Introduction

uni-types is a comprehensive TypeScript type utility library that provides 128+ type helpers for safer, cleaner TypeScript development.

Why uni-types?

TypeScript's built-in utility types (Partial, Required, Pick, Omit, etc.) are powerful but limited. uni-types extends them with:

• Deep operations - Transform nested objects recursively
• Tuple manipulation - Head, Tail, Reverse, Flatten, and more
• Type guards - Check types at compile time
• Type inference - Extract types from complex structures
• String transformations - CamelCase, SnakeCase conversions
• Brand types - Nominal typing for type safety
• Numeric operations - Compile-time arithmetic
• Path utilities - Type-safe nested property access

Features

• 🎯 128+ utility types covering common use cases
• 🔒 Fully type-safe with complete TypeScript definitions
• 🚀 Zero runtime overhead - pure type-level utilities
• 📦 Tree-shakable - import only what you need
• 🔄 Deep operations for nested object transformations

Comparison with Built-in Types

Built-in	uni-types	Description
Partial<T>	DeepPartial<T>	Recursively make all properties optional
Required<T>	DeepRequired<T>	Recursively make all properties required
Readonly<T>	DeepReadonly<T>	Recursively make all properties readonly
-	DeepMutable<T>	Remove readonly from all nested properties
Pick<T, K>	PickRequired<T, K>	Make specific properties required
Omit<T, K>	OmitRequired<T, K>	Make properties required except specified
