{{ Project or Feature Name }} – Technical Design Document

Introduction

Purpose:
Explain why this document exists — what is being designed or improved.

Scope:
Define the scope: architecture, modules, and affected components.


System Overview

High-Level Description:
Provide a summary of the system or feature, its purpose, and primary functions.


Architecture

System Architecture:
Explain the architecture diagram — show the components and data flow.

Technology Stack:
List languages, frameworks, and tools used (e.g., .NET, Node.js, PostgreSQL, Kafka).

External Dependencies:
List external APIs, services, or third-party systems integrated.


Key Components

Component 1 – Name

  • Purpose:
  • Responsibilities:
  • Interactions:
  • Data Flow:

Component 2 – Name

(Repeat for each key module or service)


Detailed Design

Database Design:
Describe data models, relationships, and schemas. Include ER diagrams if available.

Algorithms and Logic:
Summarize key logic, workflows, and algorithms.

Security Considerations:
Authentication, authorization, encryption, data privacy.


User Interface (if applicable)

Design Overview:
Provide mockups, wireframes, or UX flows.

💡 If frontend components are affected, remember to create a frontend issue.


Integration and Interfaces

External Interfaces:
List and describe APIs or systems this feature interacts with.

Internal Interfaces:
Document service-to-service communication and data formats.


Deployment and Infrastructure

Cloud Deployment

Describe changes to Appcircle Helm charts or cluster configuration.

📌 Open a Helm issue if environment changes are required.

Self-Hosted Deployment

Specify changes affecting Docker Compose or installation scripts.

📌 Open a self-hosted script issue if necessary.

💡 If this development affects customer behavior, create a documentation issue.


Testing and Quality Assurance

Test Strategy:
Unit, integration, end-to-end, and regression testing.

Quality Assurance:
Code review, linting, CI/CD pipelines, release gates.


Performance Considerations

Requirements:
Response time, concurrency limits, throughput.

Optimizations:
Caching, connection pooling, async processing, scaling strategies.


Maintenance and Support

Monitoring and Logging:
Detail metrics, tracing, alerting, and log aggregation (e.g., Prometheus, Loki).

Support and Maintenance:
Ongoing patching, upgrades, and post-release monitoring.


Risks and Mitigation Strategies

List major technical, operational, or security risks with mitigation steps.


Appendix

Add diagrams, UML, flowcharts, and additional context.
