🔤 case-convert

Tiny, dependency-free TypeScript library + CLI for converting text between casing styles. Ships as both ESM and CommonJS — import it or require it, your call.

✨ Features


🪶 Zero dependencies	No runtime deps — just plain, readable TypeScript
🔁 Dual module support	Native ESM (`import`) and CommonJS (`require`) builds
🧰 Library + CLI	Use it in code, or from the terminal
🧵 Four case styles	camelCase, PascalCase, snake_case, kebab-case
📦 Fully typed	`.d.ts` types included, no `@types/*` package needed
✅ CI-checked	Every push is linted and built automatically

📥 Installation

Not published to a registry yet — install straight from this repo:

git clone https://git.infinitewebworks.com/free-tools/case-convert.git
cd case-convert
npm install
npm run build

# use the CLI locally
node dist/cjs/cli.js camel "hello world"

# or link it so `case-convert` resolves as a global command
npm link

🖥️ CLI usage

npx case-convert <camel|pascal|snake|kebab> <text...>

$ npx case-convert camel "hello world example"
helloWorldExample

$ npx case-convert pascal "hello world example"
HelloWorldExample

$ npx case-convert snake "helloWorldExample"
hello_world_example

$ npx case-convert kebab "HelloWorld_Example"
hello-world-example

📦 Library usage

Import only what you need — every converter is a named export.

ESM

import { toCamelCase, toSnakeCase } from "case-convert";

toCamelCase("hello world");   // "helloWorld"
toSnakeCase("HelloWorld");    // "hello_world"

CommonJS

const { toKebabCase, toPascalCase } = require("case-convert");

toKebabCase("HelloWorld_Example");  // "hello-world-example"
toPascalCase("hello-world");        // "HelloWorld"

Dynamic lookup by name

Handy when the target case is only known at runtime (e.g. a CLI flag or config value):

import { converters, CaseName } from "case-convert";

function convert(style: CaseName, text: string): string {
  return converters[style](text);
}

convert("snake", "helloWorld"); // "hello_world"

📚 API reference

Export	Signature	Description
`toCamelCase`	`(input: string) => string`	Converts to `camelCase`
`toPascalCase`	`(input: string) => string`	Converts to `PascalCase`
`toSnakeCase`	`(input: string) => string`	Converts to `snake_case`
`toKebabCase`	`(input: string) => string`	Converts to `kebab-case`
`converters`	`Record<CaseName, (input: string) => string>`	Lookup map of all four converters, keyed by name
`CaseName`	`"camel" \| "pascal" \| "snake" \| "kebab"`	Type of the valid case-name keys

All converters accept mixed input — spaces, snake_case, kebab-case, or camelCase — and normalize before re-casing, so you can convert from any style to any style.
