The Tutorial

Step 1 - create a function

you need to create a function to be able to get this function loop every 30 minutes, so we want to make a function called ClaimRewards

function ClaimRewards(account_name, wif){

}

this will give us the ability to call the function when we set up the loop,

account_name - the account that we claiming the rewards.

wif - the private posting key of the account

Step 2 - Get Account Information (sbd, steem, and sp that we need to claim)

  steem.api.getAccounts([account_name], 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);
  }

sbd - the amount of rewarded sbd we need to claim.

steem - the amount of rewarded steem we need to claim.

sp - the amount of rewarded vesting (invested steem) or Steem power we need to claim.

the result of the console

0.000 SBD 0.000 STEEM 0.000000 VESTS

currently, I have no rewards to claim so It's giving 0.

Step 3 - Check if there are rewards to claim

to check if there are rewards we need to check for "0" value in any type of reward.

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

at the else, we will claim the rewards at the next step

result

0.000 SBD 0.000 STEEM 0.000000 VESTS
No Rewards To Claim!

Step 4 - Claiming the rewards

when we have all of the variables we need we can now claim the rewards

  steem.broadcast.claimRewardBalance(wif, account_name, 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);
  });

wif - the private key of the account

account_name - the account that we claiming the rewards.

sbd, steem_liquid, sp - the reward values as sbd, steem liquid and steem invested(Sp).

and then we sending the information to the console.

result

Rewards of @lonelywolf Have Been Claimed To The Wallet!
Result:
undefined

if you get undefined and the rewards claim value is 0.000 SBD 0.000 STEEM 0.000000 VESTS it's okay because there are no rewards and the function need more then 0 to claim the rewards.

Step 5 - Set up the timer(loop)

at the end of the claimRewardBalance function, we want to add this line

setTimeout(function(){ClaimRewards(account_name, wif)}, 30*60*1000);

wif - the private key of the account

account_name - the account that we claiming the rewards.

30*60*1000 - 30 is the minutes (you can change it to 60 or 120 for 1 or 2 hours), 60 is the seconds, 1000 is the milliseconds.

full code of the function

function ClaimRewards(account_name, wif){
  steem.api.getAccounts([account_name], 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(wif, account_name, 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);
  setTimeout(function(){ClaimRewards(account_name, wif)}, 30*60*1000);
  });
  });
}

Step 6 - Claim The Rewards

at the start of the script create 2 variables, the wif and the account_name

const account_name = "lonelywolf", wif = "5XXXXXXXXXXX";

and then you can claim the rewards and every 30 minutes (or what you changed it to) it will claim the rewards again.

ClaimRewards(account_name, wif);

if all done correctly you will get this results

no rewards to claim

0.000 SBD 0.000 STEEM 0.000000 VESTS
No Rewards To Claim!

reward claiming

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

if you have something to claim undefined will not be there and you will get a different result.
