Not working with Vite

[Armster15]

Hello,

I am using heic-decode, which underneath seems to be using libheif-js. I am currently using Vite.js for my project. However, upon importing the library, this error pops up in the console, preventing me from using the library:

The message on Firefox:

Uncaught TypeError: "stack" is read-only
    ensureErrnoError libheif.js:4153
    ensureErrnoError libheif.js:4151
    staticInit libheif.js:4157
    js libheif.js:7160
    js libheif.js:124105
    __require2 heic-decode.js:10
    js index.js:1
    __require2 heic-decode.js:10
    <anonymous> heic-decode:1

The message on Chrome:

Uncaught TypeError: Cannot assign to read only property 'stack' of object 'Error: No such file or directory'
    at libheif.js:4153:32
    at Array.forEach (<anonymous>)
    at Object.ensureErrnoError (libheif.js:4151:28)
    at Object.staticInit (libheif.js:4157:10)
    at Object.<anonymous> (libheif.js:7160:6)
    at node_modules/libheif-js/libheif/libheif.js (libheif.js:124105:3)
    at __require2 (heic-decode.js?v=6d7735c8:10:50)
    at node_modules/heic-decode/index.js (index.js:1:17)
    at __require2 (heic-decode.js?v=6d7735c8:10:50)
    at dep:heic-decode:1:16

Turning off minification, I was able to narrow down the error to this line in the built libheif-js file:

FS.genericErrors[code].stack = "<generic error, no stack>";

However, I am not sure how to fix this. I have been stuck on this issue for a while, so I would appreciate it if someone could take a look!

A reproducible repo with a very simple Vite project is available at https://github.com/Armster15/heic-decode-vite

Thank you for your time.

Using heic-convert (https://github.com/catdad-experiments/heic-convert) in node.js on a mac m1 or mac intel gives this error:

TypeError: Cannot assign to read only property 'stack' of object 'Error: No such file or directory'
    at ... /node_modules/libheif-js/libheif/libheif.js:1:161615

   ...

This occurs at the point of importing heic-convert, which loads libheif-js

const convert = require('heic-convert')

the package libheif.js vision maybe old, need upadte new vision. I fixed this bug https://github.com/lee-won/heic-convert-plus

Hi @lee-won, could you please share more details on how you managed to fix this bug?

I have solved this issue by forking libheif-emscripten.

1. Change the submodule libheif to a newer version with https://github.com/strukturag/libheif.git
2. In .github/workflows/emscripten.yml change to: EMSCRIPTEN_VERSION: 3.1.47 (for libheif v1.17.1)
3. Commit so that the workflow outputs an artifact libheif-dst, this contains a file libheif.js
4. Overwrite the content of libheif.js in node_modules/libheif-js using patch-package

I hope this helps someone

@catdad could you look into upgrading this library to work with libheif v1.17.1? Thanks in advance!

I've been looking at these changes as they are made to libheif itself. It looks like [email protected] is no longer API-compatible with [email protected] (the latest I have released). This change probably (total guess) happened when they converted the js module to use webassembly (at least I heard that happened, I have not verified anything). This is a positive change and all, but it will definitely be a complicated release for libheif-js... where node developers expect that huge breaking changes won't happen in minor version releases. I'll have to think a bit more about how to actually release this new version.

@merijnhofsteenge sorry this took a minute. Since the upstream libheif had a wasm version available, I took the time to make that available in libheif-js as well so everyone could get those benefits out of the box, and that added some complications.

The latest [email protected] is now built with emscripten 3.1.47 and uses the updated javascript wrapper, and it's available to install in npm. I have not tried to verify that it fixed the vite issue yet... I might do that later if one of y'all doesn't beat me to it.

Using Next.js this works! Thanks a bunch @catdad 😊

I am using heic-decode, everything works well
