@discere-os/libvisio.wasm

WebAssembly port of libvisio - Microsoft Visio document processing library with SIMD optimization and comprehensive TypeScript interface.

About

libvisio is a library and a set of tools for reading and converting MS Visio diagrams.

libvisio requires boost, gperf, icu, librevenge, libxml2 and perl to build. Most up to date code is available from Git repository at libreoffice.org (https://gerrit.libreoffice.org/gitweb?p=libvisio.git) or the mirror at freedesktop.org (http://cgit.freedesktop.org/libreoffice/contrib/libvisio/). See http://wiki.documentfoundation.org/DLP/Libraries/libvisio for more information.

The library is available under MPL 2.0 license.

Features

• Professional C/C++ library compiled to WebAssembly
• Microsoft Visio document format support (VSD, VSDX, VDX)
• SIMD optimizations for enhanced performance
• Complete TypeScript API with type safety
• Browser and Node.js compatibility
• Modern development workflow with Deno

Quick Start

# Install via npm
npm install @discere-os/libvisio.wasm

# Or use with Deno
import Libvisio from "https://deno.land/x/libvisio_wasm/mod.ts"

Usage

import Libvisio from '@discere-os/libvisio.wasm'

const libvisio = new Libvisio()
await libvisio.initialize()

// Process Visio document
const visioData = await fetch('document.vsd').then(r => r.arrayBuffer())
const result = await libvisio.parse(new Uint8Array(visioData))

console.log(`Parsed Visio document: ${result.pageCount} pages`)
