🧩 Common Library

The Common Lib is not a standalone microservice. It is a shared dependency imported by other microservices in the CoderRide ecosystem.

🔑 Key Responsibilities

• Code Reusability: Prevents duplicating standard classes (like JwtUtil or ErrorResponse) across 10 different microservices.
• Consistency: Ensures all services handle exceptions and API responses in the exact same format using GlobalExceptionHandler.
• Inter-service Communication: Houses the DTOs used when services talk to each other.

⚙️ Usage

Since this is a library, it doesn't run on a port. It is built using Maven and included in the pom.xml of other services like this:

<dependency>
    <groupId>com.codingclub</groupId>
    <artifactId>common-lib</artifactId>
    <version>1.0.0</version>
</dependency>
