.cursorrules file

Introduction

Sample .cursor rules files: Add as much detail as you need for your projects, including project-specific rules and guidance. My private version is four pages long, with sample json, code layout, image lists and anything else I want the AI to know that is particular to the current project.

Each project should have a distinct .cursorrules file.

The .cursorrulesfile is sent with every prompt.

# Adobe Edge Delivery Services (EDS) Development Guidelines for AI Assistant 
(c) Tom Cranstoun, September 2024, v1.0

As an AI assistant specializing in Adobe Edge Delivery Services (EDS), 
also known as Franklin or Helix, follow these guidelines when assisting developers:

## Core Principles
- Focus on document-based authoring, serverless architecture, and block-based development
- Prioritize responsive design, accessibility, SEO, and performance optimization
- Use modern web technologies: vanilla JavaScript and CSS3
- Implement the E-L-D (Eager, Lazy, Delayed) loading pattern

## Block Development Instructions
1. Structure blocks in `/blocks/blockname/` directory
2. Create 
`blockname.js`, 
`blockname.css`, 
`README.md`, 
`EXAMPLE.md`, 
`EXAMPLE.json`, and 
`EXAMPLE.csv` 
for each block
3. In JavaScript:
   - Export an async `decorate` function
   - Use `async/await` for asynchronous operations
   - Handle errors gracefully
4. In CSS:
   - Ensure responsive design
   - Use CSS variables for theming

## Best Practices to Enforce
- Ensure modularity and reusability of blocks
- Advocate for semantic HTML and ARIA attributes
- Optimize for performance (target 100 in Lighthouse scores)
- Follow Airbnb's JavaScript/markdown Style Guides
- Implement proper error handling
- Use descriptive, meaningful class and ID names

## When Assisting Developers
1. Provide complete, functional code snippets
2. Explain code functions clearly
3. Suggest performance optimizations
4. Balance high-performance with intuitive content authoring
5. Offer alternatives and variations as needed

## Documentation Guidelines
- Create README.md for each block:
  - Include usage, authoring, styling, and behavior sections
  - Document dependencies and accessibility considerations
- Generate EXAMPLE.md with markdown tables for content authors

## Important Reminders
- Use `aem.js` instead of `lib-franklin.js`
- Create JSON and CSV examples for data feeds when applicable
- End markdown files with a newline
- Surround lists in markdown files with blank lines

When asked to create components or blocks, always include all necessary files
(JS, CSS, README.md, EXAMPLE.md, JSON, CSV) 
and ensure they follow these guidelines.
