Awesome Cursor Rules Collection

Typescript/JS Conventions:
- Use npm for package management
- Use arrow function syntax (const name = () => {}) instead of function declarations
- Use ES6+ import syntax instead of require()
- Project uses React Router v6
- Omit comments in code

Testing Conventions:
- Use given/when/then pattern in test blocks
- Example test structure:
  it('test description', () => {
    // given
    // setup and mock declarations

    // when
    // action being tested

    // then
    // assertions
  }); 

General Guidelines:
- Be concise and accurate, avoid unnecessary verbosity.
- Suggest solutions the user might not have thought about; anticipate needs.
- Treat the user as an expert; provide answers directly and thoroughly.
- Value good arguments over authority; source is irrelevant unless explicitly asked.
- Discuss safety only when it’s crucial and non-obvious.
- Split responses into multiple messages if the content exceeds length limitations.
- Avoid placeholders, TODOs, or incomplete pieces of code; ensure completeness.
- Fully implement all requested functionality. Verify correctness thoroughly.
- Keep README.md up-to-date with project setup and contribution guidelines.
- Confirm before writing code when clarification is required.
- Flag speculative or predictive content.


Code Style and Structure:
- Write concise, technical TypeScript code with accurate examples.
- Use functions declared with the `function` keyword for pure functions; omit semicolons.
- Follow DRY principles (Don’t Repeat Yourself) and prefer modularization.
- Use descriptive variable names with auxiliary verbs (e.g., `isLoading`, `hasError`).
- Never use `export default` unless it’s a config file that doesn’t allow named exports.
- One React component per file; break large components into smaller pieces.
- Use `React.memo()` for performance optimization when appropriate.
- Prefer `async/await` over `.then()` for asynchronous operations.
- Always Receive an Object, Return an Object (RORO).
- Handle errors gracefully; if a promise doesn’t throw, append `noError` to the variable name.



Project Structure:
- **Monorepo Layout**:
  - Deployable apps: `apps/*` (e.g., `apps/blog`, `apps/www`, `apps/api`).
  - Shared modules: `packages/*`.
  - Config files and tooling: `tooling/*`.
- **Naming Conventions**:
  - Booleans: Use auxiliary verbs such as `does`, `has`, `is`, `should` (e.g., `isDisabled`, `hasError`).
  - Directories: Use lowercase with dash separators (e.g., `components/auth-wizard`).
  - React component files: Match the component name (e.g., `CopyRight.tsx` for the `CopyRight` component).
  - File extensions: Use `.config.ts`, `.test.ts`, `.context.tsx`, `.type.ts`, `.hook.ts` appropriately.

React and Next.js Guidelines:

- **React Best Practices**:
  - Minimize `use client`, `useEffect`, and `setState` usage.
  - Favor React Server Components (RSC).
  - Wrap client components in `Suspense` with a fallback.
  - Use dynamic imports for non-critical components.
  - Optimize images (WebP format, size data, lazy loading).
  - Implement accessibility features (e.g., `aria-label`, `tabindex`, proper roles).

- **Next.js Best Practices**:
  - Follow Next.js documentation for Data Fetching, Rendering, and Routing.
  - Optimize Web Vitals (LCP, CLS, FID).
  - Use `nuqs` for URL search parameter state management.
  - Sanitize user inputs to prevent XSS attacks.

Error Handling and Validation:
- Prioritize error handling and edge cases:
  - Handle errors at the beginning of functions.
  - Use guard clauses to handle preconditions and invalid states early.
  - Use early returns for error conditions; avoid deeply nested `if` statements.
  - Avoid unnecessary `else` statements; use the `if-return` pattern.
- Implement global error boundaries to catch and handle unexpected errors.
- Log errors consistently and provide user-friendly error messages.
- Consider using custom error types or error factories.
- Add environment variables to `packages/env` for validation.

Styling and Design:
- Use ShadCN UI, Radix, and TailwindCSS for components and styling.
- Implement responsive design with a mobile-first approach.
- Always use Tailwind classes for styling; avoid inline styles or separate CSS files.
- Utilize the Class Variance Authority (CVA) for managing component variants.

Object-Oriented Programming:
- Use `public` modifier for all public methods.
- Use `private` modifier for all private methods, prefixed with an underscore.
- Place getters and setters at the top of the class.
- Use `static` for static methods.
- Use `async` for asynchronous class methods.

Testing:
- Write unit tests for components using `vitest`.
- Implement integration tests for critical user flows.
- Use snapshot testing sparingly.
- Use Playwright for end-to-end (e2e) tests.



Miscellaneous:
- Sanitize content when using `dangerouslySetInnerHTML`; avoid whenever possible.
- Use libraries like `react-intl` or `next-i18next` for internationalization (i18n).
- Follow Taskfile commands for development and deployment tasks.
- Follow WCAG standards for color contrast and readability.
- Comment only when necessary to clarify complex logic; avoid excessive comments.
- Use JSDoc comments for functions and components to improve IDE intellisense.

- Ensure code is complete! Verify thoroughly finalised.
- Include all required imports, and ensure proper naming of key components.
- Be concise Minimize any other prose.
- If you think there might not be a correct answer, you say so.
- If you do not know the answer, say so, instead of guessing.

### Coding Environment

The user asks questions about the following coding languages:

- ReactJS
- NextJS
- JavaScript
- TypeScript
- TailwindCSS
- HTML
- CSS

### Code Implementation Guidelines

Follow these rules when you write code:

- Use early returns whenever possible to make the code more readable.
- Always use Tailwind classes for styling HTML elements; avoid using CSS or tags.
- Use “class:” instead of the tertiary operator in class tags whenever possible.
- Use descriptive variable and function/const names. Also, event functions should be named with a “handle” prefix, like “handleClick” for onClick and “handleKeyDown” for onKeyDown.
- Implement accessibility features on elements. For example, a tag should have a tabindex=“0”, aria-label, on:click, and on:keydown, and similar attributes.
- Use consts instead of functions, for example, “const toggle = () =>”. Also, define a type if possible.
- Do not dete comments in any case.
- Do not delete extra code from the files.

# Music Visualization Shader Requirements

## Overview

These shaders are used to create real-time music visualizations that control LED lights through screen scraping. The goal is to create engaging, psychedelic patterns that react meaningfully to music while avoiding too many visual dead zones (solid black or white areas).

## Core Requirements

### Visual Quality

- Create intricate, evolving fractal-like patterns
- Maintain constant visual interest across the entire screen
- Avoid large areas of solid black or white
- Make the movement aesthetic and artistic, like something you'd see in an interactive art museum
- Must maintain clear foreground/background separation
- Can use SDF functions for depth and dimensionality
- Can have clear visual hierarchy with rim lighting or edge effects
- Can incorporate ripple and wave effects that dissipate naturally.
  - You can use getLastFrameColor() function to get the color of a given pixel of the last frame to do ripple effects and others.

### Audio Reactivity

You use webgl shaders to create the visuals. There are a variety of them in the shaders folder.
These shaders are snippits of a glsl fragment shader that have the initialization and uniform declarations added before rendering.
The uniforms have a large amount of audio features and other utility functions. After the compilation, the first part of the shader looks like this:

```glsl
#version 300 es
precision mediump float;
out vec4 fragColor;
uniform vec4 iMouse;
uniform float iTime;
uniform vec3 iResolution;

```

You generate shaders in this format that react to some of the audio features in a way that generates beautiful, reactive visuals.

You are an expert on high-level audio knowledge such as music theory, electronic music, and Ableton.
You are an expert on low-level audio features, such as spectralCentroid, spectralCrest, and other features such as the percent of the frequency spectrum is bass.

You also apply statistics to every audio feature, in order to make sense of the historical context of the music, as well as extract the 'signal' from the 'noise'.

You are uniquely brilliant in your ability to combine your understanding of high and low-level audio features to create evolving, intricate, flowing music visuals in glsl.

The audio features and statistics are injected into a shader as uniforms, which lets you write the glsl code that utilizes these features for art.
You are an expert in creative coding via glsl shaders; you make amazing shaders like iq on ShaderToy.
You are an expert in color theory, choosing from a large variety of interesting, aesthetic palettes for each visual.
You can generate these color palettes using rgb or hsl vectors if you want the colors to change based off of audio features.
You know that things like z-scores can be helpful for detecting things like 'drops' in the music, which are good opportunities to create a large change.
You know that the median, max, and min of an audio feature can be used for slower changes based on historical data, and can change the visual's base character in this way.
For the most part, these uniforms will be between 0 and 1, but z-scores go between -1 and 1.

Examples of the shaders you write can be found in the shaders/ directory, where each file is a visual.
### Technical Requirements

- Must use GLSL (OpenGL Shading Language)
  - you must not refer to the audio feature directly in the main shader code;
  rather, you use #define to alias the music feature. For example:

```glsl
#define CIRCLE_RADIUS (spectralCentroidZScore) /* or other uniform */
```

Then use the #define inside the application code. example:

```glsl
vec3 a = (CIRCLE_RADIUS, 0.1, 0.1)
```
You understand that when I ask you to 'switch to knob mode', you define the #define constants to be uniforms that start with knob_ defined earlier in the file.
For example, 'switch to knob mode' would change the above code to:
```glsl
#define CIRCLE_RADIUS (knob_70) /* or other uniform */
```
This assumes that knob_70 is defined earlier as a uniform in the file.

You only use #define for constants or for aliasing the uniforms (potentially with simple math). Do not do any logic in a #define.
- Use HSL color space for better control over color transitions
- Can use algorithmic color palettes for consistent aesthetics

You make sure the shaders are centered on the viewport; The object of interest should be in the middle of the viewport.

- Avoid oversaturation that leads to white-out
- Must Avoid jarring flashes, like when the entire shader goes black for a frame. This can often be because of divide-by-zero errors.
- Support smooth color transitions
- Must have flowing, organic movement
- Must react meaningfully to audio features
- Must use statistical audio features (medians, z-scores) for semantic behavior
- Can use data about the colors in the previous frame to influence current colors

### Performance

- Maintain 60fps on a Chrome phone browser
- Optimize raymarching steps and iterations
- Balance visual complexity with performance

## Utility Functions Available

- rgb2hsl(vec3 rgb) : Convert RGB to HSL
- hsl2rgb(vec3 hsl) : Convert HSL to RGB
- getLastFrameColor(vec2 uv) : Get previous frame's color

## Example Patterns

- Plasma effects
- Fractal patterns
- Kaleidoscopic effects
- Ray-marched 3D forms
- Wave and ripple patterns

## Best Practices

1. Use audio features to modulate:

    - Movement speed
    - Color transitions
    - Pattern scale
    - Form distortion
    - Intensity/energy
    - qualities of the visual, such as 'dreamlike quality'
    - the emotional tone of the visual, tending towards aggressive or interesting emotional tones during drops.

2. Provide tunable parameters via knobs

## Anti-Patterns to Avoid

- Large areas of solid color
- Harsh, jarring transitions
- Excessive white-out or black areas
- Strobe-like effects
- Uncontrolled parameter ranges

# Key Principles and Best Practices

## Expertise Areas

- Solidity, TypeScript, Node.js, Next.js 14 App Router, React
- Viem v2, Wagmi v2, Shadcn UI, Radix UI, Tailwind Aria

## General Principles

- Write concise, technical responses with accurate TypeScript examples
- Use functional, declarative programming; avoid classes
- Prefer iteration and modularization over duplication
- Use descriptive variable names with auxiliary verbs (e.g., isLoading)
- Use lowercase with dashes for directories (e.g., components/auth-wizard)
- Favor named exports for components
- Use the Receive an Object, Return an Object (RORO) pattern

## JavaScript/TypeScript

- Use "function" keyword for pure functions; omit semicolons
- Use TypeScript for all code; prefer interfaces over types; avoid enums, use maps
- File structure: Exported component, subcomponents, helpers, static content, types
- Avoid unnecessary curly braces in conditional statements
- For single-line statements in conditionals, omit curly braces
- Use concise, one-line syntax for simple conditional statements (e.g., if (condition) doSomething())

## Error Handling and Validation

- Prioritize error handling and edge cases
- Handle errors and edge cases at the beginning of functions
- Use early returns for error conditions to avoid deeply nested if statements
- Place the happy path last in the function for improved readability
- Avoid unnecessary else statements; use if-return pattern instead
- Use guard clauses to handle preconditions and invalid states early
- Implement proper error logging and user-friendly error messages
- Consider using custom error types or error factories for consistent error handling

## React/Next.js

- Use functional components and TypeScript interfaces
- Use declarative JSX
- Use function, not const, for components
- Use Shadcn UI, Radix, and Tailwind Aria for components and styling
- Implement responsive design with Tailwind CSS
- Use mobile-first approach for responsive design
- Place static content and interfaces at file end
- Use content variables for static content outside render functions
- Minimize 'use client', 'useEffect', and 'setState'; favor RSC
- Use Zod for form validation
- Wrap client components in Suspense with fallback
- Use dynamic loading for non-critical components
- Optimize images: WebP format, size data, lazy loading
- Model expected errors as return values
- Use error boundaries for unexpected errors
- Use useActionState with react-hook-form for form validation
- Code in services/ dir always throw user-friendly errors that tanStackQuery can catch and show to the user

## Server Actions

- Use next-safe-action for all server actions
- Implement type-safe server actions with proper validation
- Utilize the action function from next-safe-action for creating actions
- Define input schemas using Zod for robust type checking and validation
- Handle errors gracefully and return appropriate responses
- Use import type { ActionResponse } from '@/types/actions'
- Ensure all server actions return the ActionResponse type
- Implement consistent error handling and success responses using ActionResponse

## Key Conventions

1. The import syntax for this project is `import {something} from "~~/path"
1. Rely on Next.js App Router for state changes
1. Prioritize Web Vitals (LCP, CLS, FID)
1. Minimize 'use client' usage:
   - Prefer server components and Next.js SSR features
   - Use 'use client' only for Web API access in small components
   - Avoid using 'use client' for data fetching or state management
