SCON — Schema-Compact Object Notation: WASM module

Rust tape decoder compiled to WebAssembly for browser and Node.js. Used automatically by scon-notation when available.

With scon-notation (recommended)

npm install scon-notation

scon-notation includes scon-wasm as optional dependency — WASM loads automatically.

Standalone in browser (no npm, no build)

<script type="module">
import init, {
  scon_encode,
  scon_to_json,
  scon_minify,
  scon_expand
} from 'https://cdn.jsdelivr.net/npm/scon-wasm@1/scon_wasm.js';

await init();

// Encode JS object to SCON string
const scon = scon_encode({ name: 'test', version: 1 });
console.log(scon);

// Decode SCON string to JS object
const obj = JSON.parse(scon_to_json(scon));
console.log(obj);

// Minify / Expand
const mini = scon_minify(scon);
const expanded = scon_expand(mini, 1);
</script>

Copy, paste, works. No build step, no package manager.

Standalone in Node.js

import init, { scon_encode, scon_to_json } from 'scon-wasm';
await init();

const scon = scon_encode({ users: [{ name: 'Alice' }, { name: 'Bob' }] });
const obj = JSON.parse(scon_to_json(scon));

API

| Function | Description | |----------|-------------| | scon_encode(obj) | JS object to SCON string | | scon_encode_indent(obj, n) | JS object to SCON string with custom indent | | scon_to_json(scon) | SCON string to JSON string (parse with JSON.parse) | | scon_minify(scon) | SCON string to minified single-line | | scon_expand(mini, indent) | Minified SCON to indented format |

Performance

The WASM module uses the Rust single-pass tape decoder — same engine that beats simd-json on 2/3 benchmark datasets.
