threepipe/lib/assetmanager/import/ZipLoader.js

A 3D viewer framework built on top of three.js in TypeScript with a focus on quality rendering, modularity and extensibility.

import { FileLoader } from 'three';
import { unzipSync } from 'three/examples/jsm/libs/fflate.module.js';
export class ZipLoader extends FileLoader {
    load(url, onLoad, onProgress, onError) {
        this.setResponseType('arraybuffer');
        return super.load(url, (buffer) => {
            // const files = blob.arrayBuffer().then(buff => )
            const files = unzipSync(new Uint8Array(buffer));
            const map = new Map(Object.entries(files).map(([path, fileBuffer]) => {
                return [path, new File([fileBuffer], path)];
            }));
            onLoad?.(map);
        }, onProgress, onError);
    }
