Pass an ArrayBuffer as input and get results as output

import validate from "@ooxml-tools/validate";

const version = "Microsoft365";
const results = await validate(input, version);
console.log(results);

Where version of one of ["Microsoft365", "Office2007", "Office2010", "Office2013", "Office2016", "Office2019", "Office2021"]

Development

[!NOTE]
If you don't feel like installing all the dependencies you can run the following

./docker.sh

This will start a docker shell with all the dependencies installed. The following commands can then be run in that shell without installing any dependencies (other then docker/docker-compose)

You'll need dotnet 8 installed locally, to whether it's installed run dotnet --version.

You'll also need to install the node_modules via

npm install

Build the library run

npm run build

The built npm package will be output to ./dist/npm/*

ls -l ./dist/npm/

Known issues

It comes with some known issues

• The library is huge, and slow. It's currently base64 encoding the WASM because of the issues getting WASM building across bundlers (help wanted)
• ~~The library base64 encodes the input OOXML file, which is slow. We should be using streaming (help wanted)~~
• The C# is probably very poor quality... I'm not a C# developer (help wanted)
