It's entirely written in TypeScript

[tripulse]

It doesn't seems that any of the code is written in JavaScript.
I think without a TypeScript compiler you could not use the code!

Update your repository information ASAP!

The published version to NPM is build with Typescript and contains the js files, as you can see here: https://unpkg.com/id3-parser

There's no need to add them to the repo.

Edit: You can look here as well https://cdn.jsdelivr.net/npm/id3-parser

Well now with the advent of Deno, this is a non-issue.
