Building a Go Web Server from scratch.

A web server is just a computer that serves data over a network, typically the Internet.

Servers run software that listens for incoming requests from clients. When a request is received, the server responds with the requested data.

Brief explanation of the key points from the graph above:

• Client: Initiates the HTTP request.
• Server: Handles the incoming HTTP request.
• Router: Directs the request to the appropriate controller.
• Controller: Processes the request and interacts with the service layer.
• Service: Manages business logic, interacts with storage, and handles authentication/authorization.
• Storage: Consists of a database and cache for storing data.
• Auth Service:
  • Login: Manages user login.
  • Token: Handles token creation and verification.
• Authentication: Verifies user credentials.
• Authorization: Checks user permissions.
• Webhooks: Manages webhooks and sends data to external services.
• External Service: Receives data from webhooks.
