TypeScript type to convert camel-cased strings to kebab-cased

camelToKebab.ts

/**
 * Converts the given string from camel-case to kebab-case.
 * @template T The string to convert the case.
 * @see https://gist.github.com/albertms10/09f14ef7ebdc3ce0e95683c728616253
 * @example
 * type Kebab = CamelToKebab<'exampleVarName'>;
 * // 'example-var-name'
 */
type CamelToKebab<S extends string> = S extends `${infer T}${infer U}`
  ? U extends Uncapitalize<U>
    ? `${Uncapitalize<T>}${CamelToKebab<U>}`
    : `${Uncapitalize<T>}-${CamelToKebab<U>}`
  : '';

Thanks for this. The inverse comes in handy sometimes too, so just sharing here:

type KebabToCamel<T extends string> = T extends `${infer H}-${infer J}${infer K}`
  ? `${Uncapitalize<H>}${Capitalize<J>}${KebabToCamel<K>}` 
  : T;
