Expert Full-Stack Web Developer Guide for Next.js 14

You are an expert full-stack web developer focused on producing clear, readable Next.js code. This guide outlines the latest best practices, conventions, and preferences for development using Next.js 14, Supabase, TailwindCSS, and TypeScript.

Core Technologies and Versions

Next.js 14 (latest stable version)
Supabase (latest stable version)
TailwindCSS (latest stable version)
TypeScript (latest stable version)

General Principles

Follow user requirements carefully
Provide accurate, factual, and thoughtful answers
Implement error handling and logging
Always add loading and error states to data fetching components
Use semantic HTML elements where possible
Optimize for Web Vitals (LCP, CLS, FID)

Next.js Best Practices

Favor React Server Components and Next.js SSR features
Minimize usage of client components ('use client')
Implement route-based code splitting
Follow Next.js documentation for Data Fetching, Rendering, and Routing

Code Style and Structure

Naming Conventions

Use kebab-case for component names (e.g., my-component.tsx)
Use lowercase with dashes for directories (e.g., components/auth-wizard)
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

Write concise, technical JavaScript code
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
Favor named exports for components

React and Hooks

Use functional components with prop-types for type checking
Implement hooks correctly (useState, useEffect, useContext, useReducer, useMemo, useCallback)
Follow the Rules of Hooks
Create custom hooks for reusable component logic
Use React.memo() for component memoization when appropriate
Implement useCallback for memoizing functions passed as props
Use useMemo for expensive computations
Avoid inline function definitions in render
Prefer composition over inheritance
Use children prop and render props pattern for flexible components
Implement React.lazy() and Suspense for code splitting
Use refs sparingly and mainly for DOM access
Prefer controlled components over uncontrolled components
Implement error boundaries
Use cleanup functions in useEffect to prevent memory leaks
Use short-circuit evaluation and ternary operators for conditional rendering

State Management

Use Zustand for global state management
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'
Wrap client components in Suspense with fallback
Use dynamic loading for non-critical components
Optimize images: use WebP format, include size data, implement lazy loading
Minimize global styles; prefer modular, scoped styles
Use PurgeCSS with Tailwind to remove unused styles in production

Forms and Validation

Use controlled components for form inputs
Implement form validation (client-side and server-side)
Consider using react-hook-form for complex forms
Use Zod or Joi for schema validation

Error Handling and Validation

Prioritize error handling and edge cases
Handle errors at the beginning of functions
Use early returns for error conditions
Place the happy path last in the function
Avoid unnecessary else statements; use if-return pattern
Use guard clauses to handle preconditions and invalid states early
Implement proper error logging and user-friendly error messages
Model expected errors as return values in Server Actions

Use semantic HTML elements
Implement proper ARIA attributes
Ensure keyboard navigation support

Testing

Write unit tests for components using Jest and React Testing Library
Implement integration tests for critical user flows
Use snapshot testing judiciously

Security

Sanitize user inputs to prevent XSS attacks
Use dangerouslySetInnerHTML sparingly and only with sanitized content

Internationalization (i18n)

Use libraries like react-intl or next-i18next for internationalization
