@schnsrw/core

WASM-powered document converter for DOCX, ODT, PDF, Markdown, and plain text.

The TypeScript entry point for Casual Core, the document engine behind the Casual Office suite.

npm install @schnsrw/core

Quick start

import { init, convert } from "@schnsrw/core";

await init();

const docx = await fetch("/cv.docx").then((r) => r.arrayBuffer());
const pdf  = await convert(new Uint8Array(docx), { to: "pdf" });

// Save / stream / send — it's just bytes.

API

Five functions. That's the whole surface.

| Function | Purpose | | --- | --- | | init(opts?) | Boot the WASM engine. Call once. | | convert(input, { from?, to }) | One-shot conversion, returns Uint8Array. | | convertToString(input, { from?, to }) | Same, returns a UTF-8 string. Best for md / txt. | | detectFormat(input) | Sniff a buffer's format. | | extractText(input, from?) | Get the plain-text content of a document. |

input may be Uint8Array, ArrayBuffer, or Blob. from is auto-detected if omitted.

Supported formats: docx, odt, pdf, md, txt.
