Whether it's creating a discord gaming server or a community server you need some type of moderator to maintain and keep control of the chaos. This might be in the form of blocking inappropriate text or images which can be a big problem if the server is for children.
so, the question is how do we do it? there are two ways to do this
1) hire a moderator and pay them
2) create a bot that can do all of the same things if the better and the cost is $0
let's do option 2 it's much more effective and cost-efficient
Introduction
so we are going to use node.js with the discord.js library to interact with discord API
so let's first initialize a package.json
npm init
running this command will ask a bunch of questions for the project, so enter the correct details for the project and let's get into the next step
create a javascript file called index.js and in the package.json add the following to the scripts
"scripts": {
start: 'node index.js'
},
now, let's install the necessary libraries
npm i discord.js --save
this is going to be for development so install it as a dev dependency.
npm i nodemon --save-dev
now let's add another development script to the scripts in package.json
"scripts": {
dev: 'nodemon index.js'
},
Let's Get Started
in the index.js file import the discord library to use it in our codebase
const discord = require('discord.js');
then let's create a constant called client which will contain the discord client object which represents the bot.
const client = new discord.Client({
intents: [
Intents.FLAGS.GUILDS,
Intents.FLAGS.GUILD_MESSAGES
]
})
whenever someone sends a message or when the bot joins it's called an event.
user1 ==> sends message ==> event sent
each event has a name that represents its function like onMesssage and ready which only runs when a user send's a message or when the bot joins!.
We can also give a callback function that runs when the event is sent.
We can look if someone has posted something by using the onMessage event which will run when someone sends a message with all the details of the message sent
//logging when ready
client.on('ready', () => {
console.log('π€π€ Bot is ready to login');
console.log(`Logged in as ${client.user.tag}!`);
});
we, need to install the bad-words package which will detect bad words in the messages
npm i bad-words
const Filter = require('bad-words')
client.on('messageCreate', async (message) => {
const filter = new Filter();
if (filter.isProfane(message.content)) {
message.delete();
message.channel.send(
`${message.author.username} you are not allowed to use that
word.`
);
}
})
now we have the get the discord token and use this line of code to initialize our bot
client.login(process.env.DISCORD_TOKEN);
to add nudity detection in images we can use this API.
click on login if you have an account or get started if you don't have an account enter your email and password
go to the API key's section and copy the API use token and the API secret
also, install Axios to send and fetch data for the NSFW verification
npm i axios
after that's done let's do a request...
now here we need to pass in a URL to send it for review
axios.get(
'https://api.sightengine.com/1.0/check.json',
{
params: {
url,
models: 'nudity,wad,gore',
api_user: API_USER,
api_secret: API_SECRET,
},
}
);
to get the user's attachment file let's see if the user has one
and then extract the URL parameter from the message which contains the image sent by the user
client.on('messageCreate', async (message) => {
//checking if the user has a attachmnet
if (message.attachments.size > 0) {
//send the picture url for review using the api
//message.attachments.first().url --> url of the image sent by the user
const { data } = await axios.get(
'https://api.sightengine.com/1.0/check.json',
{
params: {
message.attachments.first().url,
models: 'nudity,wad,gore',
api_user: API_USER,
api_secret: API_SECRET,
},
}
);
}
})
insert this code inside the if condition to delete the message and send an alert message
if (
data.weapon > 0.01 ||
data.alcohol > 0.1 ||
data.gore.prob > 0.1 ||
data.nudity.safe < 0.9
) {
message.channel.send(
`${message.author} Please do not post nudity or gore content.`
);
message.delete()
}
finally its ready! run npm run dev to see the results and all the messages that are inappropriate video messages etc.
signing off...
