# Bomb Project Vision Statement

> **"Making complex scenario solution design as elegant as building blocks"**

## 🌈 Core Positioning
A sandbox of SpringBoot/SpringCloud ecosystem best practices for developers. Each component serves both as an independently runnable scaffold and a combinable business puzzle piece. Through real-scenario-driven pattern accumulation, we eliminate cognitive gaps in distributed system design.

## 🛠️ Functional Traits
- **Modular Clarity**  
  Each SpringCloud component stands independently - from registry centers to distributed transactions, all launchable with one Boot command

- **Pattern Museum**  
  Provides elegantly abstracted solutions for high-frequency scenarios (idempotency control/circuit breaking/tracing, etc.)

- **Scenario-Driven Development**  
  The issues section becomes a **requirement marketplace**, where real business pain points evolve into complete specimens: `requirement card -> design blueprint -> code implementation`, each module containing corresponding README

- **Living Documentation**
  ### 💡 Understanding "Living Documentation"
  Each technical solution grows like a decision tree:
    1. Visualizing technical selection paths with `decision tree diagrams`:
       ```mermaid
       graph TD
           A[Need config center?] -->|Yes| B{Production?}
           B -->|Yes| C[Nacos Cluster]
           B -->|No| D[Local File Mock]
           A -->|No| E[Skip Config Center]
       ```
    2. Marking key decisions with `// @choice` code annotations:
       ```java
       @Bean
       // @choice Configuration Center Options: 
       // - Option1: Local config (dev)
       // - Option2: Nacos (prod)
       public ConfigService configService() {
           if (env.equals("prod")) {
               return new NacosConfigService(); // Production choice
           } else {
               return new LocalConfigService(); // Development choice
           }
       }
       ```
       Documentation evolves with code updates, maintaining vitality

## 🌟 Collaborative Vision
Aim to become:
- **Pitfall Survival Guide** for newcomers: Understand component essence with minimal effort, avoid configuration hell
- **Inspiration Sandbox** for veterans: Validate architectural hypotheses in reproducible scenarios
- **Pattern Encyclopedia** for teams:

  ### 🧩 What is "Pattern Encyclopedia"?
  When PM says: "We need gray release functionality"
  
    1. **Instant Solution Location**:
        - Search `gray-release` tag in project
        - Locate corresponding `gateway-gray` module

    2. **Ready-to-Use Paradigm**:
       ```yaml
       # Gray rules example
       gray-rules:
         - condition: header['User-Type'] == 'VIP'
           target: v2-service
         - condition: ip in 192.168.1.*
           target: v2-service
       ```

    3. **Core Code Demonstration**:
       ```java
       @Component
       public class GrayRouteFilter implements GatewayFilter {
           @Override
           public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
               // Get user type from header
               String userType = exchange.getRequest().getHeaders().getFirst("User-Type");
               
               // @choice Routing strategies:
               // - OptionA: Metadata tagging
               // - OptionB: Direct instance redirection
               if ("VIP".equals(userType)) {
                   exchange.getAttributes().put(GRAY_FLAG, "v2-service"); 
               }
               return chain.filter(exchange);
           }
       }
       ```
       Contains: config templates, code samples, solution comparisons - integrable in 5 minutes

> We don't build monolithic scaffolds, but forge a master key to SpringBoot/SpringCloud. When debugging Feign timeouts at midnight, there's always a working example lighting your way.
