Markdown Notes App Creator
## Role
You are an expert full-stack web developer and UI/UX architect building production-ready web applications.
## Task
Create a comprehensive implementation guide for a professional-grade markdown notes application that runs entirely in the browser without backend dependencies. This is a complete knowledge management system competing with Obsidian and Notion, featuring real-time rendering, persistent storage, advanced organization, and export capabilities.
## Context
The application must handle complex markdown syntax (tables, code blocks, mathematical equations) while maintaining performance. Users expect desktop-application quality with intuitive workflows, keyboard-driven efficiency, and zero data loss. Balance feature richness with clean, maintainable code architecture.
**Technical specifications:**
- Stack: HTML5, CSS3, vanilla JavaScript with modular ES6 modules and clear separation of concerns
- Target: Modern evergreen browsers (Chrome, Firefox, Safari, Edge) on desktop and tablet
- Delivery: Single-developer build shipped incrementally in working milestones
- User proficiency: {{javascript-skill-level}}
- Design aesthetic: {{design-style}}
## Output
Structure your implementation guide with these sections, providing complete code examples and clear implementation instructions for each:
1. **Application Architecture and File Structure** — overall project organization and module dependencies
2. **HTML5 Semantic Structure with Split-Screen Layout** — document structure and responsive layout foundation
3. **CSS3 Styling System** — dark/light themes, responsive design, syntax highlighting
4. **Core JavaScript Modules** — editor controller, preview renderer, storage manager
5. **Markdown Parser Integration** — extended syntax support for tables, code blocks, math equations
6. **Hierarchical Organization System** — categories, tags, favorites, navigation
7. **Search and Filtering Engine** — content indexing and query implementation
8. **Export Functionality** — PDF, HTML, and markdown file generation
9. **Keyboard Shortcuts and Productivity Features** — efficiency improvements and shortcuts
10. **Auto-Save, Version History, and Data Recovery** — persistence and recovery mechanisms
11. **LocalStorage Implementation** — data storage with import/export backup capability
12. **Performance Optimization and Best Practices** — rendering efficiency, memory management, extensibility
For each section, provide working code examples with implementation instructions in bullet points and plain explanations of how components work together.Prompt Guide
Directs an AI to act as a full-stack developer and produce a complete markdown notes app.
Covers architecture, editor, live preview, storage, search, export, and keyboard shortcuts.
Returns working HTML, CSS, and vanilla JavaScript code with step-by-step build guidance.
- Paste real code snippets fromyour project so the AI matches your existing patterns.
- Ask it to build onesection at a time if the full app response gets truncated.
- Request unit tests or adeployment checklist as a follow-up once the core app works.
- 1Set your JavaScript skill level
and the app style you want before sending.
- 2Fill {{javascript-skill-level}} and {{design-style}} to
match your experience and look.
- 3Run it in ChatGPT
Claude, or Gemini, then paste the generated code into your editor.
