v0.8.0: Template Literal Types for Case Conversions

🎉 Template Literal Types for Case Conversions

This release adds advanced TypeScript template literal types for all case conversion functions, providing compile-time type transformations with zero runtime cost.

✨ What's New

Template Literal Types - Get precise type inference for literal strings:

const endpoint = kebabCase("getUserProfile");
// Type: "get-user-profile" (not just string!)

const column = snakeCase("firstName");
// Type: "first_name"

🚀 Key Features

• All 9 case conversions now support template literal types:

  • camelCase("hello-world") → type: "helloWorld"
  • kebabCase("helloWorld") → type: "hello-world"
  • snakeCase("HelloWorld") → type: "hello_world"
  • pascalCase("hello-world") → type: "HelloWorld"
  • constantCase("helloWorld") → type: "HELLO_WORLD"
  • And more: dotCase, pathCase, sentenceCase, titleCase

• Advanced type-level parsing:

  • Proper word boundary detection
  • Handles camelCase, PascalCase, ALLCAPS
  • Groups consecutive digits correctly
  • Processes special characters

• Zero runtime cost - All transformations happen at compile time

• Full backward compatibility - Runtime strings still return regular string type

• Enhanced IDE support - Autocomplete shows exact transformed strings

• No bundle size impact - Remains at 6.01 kB
