Также вы можете сделать это так, добавить / изменить переменную конфигурации и затем сохранить ее.
const fs = require('fs');
const config = require('../config.json')
const Discord = require('discord.js');
const client = new Discord.Client();
module.exports.run = async (client, message, args) => {
let owner = process.env.OWNER.split(',')
if(!owner.includes(message.author.id)) return message.reply("This command is not made for everyone")
if (message.channel.type === "dm" || message.author.bot || message.author === client.user) return; // Checks if we're on DMs, or the Author is a Bot, or the Author is our Bot, stop.
if (args.length === 0) return message.reply('Pls mention a channell')
let targetChannel = message.mentions.channels.first() || message.guild.channels.get(args[0])
if (!targetChannel) return message.reply('Cant fin`d channel')
config.channed_id = targetChannel.id
fs.writeFile('./config.json',JSON.stringify(config) , (err) => {
if (err) console.log(err);
message.channel.send("Done")
})
}
exports.help = {
name: "wtp",
category: "General",
description: "Add this channel into WTP",
usage: "wtp <channel_id>"
};
