Lately, I enhanced my bot's functionality by allowing it to retrieve the color for embeds from a file specified in my config.json. All I need to do is modify something like:
"embedcolor": "00A950""embedcolor": "00000"-embedcolorset [HexCode] so that the bot can update the color value in the config file.
I appreciate any assistance on this matter :)
To read the content of a file, you can utilize the fs.readFile function and for writing data to a file (replacing it if already exists), you can use fs.writeFile.
If you need to verify a user-provided color, you can employ Util.resolveColor.
Ensure that you create a config.json file with at least an empty object ({}) to avoid receiving a SyntaxError.
Feel free to refer to the code snippet below:
const { Client, Util } = require('discord.js');
const fs = require('fs');
const path = require('path');
const TOKEN = 'BOT TOKEN';
const client = new Client();
const prefix = '!';
// Function to read JSON file
function jsonRead(filePath) {
return new Promise((resolve, reject) => {
fs.readFile(filePath, 'utf-8', (err, content) => {
if (err) {
reject(err);
} else {
try {
resolve(JSON.parse(content));
} catch (err) {
reject(err);
}
}
});
});
}
// Function to write JSON file
function jsonWrite(filePath, data) {
return new Promise((resolve, reject) => {
fs.writeFile(filePath, JSON.stringify(data), (err) => {
if (err) {
reject(err);
}
resolve(true);
});
});
}
client.on('message', async (msg) => {
const args = msg.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase();
if (command === 'embedcolorset') {
// Path to config.json file
// Assuming it's in the same folder as this file
const filePath = path.resolve(__dirname, './config.json');
// Check if provided colour is valid
if (isNaN(Util.resolveColor(args[0]))) {
return msg.channel.send('You need to provide a valid color');
}
try {
// Read file content, currently just a simple object
const config = await jsonRead(filePath);
// Update embedcolor property
config.embedcolor = args[0];
// Save file with updated settings
jsonWrite(filePath, config);
msg.channel.send(`Embed color set to ${config.embedcolor}`);
} catch (err) {
console.log(err);
}
}
});
client.once('ready', () => {
console.log('Bot connected...');
});
client.login(TOKEN);
When the condition operates alone, everything works fine. However, when I introduce an 'and' operation, it does not function correctly. If only one of them is true, the code works. It also successfully takes input values. <!DOCTYPE HTML Code ...
