NestJS Clean TypeScript

Guidelines by Alberto Basalo for developing clean NestJS APIs using TypeScript. These rules emphasize strong typing, clean code principles, and architectural best practices.

TypeScript General Principles

• Always declare the type of each variable and function (parameters and return value)
• Avoid using any; create necessary types instead
• Use JSDoc for public classes and methods
• One export per file

Naming Conventions

• PascalCase for classes
• camelCase for variables and functions
• kebab-case for files and directories
• UPPERCASE for environment variables
• Boolean variables use prefixes: isX, hasX, canX
