[124] TiltLoader breaks in a module env #20941

drcmda · 2020-12-24T09:40:00Z

Repro: https://codesandbox.io/s/elegant-villani-9d3hr?file=/src/index.js

import { TiltLoader } from "three/examples/jsm/loaders/TiltLoader"

new TiltLoader().load("/model.tilt", (scene) => console.log(scene))

This is the error message in a local env (Parcel):

TiltLoader.js:42 TypeError: _jszipModuleMin.JSZip is not a constructor
    at TiltLoader.parse (TiltLoader.js:59)
    at Object.onLoad (TiltLoader.js:32)
    at XMLHttpRequest.<anonymous> (three.module.js:36749)

The text was updated successfully, but these errors were encountered:

PS. it looks like the import statement is wrong, TiltLoader imports jszip as:

import { JSZip } from 'three/examples/jsm/libs/jszip.module.min.js'

but the library doesn't seem to have a named export called "JSZip", it's undefined. The default export on the other hand yields a function:

import JSZip from 'three/examples/jsm/libs/jszip.module.min.js'

Btw, I generally wonder why these aren't npm dependencies. jszip is here: https://www.npmjs.com/package/jszip Why would threejs use a local copy? If my app already happens to use jszip, it would now serve it twice, not to mention the headache on your side keeping these dependencies up to date.

Mugen87 · 2020-12-24T10:29:49Z

import JSZip from 'three/examples/jsm/libs/jszip.module.min.js'

If we do this, the example would report:

Uncaught SyntaxError: The requested module '../libs/jszip.module.min.js' does not provide an export named 'default'

So it seems the current import is correct. Could this be a problem of Parcel?

Why would threejs use a local copy?

We do not want to force users into using npm for just working with the example code. Ideally, they can download the repository and host it on a local webserver.

drcmda · 2020-12-24T11:18:56Z

Could this be a problem of Parcel?

I looked, it's a problem with JSzip: Stuk/jszip#349 The lib appears unmaintained and i don't think they will fix it. In that case the loader won't be of much use imo.

Some people have suggested to use https://github.com/101arrowz/fflate instead.

Other projects have moved on as well for the same reason, this PR explains some of the problems with JSZip:

require cycle
missing support for es6 modules
incompatible with Rollup (Parcel, CSB, ...)

We do not want to force users into using npm for just working with the example code. Ideally, they can download the repository and host it on a local webserver.

Not complaining, i was just curious, i just hope at some point in the future this will be re-considered because JSM has incredible value that is held back atm.

drcmda · 2020-12-24T11:34:32Z

Just found this: https://www.npmjs.com/package/@progress/jszip-esm

This is a fork maintained by Telerik where they have fixed it. If you use their package, that's the easiest solution.

Mugen87 · 2020-12-24T12:23:07Z

We could not upgrade JSZip or use forks so far since we rely on an older version of the lib that supports sync unzip. We can only switch to a new library if it also supports this feature.

drcmda · 2020-12-24T13:32:42Z

Understood, wasn't aware they changed the api that drastically. Fflate supports both async and sync, for instance fflate.unzipSync(...). It's smaller (~5kb vs 80kb), faster (they say up to 50%), no module bugs, maintained, seems like a good replacement. For me it's not so pressing, just wanted to try out TiltLoader really, but maybe if time allows it could be amended. =)

mrdoob · 2020-12-26T14:39:28Z

Switching to fflate sounds good to me! 👍

101arrowz · 2020-12-28T01:02:47Z

Hi, author of fflate here! The reason the async version exists in JSZip is beyond me, since it doesn't actually offload the processing to other threads. On the other hand, if the assets in the ZIP are reasonably large (around 500kB), fflate will use worker threads to compress/decompress them faster.

However, I looked at some of the demos using JSZip and they don't seem to load that much data, so using the synchronous unzipping algorithm would be no different to the async version. You could even replace gunzip.js, which is used by the NRRD loader, with fflate because gunzip and unzip use the same core algorithm.

Since it seems the ThreeJS team wants minified ES6 module scripts, I've hand-tuned a minified version of the library and pasted it below. It's 4.4kB (2.2kB gzipped) and supports synchronous ZIP decompression (through the exported unzipSync method) and GZIP decompression (through gunzipSync).

Usage:

import { unzipSync, strFromU8 } from '../libs/fflate.module.min.js';
let arrayBuffer = ... // From XHR, presumably
const zip = unzipSync(new Uint8Array(arrayBuffer));

// If we were using JSZip, the following would be:
// zip.files['data.xml'].asUint8Array()
const dataXmlU8 = zip['data.xml'];
// zip.files['data.xml'].asArrayBuffer()
const dataXmlBuffer = dataXmlU8.buffer;
// zip.files['data.xml'].asText()
const dataXmlText = strFromU8(dataXmlU8);

import { gunzipSync } from '../libs/fflate.module.min.js';
let arrayBuffer = ... // From XHR, presumably

// If we were using gunzip.js, the following would be:
// const gunzip = new Zlib.Gunzip(new Uint8Array(arrayBuffer));
// const data = gunzip.decompress();
const data = gunzipSync(new Uint8Array(arrayBuffer));

Minified code (to put in fflate.module.min.js):

Btw, I generally wonder why these aren't npm dependencies. jszip is here: https://www.npmjs.com/package/jszip Why would threejs use a local copy? If my app already happens to use jszip, it would now serve it twice, not to mention the headache on your side keeping these dependencies up to date.

This duplication issue will still exist if the examples were to use fflate, but since most users seem to think of 4kB as pocket change, it probably doesn't matter.

The library works with TiltLoader but using it with 3MFLoader produces a runtime error:

invalid zip file

This is the place where it happens:

three.js/examples/jsm/loaders/3MFLoader.js

Line 115 in 6a05d60

zip = new JSZip( data ); // eslint-disable-line no-undef

Here is the current example of 3MFLoader: https://threejs.org/examples/webgl_loader_3mf

Mugen87 · 2020-12-28T11:14:48Z

And here is the 3MF example on my dev branch using fflate:

https://raw.githack.com/Mugen87/three.js/dev1/examples/webgl_loader_3mf.html

101arrowz · 2020-12-28T12:15:27Z

The issue there is that in your source code, you pass an ArrayBuffer to fflate.unzipSync but you need to pass a Uint8Array. To fix the problem, use fflate.unzipSync(new Uint8Array(data)). I applied this hotfix within DevTools and the assets were displayed fine after that. Don't worry about performance cost, this is a free operation (just creates an interface to view the same chunk of memory without any copying).

Mugen87 · 2020-12-28T12:27:50Z

Okay, webgl_loader_3mf works now but I get an empty object zip object in webgl_loader_3mf_materials. Please check out:

101arrowz · 2020-12-28T12:33:01Z

That's a bug in either the compressed version or the actual library. Looking into it now. Thanks for the help with debugging.

EDIT: This is actually the result of that file being Zip64. fflate has no plans to support this format because it's designed for files above 4 GB compressed, and JavaScript typed arrays cannot be that big. This can be resolved by unzipping and rezipping the file; when this is done, the unnecessary Zip64 data is removed and a standard ZIP file is produced, which can be read by fflate. @Mugen87 is this a feasible compromise? If not I can probably hack together a Zip64 reader in a few days.

Mugen87 · 2020-12-28T13:06:35Z

@Mugen87 is this a feasible compromise?

I'm afraid no since we can't ask users to unpack and pack 3MF files again. Such things have to work out of the box.

Besides, if JSZip supports Zip64 I expect to have proper supported in other zip libs, too.

Mugen87 · 2020-12-28T13:17:11Z

and JavaScript typed arrays cannot be that big.

Is that really true? I've read this solely depends on the system.

https://stackoverflow.com/a/25741940/5250847

101arrowz · 2020-12-28T19:03:44Z

You have the spec, and you have reality. V8 and Gecko use a 64 bit unsigned integer to store the size of typed arrays, which means a theoretical max of a lot, but they both cap the actual size at 2³¹ on all devices I've tested. Node caps it at 2³². No Zip64 data is strictly necessary while still being possible in JavaScript.

I understand that Zip64 is important, so I'll add support for it. However, this might be a few days of work since it's a much more messy specification.

Mugen87 · 2020-12-28T20:42:33Z

I understand that Zip64 is important, so I'll add support for it.

👍

101arrowz · 2020-12-29T01:47:48Z

Turns out the problem was way easier to fix than I thought. Zip64 support was just added; it works on the 3MF files from what i can tell.

New code (4.6kB, 2.3kB gzipped):

Can you please also share an updated version of fflate.min.js? We need an UMD version for loaders in examples/js.

Besides, when using the above code I get:

fflate.module.min.js:1 Uncaught ReferenceError: exports is not defined

101arrowz · 2020-12-29T09:28:34Z

My bad, updated the code in my most recent comment. I had forgotten to switch the CommonJS exports to ESM. UMD build should already be live on jsDelivr, I believe, but you could probably wrap the minified code to make the UMD build smaller too.

On looking again at the source code here, it seems that a lot of compression libraries could be replaced by a single one, which is probably better to avoid fragmentation...Will create a more complete minified copy soon and create a PR.

EDIT: Here are my (semi) final revisions for the versions:

fflate.min.js (replaces gunzip.js, inflate.js, jszip.js):

Sorry to waste your time with the bugs @Mugen87!

Great! I've completed my first PR to migrate loaders from JSZip.js and gunzip.js to fflate.

I change inflate to fflate in a separate PR when the first one was merged.

Mugen87 · 2020-12-29T12:49:34Z

In FBXLoader, the following code is used from decompression right now:

var inflate = new Inflate( new Uint8Array( reader.getArrayBuffer( compressedLength ) ) ); // eslint-disable-line no-undef
var reader2 = new BinaryReader( inflate.decompress().buffer );

This can be converted to the following when using fflate which seems to work fine:

var data = fflate.unzlibSync( new Uint8Array( reader.getArrayBuffer( compressedLength ) ) ); // eslint-disable-line no-undef
var reader2 = new BinaryReader( data.buffer );

However, VTKLoader and EXRLoader uses Inflate like so:

var inflate = new Inflate( compressed, { resize: true, verify: true } ); // eslint-disable-line no-undef

Notice the additional option parameter. According to the docs resize means:

resize buffer(ArrayBuffer) when end of decompression (default: false)

Both loaders set resize to true. How should this be handled with fflate? Is this even relevant? It seems loading works fine if I use the same approach like FBXLoader.

101arrowz · 2020-12-29T13:18:22Z

I'm not exactly sure what the resize option does, but it seems like an optimization more than anything. I checked its usage in the source code and it seems to change basically nothing; the only difference is allocating a new array of length LEN and copying bytes 0 to LEN into the new array vs. taking the subarray from 0 to LEN directly. If anything, the O(n) allocation + copy would be slower...

I actually took a closer look and found this comment that indicates that it's a memory optimization. This is applied by default in fflate because if it weren't, memory would be about 2x worse.

Mugen87 · 2020-12-29T13:22:06Z

Okay, thanks! As mentioned in my previous post it already works with fflate but I thought it's a good opportunity to clarify the different usages of Inflate.

How could we replace this usage of JSZip with fflate? I guess we need an additional fflate build for this?

101arrowz · 2020-12-30T11:48:22Z

Yes, probably adding to fflate-deflate.js is the best solution.

Mugen87 · 2020-12-30T14:45:27Z

Yes, that sounds good. I vote to place this file in editor/js/libs as long as it is not required elsewhere.

Usage:

import { zipSync, strToU8 } from 'fflate';

const toZip = {};
// instead of zip.file(name, strData)
toZip[name] = strToU8(strData);
// instead of zip.file(name, arrayBufferData)
toZip[name] = new Uint8Array(arrayBufferData);
// instead of zip.file(name, uint8ArrayData)
toZip[name] = uint8ArrayData;

// If you have incompressible data (e.g. PNG file)
// set per-file options
toZip[name] = [uint8ArrayData, { level: 0 }];

// instead of zip.generate
const zipped = zipSync(toZip, {
  // You can change the level to 0 to not waste time
  // Better to use per-file options - this level only
  // has effect if no per-file options set
  level: 9
});

// to create a blob:
const zippedBlob = new Blob([zipped.buffer], {
  type: 'application/zip'
});

Side note: in case @sciecode is still working on this, fflate.unzlibSync(u8Data, new Uint8Array(uncompressedSize)) will work well for you. See the docs.

Also, if you're still looking into the EXR exporter, try fflateDeflate.zlibSync(u8Data, options). Docs

yep, still plan on finalizing the exporter. I had already taken a note to update current deflate to fflate's deflate, but thanks for the heads up 👍

@101arrowz rather than doing custom subset builds, would it make sense to do something like fflate-deflate.module.js, fflate-zip.module.js, fflate-gunzip.module.js, fflate-zlib.module.js, ...?

101arrowz · 2021-01-08T12:54:58Z

Not really, that wastes time just by HTTP overhead. Since ZIP and Zlib are literally a few hundred bytes different, it's worth bundling them together for reusability and if multiple examples are loaded with different API calls. If you worry about maintainability, unfortunately not much can be done unless NPM being required is OK.

mrdoob · 2021-01-08T16:11:59Z

I see. Okay, thanks!
