WebSocket Strange?

[rexwu1104]

I use WebSocket to connect this discord gateway, but on onmessage event it doesn't send me anything just a isTrusted property

Does that say: encoding=etf

etf is probably a typo, you probably meant utf8

[rexwu1104]

no, I use etf.js it is make from discord

[rexwu1104]

it is a encoding for discord, there have "json" and "etf"

[vinayakkulkarni]

what font is that @rexwu1104 ?

[rexwu1104]

If you use "json" directly for encoding, you will see these results directly

[rexwu1104]

I use "enoding=json" to try this code, but it still have bug. the discord send me the InvalidSession Event. it mean my packet is wrong, but my packet doesn't have any changes. so, I think it is the bug of WebSocket and the etf.js can't work perfect on bun.

this is the etf.js package url. https://www.npmjs.com/package/etf.js

@rexwu1104 If you have time, are you still seeing this issue on the latest version of Bun? bun upgrade

[rexwu1104]

there is a new error.

[rexwu1104]

it is from erlpack. and here is etf.js error.

This doesn't appear to be a WebSocket issue.

Code:

const ws = new WebSocket("wss://gateway.discord.gg/?encoding=json&v=10");
ws.addEventListener("message", ({ data }) => console.log(Buffer.from(data).toString()));

Output:

{"t":null,"s":null,"op":10,"d":{"heartbeat_interval":41250,"_trace":["[\"gateway-prd-us-east1-b-pn41\",{\"micros\":0.0}]"]}}

I did try using etf encoding with the etf.js package, but received the following error, Incompatible ETF version., which does not seem related to Bun.
