[HIVE Patched] SteemJS Full Tutorial - All The Functions - All The Abilities
[Hive Patched Tutorial] SteemJS - Vote, Comment and Follow functions - All In One
All of this tutorial is patched for Hive, so it works for steem and Hive!
All of the examples and results is from the old tutorial but still same for hive!
First things first, we need to set up the HTTP server, if you don't understand the code go to NodeJS #1 tutorial and check how it works!
const http = require('http');
const steem = require('steem-js-patched');
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);
});
steem.api.setOptions({ url: 'https://api.hive.blog' }); // Using HIVE API
your server runs at localhost:80 now.
to run the server use node server or whatever your script name is.
if you have nodemon use nodemon server.
Auto Follow Function
so we need to make the function, call it AutoFollower
function AutoFollower(user, tag, key, limit){
}
user - your account name, the username that going to make the auto-follow.
tag - the tag of the category you're going to follow the other accounts.
key - your posting private key.
limit - limit of the number of posts.
now we need to get the newest posts from your tag.
steem.api.getDiscussionsByCreated({tag: tag, limit: limit}, function(err, result){
if(!!err)
throw err;
result.forEach(function(row){
});
so firstly we have the function, this function gets the latest posts that posted with the tag and limit.
example: limit 1, tag: cryptocurrency, it will take the last post that posted on the cryptocurrency tag.
then we check if there is an error we send it to the console and close the app
if not we start a loop for the results.
inside of the loop create the variables
var follower = user;
var following = row.author;
var json = JSON.stringify(
['follow', {
follower: follower,
following: following,
what: ['blog']
}]);
follower - the follower username
following - the username that gets the follow
json - the array that gets all of the information for the follow function
now go for a second outside of the loop and create the variable
var count = 0;
and get back in the loop.
now we just need to send the following function
count+=5;
setTimeout(function(){
steem.broadcast.customJson(key, [], [follower], 'follow', json, function(err, result) {
console.log(err, result);
});}, count*1000);
so it's really simple, first, we adding 5 to the count variable, then we start timeout (timer) with the follow function.
we use the JSON variable that we made, the wif key and the follower name (our account).
and we set the timer to count*1000, it means that the timer is count(=5) seconds.
for example, I have the limit on 5
first, follow - after 5 seconds
second follow - after 10 seconds (but 5 seconds after the first follow)
etc.
now you can do 2 things,
first, you can leave it like that and let it work.
second, you can make a timer for every 30 minutes it will follow 10 users or even more.
so if you want the second way go with me
you need to make a timer for 30 minutes (or hour / less if you want) and run the function in a loop.
go to the end of the function and add this line
setTimeout(function(){AutoFollower(user, tag, key, limit)}, 30*60*1000);
it will make the function "stuck" in a loop because every time it runs it's running the timer again.
example: I run the function once, it will start the timer, when the timer ends it starts the function again and the function starts the timer. so it's a Loop.
and here you've done, just make four variables with the account name, wif key, post limit, and tag and start the function.
var user = "lonelywolf", tag = "cryptocurrency", key = "5AS4D685SA98AW4D89SA165", limit = 3;
AutoFollower(user, tag, key, limit);
it's going to work "forever" until you close the program.

const http = require('http');
const steem = require('steem');
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);
});
var user = "lonelywolf", tag = "cryptocurrency", key = "****", limit = 3;
AutoFollower(user, tag, key, limit);
function AutoFollower(user, tag, key, limit){
var count = 0;
steem.api.getDiscussionsByCreated({tag: tag, limit: limit}, function(err, result){
if(!!err)
throw err;
result.forEach(function(row){
var follower = user;
var following = row.author;
var json = JSON.stringify(
['follow', {
follower: follower,
following: following,
what: ['blog']
}]);
count+=5;
setTimeout(function(){
steem.broadcast.customJson(key, [], [follower], 'follow', json, function(err, result) {
console.log(err, result);
});}, count*1000);
});
});
setTimeout(function(){AutoFollower(user, tag, key, limit)}, 30*60*1000);
}

everything after null is the change in the block, that means it's the follow function works successfully.
