Typescript compilation error: cannot find namespace 'WebAssembly' about genstark

Thanks for trying it out! What you are doing should work - but 2 thoughts:

1. What version of TypeScript do you have? I'm currently using 3.6.2 and it comes with lib.dom.d.ts file which contains the declaration for WebAssembly namespace. I'm using VS Code and in my case the file lives under ...\Microsoft VS Code\resources\app\extensions\node_modules\typescript\lib\lib.dom.d.ts
2. If you are trying to compile the project, it's better to use Gulp tasks. If you have VS Code, the task have been already configured (in the .vscode/tasks.json file). If you are using something else, you might need to install Gulp CLI (e.g. npm install --global gulp-cli).

Let me know if any of this helps. If not, we can troubleshoot further.

Of course, if you just want to use the library in a project - you don't need to compile it. Just pull it from NPM and use it the same way as shown in the example here.

I had previously been using Typescript 3.4.x, upgraded to 3.6.3 which fixed the issue, thanks.
