If you're absolutely sure that you want to allow MitM, this should work:
const Request = require('request'); const SteamCommunity = require('steamcommunity'); let community = new SteamCommunity({ "request": Request.defaults({"rejectUnauthorized": false}) });

Have you set the promptSteamGuardCode option to false?

The first problem I see is that you aren't handling the callback to offer.accept, which could fail.
 
Secondly, you can use the fs module to read from a file. If it's newline-delimited, you could call split("\n") to get an array containing each line in the file.

No, you'd need to use the WebAPI.

Do something like this:
let isEachItemATradingCard = theirItems.every((item) => { if (item.appid != 753 || item.contextid != 6) { // AppID is not "Steam" or contextid is not "Community" return false; } let tag = item.getTag('item_class'); if (!tag || tag.internal_name != 'item_class_2') { // Not a trading card                 // You could also check that tag.localized_tag_name == 'Trading Card' but that would only work for English return false; } return true; // all checks passed });

There's a separate secret that's used for confirmations; it's not the same as the one you use to login.

Added, sorry it took a while.

Automating reports/commendations is one thing I won't help with.

Not via any of my modules, you'd have to do it yourself.

Looks like maybe there was a condition which ended up in your Steam client connection being disconnected just before your web session was negotiated.

As you discovered, calling client.on('friendMessage#' + variable, ...) only creates a listener for the SteamID contained in variable at the time the listener was added. If you need to change the SteamID you're listening for, you need to just listen for friendMessage and check the SteamID in the event.

If you just use node-steamcommunity without any special parameters, it will act as if it's a mobile login.

You're setting the amount property on an array of CEconItem objects. It needs to be set on the objects themselves.

Please double-check the docs. Argument 2 to getProductInfo is an array of packages, not the callback. Pass an empty array if you don't care about any packages.
 
Also, it doesn't return the data; the data is passed to the callback.

When using Steam in-home streaming, network communication is encrypted with the auth secret. It's called a pre-shared key because it's an encryption key that is shared with both parties (in this instance, the machine the games are getting streamed from and the machine they're getting played on) by Steam, before the in-home connection is established.

The rate-limit is obviously not on your public IP. The change request is going through the proxy.

That's probably the case, yes.

You never defined any variable named community.

One of the files in your local cache appears to be corrupted. I'll push a fix to handle this case.

Like when you're logging in? Check the error event.

Yes, try/catch + isValid is the way you're supposed to validate a SteamID (also check the universe and type if you care about those).

client.setOption('promptSteamGuardCode', false);

Nope.

It executes once because you only told it to execute once.

No.
