fetch('./example.nbt')
	.then(res => res.arrayBuffer())
	.then(data => {
		const { value, name, compression } = readNbt(new Uint8Array(data))

		const newData = writeNbt(value, { name, compression })
	})

Rendering a structure

import { Structure, StructureRenderer } from 'deepslate'
import { mat4 } from 'gl-matrix'

const structure = new Structure([4, 3, 4])
structure.addBlock([0, 0, 3], "minecraft:stone")
structure.addBlock([0, 1, 3], "minecraft:cactus", { "age": "1" })

// Obtain the WebGL context of a canvas element
const gl = canvas.getContext('webgl')

// See the example on how to create a resources object
const renderer = new StructureRenderer(gl, structure, resources)

const view = mat4.create()
mat4.translate(view, view, [0, 0, -5])

renderer.drawStructure(view)
