node-steam-user VS node-globaloffensive

https://github.com/DoctorMcKay/node-steam-user is a popular NodeJS library for writing steam bots. This could provide useful, but iirc the method this uses for login will only allow you to have one login session at a time. Steam will automatically kick you out with a "logged in elsewhere" error.

Depends on what language you're using for JavaScript I think the defacto is anything Doctor McKay makes https://github.com/DoctorMcKay/node-steam-user, https://github.com/DoctorMcKay/node-steam-user etc. If you use python, I'd recommend https://github.com/Gobot1234/steam.py (I'm totally not biased). If you use C# then SteamKit is always a good option. If you use rust then SteamHelper looks interesting although doesn't support too many trading bot features

I don't know any direct resources for learning how the Steam network works, smart people figured it out over many years and lots of reverse engineering. I just know a few programming libraries which you can use to interact with it, the most popular two being Steam-User (JavaScript) and SteamKit2 (.NET).

One way you can do this, is by using the "steam user" node module node-steam-user. to play the games. And use the api call to Steam_Web_API to get the playtime of each of the games the account have.

you might have checked this out already, but just incase gonna drop this here: https://github.com/DoctorMcKay/node-globaloffensive, I think its gonna be hard af to implement in a web app but might be possible

Probably not the answer you were looking for, but if you're a programmer you can 100% program an app / a website that does that for you. There is a npm package called "globaloffensive" (https://www.npmjs.com/package/globaloffensive) that implements the methods "addToCasket" and "removeFromCasket" which lets you add / remove items from your storage unit. Maybe there are already some apps / websites that implemented stuff like that, but i dont know any of them.

From there you'll have to find a way to get floats from market items and sort the items, there're APIs for this but you can install extensions in the browser Selenium is using, whatever you get to work.

I guess you are referring to this package: https://github.com/DoctorMcKay/node-globaloffensive
