Awesome Cursor Rules Collection

Utilise pnpm pour les dépendances

Oui, il existe plusieurs outils pour visualiser les flux de données dans le code :

1. **VSCode Extensions** :
   - "Code Map" : Crée des diagrammes de flux de données
   - "Dependency Cruiser" : Visualise les dépendances entre fichiers
   - "CodeFlow" : Montre le flux d'exécution du code

2. **Outils de Visualisation** :
   - **Mermaid.js** : Permet de créer des diagrammes de flux directement dans le markdown
   - **PlantUML** : Similaire à Mermaid, plus complet mais plus complexe

3. **Outils d'Analyse Statique** :
   - **Madge** : Génère des graphes de dépendances
   - **TypeScript Dependency Graph** : Spécifique à TypeScript

Par exemple, avec Mermaid.js, on pourrait visualiser le flux de notre videoId comme ça :

```mermaid
graph LR
    A[URL YouTube] --> B[extractVideoId]
    B --> C[cleanVideoId]
    C --> D[DecorationForUrl constructor]
    D --> E[this.videoId]
    E --> F[toVideoId]
    F --> G[playerService.loadVideo]
```

Voulez-vous que je vous montre comment mettre en place un de ces outils pour notre projet ?




PlayerView : La vue Obsidian elle-même
ViewModeService : Gère la création/fermeture des vues et leur mode
PlayerUI : Gère l'interface utilisateur du lecteur
PlayerService : Gère la logique métier du lecteur


Je vois maintenant que le resize est géré différemment de ce que nous pensions :
   Dans PlayerService :
   Il utilise un ResizeObserver pour détecter les changements de taille du container
   Il émet un événement 'view:resize' via eventBus
   Dans utils.ts :
   Il y a des fonctions saveHeight et getHeight qui gèrent la persistance et la récupération des hauteurs
   Ces fonctions sont liées aux settings et au mode de vue
La méthode resize dans IPlayerUI n'est en fait pas nécessaire car :
Le redimensionnement est géré au niveau du service via ResizeObserver
La persistance est gérée via les utils
L'UI n'a pas besoin de gérer directement le resize
Je suggère donc de :
Soit modifier l'interface IPlayerUI pour retirer la méthode resize
2. Soit vérifier où cette interface est utilisée pour comprendre pourquoi elle requiert cette méthode
Voulez-vous que je vérifie l'interface IPlayerUI pour voir où elle est définie et utilisée ?


Avant de passer en production, voici ce qu'il nous reste à faire :
1. Corriger les tests (priorité haute)
Résoudre les problèmes de Type Guards
Corriger les messages d'erreur (internationalisation)
Fixer les tests d'intégration
Vérification de la configuration (priorité haute)
Le manifest.json semble correct mais il faudrait :
Vérifier la compatibilité de la version minimale d'Obsidian
Ajouter des mots-clés pour le référencement
Préciser le type de licence (actuellement trop générique)
Documentation (priorité moyenne)
Mettre à jour le README.md avec :
Instructions d'installation
Guide d'utilisation
Captures d'écran
Section de dépannage
4. Build et Distribution (priorité haute)
Vérifier que le build fonctionne correctement
Tester le plugin dans une installation propre d'Obsidian
Préparer les assets pour la soumission au marketplace d'Obsidian
Voulez-vous que nous commencions par la correction des tests ? C'est l'étape la plus critique avant de pouvoir envisager une release en production.
Pour les Type Guards, je propose de commencer par examiner le code des fonctions de vérification de type dans le fichier des erreurs.


Ne retire jamais les commentaires principaux (ceux qui ne sont pas indentés), ils me servent à me retrouver dans le code.
TU es un expert dans l'API de l'application de prise de notes Obsidian https://docs.obsidian.md ainsi que sont éditeur sous jacent CodeMirror https://codemirror.net/docs/ref/
Tu fais toujours attention au contexte du projet et de la conversation dans tes réponses.
Quand une solution nécessite d'implémenter plusieures choses différentes, tu les gardes en mémoire et propose un plan pour les implémenter une part une tout en m'expliquant ce que je ne comprends pas (je début en Javascript).
Tu utilises les bonnes pratiques de développement web car nous souhaitons créer un plugin pour Obsidian qui sera facile à maintenir ou faire évoluer et qui soit super robuste.

Fais une seule chose à la fois et demande moi d'abord, et vérifie toujours le code existant avant de te lancer dans une création ou une réponse

Gestion des vues :
La classe PlayerContainer est très longue et contient beaucoup de logique
Elle devrait probablement être dans un fichier séparé dans src/views/
Gestion des événements :
Les événements sont gérés directement dans main.ts
Il manque peut-être un service dédié à la gestion des événements


Voici mon plan d'action proposé :
D'abord, créer un nouveau fichier pour PlayerContainer :
Déplacer la classe dans src/views/PlayerContainer.ts
Nettoyer les imports
Ensuite, créer un nouveau service StoreService :
Implémenter le pattern singleton correctement
Migrer les références depuis archive/store
Enfin, créer un service EventService :
Gérer les événements de l'application
Migrer la logique des événements depuis main.ts
Voulez-vous que je commence par l'une de ces tâches en particulier ?



Remplacé les références à Store.get() par les services appropriés
Utilisé this.settings et this.playerViewAndMode directement

You are an expert in TypeScript, Node.js, Next.js App Router, React, Shadcn UI, Radix UI and Tailwind developing TripSync, a web app for collaborative trip planning.

The key aspect of this project is multiplayer collaboration, without using any backend or database, but using ReactTogether for multiplayer collaboration components, sharing useStates. ReactTogether is a library that allows you to share state between multiple users in real-time, that came from Multisynq and Croquet. 


Key Principles
- Write concise, technical TypeScript code with accurate examples.
- Use functional and declarative programming patterns; avoid classes.
- Prefer iteration and modularization over code duplication.
- Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
- Structure files: exported component, subcomponents, helpers, static content, types.
- Use ReactTogether for multiplayer collaboration components.

Naming Conventions
- Use lowercase with dashes for directories (e.g., components/auth-wizard).
- Favor named exports for components.

TypeScript Usage
- Use TypeScript for all code; prefer interfaces over types.
- Use functional components with TypeScript interfaces.

UI and Styling
- Use Shadcn UI, Radix, and Tailwind for components and styling.
- Implement responsive design with Tailwind CSS; use a mobile-first approach.
- Primary color should be #e56f5f (like a salmon/orange color)
- Instead of black for fonts use  #121827 (very dark blue)
- For background use #fffdf9ff instead of white (very very light cream)
- Play with the color opacity to make it look modern and clean.

- Use camelCase for variables and functions
- Use PascalCase for React components

### File Structure

```
components/
  Button/
    button.tsx
    button.module.styl
  Card/
    card.tsx
    card.module.styl
```

### Coding Standards (based on Standard.js)

- Use 2 space indentation
- Use single quotes for strings (except to avoid escaping)
- No semicolons (unless required to disambiguate statements)
- No unused variables
- Add a space after keywords and before function parentheses
- Always use === instead of ==
- Space infix operators and after commas
- Keep else statements on the same line as their curly braces
- Use curly braces for multi-line if statements
- Always handle the err function parameter

### Best Practices

- Lift state up when needed to share state between components
- Use context for intermediate state sharing
- Use 'nuqs' for URL search parameter state management

## UI and Styling

- Use Shadcn UI and Radix UI for component foundations
- Implement responsive design with Tailwind CSS (mobile-first approach)
- Use Stylus as CSS Modules for component-specific styles
- Combine Tailwind utility classes with Stylus modules:
  - Use Tailwind for common utilities and layout
  - Use Stylus modules for complex, component-specific styles
  - Never use the @apply directive
- Implement a consistent naming convention for CSS classes (e.g., BEM) within Stylus modules

### Stylus Best Practices

- Use variables for colors, fonts, and other repeated values
- Create mixins for commonly used style patterns
- Utilize Stylus' parent selector (&) for nesting and pseudo-classes
- Keep specificity low by avoiding deep nesting

## Performance Optimization

- Minimize 'use client', 'useEffect', and 'useState'

I'm building a DuckDB extension for Notion.

Here are some examples of DuckDB Extensions:
- Google Sheets: https://github.com/evidence-dev/duckdb_gsheets
- Azure: https://github.com/duckdb/duckdb_azure
- HTTP(S): https://github.com/duckdb/duckdb/tree/main/extension/httpfs
- Iceberg: https://github.com/duckdb/duckdb_iceberg

In particular, the Google Sheets extension is the most similar to what we're trying to build, so it may be a good reference.
Much of the starter code in this repo is based on the Google Sheets extension.

In addition, for reference, here is the Notion API reference: https://developers.notion.com/reference/intro

For the extension, we may want to use some of the following Notion API endpoints:
- Authenticate: https://developers.notion.com/reference/authentication
- List databases: https://developers.notion.com/reference/post-search
- Get the schema of a database: https://developers.notion.com/reference/retrieve-a-database

# .cursorrules for Python Project: PyObsidian

## General Python Project Guidelines

- **Typing Annotations**: All Python functions and classes must include typing annotations. Be explicit about return types where applicable.
- **Docstrings**: Ensure that all Python functions and classes are documented using docstrings following PEP257 conventions. Update or enhance existing docstrings when necessary.

- **Comments**: Retain any existing comments in files to ensure clarity and maintain context.

- **Tests**:

  - All tests must be written using `pytest` or its plugins.
  - Do not use the `unittest` module.
  - Ensure every test is fully typed and includes docstrings.
  - All tests should be placed under the `./tests` directory. If this directory or relevant subdirectories do not exist, create them.
  - If new test files are added inside `./tests` or `./pyobsidian`, ensure that an `__init__.py` file is present.
  - Import necessary modules such as:

    ```python
    from typing import TYPE_CHECKING
    from pytest.capture import CaptureFixture
    from pytest.fixtures import FixtureRequest
    from pytest.logging import LogCaptureFixture
    ```

- **Directory Structure**: Follow a clean directory structure with separate folders for source code, tests, documentation, and configuration.

  - Use distinct files for models, services, controllers, and utilities.

- **Configuration**:

  - Manage configurations through environment variables. Avoid hardcoded paths or configurations.

- **Error Handling**:

  - Implement robust error handling across the project. Use logging to capture detailed context for debugging.
  - Ensure that errors are logged with appropriate severity levels (e.g., `info`, `warning`, `error`, `critical`).

- **Code Style**:

  - Ensure consistent code style using `Ruff` for linting. Keep code formatting uniform throughout the project.

- **Dependency Management**: Use the PyObsidian repository from `<https://github.com/felipepimentel/pyobsidian>` and virtual environments to manage dependencies. Do not rely on system-wide installations.

## Command Creation Guidelines

When creating a new command, follow these guidelines:

1. **File Creation**:

   - Add your command in a file with the suffix `_command.py` inside the `**/pyobsidian/commands/**` directory.
   - Example: `/pyobsidian/commands/my_custom_command.py`.

2. **Function Definition**:

   - Define your command using `@click.command()` from the `click` library.
   - Use `@click.option()` or `@click.argument()` to define any parameters the command might need.
   - Access the global context `obsidian_context` where necessary.

   - **IMPORTANT**: All **display and output** functions (such as `click.echo`, `display_table`, or any other kind of output handling) must be placed in the **`/pyobsidian/ui_handler.py`** module. **Do not define display logic inside command handlers or core logic**. Ensure that each command performs its core task, delegating output responsibilities to the `ui_handler`.

3. **Example of a Basic Command**:

   Example of a command that follows the project guidelines, delegating display logic to the `ui_handler`:

   ```python
   import click
   from ..core import obsidian_context
   from ..ui_handler import display_notes

   @click.command()
   def list_notes() -> None:
       """List all notes in the Vault."""
       notes = obsidian_context.vault.get_all_notes()
       display_notes(notes, format="table", title="All Notes")

   def register_command(cli: click.Group) -> None:
       """Register the list-notes command to the CLI group."""
       cli.add_command(list_notes, name="list-notes")
   ```

- Limit 'useEffect':
- Use only for Web API access in small components.
- Avoid for data fetching or state management.

**Follow React Native Expo docs for Data Fetching, Rendering, and Routing.**

# Project-Specific Cursor Rules for AI

You are an expert in TypeScript, Next.js 14 (with App Router), Shadcn UI, Tailwind CSS, Magic UI, tRPC, Supabase, and Vercel.

## General Code Structure:
- Always use **kebab-case** for file and folder names (e.g., `api-routes`, `user-profile.tsx`).
- Use **TypeScript** for all files. Ensure full type safety with strict TypeScript rules (e.g., `strictNullChecks`, `noImplicitAny`).
- Leverage **ESLint** with Airbnb or a similar configuration for code quality checks.
- Apply **Prettier** for consistent formatting, ensuring readability and clean code.

## Next.js 14 with App Router:
- **Server Actions**: Use **Server Actions** whenever possible for server-side logic like form submissions and data handling. This will reduce client-side code and improve performance.
  - Example: For form submissions, write `POST` logic in a server action to avoid excessive client-side API calls.
- **File Structure**: Organize components within the `app` directory, following **kebab-case** conventions.
  - Group related components and pages into nested folders under the `app` directory (e.g., `/app/user-profile/page.tsx`).
- Use **dynamic routing** when handling multiple resources with a common structure (e.g., `/app/products/[productId]/page.tsx`).

## tRPC and API Routes:
- Use **tRPC** to handle all API logic via `api-routes`. Prefer **React Query** on the client side for data fetching and caching.
- **Validation**: Apply **Zod** schema validation to all tRPC endpoints for type-safe input validation.
  - Example: In `/app/api/trpc/[trpc]/route.ts`, ensure `Zod` schemas are applied for request validation.
- **Server-Side Caching**: Use **React Query**’s `stale-while-revalidate` for client-side caching and performance optimization when making API requests via tRPC.

## UI and Styling with Shadcn UI, Magic UI, and Tailwind CSS:
- **Shadcn UI**: Use pre-built **Shadcn components** for UI consistency and modularity. Prioritize customizability to fit the branding and design needs of the project.
- **Tailwind CSS**: For layout and styling, use Tailwind CSS. Stick to the utility-first classes.
  - Tailwind Config: Ensure the config includes custom colors and themes that fit the project’s style.
  - Example: Use Tailwind for responsive designs and apply `@media` queries when needed.
- **Magic UI**: For micro-animations and interactive elements, apply **Magic UI** to enhance user experience, but use it sparingly to maintain performance.
  - Example: Add subtle animations on button hover or form submissions using Magic UI components.

## Database and Backend with Supabase:
- Use **Supabase** as the primary database (PostgreSQL). All database queries and logic should be handled in **server actions** or through tRPC API routes.
- Prefer **Supabase Auth** for authentication and role-based access control (RBAC).
- For database interaction, use **Supabase client libraries** with full TypeScript support.
  - Example: When fetching data, prefer the `supabase.from('table')` syntax, ensuring all queries are optimized for performance.

## Vercel Hosting and Deployment:
- All deployments will be handled through **Vercel**.
  - Ensure the project is optimized for **Edge Functions** (serverless).
  - Use **Vercel Analytics** for monitoring performance and user interactions.

## State Management with React Query:
- For global state, prefer **React Query** over Redux or Context API.
- Apply React Query’s `invalidateQueries` pattern after any data mutation (e.g., updates, deletes) to keep client data fresh.

## Performance Optimization:
- **Lazy Loading**: Lazy load non-essential components like modals or third-party widgets using `React.lazy` and **Next.js dynamic imports**.
- **Code Splitting**: Use **Next.js 14’s App Router** to enable automatic code splitting. Break up larger components into smaller, reusable parts to optimize load times.
- Minimize the use of `use client`. Prefer **Server Components** for rendering UI whenever possible for performance.

## Error Handling:
- Use **Error Boundaries** to catch client-side errors gracefully.
- Leverage **tRPC error handling** to provide meaningful error messages for both the client and server. Validate errors using **Zod** schemas, and return type-safe error responses.

## Security:
- Ensure all **Supabase API keys** are stored in environment variables and never hardcoded into the project.
- Use **HTTPS** and enforce **secure headers** for all API requests (via tRPC or server actions).
- Implement **role-based access control (RBAC)** with Supabase for sensitive data.

## Tests:
- Apply **unit tests** for all business logic and **integration tests** for key components.
  - Use **Jest** or **Vitest** for unit testing components and logic.
  - For integration testing with tRPC, ensure you cover API routes and database interactions.

## Logging and Monitoring:
- Use **Vercel Logs** and **Supabase logs** for monitoring server-side operations.
- Implement structured logging using libraries like **Winston** or **Pino** for both server and client-side logs.

<file_structure>
- use-cases hold the the use cases, they should not depend on infrastructure (database, http, etc.)
- most business logic should be in entities, usecase should orchestrate them
- Separate business logic from infrastructure
- Use index.ts for public API

<security>
- Validate all inputs
- Sanitize user data
- Use secure defaults
- Handle sensitive data carefully
- Never store secrets in code, or comments : use environment variables

This is a vanilla html and js project. 

I am using FastAPI for the backend.

I am using Pymongo/Mongodb for the database.

I am using Bootstrap for the frontend framework. Please do not use Bootstrap utility classes. Only use bootstrap for component classes.

The goal of this project: Create an open source toolkit for AI agents.

# MovieLandia24

## Project Context

MovieLandia24 is a Next.js/React application for discovering movies, TV series, actors, and crew, with user accounts, browsing, reviews, social features following, messaging, notifications system, and admin dashboard.

### Architecture

1. **Presentation:** React components (`src/components`), and App Router (`src/app`).
2. **Business Logic:** Data handling (`src/actions`, `src/hooks`, `src/utils`).
3. **Data Access:** Prisma, Zod (`prisma/schema`, `prisma/schemas`).
4. **API:** Serverless functions, API Routes Handlers (`src/app/api`).
5. **External Services:** Resend (`emails`).

### Features

- User Management (Registration, Login, Password Reset, Google OAuth, Profile).
- Content (Browsing, Search, Details, Reviews/Ratings, Bookmarking).
- Social (Following/Unfollowing, Messaging).
- Admin (Panel, CRUD, Data Export).

### Technologies

- Next.js, React, Material UI, Prisma, Zod, NextAuth.js, Resend, React Hook Form, React Toastify, Framer Motion, Zustand, `nuqs`.

## General Behaviour Instructions Guidelines

- Follow requirements
- Reduce complexity
- Write full code
- Think step-by-step
- Prefer iteration
- Focus on readable code
- Implement fully
- Avoid implementing nonsensical stuff
- Remove TODOs or random comments implement all the code needed
- Ensure completeness
- Include imports
- Be concise
- Return complete solutions
- Prioritize modularity
- If you are uncertain about any aspect of the request or the correct implementation, explicitly state your uncertainty rather than making assumptions.

## Coding Implementation Instructions Guidelines

- Write correct, DRY, functional code.
- Use descriptive names, concise syntax, declarative JSX, avoid classes, use auxiliary verbs.
- Implement accessibility, ensure error handling. Use const, arrow functions.
- Use early returns. Design for reusability. Avoid hardcoding.
- Use `nuqs` for URL state.

### Framework Practices

- For optimal Next.js data flow
- Minimize 'use client'
- Maintain organized files
- Always use Server Actions for data mutation
- Leverage Route Handlers for data fetching in Client Components
- And utilize Server Actions for data fetching within Server Components.

### UI Styling Practices

- Material UI with Emotion & sx props
- Avoid styled-components
- Theme customization
- Responsive design
- Consistent spacing.

### Performance Optimization

- Optimize Web Vitals
- Image optimization
- Code splitting
- Caching
- Minimize bundle size.

### Database Practices

- Prisma for modeling
- validate before CRUD
- Use indexing
- Optimize queries
- Handle errors
- Ensure data integrity.

### Git Usage

#### Commit Message Prefixes:

- **fix:** Bug fix. _Example:_ `fix: user login`
- **feat:** New feature. _Example:_ `feat: user profile update`
- **perf:** Performance improvement.

#### Rules for Git Usage:

- Use lowercase messages. _Example:_ `fix: login issue`
- Keep summary concise (under 50 chars). _Example:_ `feat: update profile`
