@wyreup/core

Privacy-first, browser-native tool library. Tools for images, PDFs, audio, and text — every operation runs on-device using WebAssembly and browser-native APIs. Nothing uploads.

Install

npm install @wyreup/core

Requires Node >= 20. Works in browser, Node, and edge runtimes (dual build).

Usage

import { createDefaultRegistry } from '@wyreup/core';
import { readFile } from 'node:fs/promises';
import { randomUUID } from 'node:crypto';

const registry = createDefaultRegistry();
const tool = registry.toolsById.get('compress');

// Read input file
const bytes = await readFile('photo.jpg');
const input = new File([bytes], 'photo.jpg', { type: 'image/jpeg' });

// Run the tool
const ctx = {
  onProgress: () => {},
  signal: new AbortController().signal,
  cache: new Map(),
  executionId: randomUUID(),
};
const result = await tool.run([input], { quality: 80 }, ctx);
// result is a Blob or Blob[]

Chain tools

import { createDefaultRegistry, runChain, parseChainString } from '@wyreup/core';
import { randomUUID } from 'node:crypto';

const registry = createDefaultRegistry();
const chain = parseChainString('strip-exif|compress[quality=75]');

const ctx = {
  onProgress: () => {},
  signal: new AbortController().signal,
  cache: new Map(),
  executionId: randomUUID(),
};

const outputs = await runChain(chain, [inputFile], ctx, registry);
// outputs is Blob[]

Dual build

@wyreup/core ships two builds:

• dist/browser/index.js — for browser and bundler environments (uses WebAssembly workers)
• dist/node/index.js — for Node and CLI environments

Your bundler resolves the right one automatically via the exports map.
