Creating Follow Bot w/ NodeJS

<h2>Introduction <p dir="auto">This tutorial will show you how to automatically follow users with a bot. <p dir="auto"><span>First, you will need to set-up a NodeJS development environment. You can follow along the tutorial at <a href="https://steemit.com/javascript/@money-dreamer/nodejs-steemit-bot-tutorial" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">https://steemit.com/javascript/@money-dreamer/nodejs-steemit-bot-tutorial if you need to. That tutorial is a pre-requisite for this tutorial unless if you are already familiar with JavaScript, NodeJS, GIT and the Steemit API. <p dir="auto"><span>You can view the full source code at: <a href="https://github.com/AdamCox9/Steemit-Follow-Bot" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">https://github.com/AdamCox9/Steemit-Follow-Bot <p dir="auto">After getting your development environment set-up, copy and paste this code into a file named <code>follow_trending_authors.js and execute it like <code>node follow_trending_authors.js from a terminal as described in the previous tutorial. This will bring in all the functions from the Steem library, set the user/pass and create a log-in session to the Steem blockchain. The followingArray saves the new account so no duplicate following attempts. <pre><code>var steem = require('steem'); var username = 'ENTER_USERNAME_HERE'; var password = 'ENTER_PASSWORD_HERE'; var wif = steem.auth.toWif(username, password, 'posting'); var followingArray = []; <p dir="auto"><br /> <p dir="auto">Let's get the trending categories in our initial call. You can view the data printed to the console to become familiar with it. <pre><code>steem.api.getState('/trending', function(err, result) { console.log(err, result); ... }); <p dir="auto"><br /> <p dir="auto">The <code>sleep function will time out the script so it does not make requests too fast: <pre><code> function sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } <p dir="auto"><br /> <p dir="auto">Create a function that will loop over the accounts in the trending tag: <pre><code> async function followAccountsInTrending(result) { var content = result.content; var accounts = result.accounts; for(var attributename in accounts) { //console.log(attributename+': '+accounts[attributename]); var following = accounts[attributename].name; let followReq = ['follow'] followReq.push({follower: username, following: following, what: ['blog']}) const customJson = JSON.stringify(followReq) console.log( followReq ); followingArray.indexOf(following) === -1 ? followingArray.push(following) : console.log('This item already exists'); steem.broadcast.customJsonAsync(wif, [], [username], 'follow', customJson) .then(console.log) .catch(console.log) await sleep(30000); console.log( followingArray ); } } <p dir="auto"><br /> <p dir="auto">Create a function that loops over each category: <pre><code> async function startFollowAccountsInTrending(result) { var trending_tags = result.tag_idx.trending; for(var attributename in trending_tags) { console.log(attributename+': '+trending_tags[attributename]); steem.api.getState('/trending/'+trending_tags[attributename], function(err, result) { followAccountsInTrending(result); }); await sleep(30000); } } <p dir="auto"><br /> <p dir="auto">Initialize the function to loop through the categories: <pre><code> startFollowAccountsInTrending(result); <h2>Further Development <p dir="auto">It will allow you to set parameters to select who to follow. Some of these parameters will be: <ul> <li>SBD/STEEM Balance <li>Reputation <li>Number of Followers <li>Number of Following <li>Total Author Rewards <li>Total Curation Rewards <p dir="auto"><span>You can view the full source code at: <a href="https://github.com/AdamCox9/Steemit-Follow-Bot" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">https://github.com/AdamCox9/Steemit-Follow-Bot <p dir="auto">Proof of Work: <p dir="auto"><img src="https://images.hive.blog/768x0/https://steemitimages.com/DQmbuecZSkSZRYAtSt4NMiu3iyBkF28sRJFqCCs11ieivK9/image.png" srcset="https://images.hive.blog/768x0/https://steemitimages.com/DQmbuecZSkSZRYAtSt4NMiu3iyBkF28sRJFqCCs11ieivK9/image.png 1x, https://images.hive.blog/1536x0/https://steemitimages.com/DQmbuecZSkSZRYAtSt4NMiu3iyBkF28sRJFqCCs11ieivK9/image.png 2x" /> <p dir="auto"><a href="https://steemit.com/javascript/@money-dreamer/nodejs-steemit-bot-tutorial" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">Previous | <a href="https://steemit.com/utopian-io/@money-dreamer/deep-follow-nodejs-steemjs" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">Next <p dir="auto"><br /><hr /><em>Posted on <a href="https://utopian.io/utopian-io/@money-dreamer/creating-follow-bot-w-nodejs" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">Utopian.io - Rewarding Open Source Contributors<hr /><p>
