## What it does

Drop the file into Cursor as a rule and it lays out how the project should be written. Mobile screens come first, then larger ones, with Tailwind's responsive prefixes (`sm:`, `md:`, `lg:`, `xl:`) doing the scaling. A design system with shared colors, typography and spacing lives in `tailwind.config.js` as custom tokens. Accessibility gets its own section: contrast ratios, semantic HTML, ARIA where needed, keyboard navigation.

On performance the rule points to `React.lazy()` and `Suspense` for code-splitting, `react-window` for long lists, and image optimization. Firebase guidance covers security rules, the SDK's offline persistence, and queries that keep read/write operations low. Forms go through Formik or `react-hook-form` with validation and clear error messages. Interactive elements should be at least 44x44 pixels so they are easy to tap.

One line stands out: when creating a file, don't conflict it with existing `.tsx` and `.jsx` files. That assumes your project already carries both, so check your folder structure before you commit to this rule. The file also ends with a ready-made prompt for a language model about a pill-tracking feature with monthly adherence reports. It has nothing to do with your app, but it shows how the author frames requests.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/tailwind-react-firebase-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/tailwind-react-firebase-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/tailwind-react-firebase-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/tailwind-react-firebase-cursorrules-prompt-file.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/tailwind-react-firebase-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/tailwind-react-firebase-cursorrules-prompt-file.mdc

## When to use it
- set one set of layout conventions for a Tailwind and React project
- audit contrast, keyboard access and semantic markup
- split the bundle with `React.lazy()` and `Suspense`
- wire up Firebase security rules and offline persistence
- pick a form library and validation approach

## Example prompts
- Check my component against the rules in `.cursor/rules/tailwind-react-firebase-cursorrules-prompt-file.mdc`
- Build this product card mobile-first, the way the rule describes
- Rewrite this list to use virtualization with `react-window`

Here are some best practices and rules to follow for creating a high-quality, mobile-first web app with excellent UI/UX using Tailwind, React, and Firebase:

Mobile-First Design:
Always design and implement for mobile screens first, then scale up to larger screens.
Use Tailwind's responsive prefixes (sm:, md:, lg:, xl:) to adjust layouts for different screen sizes.

Consistent Design System:
Create a design system with consistent colors, typography, spacing, and component styles.
Utilize Tailwind's configuration file (tailwind.config.js) to define your custom design tokens.

Performance Optimization:
Use React.lazy() and Suspense for code-splitting and lazy-loading components.
Implement virtualization for long lists using libraries like react-window.
Optimize images and use next/image for automatic image optimization in Next.js.

Responsive Typography:
Use Tailwind's text utilities with responsive prefixes to adjust font sizes across different screens.
Consider using a fluid typography system for seamless scaling.

Accessibility:
Ensure proper color contrast ratios using Tailwind's text-* and bg-* classes.
Use semantic HTML elements and ARIA attributes where necessary.
Implement keyboard navigation support.

Touch-Friendly UI:
Make interactive elements (buttons, links) at least 44x44 pixels for easy tapping.
Implement touch gestures for common actions (swipe, pinch-to-zoom) where appropriate.

WHEN CREATING A FILE DON'T CONFLICT IT WITH .TSX AND .JSX FILES

Firebase Best Practices:
Implement proper security rules in Firebase.
Use Firebase SDK's offline persistence for better performance and offline support.
Optimize queries to minimize read/write operations.

Error Handling and Feedback:
Implement proper error boundaries in React.
Provide clear feedback for user actions (loading states, success/error messages).

Animation and Transitions:
Use subtle animations to enhance UX (e.g., page transitions, micro-interactions).
Utilize Tailwind's transition utilities or consider libraries like Framer Motion.

Form Handling:
Use libraries like Formik or react-hook-form for efficient form management.
Implement proper form validation with clear error messages.

Code Organization:
Follow a consistent folder structure (e.g., components, hooks, pages, services).
Use custom hooks to encapsulate and reuse logic.

Native-like Features:
Implement pull-to-refresh for content updates.
Use smooth scrolling and momentum scrolling.
Consider using libraries like react-spring for physics-based animations.

Here’s a concise prompt for a language model to help you with the logic for creating AI-powered medication insights in your app:

Prompt:
Design a feature for a pill management app that tracks user interactions with medications (Take/Skip) and generates monthly adherence reports.

The app should:
