https://github.com/blakeembrey/change-caseA monorepo of pure ESM utilities for transforming strings between casing formats. Includes the core change-case library for standard transformations (camelCase, snake_case, PascalCase, etc.), sponge-case for random capitalization, swap-case for swapping character cases, and title-case for English title-style formatting. All packages include TypeScript definitions and support custom options for delimiters, locales, and word splitting.
The change-case monorepo provides a suite of tools for transforming strings between various formats such as camelCase, PascalCase, Capital Case, snake_case, param-case, and CONSTANT_CASE.
The monorepo is split into several specialized packages:
change-case: The core package for standard case transformations.sponge-case: Specialized case transformations.swap-case: For swapping character cases.title-case: For title-style formatting.title-case package is a pure ESM package and includes TypeScript definitions. It is not compatible with CommonJS require() or CommonJS module resolution in TypeScript projects.The sponge-case package is a pure ESM package and includes TypeScript definitions.
Important: Because it is pure ESM, you cannot use require() to import it, and it cannot be used with CommonJS module resolution in TypeScript. You must use ESM import syntax.
change-case package is a pure ESM package and includes TypeScript definitions. It cannot be used with require() or with CommonJS module resolution in TypeScript environments.The swap-case package is a pure ESM package and includes TypeScript definitions.
Important: You cannot use require() or CommonJS module resolution with this package in TypeScript. You must use ESM import syntax.
All packages in this monorepo are pure ESM packages and include TypeScript definitions.
Important Constraints:
require() to import these packages.To use the change-case library in your project, install it using npm:
npm install change-case --saveTo use the title-case package in your project, install it using npm:
npm install title-case --saveThe core library provides several methods to transform strings between different casing formats. You can import all methods as a namespace to access them.
Note: change-case is designed for programming cases. It does not retain punctuation or sensitivities. For generic title or sentence casing, use the title-case package instead.
import * as changeCase from "change-case";
changeCase.camelCase("TEST_VALUE"); //=> "testValue"To use the swap-case package in your project, install it using npm:
npm install swap-case --saveTo use sponge-case in your project, install it using npm:
npm install sponge-case --saveAll case transformation methods accept an options object as a second argument to customize behavior:
delimiter?: string: The character to use between words. Default depends on the method (e.g., _ in snakeCase).locale?: string[] | string | false: Specifies the locale for lower/upper casing. Defaults to the host environment. Set to false to disable.split?: (value: string) => string[]: A function to define how the input is split into words. Defaults to the internal split utility.prefixCharacters?: string: Characters to retain at the beginning of the string. Defaults to "".suffixCharacters?: string: Characters to retain at the end of the string. Defaults to "".Ambiguous Characters: By default, pascalCase and snakeCase separate ambiguous characters with _ (e.g., V1.2 becomes V1_2). You can use mergeAmbiguousCharacters: true in the options to merge them instead.
