Introduction:
Discord bots are fun to make because you can experiment with a lot of new things there. You're given a platform "Discord" and you integrate with almost all the tools available out there.
Let's start with the Prerequisites:
- Node.js and npm installed in mac/windows
-
Create a new directory name it "pokemon-discordo" or anything you like :D
npm init -y -
Open your cli/terminal/cmd we're installing three dependencies:
- Discord.js for using discords API with Nodejs. This will help us to code our bot.
- dotenv is a package we use to store our tokens and API keys so that we don't accidentally share them on GitHub. **node-fetch* a light-weight module that brings window.fetch to Node.js
npm install discord.js dotenv node-fetch -
We'll also use nodemon, which helps you to load your changes continuously with changes in your files eg: JavaScript, JSON, Html/CSS, etc except ".env".
npm i -g nodemon
Let's Start Coding
-
Create a new js file "bot.js" and include all the libraries in it.
const Discord = require('discord.js'); require('dotenv').config(); const fetch = require('node-fetch'); -
Now let's declare our URL for the API and our bot object, in discord.js we have a way to do things if you want to include something you can include the class declared in the lib
const URL = 'https://pokeapi.co/api/v2/pokemon'; const bot = new Discord.Client(); -
Discord.Client class has a lot of event listeners we are going to use "ready" and "message" in our bot.
bot.on('ready', () => { console.log('Bot is up and running!'); }); bot.on('message', async (message) => { // some code }) -
Let's add some code in our 'message' event listener, so essentially we want to listen to messages, and as soon as a message is starting with "pokemon" FYI(this message we're listening to is from a user who is using the bot on a server or directly talking to the bot).
bot.on('message', async (message) => { if (message.content.startsWith('pokemon')) { const messageArray = message.content.split(' '); const result = await fetch(URL + `/${messageArray[1]}`); const data = await result.json(); const helpEmbedd = new Discord.MessageEmbed() .setTitle(`Name: ${data.name}`) .setImage(`${data.sprites.front_default}`); message.reply(helpEmbedd); } });
In the above code:
a. We're taking the string after pokemon for eg: pokemon Pikachu, the above code will send this name Pikachu to pokemon API and send back its information in response.
b. Further, the code will take out front_default from the response provided by pokemon API.
c. And this response is sent in message.embed form message.channel.send to the channel where the data was requested for.
- Let's now add our code to our bot token:
a. Go to https://discord.com/developers/applications
b. Open your newly created application
c. Click on BOT
d. Click on create your bot
e. Get your TOKEN :D
Create a new file ".env" and paste your bot token
BOT_TOKEN=<--YOUR BOT TOKEN-->
f. In your bot.js file
bot.login(`${process.env.BOT_TOKEN}`);
Full bot.js Code:
require('dotenv').config();
const fetch = require('node-fetch');
const Discord = require('discord.js');
const URL = 'https://pokeapi.co/api/v2/pokemon';
const bot = new Discord.Client();
bot.on('ready', () => {
console.log('Bot is up and running!');
});
bot.on('message', async (message) => {
if (message.content.startsWith('pokemon')) {
const messageArray = message.content.split(' ');
const result = await fetch(URL + `/${messageArray[1]}`);
const data = await result.json();
const helpEmbedd = new Discord.MessageEmbed()
.setTitle(`Name: ${data.name}`)
.setImage(`${data.sprites.front_default}`);
message.reply(helpEmbedd);
}
});
bot.login(`${process.env.BOT_TOKEN}`);

Full Repo
Pokemon Discord Bot
Introduction
Learn to build a Discord bot using Discord.js. This repository will help you get started with building a Discord bot that fetches data from the Pokemon API.
The bot listens to the command pokemon and fetches the infromation of the Pokemon specified after the command.

BOT_TOKEN=<--YOUR BOT TOKEN-->
5. Start the Bot
yarn start
or
npm start
Make sure to add your bot to a server or open a direct message with it, to test the functionalities.

We created this bot on a Twitch live stream! If you want to learn from the start you can checkout…
The Recording for the Twitch Live is available: Youtube
PS: Add your bot to your server and ask your friends to suggest some cute Pokemon :D
