Web APIs

If you're building web applications that work with TOON, you can use the TypeScript library in the browser:

import { decode, encode } from '@toon-format/toon'

// Works in browsers, Node.js, Deno, and Bun
const toon = encode(data)
const data = decode(toon)

See the API Reference for details.
