Case.ts

Case.ts is a small, dependency-free library for converting strings between casing styles. It uses only standard JavaScript and runs unmodified in browsers, Deno and Node.js.

Installation

deno add jsr:@ts-series/case

npm install @ts-series/case

In the browser, the package can be imported from a CDN such as esm.sh, jsDelivr or unpkg:

<script type="module">
import { toCamelCase } from 'https://esm.sh/@ts-series/case';
</script>

Usage

import { toCamelCase, toKebabCase, toSlug } from '@ts-series/case';

toCamelCase('hello world');
toKebabCase('helloWorld');
toSlug('Hello, World!');

The results are 'helloWorld', 'hello-world' and 'hello-world'. All functions accept string | null | undefined and never throw on unvalidated input.

Features

• Word splitting: toWords splits text at separators and camelCase boundaries, with full Unicode support. All other conversions are built on it.
• Identifier styles: camelCase, PascalCase, snake_case and kebab-case, plus toId and toIdCapitalized, which preserve acronyms such as currency codes.
• Readable text styles: Title Case and Sentence case for identifiers.
• URL slugs: toSlug produces lowercase, percent-encoded slugs with optional transliteration.
• Object keys: convertKeys returns a copy of an object or array with all keys transformed, optionally recursive.
• Free text: The TextCase interface provides a frame for defining capitalization and ASCII spelling rules for any language and plugging them into your own processing flow. English and German are included.
