📱 fullstack-app/android/DataSource
▸ 📡 api/ → L6 Retrofit Interface
▸ 💾 local/ → L1 Caching Strategy

▸ 📄 Controller_DataSource_Adapter.txt → Interface Adaptation Plan
▸ 🧪 fullstack-app/validation
▸ 📄 user-register-flow.txt → User Registration Process Testing
▸ 📄 product-order-flow.txt → Product Ordering Testing
⚠️ Key Points#
🚫 Order Iron Rule
▸ Module Sequence: Database→UI is irreversible
▸ Level Sequence: L0→L11 cannot be skipped
🔖 Version Control
▸ File Header Mark: Version V1.0|Date
▸ Backup every 20 granules
❗ Problem Solving
▸ Content Missing → Reacquire Granules
▸ Interface Exception → global-adapters Plan
▸ Logic Conflict → Business Priority Decision
⚡ Efficient Strategy#
📅 Batch Processing:
▸ 🟢 Phase One: Server Basic Layer (Database+Entity)
▸ 🔵 Phase Two: Server Business Layer (Repository+Service)
▸ 🟣 Phase Three: Server Interface Layer (Controller)
▸ 🟡 Phase Four: Client Data Layer (DataSource+Repository)
▸ 🟠 Phase Five: Client Presentation Layer (UseCase+ViewModel+UI)
🚀 Startup Steps
🔸 Create fullstack-app/particles
🔸 Acquire First Granule: "Database Module L0"
🔸 Save as particles/Database/Database_L0.txt
✅ Completion Mark
▸ 120 Granules Fully Archived
▸ Three Scenario Tests Passed
💎 Additional Notes#
🔎 Granule Identifier: File Header [Module] Level [Number]
🔗 Dependency Declaration: File Tail Annotates Dependency Relationships
🎯 Acceptance Criteria:
▸ 🖥️ Server: All API Responses Normal
▸ 📱 Client: Core Business Process Closed Loop
✨ Operation Mnemonic:
Create Directory → Acquire Granules → Integrate Modules
Connect Systems → Verify Scenarios → Form Projects🔥 Key Tips:
Prioritize completing Database_L1 (System Layer) and Controller_L3 (Security Layer)
Can prevent 80% of integration issues!⏱️ Performance Benchmark:
Server Response < 500ms | Client Load < 1 second🛡️ Security Key Points:
Must Check Database_L3 (TLS Encryption) + Controller_L3 (JWT Authentication)
🚨 Common Mistakes Reminder#
▸ ⚠️ Connection Order Trap
Server Controller must be completed before starting Client DataSource module
Skipping levels will cause compilation errors
▸ ✏️ Version Control Key Points
Update version number after modifying granule files
Key backup nodes: End of Phase 1/3/5
▸ 🔧 Adapter Creation Rules
Only create when interface issues are found during verification phase
Must record adaptation reasons and solutions
🌈 Success Secret:
Strictly follow the 10 module order
Refer to global-adapters case library when encountering issues
Validate immediately after completing each phase!
📋 Final Checklist#
🔍 10 Module Directories Fully Created
🔗 Cross-Module Dependency Relationships Clearly Annotated
🛡️ Security Layer (L3) Double Verification
⚡ Performance Benchmark Testing Standards Met
✅ Three Scenario Business Flow Closed Loop Verification
🎉 Completion Declaration:
When the 10 modules are perfectly integrated, and all three scenario tests are green-lit
Your full stack architecture is ready!
