npm install steem --save)In this tutorial, you will learn how to make auto follow bot that follows every 5 minutes users by trending tag.
first, we want a function to make the follow,
create a function called AutoFollow, we need the function to set a timer for every 5 minutes.
function AutoFollow(name, tag, wif, limit){
}
name - the follower username, the username which sends the follow.
tag - the tag to get the posts from.
wif - the private posting wif key to send the follow.
limit - the limit number of the posts.
now let's get the posts and make a loop
steem.api.getDiscussionsByTrending({tag: tag, limit: limit}, function(err, result){
if(!!err)
throw err;
result.forEach(function(row){
});
getDiscussionsByTrending - this function will give the recent trending posts.
tag - the tag we get the posts from.
limit - the limit of the posts we get.
result.forEach - making a loop for the posts.
now we need some variables and a json variable
var follower = name;
var following = row.author;
var json = JSON.stringify(
['follow', {
follower: follower,
following: following,
what: ['blog']
}]);
follower - the follower username, the user who sends the follow.
following - the user you going to follow.
json - json variable for the follow function.
if we done all correctly just broadcast the follow with customJson function
steem.broadcast.customJson(wif, [], [follower], 'follow', json, function(err, result) {
console.log(err, result);
});
wif - the wif private posting key.
follower - the follower name (you).
follow - the role of the customJson function.
json - the json variable that contains the follower name, following name and the type of blog.
now we want to send the function every 5 minutes (or any time else)
setTimeout(function(){AutoFollow("lonelywolf", "dtube", "XXXX", 1)}, 5*60*1000);
lonelywolf - the username.
dtube - the tag.
XXX - wif key (private posting key).
1 - the limit of posts.
5*60*1000 - 5, minutes. 60, seconds. 1000, milliseconds.
the full function code
function AutoFollow(name, tag, wif, limit){
steem.api.getDiscussionsByTrending({tag: tag, limit: limit}, function(err, result){
if(!!err)
throw err;
result.forEach(function(row){
var follower = name;
var following = row.author;
var json = JSON.stringify(
['follow', {
follower: follower,
following: following,
what: ['blog']
}]);
steem.broadcast.customJson(wif, [], [follower], 'follow', json, function(err, result) {
console.log(err, result);
});
});
setTimeout(function(){AutoFollow("lonelywolf", "dtube", "XXX", 1)}, 5*60*1000);
});
}
if we done all correctly we can send the function when the script starts
AutoFollow("lonelywolf", "dtube", "XXX", 1);
and we will see that result
(the script run for 15 minutes now, so I followed 3 users already)
