casecraft is a lightweight utility that converts strings between common naming conventions like camelCase, PascalCase, snake_case, kebab-case, and more. It helps developers maintain consistent naming across codebases, APIs, databases, and user-facing content.

Good naming is fundamental to clean code. casecraft ensures your naming follows the right conventions for the right contexts — automatically.

npm install casecraft

Import and use casecraft to convert strings:

import {
  toCamelCase,
  toSnakeCase,
  toKebabCase
} from 'casecraft';

toCamelCase('user_profile_data');
// → userProfileData

// → user_profile_data

toKebabCase('GetUserInfo');
// → get-user-info
