The Tutorial

So because I already made a tutorial about that I will "skip" this part of making a basic server and I'll just give it.

const http = require('http');
const port = 80; //you can use any other port, like 3000 or something.
const hostIP = "localhost"; //or "127.0.0.1" which is better for you.

const server = http.createServer((req, res) => {
res.statusCode = 200;

res.setHeader('Content-type', 'text-plain');

res.end('Hello World! this is my first project at node.js!');

});

server.listen(port, hostIP, () => {

console.log("Listen to port " + port);

});

just to make it easy, we're making a basic server and make a listen to the port (currently 80) and to our localhost server.
for this bot, we don't need anything better than that.

now we're going to make the claim function

so make a new function called ClaimMyRewards with the vars account and key

function ClaimMyRewards(account, key){

}

account - the account name
key - the private active key

now we need to get the information about the account

  steem.api.getAccounts([account], function(err, result){
  const sbd = result[0].reward_sbd_balance,
  steem_liquid = result[0].reward_steem_balance,
  sp = result[0].reward_vesting_balance;
  console.log(sbd + " " + steem_liquid + " " + sp);
  }

first, we're getting the account json variable(all of the information of the user) with the function getAccounts
then we're making a variable that called sbd and we're getting the variable "reward_sbd_balance" this variable is the balance of the unclaimed rewards of SBD
same for steem and SP

then we're sending it to the console (the info)

now we're going to check if there are any rewards to claim

 if(sbd == "0.000 SBD" && steem_liquid == "0.000 STEEM" && sp == "0.000000 VESTS"){
  console.log("No Rewards To Claim!");
  }else{//claiming rewards
  }

if the sbd & steem & sp is equal to 0, that means there is nothing to claim
the console will tell us that there is nothing to claim

if there is anything to claim we'll make the claim

steem.broadcast.claimRewardBalance(key, account, steem_liquid, sbd, sp, function(err, result) {
  console.log("Rewards of @" + account_name + " Have Been Claimed To The Wallet!");
  console.log("Result:");
  console.log(result);
  });

so, we're using the functionclaimrewardsbalance this function making a claim for the rewards that unclaimed on your account
it needs the key and the account and the steem, sbd, sp balance(amount) to make the claim.

if there are no errors it will send the comments to the console

now we're done with this function and we only need to make a timer that goes every 120m (2hrs) and uses this function

first make 2 variables, one called account and second key

example :

const account = 'lonelywolf', key = 'P5K123N1UO23NU1B412U04N1U024';

note: you need to use an Active Key and not Posting Key to make a claim!

now we just need to make the timer

go to the bottom of the function (claimmyrewards)
and paste that

setTimeout(function(){ClaimRewards(account, key)}, 120*60*1000);

it will make a timer 2 hours from now (when the function runs) and use the function again , it will make a loop.

now just at the bottom/middle of the script use this row:

ClaimRewards(account, key);

results:

• no rewards

0.000 SBD 0.000 STEEM 0.000000 VESTS
No Rewards To Claim!

• claimed rewards

0.000 SBD 0.000 STEEM 0.000000 VESTS
Rewards of @lonelywolf Have Been Claimed To The Wallet!
Result:
undefined

undefined means that no result found (or no errors).

• full code

const http = require('http');
const port = 80; //you can use any other port, like 3000 or something.
const hostIP = "localhost"; //or "127.0.0.1" which is better for you.

const server = http.createServer((req, res) => {
res.statusCode = 200;

res.setHeader('Content-type', 'text-plain');

res.end('Hello World! this is my first project at node.js!');

});

server.listen(port, hostIP, () => {

console.log("Listen to port " + port);

});
const account = "lonelywolf",
  key = "P5ASDNANDPOPASDNOPDN1231312";

ClaimRewards(account, key);

function ClaimRewards(account, key){
  steem.api.getAccounts([account], function(err, result){
  const sbd = result[0].reward_sbd_balance,
  steem_liquid = result[0].reward_steem_balance,
  sp = result[0].reward_vesting_balance;
  console.log(sbd + " " + steem_liquid + " " + sp);
  steem.broadcast.claimRewardBalance(key, account, steem_liquid, sbd, sp, function(err, result) {
  console.log("Rewards of @" + account + " Have Been Claimed To The Wallet!");
  console.log("Result:");
  console.log(result);
  setTimeout(function(){ClaimRewards(account, key)}, 120*60*1000);
  });
  });
}
