# nextjs-vercel-supabase-cursorrules-prompt-file Configures Cursor for building the BA Copilot app with Next.js App Router, Vercel AI, Supabase, and bpmn-js. Keeps the AI aligned with the chosen stack. - rule · `type=rule` · Cursor · ★ 41024 - Author: PatrickJS - License: CC0-1.0 · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/nextjs-vercel-supabase-cursorrules-prompt-file.mdc - Updated: 2026-05-30 - HTML: https://affpapa.org/en/nevibecode/rules/nextjs-vercel-supabase-cursorrules-prompt-file ## What it does This rule sets project specifications and architectural constraints for BA Copilot, an assistant for business analysts. The application pairs a chatbot interface with interactive BPMN diagram rendering via `bpmn-js`, handling PDF handbook uploads and process flowcharts. The core requirement is enforcing Next.js App Router. The prompt explicitly instructs the assistant never to suggest Pages Router code. The defined stack includes Supabase for database types and authentication, TanStack Query, Vercel AI, and Material UI, with Orval noted for API typing and MSW testing. Because the prompt notes the author is new to Next.js while intermediate in React, strict App Router compliance prevents broken directory conventions. ## Requirements - Works with: Supabase ## Install ### Cursor (native platform) **Manually: put the files in place** - File: `.cursor/rules/nextjs-vercel-supabase-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply ### Claude Code **Manually: put the files in place** - File: `.claude/rules/nextjs-vercel-supabase-cursorrules-prompt-file.md` — The paths frontmatter field limits the files: move globs from the source into paths ### Codex **AGENTS.md** - Codex reads AGENTS.md: paste the rule text there ### GitHub Copilot **Manually: put the files in place** - File: `.github/instructions/nextjs-vercel-supabase-cursorrules-prompt-file.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/rules/nextjs-vercel-supabase-cursorrules-prompt-file.md` ### Cline **Manually: put the files in place** - File: `.clinerules/nextjs-vercel-supabase-cursorrules-prompt-file.md` Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/nextjs-vercel-supabase-cursorrules-prompt-file.mdc ## When to use it - prevent suggestions using legacy Next.js Pages Router - wire Supabase typed database and authentication into TanStack Query - integrate `bpmn-js` for interactive process diagram editing in Material UI - handle document uploads such as PDFs for Vercel AI context analysis ## Example prompts - Build a Next.js App Router page that embeds `bpmn-js` diagram viewer - Set up a typed Supabase query using TanStack Query - Create an upload component for PDF process documents using Material UI ## Source text · nextjs-vercel-supabase-cursorrules-prompt-file.mdc · CC0-1.0 Below is the content of a third-party file.

I will sometimes refer to it as bacp. ## BA Copilot MVP ### Overview It is an assistant for business analysts. The MVP will be a an ai chatbot type tool, which will render BPMN diagrams using bpmn-js. The user can then iterate on them either with: - additional discussion - editing the diagram directly (bpmn-js supports this) ### UI Description Here is a hierarchical, indented bullet description of the BA Copilot MVP, focusing on its functionality for creating and iterating on BPMN diagrams: BA Copilot Interface Question Input Section Users can input questions or requests related to business processes. Example: "Based on the doc content what have I missed?" Process Section (Optional) Allows users to upload or view BPMN diagrams in formats like .png, .vsdx, etc. Users can visualize and edit existing diagrams or create new ones. Example: A BPMN diagram showing a flow of "Register expense report", "Approve", and "Deny" processes. Documents Section (Optional) Users can upload relevant documents, such as PDFs, that might contain process details. Example: "Shelter - employee handbook.pdf" uploaded to provide context for the BPMN diagram. Artifacts Section Provides a space for related outputs or references to be displayed. Example: Diagram suggestions based on uploaded content. Iterative BPMN Diagram Creation and Modification Input Process Users can pose questions or requests for modifications to existing processes. Example: Asking for missing steps in the process based on document content. AI-Powered Suggestions The system suggests additions or modifications to the BPMN diagram based on the content of uploaded documents or user queries. Example: Suggestion to add a task for checking the expense policy, citing specific sections from the uploaded handbook. Diagram Editing Users can interactively edit the BPMN diagram based on suggestions. Example: Adding a task "Check expense policy" with inputs and outputs like "Expense report" and "Checked expense report". Documentation and References The system references uploaded documents and highlights relevant sections. Example: Citing "Section 7. Claiming reimbursement for payments made on behalf of the company" from the employee handbook. User Workflow Start with a Question User initiates the process by asking a question or making a request. Upload Process Diagrams and Documents User uploads existing diagrams and documents for context. Receive AI-Generated Suggestions System provides suggestions to enhance or correct the process flow. Modify BPMN Diagram User edits the BPMN diagram based on the received suggestions. Iterate Until Satisfied User continues to ask follow-up questions and modify the diagram until the desired outcome is achieved. This BA Copilot MVP allows users to efficiently create, modify, and iterate on BPMN diagrams with contextual suggestions, leveraging uploaded documents and user queries. ## BA Copilot Vision ### Overview ``` END THIRD-PARTY FILE 33c37c6864840995 The third-party file has ended.
