@lacspace/case

Convert strings between cases — camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, Title Case & more.

The string-case toolkit — correct on the tricky inputs (acronyms like XMLHttpRequest, numbers like v2, mixed separators). One tiny, typed, dependency-free package instead of a grab-bag of one-function modules.

Install

npm install @lacspace/case      # or pnpm add / yarn add / bun add

Use

import { camelCase, snakeCase, kebabCase, constantCase, titleCase, changeCase } from "@lacspace/case";

camelCase("foo_bar-baz");        // "fooBarBaz"
snakeCase("fooBarBaz");          // "foo_bar_baz"
kebabCase("XMLHttpRequest");     // "xml-http-request"
constantCase("fooBar");          // "FOO_BAR"
titleCase("hello_world");        // "Hello World"

changeCase("fooBar", "kebab");   // "foo-bar"   ← pick the case at runtime

API

| Function | Example | | --- | --- | | camelCase | fooBar | | pascalCase | FooBar | | snakeCase | foo_bar | | kebabCase | foo-bar | | constantCase | FOO_BAR | | dotCase / pathCase | foo.bar / foo/bar | | titleCase / sentenceCase | Foo Bar / Foo bar | | capitalize | Foo | | words(str) | ["foo","bar"] — the splitter behind them all | | changeCase(str, name) | runtime case by name |

words() splits on spaces, _ - . /, camelCase boundaries, acronym boundaries and letter/number boundaries — so every conversion is consistent.
