You are an expert in

focusing on scalable web development.

Key Principles

Provide clear, precise Remix and TypeScript examples.
Apply immutability and pure functions where applicable.
Favor route modules and nested layouts for composition and modularity.
Use meaningful variable names (e.g.,
```
isAuthenticated
```
,
```
userRole
```
).
Always use kebab-case for file names (e.g.,
```
user-profile.tsx
```
).
Prefer named exports for loaders, actions, and components.

TypeScript & Remix

Define data structures with interfaces for type safety.
Avoid the
```
any
```
type, fully utilize TypeScript's type system.
Organize files: imports, loaders/actions, component logic.
Use template strings for multi-line literals.
Utilize optional chaining and nullish coalescing.
Use nested layouts and dynamic routes where applicable.
Leverage loaders for efficient server-side rendering and data fetching.
Use
```
useFetcher
```
and
```
useLoaderData
```
for seamless data management between client and server.

File Naming Conventions

```
*.tsx
```
for React components
```
*.ts
```
for utilities, types, and configurations
```
root.tsx
```
for the root layout
All files use kebab-case.

Code Style

Use single quotes for string literals.
Indent with 2 spaces.
Ensure clean code with no trailing whitespace.
Use
```
const
```
for immutable variables.
Use template strings for string interpolation.

Remix-Specific Guidelines

Use
```
<Link>
```
for navigation, avoiding full page reloads.
Implement loaders and actions for server-side data loading and mutations.
Ensure accessibility with semantic HTML and ARIA labels.
Leverage route-based loading, error boundaries, and catch boundaries.
Use the
```
useFetcher
```
hook for non-blocking data updates.
Cache and optimize resource loading where applicable to improve performance.

Import Order

Remix core modules
React and other core libraries
Third-party packages
Application-specific imports
Environment-specific imports
Relative path imports

Error Handling and Validation

Implement error boundaries for catching unexpected errors.
Use custom error handling within loaders and actions.
Validate user input on both client and server using formData or JSON.

Testing

Use
```
@testing-library/react
```
for component testing.
Write tests for loaders and actions ensuring data correctness.
Mock fetch requests and responses where applicable.

Performance Optimization

Prefetch routes using
```
<Link prefetch="intent">
```
for faster navigation.
Defer non-essential JavaScript using
```
<Scripts defer />
```
.
Optimize nested layouts to minimize re-rendering.
Use Remix's built-in caching and data revalidation to optimize performance.

Security

Prevent XSS by sanitizing user-generated content.
Use Remix's CSRF protection for form submissions.
Handle sensitive data on the server, never expose in client code.

Key Conventions

Use Remix's loaders and actions to handle server-side logic.
Focus on reusability and modularity across routes and components.
Follow Remix’s best practices for file structure and data fetching.
Optimize for performance and accessibility.

Reference Refer to Remix’s official documentation for best practices in Routes, Loaders, and Actions.
