Tutorial Contents

In this tutorial we will add two new command for our bot. Our first command will show the account follow and followers. Our second command will show the last vote date and time of the account.

New Command Account Follow and followers (accfow)

Now we will add a new command to see Steem account follow and followers.

Now, let's write the "else if" section of our command "app.js" file.

Code:

else if (msgorg.startsWith(prefix + 'accfow')) {

}

Now we will create a variable called "accountname". We will receive our message in this variable, and we will delete the "$accfow " section.

Code:

---

let accountname = msgorg.replace(prefix + 'accfow ','');

---

In this way we have successfully acquired steem account name.

Now we can create a request for follow and followers with steem.js.

Code:

---

steemjs.api.getFollowCountAsync((accountname),

function(err,fresult)

{

});

---

Okay, now I declare two variable "follower_count" and "following_count". And I am making assignments from our request.

Code:

---

var follower_count = fresult.follower_count;

var following_count = fresult.following_count;

---

Now I define message and send.

Code:

---

var follower_count = fresult.follower_count;

var following_count = fresult.following_count;

---

Now, I am adding "if invalid account id" part for invalid account names.

Code:

---

if(fresult["0"] === undefined)

{

console.log("Invalid Acccount ID");

message.channel.send('Invalid Acccount ID');

}

else

{

var follower_count = fresult.follower_count;

var following_count = fresult.following_count;

var accfow = (accountname + " Follower:" + (follower_count) + ' Following:' + following_count);

message.channel.send(accfow);

}

---

We say that if result (our account data) not defined, print "Invalid Acccount ID" message to our console and send the "Invalid Acccount ID" messsage to channel. Else get the account follow and followers info and send message.

All codes:

---

else if (msgorg.startsWith(prefix + 'accfow')) {

let accountname = msgorg.replace(prefix + 'accfow ','');

steemjs.api.getFollowCountAsync((accountname),

function(err,fresult)

{

if(fresult["0"] === undefined)

{

console.log("Invalid Acccount ID");

message.channel.send('Invalid Acccount ID');

}

else

{

var follower_count = fresult.follower_count;

var following_count = fresult.following_count;

var accfow = (accountname + " Follower:" + (follower_count) + ' Following:' + following_count);

message.channel.send(accfow);

}

});

}

---

In this code if received message is "$accfow steemaccountname" we will send the steemaccountname follower count and follow count message using our bot and Steem API.

We have integrate successfuly our bot into Steem account Follow and followers control.

---

New Command Account Last Vote (accltvote)

Now we are adding our second command to see the last vote date and time of the account.

Code:

else if (msgorg.startsWith(prefix + 'accltvote')) {

}

Now we will create a variable called "accountname". We will receive our message in this variable, and we will delete the "$accltvote " section.

Code:

let accountname = msgorg.replace(prefix + 'accltvote ','');

In this way we have successfully acquired steem account name.

Now we can create a request for account last vote date and time.

Code:

---

else if (msgorg.startsWith(prefix + 'accltvote')) {

let accountname = msgorg.replace(prefix + 'accltvote ','');

steemjs.api.getAccounts([accountname],

function(err,result)

{

if(result["0"] === undefined)

{

console.log("Invalid Acccount ID");

message.channel.send('Invalid Acccount ID');

}

else

{

var lastvote = moment(result[0].last_vote_time).add('hours', 3);

var lastvotemes = accountname + " Last Vote:" + (lastvote.format("YYYY-MM-DD HH:mm"));

message.channel.send(lastvotemes);

}

});

}

---

In our code above, we sent the api our steem account name. We created our request function to capture the incoming data (result). We say that if result (our account data) not defined, print "Invalid Acccount ID" message to our console and send the "Invalid Acccount ID" messsage to channel.
Else I get the date and time of the account last vote.And for Turkey UTC add 3 hours (you can customize it for yourself) and send "accountname + Last Vote: + (lastvote)" message.

In this code if received message is "$accltvote steemaccountname" we will send the steemaccountname last vote date and time message using our bot and Steem API.

We have integrate successfuly our bot into Steem account last vote date time control.

---

Run and test Parsbot

Okay, now we have to run and test our discord bot.

Open cmd and write "cd yourbotdirectory" and press enter. I write "cd C:\Users\gffdg\Desktop\Discord Pars Bot\parsbot".

Now we will run our app.js file with node.

node app.js

Our bot started successfully and printed "Pars Bot started" message on our ready event.

Discord:
