-A GitHub Account.
-A Heroku Account.

Difficulty

• Basic

Tutorial Contents

Creating your Bot on Discord:

Open the following link and login using your discord account: https://discordapp.com/developers/applications/me

Create a New Application.

Follow this instruction and Create a new application - Name Your App, Select an Avatar/Icon, and click "Create App."

Once the App is created, select it and Click on "Create a Bot User." Confirm and Choose "Yes. Do It!" on the box that pops up.

Make sure to take Note of the Client ID and Token. You will need these later when you begin programming your bot. Do not share this information!

Next you need to invite the Bot to your Discord Server using the following link:
https://discordapp.com/oauth2/authorize?&client_id=YOUR_CLIENT_ID_HERE&scope=bot&permissions=0

Replace YOUR_CLIENT_ID_HERE with the Client ID from your created Bot.

For a detailed walkthrough of this section, you can follow the following link:
https://github.com/reactiflux/discord-irc/wiki/Creating-a-discord-bot-&-getting-a-token

Creating the Script:

Go with the following link to GitHub to create the repository: https://github.com/new

Then we will create 3 scripts within that repository, which are these three

This will be our script to program both the bot and its function within discord:

bot.js

const Discord = require('discord.js');

const client = new Discord.Client();

 

client.on('ready', () => {

    console.log('I am ready!');

});

 

client.on('message', message => {

    if (message.content === 'ping') {

       message.reply('pong');

       }

});

 

// THIS  MUST  BE  THIS  WAY

client.login(process.env.BOT_TOKEN);//where BOT_TOKEN is the token of our bot

Our .Json file ,If you do not know what a json file is, you can google here

package.json

{

  "name": "Test",

  "description": "Test",

  "version": "0.0.0",

  "main": "bot.js",

  "scripts": {

    "start": "node bot.js"

  },

  "dependencies": {

    "discord.js": "11.1.0",

    "request": "2.81.0"

  }

}

And the Procfile

Procfile

worker: node bot.js

The scripts should appear like this

Note: if when copying the files or finishing the entire tutorial you have an error, try copying directly the GitHub script Found at the beginning of the post.

Uploading the Script to Heroku:

Heroku is a platform as a cloud computing service that supports different programming languages.

We will take advantage of that Heroku service to keep our bot activated

We will create a new board where the script will be uploaded here the link:
https://dashboard.heroku.com/apps

Let's go to the resources section and select github

Here we select our GitHub repository
we will select enable automatic desploy

Now we have to select what script we are going to work on, for that we go to resources and in free dynos we deselect the web and activate the worker

And our script would be online and working, but now we need to tell the script which bot is the one that is going to be linked to the script, that's why we go for settings

Then we will find an option called config variables,
add a new variable whose key will be BOT_TOKEN and the value of that variable will be the token of our bot

Then that would be everything, and the script knows what the bot is going to look for, here is a picture with the result of the tutorial we just made

And that would be all friends, the possibilities are endless when creating a discord bot, I will show you, a tutorial at the same time!

This is my first project.
