Guide for the Technical Blueprint

The Technical Blueprint is a critical document that outlines the system's architecture, technical details, and workflows, focusing on how AI tools like GitHub Copilot, OpenAI, and Claude will assist in development. This document bridges the conceptual goals from the PSD with the practical implementation in the Task and Implementation Plan.

Purpose of the Technical Blueprint

  • Define the Architecture: Provide a clear map of how the system is structured and interconnected.
  • Guide AI Usage: Specify where and how AI tools will contribute to the development process.
  • Establish Standards: Ensure consistency across components and workflows.
  • Prepare for Challenges: Anticipate technical complexities and propose solutions.

Sections of the Technical Blueprint

  1. System Overview

    • What it includes:
      • A high-level summary of the system architecture (frontend, backend, database, etc.).
      • Visual diagrams to illustrate component relationships.
    • How it aligns:
      • Builds on the goals and features defined in the Product Specification Document (PSD).

  2. Component Breakdown

    • What it includes:
      • A detailed description of each major system component (e.g., widget system, authentication).
      • Roles of AI tools in creating or enhancing these components.
    • How it aligns:
      • Guides the specific tasks in the Task and Implementation Plan.

  3. AI Workflow

    • What it includes:
      • Detailed prompts and interaction strategies for AI tools.
      • Validation steps for AI-generated outputs.
    • How it aligns:
      • Directly informs the use of AI in the Task and Implementation Plan and ensures output quality.

  4. Frameworks and Tools

    • What it includes:
      • The selected frameworks, libraries, and tools (e.g., Bun, React, Tailwind CSS).
      • Rationale for their selection and their role in the architecture.
    • How it aligns:
      • Serves as a checklist during the Code Review and Change Log phase to ensure consistency.

  5. Deployment Plan

    • What it includes:
      • Environment setup and hosting strategies (e.g., Vercel for frontend, Bun for backend).
      • CI/CD pipeline details.
    • How it aligns:
      • Forms the basis for the Release and Deployment Guide.

How the Technical Blueprint Aligns with Other Documents

Section Purpose in Blueprint Connection to Other Documents
System Overview Maps out the architecture. Expands on the project goals and features from the PSD.
Component Breakdown Details each system component. Informs task breakdowns and dependencies in the Task and Implementation Plan.
AI Workflow Specifies AI roles and prompts. Guides interaction with AI in the Task and Implementation Plan and ensures validation during coding.
Frameworks/Tools Defines tools and libraries. Sets standards for code quality and compatibility, referenced in the Code Review and Change Log.
Deployment Plan Outlines environment setup and strategies. Directly informs the Release and Deployment Guide.

How to Populate the Technical Blueprint

Step-by-Step Guide

  1. Define the System Overview

    • Use a diagramming tool (Lucidchart, Draw.io, or Mermaid.js) to map the architecture.
    • Example:
      • Frontend: React + Tailwind CSS (modular components).
      • Backend: Bun server for API logic.
      • Database: SQLite for lightweight storage.

  2. Break Down Components

    • List components and their responsibilities.
    • Example:
      • Widget System: Handles widget rendering and configuration.
      • Authentication: Role-based access control.
    • Assign AI tools for relevant tasks:
      • GitHub Copilot for frontend components.
      • OpenAI for backend API scaffolding.

  3. Document AI Workflows

    • Specify prompts for each task and validation steps.
    • Example Prompt:
      • "Generate a React component for a resizable widget using Tailwind CSS with a drag-and-drop feature."
    • Validation:
      • "Review the generated code for reusability and security vulnerabilities."

  4. Choose Frameworks and Tools

    • Justify the selection of frameworks.
    • Example:
      • Vite: "Chosen for its fast build times and modern JavaScript features."
      • ShadCN UI: "Provides consistent and customizable UI components."

  5. Draft the Deployment Plan

    • Describe the hosting and deployment strategy.
    • Example:
      • Frontend on Vercel.
      • Backend deployed using Bun’s native HTTP server.
      • CI/CD pipeline for automated builds.

Example Technical Blueprint

# Technical Blueprint

## System Overview
- **Frontend:** React, TypeScript, Tailwind CSS, ShadCN UI.
- **Backend:** Bun for server-side logic and API handling.
- **Database:** SQLite for lightweight local storage.
- **Diagram:** ![Insert architecture diagram here]

## Component Breakdown
1. **Widget System**:
   - **Description:** Allows users to add, resize, and configure widgets.
   - **AI Contribution:** Copilot for component generation, OpenAI for API logic.
2. **Authentication**:
   - **Description:** Implements role-based access control.
   - **AI Contribution:** OpenAI for backend endpoints.
3. **Dashboard Layout**:
   - **Description:** Provides a responsive and customizable UI.
   - **AI Contribution:** GitHub Copilot for Tailwind-based components.

## AI Workflow
1. **Prompts for Copilot**:
   - Example: *"Create a responsive navbar in React using Tailwind CSS."*
2. **Validation Steps**:
   - Review AI-generated code for accessibility and performance.
   - Use Claude for code explanation and optimization.

## Frameworks and Tools
- **Frontend**:

How the Technical Blueprint Makes Implementation Easier

  1. Clear Roadmap: Provides a visual and detailed guide for building the application, ensuring alignment with project goals from the PSD.
  2. Efficient Use of AI: Offers specific prompts and workflows to maximize AI tool contributions.
  3. Scalability: Ensures the architecture and tools can handle future expansions, linking to potential updates in the Task Plan or Release Guide.
