Need some help about checking Steam level

[TextDynasty]

So I planned to write a script for the bot to have a background check.

const SteamUser = require('steam-user');

var client = new SteamUser();

var steamid = '76561198302774496';

client.getSteamLevels([steamid], function(results){
    console.log(results);
})

However, it didn't show the results to the console.

It doesn't look like you ever logged on.

Oh yeah I forgot to log in. But after login, there's still nothing in the console.

const SteamUser = require('steam-user');
const SteamTotp = require('steam-totp');

const config = require('./config');

var client = new SteamUser();

const logOnOptions = {
    accountName: config.accountName,
    password: config.password,
    twoFactorCode: SteamTotp.generateAuthCode(config.shared_secret)
};
client.logOn(logOnOptions);

client.getSteamLevels(['76561198302774496'], function(results){
    console.log(results);
})

You seem to not have an understanding of how async JavaScript code works. Just because logOn was called doesn't mean you're actually logged on. You need to wait for the loggedOn event.

I edited it a bit

const SteamUser = require('steam-user');
const SteamTotp = require('steam-totp');

const config = require('./config');

var client = new SteamUser();

const logOnOptions = {
    accountName: config.accountName,
    password: config.password,
    twoFactorCode: SteamTotp.generateAuthCode(config.shared_secret)
};
client.logOn(logOnOptions);
client.on('loggedOn', () => {
    var steamid = '76561198302774496';
    client.setPersona(1);
    console.log('LogOn');
    
    client.getSteamLevels([steamid], function(requests){
        var level = requests.steamid;
        console.log(level); //console.log(requests); works fine but I want it to show the level of the steamid only
    })
});

Solved

const SteamUser = require('steam-user');
const SteamTotp = require('steam-totp');

const config = require('./config');

var client = new SteamUser();
var steamid = ''; //SteamID64 you want to check

const logOnOptions = {
    accountName: config.accountName,
    password: config.password,
    twoFactorCode: SteamTotp.generateAuthCode(config.shared_secret)
};
client.logOn(logOnOptions);

client.on('loggedOn', () => {
    client.setPersona(1);
    console.log('LogOn');
    client.getSteamLevels([steamid], function(requests){
        var level = requests[steamid];
        console.log(level);
    })
});

How many users can I check at once?

 

Can I, for example, get the levels of all users on my friends list or it is not recommended?
