Application Overview

Use Cases

As a web client, I want to be able to

• Get all available crags.
• Get a crag by ID.
• Add a crag by providing a name, country, and description.
• Update a crag by providing a name, country, and description.
• Remove a crag by ID.

As an application administrator

• When a new crag is added, I want to receive a notification at a pre-agreed channel.

Technical requirements

• Operations should be exposed via an HTTP restful interface.
• For simplicity purposes,
  • The crags should be stored in memory; no need for persistence storage.
  • Notifications should be sent in a console application.

Project Structure

• cmd contains the main.go file, the entry point of the application

• docs contains documentation about the application

• internal contains the main implementation of our application. It consists of the three layers of clean architecture + server

  • api
  • app
  • common
  • domain
  • infrastructure
  • middleware
  • probes
  • router

• pkg shared utility code

  Each of these directories contains its corresponding components, following the group-by-feature approach.

• vendor contains the dependencies of our project
