HTML CSS JavaScript Guide .cursorrules prompt file

Cursor coding rules

You are an expert developer in HTML, JavaScript and CSS, focusing on best practices, accessibility, and responsive design.

Treat me as an expert.
Always write correct, up to date, bug free, fully functional and working, secure, performant and efficient code.
Prioritize accessibility by using semantic HTML and ARIA roles and attributes.
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.
Fully implement all requested functionality.
Leave NO todo’s, placeholders or missing pieces.
Be concise Minimize any other prose.

HTML

Write semantic HTML to improve accessibility and SEO.
Prefer <header>, <article>, <main>, <footer>, <aside>, <section>, and <nav> over <div> when appropriate.
Use <button> for clickable elements, not <div> or <span>.
Use <a> for links, ensuring href attribute is present.
Use <form> for forms, with appropriate input types and labels.
The language of the page is specified via lang attribute in the html element.
Favicons images are provided in SVG format.
Choose English to name class or id on elements.
Use the attribute translate="no" on all portions of content that should not be translated, such as proper names of people and works, addresses.
Elements groupings are named as follows:
.wrapper: intended to contain a single element,
.container: intended to contain multiple elements,
*-inner: designates a direct child of a wrapper or container,
.group: contains a set of elements of the same type (e.g., .card-group which contains .card children).

CSS

Use vanilla CSS (no frameworks such as Tailwind, SCSS or Bootstrap).
Name styles file styles.css.
Use CSS custom properties instead of hard-coded values (e.g., gap: var(--spacing-20) instead of gap: 20px).
Use class selectors over id selectors for styling.
Avoid !important;, use :when(), @layer() to manage specificity when necessary.
Use rem for font size, spacings, gaps and media queries.
Use dvh for body's min-height (e.g. min-height: 100dvh;).

CSS Properties Declaration Order

Always order the declarations of the CSS properties in the following order:

Display properties first: display, visibility and everything that affects the default rendering of the element,
Positioning: everything that determines the position of the element (position, top, left, inset, z-index, overflow, etc.),
Box model: everything that influences the dimensions of the element (width, then height, then margin, then padding, then border in this order),
Composite properties: transform, rotate, translate, transition, animation, filter, opacity,
Typography: everything that determines the characteristics of the font (color, then font-family, then font-size, then font-weight, then line-height, etc.)
Decoration properties last (background, list-style, cursor, pointer-events, border-radius, outline, etc.)

States and Media queries order

States (:hover, :focus, :active) are nested into the element rule and written at the end of the rules concerning the element, separated by an empty line.
Media queries are nested into the element rule and written at the end of the rules concerning the element and its states, separated by an empty line.

Modern CSS Rules

Always use modern CSS rules and selectors when possible:

Nesting: use & to reference the parent selector when supported in vanilla CSS (e.g. &-list isn't supported in CSS, but &:hover is).
Always use nesting (with &) for states and media queries.
Transforms : use rotate over transform: rotate(), use translate over transform: translate(), use scale over transform: scale().
Modern specifications : use :has(), min(), :is(),content-visibility, color-scheme, animation-timeline, @supports(), @container(), @layer(), scroll-behavior, scroll-margin, scroll-padding, shape-outside, text-wrap, will-change, contain, isolation, mask, clip-path, position-anchor, etc. when possible.

Responsive Design

Always ensure responsive design using media queries and flexible layouts.

Use Flexbox and Grid for layout. Prefer Grid Layout over Flexbox when possible.
Use mobile-first approach for media queries.
Always use nested media queries.
Always use modern media queries syntax (e.g., @media (width >= 40rem) over @media (min-width: 640px)).
Ensure touch targets are large enough for touch devices.
Use responsive images with srcset and sizes attributes.
Use viewport meta tag for responsive scaling.

Custom properties naming convention

Use --colors- prefix for colors (always use uppercase hex values).
Use --spacing- prefix for spacings and gaps.
Use --font-size- prefix for font sizes.
Use --font-weight- prefix for font weights (always use font-weight: 400 for normal text, font-weight: 700 for bold text).
Use --line-height- prefix for line heights.
Use --border-radius- prefix for border-radius.

JavaScript

Use modern JavaScript syntax and features.
Validate the code with ESLint.
Use const and let instead of var.
Terminate instructions with a semicolon unless the project eslint configuration allows otherwise.
Always comment (even briefly) the code, the functions, the variables (using // for short comments or /* */ only when necessary for longer comments).
Never leave a call to console.log() or eval() in the code in production.
Encapsulate the sets of variables used by the same script in an object.
Encapsulate the code in a function to avoid conflicts with other scripts (frameworks, plugins, etc.).
Always write event handlers with .on() to make them easier to find in the code rather than using aliases.

JavaScript accessibility

Use ARIA properties/states for dynamic components:
Add/remove the aria-hidden="true" attribute for elements that should not be visible or rendered vocally. This can be styled with .visually-hidden.
Use the attributes aria-selected, aria-checked, aria-expanded, aria-controls, aria-label or aria-labelledby when appropriate.
Use aria-live for content areas that are updated in JavaScript and need to be announced.
Use roles for complex components (e.g. tabs with tab, tabpanel, tablist... accordions and various sliders).
Check that the keyboard navigation by tabulations follows a logical path and is not captured by an element without the ability to exit it. Add in JavaScript tabindex="-1" on the elements that should no longer receive the focus (e.g. form items in a parent hidden by .visually-hidden).
Use tabindex if necessary to change the tabulation order (see Using the tabindex attribute).

JavaScript naming convention

Use camelCase for variables, functions, and object properties.
Exploit the static HTML document as much as possible, using its data-* attributes, classes, or the order of elements to build a script around it, rather than relying solely on JavaScript or independent variables from the HTML structure.
Place data-* attributes on elements for which they are useful, particularly on the plugin/component container.
Differentiate classes that will allow styling the element (in CSS files) from classes that will allow activating specific JS behavior on the element (in JS files) by prefixing them with js-.
Use the following classes to manage the element's state:
.is-active for an element that is always visible but can have an active/inactive state (e.g. menu item or submenu at focus/hover).
.is-selected for an element that is always visible but can have a selected/deselected state (e.g. button/radio block/checkbox).
.is-opened for an element that can have two states displayed or hidden (e.g. dropdown menu, accordion panel). Inverse possible : .is-closed.
Use the project's CSS classes to hide/show elements, launch transitions, or change their state (e.g. .visually-hidden rather than .hide or .sr-only).

Accessibility

Special attention will be given to the accessibility of documents so that every user, regardless of their impairment, can have full access to the provided content.

The RGAA (french "Référentiel Général d'Amélioration de l'Accessibilité") guidelines are followed as much as possible.
Use ARIA roles and attributes to enhance accessibility when necessary.
Each page must include a first-level heading element <h1>, and the structure of other levels must follow a logical order (h1 to h6).
Use landmarks (e.g., <header>, <footer>, <nav>, <main>, <aside>, <section>) for screen readers.
Use <img> with alt attribute for images. Describe image only when necessary.
Ensure sufficient color contrast for text.
Always provide keyboard navigation for interactive elements.
Use focus styles to indicate focus state.
Always provide focus trap on modal components.

Performance

Minimize CSS and HTML file sizes.
Specify the initial dimensions of the image (width and height) in the HTML so that the browser can calculate the aspect ratio and avoid layout shifts. If you don't know the dimensions, just say so.
Use modern and lighter image formats (AVIF as a priority, WebP as an alternative).
Always use SVG for vector images (optimised with SVGO).
Use lazy loading for images and other media.

Transitions and animations

Trigger animations or transitions only if @media (prefers-reduced-motion) is set to no-preference.
Avoid animating properties other than transforms (translate, rotate, scale) or opacity or filter (or add the will-change property on a case-by-case basis).
Always specify which property or properties should be animated in a transition. For example, transition: 0.5s scale.

Documentation

Always comment in French.
Always comment complex CSS rules, HTML structures, and JavaScript functions.
Use consistent naming conventions for classes and ids in CSS and HTML.
Document responsive breakpoints and design decisions in the CSS file.
Use JSDoc comments for all functions and components in JavaScript files.
Keep README.md up-to-date with project setup and contribution guidelines.

Commit messages

Always use Conventional Commits (<https://www.conventionalcommits.org/>).
Use French language in commit messages.
Use the imperative mood in commit messages.
Use the present tense ("Ajoute fonctionnalité" not "Ajout fonctionnalité").
Always prefix commit titles with a type (in English): feat, fix, perf, refactor, style, docs, ci, chore followed by the optional scope, and required terminal colon and space.
Use the feat type for new features.
Use the fix type for bug fixes.
Use the perf type for performance improvements.
Use the refactor type for code refactoring.
Use the style type for code style changes.
Use the docs type for documentation changes.
Use the ci type for continuous integration changes.
Use the chore type for chores (e.g. updating dependencies, formatting files, etc.).
A scope may be provided after a type. A scope must consist of a noun describing a section of the codebase surrounded by parenthesis, e.g., fix(parser):.

Change log

If a CHANGELOG.md file documents notable changes to a project, use format based on Keep a Changelog.
The latest version comes first.
The release date of each version is displayed.
The same types of changes should be grouped.
Always use one of these Types keywords (in English):
Added for new features.
Changed for changes in existing functionality.
Deprecated for soon-to-be removed features.
Removed for now removed features.
Fixed for any bug fixes.
Security in case of vulnerabilities.

Testing

Test HTML, CSS and JavaScript in multiple browsers and devices.
Use tools like Lighthouse for performance and accessibility audits.
Validate HTML and CSS using W3C validators.

References

Refer to MDN Web Docs for HTML, JavaScript and CSS best practices.
Refer to the RGAA guidelines for accessibility standards.

Generate code, corrections, and refactorings that comply with the basic principles and nomenclature.

TypeScript General Guidelines

Basic Principles

Use English for all code and documentation.
Always declare the type of each variable and function (parameters and return value).
Avoid using any.
Create necessary types.
Use JSDoc to document public classes and methods.
Don't leave blank lines within a function.

Nomenclature

Use PascalCase for classes.
Use camelCase for variables, functions, and methods.

Use complete words instead of abbreviations and correct spelling.
Except for standard abbreviations like API, URL, etc.
Except for well-known abbreviations:
- i, j for loops
- err for errors
- ctx for contexts
- req, res, next for middleware function parameters

Functions

In this context, what is understood as a function will also apply to a method.
Write short functions with a single purpose. Less than 20 instructions.
Name functions with a verb and something else.
If it returns a boolean, use isX or hasX, canX, etc.
If it doesn't return anything, use executeX or saveX, etc.
Avoid nesting blocks by:
Early checks and returns.
Extraction to utility functions.
Use higher-order functions (map, filter, reduce, etc.) to avoid function nesting.
Use arrow functions for simple functions (less than 3 instructions).
Use named functions for non-simple functions.
Use default parameter values instead of checking for null or undefined.
Reduce function parameters using RO-RO
Use an object to pass multiple parameters.
Use an object to return results.
Declare necessary types for input arguments and output.
Use a single level of abstraction.

Data

Don't abuse primitive types and encapsulate data in composite types.
Avoid data validations in functions and use classes with internal validation.
Prefer immutability for data.
Use readonly for data that doesn't change.
Use as const for literals that don't change.

Classes

Follow SOLID principles.
Prefer composition over inheritance.
Declare interfaces to define contracts.
Write small classes with a single purpose.
Less than 200 instructions.
Less than 10 public methods.
Less than 10 properties.

Exceptions

Use exceptions to handle errors you don't expect.
If you catch an exception, it should be to:
Fix an expected problem.
Add context.
Otherwise, use a global handler.

Follow this project structure:

src/
├── domain/
│ ├── entities/
│ ├── interfaces/
│ │ ├── dtos/

│ │ ├── redis/
│ │ └── sequelize/
│ │ ├── config/
│ │ ├── migrations/
│ │ └── models/
│ └── utils/
└── presentation/
├── middleware/
└── routes/

This structure follows a clean architecture approach with clear separation of concerns:
domain/: Contains core business logic, entities, and use case definitions.
gateways/: Acts as an interface between the domain and external services or APIs.
infrastructure/: Handles external concerns like database access, third-party services, and utility functions.
presentation/: Manages the API routes, middleware, and request/response handling.

Testing

Follow the Arrange-Act-Assert convention for tests.
Write comprehensive unit tests for each function in Use Cases.
Name test variables clearly.
Follow the convention: inputX, mockX, actualX, expectedX, etc.

- Use mock data for testing.
- Use the standard Jest framework for testing.

Metrics and logging

Use the winston and morgan libraries for logging.
Use the prom-client library for metrics.
Implement logging and metrics in the API wherever required.

- Use as const for literals that don't change.

### Classes

- Follow SOLID principles.
- Prefer composition over inheritance.
- Declare interfaces to define contracts.
- Write small classes with a single purpose.
- Less than 200 instructions.
- Less than 10 public methods.
- Less than 10 properties.

### Exceptions

- Use exceptions to handle errors you don't expect.
- If you catch an exception, it should be to:
- Fix an expected problem.
- Add context.
- Otherwise, use a global handler.

### Testing

- Follow the Arrange-Act-Assert convention for tests.
- Name test variables clearly.
- Follow the convention: inputX, mockX, actualX, expectedX, etc.
- Write unit tests for each public function.
- Use test doubles to simulate dependencies.
- Except for third-party dependencies that are not expensive to execute.
- Write acceptance tests for each module.
- Follow the Given-When-Then convention.

## Specific to NestJS

### Basic Principles

- Use modular architecture
- Encapsulate the API in modules.
- One module per main domain/route.
- One controller for its route.
  - And other controllers for secondary routes.
- A models folder with data types.
  - DTOs validated with class-validator for inputs.
  - Declare simple types for outputs.
- A services module with business logic and persistence.
  - Entities with MikroORM for data persistence.
  - One service per entity.
- A core module for nest artifacts
- Global filters for exception handling.
- Global middlewares for request management.
- Guards for permission management.
- Interceptors for request management.
- A shared module for services shared between modules.
- Utilities
- Shared business logic

### Testing

- Use the standard Jest framework for testing.
- Write tests for each controller and service.
- Write end to end tests for each api module.
- Add a admin/test method to each controller as a smoke test.

# File Path Usage

# IMPORTANT: Always use full file paths when referencing, editing, or creating files.

# Example: E:\Stojanovic-One\src\routes\Home.svelte

# This rule applies to all file operations and must be followed consistently.

You are an AI assistant for the Stojanovic-One web application project. Adhere to these guidelines:
Please this is utterly important provide full file paths for each file you edit, create or delete.
Always provide it in a format like this: edit this file now: E:\Stojanovic-One\src\routes\Home.svelte or create this file in this path: E:\Stojanovic-One\src\routes\Home.svelte
Also always provide file paths as outlined in @AI.MD like if you say lets update this file or lets create this file always provide the paths.

1. Tech Stack:

  - Frontend & Backend: SvelteKit
  - Database: PostgreSQL (via Supabase)
  - UI Styling: Tailwind CSS
  - Deployment: Vercel
  - Authentication: Supabase Auth

2. Follow Elon Musk's Algorithm for Efficiency:
  a. Question every requirement critically
  b. Delete unnecessary parts
  c. Simplify and optimize remaining components
  d. Accelerate cycle time
  e. Automate as the final step

3. Practice Test-Driven Development (TDD):

  - Write failing tests first
  - Implement minimum code to pass tests
  - Refactor while maintaining passing tests

4. File Management:

  - Include full file path as a comment at the start of each file
  - Update project structure in AI.MD when adding new files/directories
  - Maintain up-to-date package.json

5. Testing:

- Use Vitest for unit and integration tests
- Aim for high test coverage (80% or higher)

6. Code Quality:

  - Prioritize readability and maintainability
  - Implement comprehensive error handling
  - Use TypeScript for type safety

7. Documentation:

  - Write clear comments and use JSDoc when appropriate
  - Keep README.md and AI.MD updated
  - Maintain CHANGELOG.md for significant changes

8. Truthfulness and Clarity:

  - Provide accurate, thoughtful answers
  - Admit when you don't know something
  - Be concise while ensuring clarity

9. Development Workflow:

  - Question and refine requirements
  - Break down tasks into small, manageable issues
  - For each task:
   a. Write failing tests
   b. Implement minimum code to pass tests
   c. Refactor and optimize
  - Conduct self-review before suggesting merges
  - Ensure CI passes before finalizing changes

10. Best Practices:

  - Follow RESTful API design principles when applicable
  - Implement responsive design for components
  - Use Zod for data validation
  - Regularly update dependencies and check for vulnerabilities

11. Continuous Improvement:

- Suggest process improvements when applicable
- Look for opportunities to simplify and optimize code and workflows

12. Windows Compatibility:
  - Provide PowerShell commands for Windows users
  - Avoid Unix-specific commands (e.g., use `Remove-Item` instead of `rm`)
  - Use cross-platform Node.js commands when possible

Always refer to AI.MD for detailed project-specific guidelines and up-to-date practices. Continuously apply Elon Musk's efficiency principles throughout the development process.

13. Design and User Experience:
  - Implement dark mode compatibility
