Code from Previous Post
As promised, I will be putting the code here for those who just want to grab and go:
Your project directory:
│ .env
│ index.js
│ package-lock.json
│ package.json
│
├───commands
│ owo.js
│
├───events
│ ready.js
│
└───node_modules
│ ...
./.env
TOKEN=<your-token-here>
PREFIX=<your-bot-prefix>
./index.js
const { Client } = require('yuuko');
const path = require('path');
const dotenv = require('dotenv');
var env = dotenv.config();
env = process.env;
const bot = new Client({
token: env.TOKEN,
prefix: env.PREFIX,
ignoreBots: true,
});
bot.extendContext({
variableOne: 'Variable number 1!',
});
bot.editStatus('dnd'); // edits bot status
bot.on('error', (err) => {
console.error(err);
});
bot.globalCommandRequirements = {
guildOnly: true,
};
bot
.addDir(path.join(__dirname, 'commands'))
.addDir(path.join(__dirname, 'events'))
.connect();
./package.json
+ ./package-lock.json
I will not be showing this, but you should have yuuko
, eris
, and dotenv
installed.
./commands/owo.js
const { Command } = require('yuuko');
module.exports = new Command('owo', (message, args, context) => {
message.channel.createMessage('OwO');
});
./events/ready.js
const { EventListener } = require('yuuko');
module.exports = new EventListener('ready', ({client}) => {
console.log(`Logged in as ${client.user.usename}`);
});
That should be all the code for now.
The Meme
Command
Now, for the Meme
command! For this, we will need to get the memes from reddit. For that, we will be using got
to get the JSON from https://www.reddit.com/r/memes/random/.json
.
Install got
first:
npm i got --save
Create a file in ./commands
and name it meme.js
.
Put the following code inside (I will be explaining it later):
const { Command } = require('yuuko');
const got = require('got');
module.exports = new Command('meme', (message) => {
got('https://www.reddit.com/r/memes/random/.json')
.then((response) => {
const [list] = JSON.parse(response.body);
const [post] = list.data.children;
const permalink = post.data.permalink;
const memeUrl = `https://reddit.com${permalink}`;
const memeImage = post.data.url;
const memeTitle = post.data.title;
const memeUpvotes = post.data.ups;
const memeNumComments = post.data.num_comments;
message.channel.createMessage({
embed: {
title: memeTitle,
url: memeUrl,
image: {
url: memeImage,
},
color: 15267908,
footer: {
text: `👍 ${memeUpvotes} 💬 ${memeNumComments}`,
},
},
});
})
.catch(err => {
console.error(err);
});
});
Now start the project by navigating to the root folder of the project and running
node index.js
or if you have nodemon
installed
nodemon index.js
Let me break the code up into smaller pieces to explain it.
const { Command } = require('yuuko');
const got = require('got');
module.exports = new Command('meme', (message) => {
// code here
})
So, we first import the modules as usual, and create a command as we did before. Easy.
got('https://www.reddit.com/r/memes/random/.json').then((response) => {
// code here
}).catch(err => {
console.error(err);
});
Now, we use got
to get the JSON from reddit (the subreddit r/memes
actually), and save the response as the response
variable. Note that we are using Promises here, thus the .then().catch()
in the code. You can, however, use the async/await
in ES6.
Good?
const [list] = JSON.parse(response.body);
const [post] = list.data.children;
Now, we parse the response body by using JSON.parse
(Note: You will get an error if you just use JSON.parse(response)
), and get the information about the reddit post which we saved inside the post
variable. Understand? Excellent.
const permalink = post.data.permalink;
const memeUrl = `https://reddit.com${permalink}`;
const memeImage = post.data.url;
const memeTitle = post.data.title;
const memeUpvotes = post.data.ups;
const memeNumComments = post.data.num_comments;
Now we save the post url as memeUrl
, the meme image url as memeImage
, the meme title as memeTitle
, the number of meme upvotes as memeUpvotes
, and the number of comments as memeNumComments
.
message.channel.createMessage({
embed: {
title: memeTitle,
url: memeUrl,
image: {
url: memeImage,
},
color: 15267908,
footer: {
text: `👍 ${memeUpvotes} 💬 ${memeNumComments}`,
},
},
});
We then send the embed object. That's the end of it. Easy, right?
Conclusion
In this post, we used a REST API, and learnt how to send an embed in Eris. For my next post, I will be writing a whois
command. See you until next time!

Apparently
got
was updated to v12 and is ESM only, y'all will have to install specificallygot
version 11.
