Next.js + Supabase + Shadcn + PWA development rules with TypeScript, RSC, and build tracking.
What is nextjs supabase shadcn pwa?
Comprehensive Cursor rules for building modern Progressive Web Apps with Next.js 15+, Supabase, and Shadcn UI. Enforces functional TypeScript code, server-side-first architecture, strict file size limits, and structured build documentation via Build Notes and Project Context files.
- Enforce Next.js 15+ App Router, React Server Components, and SSR best practices with minimal client-side code
- Require TypeScript, functional programming, and 150-line file limits with DRY principles and semantic naming
- Mandate Build Notes tracking in `/ProjectDocs/Build_Notes/` with phase/task structure and incremental updates
- Require Project Context review and maintenance in `/ProjectDocs/contexts/` for stable, approved changes only
- Structure projects as PWAs with offline capabilities, installability, and mobile-first responsive design
- Use Zustand for client state, Shadcn UI components via `npx shadcn@latest add`, and Taskfile.yml for CI/CD tasks

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.mdas 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.
- You must review the
-
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 addfor new components. - Follow a mobile-first approach and responsive design patterns.
- Emphasize server-side logic, minimizing the usage of
use clientand 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 inapp/. - Use
Taskfile.ymlcommands for development, testing, and deployment tasks. - Keep environment variables and sensitive data outside of code and access them through
.envfiles or similar configuration.
- If using a monorepo structure, place shared code in a
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
-
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
<build-title>to describe the build task. - Use the
<phase-#>to apply the Phase # to the build task. - Use the
<task-group-name>to describe the task group name. - Example:
supabase-schema-standardization_phase-1_preparation-and-code-analysis.mdsupabase-schema-standardizationis the build titlephase-1is the phase numberpreparation-and-code-analysisis the task group name
- Store all notes files in
-
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.
-
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.
-
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.
-
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.
- Once the build notes are complete, move the file to the
Rules for Context Files
-
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.
- Located in
-
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.
- Supplementary files (e.g.,
-
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.
