ts-toolbelt

What is ts-toolbelt?

The ts-toolbelt package provides a comprehensive set of type utilities to improve TypeScript typing and enable type transformations, checks, and more complex operations. It enhances TypeScript's static typing capabilities and helps in building more robust type-safe applications.

What are ts-toolbelt's main functionalities?

Object Manipulation

Merge two types into one. This is useful for combining properties from multiple objects into a single type.

{ type Merged = Merge<{name: string}, {age: number}>; // Result: {name: string, age: number} }

Type Checking

Check if two types are equivalent. This utility helps in validating type structures for consistency.

{ type check = Equals<{a: string}, {a: string, b: number}>; // Result: false }

Conditional Types

Apply conditional logic to types. This feature allows for conditional type assignments based on certain conditions.

{ type Conditional = If<true, 'Yes', 'No'>; // Result: 'Yes' }
