@encode42/nbs.js NPM

NBS.js

A versatile API for reading, manipulating, and writing OpenNBS files, inspired by NBSEditor and NBS4j.

It's cleanroom, too! No required dependencies!

🔧 Including

!TIP When using jsdelivr links, it's recommended to use versioned links! (e.g. @encode42/nbs.js@3.0.0)
!WARNING
3.0.0 is not the latest version of NBS.js! The above is just an example.

❔ FAQ

Install NBS.js for your platform, then refer to the documentation and examples below.

<input type="file" id="file-input">

<script src="https://cdn.jsdelivr.net/npm/@encode42/nbs.js"></script> <!-- Import NBS.js -->
<script>
window.addEventListener("load", () => {
	const input = document.getElementById("file-input");

	// Initialize file input
	input.addEventListener("change", () => {
		const songFile = input.files[0]; // Read the selected NBS file
		songFile.arrayBuffer().then(buffer => { // Convert it into an ArrayBuffer
			const song = NBSjs.fromArrayBuffer(buffer); // Parse the buffer

			console.dir(song);
		});
	});
});

console.dir(song);

import { fromArrayBuffer } from "https://cdn.jsdelivr.net/npm/@encode42/nbs.js/dist/esm.js";

const songFile = await Deno.readFile("song.nbs"); // Read the selected NBS file

console.dir(song);

Yes! A demo site is located here. It serves as an example of how to read NBS files, allows you to edit the song structure, and plays the result through the browser.

This repository also contains tests that could be used as examples.

I don't create GitHub releases, but I do keep a changelog here!
