Version 3.0.0 always appears an error in the mobile browser: TypeError: Symbol.dispose is not defined. #260
Description
Activity
I have the same bug. If I may join this bug report. I just updated from v3.0.0-beta3 to v3.0.0
I'm seeing this issue on
Firefox 135.0 (64-bit) (Linux, Fedora), but not onChromium Version 132.0.6834.159 (Official Build) (64-bit). Seems likeSymbol.disposeisn't supported on Firefox, yet.Uncaught (in promise) TypeError: Symbol.dispose is not defined. __addDisposableResource2 @msgpack_msgpack.js:872 decodeAsync Decoder.ts:349 decodeAsync decodeAsync.ts:17 ...Here is the relevant section:
msgpack-javascript/src/Decoder.ts
Lines 295 to 302 in 130ea87
I wonder if the wrong syntax is being used, in the typescript docs they use
[Symbol.dispose]() { ... }
Instead of
[Symbol.dispose]: () => { ... }
I am out of time to look at this today, tomorrow I could look deeper.
Falling back to
v3.0.0-beta4is a work-around.Will fix it, but I reccomend using core-js or something equivalent.

v3.0.0-beta4Yes, I went back to 2.8.0. Since the CDN URL will be redirected to the latest version of MsgPack (3.0.0), I now only dare to put the 2.8.0 min.js directly into my js folder
Released a new version 3.0.1 to fix this issue.

on Feb 21, 2025 Unfortunately even in
3.0.1this is still an issue.To make matters worse it seems to be browser version sensitive.
I can not pinpoint the exact adjacent browser versions where it will crash in version A but work fine in version B
but at least I know that in
112.0.0.0and in118.0.5993.129it crashes
but in130.0.6723.152and133.0.0.0it works finePlease, reopen the ticket if possible
Just adding another sample. I see this issue in
3.1.0
Interestingly not in
3.0.0-beta3.Browser: Firefox on mac 135.0.1 (aarch64)
Version 3.0.0-beta4 uses Explicit Resource Management, a feature that not only is not yet supported in popular browsers, but also is not yet even finalized.
The only correct solution is removing any usage of this feature. See #267.
Reacted by Simon and Russell McClellanThis is still broken for me on 3.1.0 on Safari 18.3
Fix submitted, waiting for review.

demo:
wsClient.onmessage = async function (evt) {
let parseData;
const decompressedData = pako.inflate(await evt.data.arrayBuffer());
