Next.js Supabase shadcn/ui PWA

Key Principles

• Code Quality & Style

  • Write concise, maintainable, and strongly typed code with accurate TypeScript implementations.
  • Embrace functional, declarative programming. Avoid OOP and classes.
  • Limit files to a maximum of 150 lines; refactor into smaller modules if exceeded.
  • Prefer iteration and modularization over duplication.
  • Use descriptive, semantic variable names with auxiliary verbs (e.g., isLoading, hasError).
  • Use lowercase with dashes for directories and files (e.g., components/auth-wizard).
  • Favor named exports for components.
  • Adopt RORO (Receive an Object, Return an Object) for function parameters/returns.
  • Always attain to use DRY (Don't Repeat Yourself) principles.
  • Conduct regular code reviews and frequent refactoring sessions to ensure consistency and quality.
  • Check and improve Web Vitals (LCP, CLS, FID) to maintain performance and user experience.

• Create 'Build Notes':

  • You must create a 'Build Notes' file for each task group to track the progress of the task group we work on.
  • Clarity & Brevity: Keep notes concise, direct, and focused on the task at hand.
  • Logical Naming: Use a consistent naming convention that ties each notes file to a specific task and date.
  • Incremental Updates: Update notes as plans evolve or tasks are completed. Append rather than overwrite.
  • Traceability: Ensure that each decision or change in approach is recorded and easy to follow.

• Review 'Project Contexts':

  • You must review the projectContext.md as we need to ensure that the project context is up to date and accurate.
  • Stability: Treat context files as stable references, not daily scratchpads.
  • Selective Updates: Update context files only when there are significant, approved changes to requirements or project scope.
  • Accessibility: Make context files easily understandable and organized so future developers can quickly grasp the project’s core guidance.

• Stack and Framework Conventions

  • Target Next.js 15+ and leverage the App Router, React Server Components (RSC), and SSR capabilities.
  • Use Zustand for state management in client components when necessary.
  • Maintain proper Shadcn UI management using npx shadcn@latest add for new components.
  • Follow a mobile-first approach and responsive design patterns.
  • Emphasize server-side logic, minimizing the usage of use client and other client-only APIs.
  • Structure project as Progressive Web App (PWA) with offline capabilities, app-like experience, and installability across devices.

• Monorepo & Tooling

  • If using a monorepo structure, place shared code in a packages/ directory and app-specific code in app/.
  • Use Taskfile.yml commands for development, testing, and deployment tasks.
  • Keep environment variables and sensitive data outside of code and access them through .env files or similar configuration.

Below is a structured guideline to provide to the AI development agent, incorporating key principles and detailed rules for maintaining the /ProjectDocs/Build_Notes/ and /ProjectDocs/contexts/ directories.

Rules for Build Notes Files

1. Location & Naming:

   • Store all notes files in /ProjectDocs/Build_Notes/.
   • Use a logical, descriptive naming convention, e.g., build-title_phase-#_task-group-name.md.
   • Use the `` to describe the build task.
   • Use the `` to apply the Phase # to the build task.
   • Use the `` to describe the task group name.
   • Example: supabase-schema-standardization_phase-1_preparation-and-code-analysis.md
     • supabase-schema-standardization is the build title
     • phase-1 is the phase number
     • preparation-and-code-analysis is the task group name

2. Content Structure:

   • Begin with a brief Task Objective that summarizes what you aim to achieve.
   • Provide Current State Assessment: a short description of the current state of the project pertaining to the build tasks.
   • Provide Future State Goal: a short description of the future state of the project pertaining to the build tasks.
   • Follow with a Implementation Plan: a numbered list of steps containing checklist tasks to achieve the future state.
   • Update the Implementation Plan as tasks are completed and line out not applicable tasks. NEVER DELETE TASKS FROM THE PLAN.
   • If the plan changes or evolves, add new steps or tasks, rather than overwriting previous content.

3. When to Update:

   • At Task Start: Create or open the task-specific notes file and record the initial plan before coding.
   • During Task Execution: Add updates when plans change, difficulties arise, or new insights emerge.
   • At Task Completion: Append a summary of what was done and verify it aligns with the original objective.

4. Style & Tone:

   • Keep notes succinct, on-topic, and free of unrelated commentary.
   • Maintain a logical sequence so that future readers can understand the decision-making process without confusion.

5. Completion of Build Notes:

   • Once the build notes are complete, move the file to the /ProjectDocs/Build_Notes/completed/ directory.
   • If build notes are deprecated and no longer needed, move the file to the /ProjectDocs/Build_Notes/archived/ directory.

---

Rules for Context Files

1. Master Project Context (projectContext.md):

   • Located in /ProjectDocs/contexts/.
   • Provides the overarching project scope, requirements, and design principles.
   • Only update this file if there are major changes to the project’s fundamental direction or scope.

2. Additional Context Files:

   • Supplementary files (e.g., uiContext.md, featureAContext.md) may be created for more detailed specifications on certain functionalities, designs, or areas of the application.
   • Keep these files stable. Update them only when new, approved changes need to be documented.
   • Reference these files frequently to ensure development aligns with established guidelines.

3. Change Management:

   • Record any changes to context files within the corresponding build notes file for that task.
   • Maintain a clear rationale for context changes to preserve transparency and alignment with the core project goals.
