main.go

This Go file serves as the main entry point for the application. Here's an overview of its functionality:

1. Imports: The file imports necessary packages from the standard library and various project packages.

2. Variables: It declares a variable exitCode to hold the exit status of the program.

3. Main Function: The main function is where the program execution begins. It sets up defer statements, command-line flags, and handles various signals.

4. Flag Parsing: It parses command-line flags using the pflag package to handle options like help, version, and CPU profiling.

5. Initialization: The program initializes configuration, logging, and other components necessary for its operation.

6. Profiling: If the cpuprofile flag is provided, the program starts CPU profiling and writes the profile data to the specified file.

7. Server Startup: It initializes and starts the HTTP server in a separate goroutine.

8. Signal Handling: The program listens for SIGINT and SIGTERM signals to gracefully shut down the server and exit.

9. Error Handling: It recovers from panics, logs errors, and handles any fatal errors encountered during execution.

Example:

To modify the behavior of the program, you can add or remove command-line flags, adjust initialization parameters, or integrate additional functionality within the main function. For instance, you could enhance logging, add support for different configuration sources, or introduce additional server endpoints.
