by SD Solar 52 views

Hey guys! Let's dive into something super important: creating architecture documentation for Flakeradar. This isn't just some stuffy task; it's about making our lives easier as contributors and making sure Flakeradar rocks. This detailed documentation acts as a roadmap for understanding the system's design, how data flows, and how different components interact with each other. It's like having a secret weapon for anyone looking to jump in and contribute to the project. This guide aims to clearly define the need for, and the components of, robust architecture documentation, ensuring that every contributor can easily understand the system and contribute effectively. This documentation isn't just helpful; it's essential for anyone looking to navigate the complexities of our system.

The 'Why' Behind the Architecture Docs

So, why are we even bothering with this, right? Well, imagine trying to build something without a blueprint. That's essentially what it's like to contribute code without knowing the system's architecture. Architecture documentation is the blueprint for our code. It allows contributors to understand the system and make meaningful contributions. It's like a compass that helps you find your way around the codebase and understand how everything fits together. It's all about making sure that every contributor, new or old, can understand the system’s design, data flow, and component interactions before they even start writing code. Without this, we risk creating a fragmented, hard-to-maintain system. This is what we aim to solve. It ensures that everyone is on the same page, helping us avoid common pitfalls.

User Need & Problem Statement: The Contributor's Perspective

As a contributor,

I want to have detailed architecture documentation,

So that I can understand the system design, data flow, and component interactions before contributing code.

This simple statement captures the core need. Without detailed documentation, understanding how components interact and where changes fit in the larger system is tough. Detailed architecture documentation acts as a vital tool, especially for new contributors. It provides a quick way to get up to speed on the system's design. This leads to faster onboarding, fewer bugs, and more effective contributions.

Context: The Bigger Picture

Contributors need to understand the system architecture to make meaningful contributions. Detailed architecture documentation helps them understand how components interact and where their changes fit in the larger system. This is a crucial element for maintaining the integrity and usability of our software.

Acceptance Criteria: What Success Looks Like

Let's break down what we need to make these docs a reality. The acceptance criteria act as our checklist, ensuring we've hit the mark. These criteria act as a litmus test for the documentation. If the docs meet the criteria, they serve their intended purpose.

Scenario 1: System Understanding

  • Given a contributor wants to understand the system architecture.
  • When they read the architecture documentation.
  • Then they can understand the major components and their interactions.

This scenario focuses on the fundamental goal: easy system comprehension. The documentation should provide a clear, concise overview of the core components. It should explain how they interact, and how data flows through the system. This allows contributors to grasp the big picture.

Scenario 2: Contribution Guidance

  • Given a contributor wants to make a change.
  • When they consult the architecture documentation.
  • Then they understand how their change fits into the system.

This is all about making it easier to contribute. The documentation needs to show how any changes fit within the overall system. If it's easy to see how a change impacts other parts of the system, it will be much easier to avoid conflicts. It helps contributors see how their work aligns with the overall vision of the project.

Additional Criteria: The Checklist

  • [x] System context diagram (C4 Level 1)
  • [x] Container diagram (C4 Level 2)
  • [x] Component diagrams for key services
  • [x] Data model with ERD
  • [x] Sequence diagrams for critical flows
  • [x] Technology stack and rationale
  • [x] Deployment architecture
  • [x] ADR (Architecture Decision Records) index

This list is a comprehensive outline of the essential elements. Each element adds value to the architecture documentation.

Non-Functional Requirements: Making it Usable

Let's not forget how important the usability and maintainability are. It's not enough to simply have documentation; it needs to be clear, complete, and easy to maintain.

  • [x] Clarity: Diagrams are clear and well-labeled. Making sure that anyone can easily understand the diagrams.
  • [x] Completeness: All major components documented. The documentation needs to be comprehensive.
  • [x] Maintainability: Diagrams in version control. The ability to easily update and change the diagrams.
  • [x] Accessibility: Text alternatives for diagrams. Ensuring that it is accessible to everyone.

Technical Implementation Notes: The How-To

Technical Approach: The Tools

  • Use Mermaid for diagrams in Markdown
  • Keep diagrams in sync with code
  • Document architectural decisions as ADRs
  • Include rationale for technology choices
  • Provide contribution guidelines

This is the practical side. We're going to use Mermaid. We'll use this tool to generate diagrams right in our markdown files. This will make it easier to maintain the diagrams and keep them up-to-date with our codebase. It outlines the core methods we'll be using.

API & Database Changes: Keeping it Simple

  • API Changes: None
  • Database Changes: None

No breaking changes here! It's focused on creating documentation. Our goal is to make it easy for everyone to understand the system. So, we're keeping it simple and focusing on the core requirement.

Dependencies: What We Need

  • Mermaid for diagram generation
  • Architecture Decision Record process

These are the tools and processes we'll need to create and maintain our architecture documentation. These dependencies are essential.

Test Scenarios: Checking Our Work

How do we make sure our documentation is up to snuff? These test scenarios are essential to ensuring that our documentation meets all the requirements.

Manual Test Scenarios: Human Review

  1. Review architecture diagrams for clarity
  2. Verify component interaction descriptions
  3. Check technology stack documentation
  4. Validate ADR index completeness

These manual tests will help ensure the quality of the documentation. They will ensure that our documentation is easy to read and understand.

Automated Tests: Not Applicable (for now)

  • None (documentation)

Additional Notes: The Big Picture

This documentation is essential for onboarding new contributors and maintaining architectural consistency. Clear documentation is like a shared language. It helps everyone understand the system, improving collaboration and code quality.
