How do I fix ReferenceError: command is not defined - discord.js

I'm trying to make a discord bot and I get the error "ReferenceError: command is not defined" I don't understand why, can someone help?
heres my code:
console.clear();
const Discord = require('discord.js');
const client = new Discord.Client({ intents: ['GUILDS', 'GUILD_MESSAGES']});
const Client = require("./Structures/Client.js");
const config = require("./Data/config.json");
client.commands = new Discord.Collection();
const fs = require("fs");
fs.readdirSync("./src/Commands")
.filter((file) => file.endsWith(".js"))
.forEach((file) => {
/**
* #type {Command}
*/
const commands = require(`./Commands/${file}`);
console.log(`Command ${command.name} loaded`);
client.commands.set(command.name, command);
});
client.on("ready", () => console.log("SpidBot is online!"));
client.on("messageCreate", (message) => {
//console.log(message.content);
//if (message.content == "!Spid") message.reply("Hello!");
if (!message.content.startsWith(config.prefix)) return;
const args = message.content.substring(config.prefix.length).split(/ +/);
const command = client.commands.find((cmd) => cmd.name == args[0]);
});
client.login(config.token);
heres the error:
C:\Users\Aly\Desktop\SpidBot\src\index.js:22
console.log(`Command ${command.name} loaded`);

It appears theres some more errors, so can someone help me fix it?

You accidentally misspelt the variable name on line 21:
const commands = require(`./Commands/${file}`);
You named the variable "commands". Simply remove the 's' and it should work.
So it should be:
const command = require(`./Commands/${file}`);

CLIENT_MISSING_INTENTS with d.js

const Discord = require('discord.js');
const bot = new Discord.Client();
const client = new Client({
disableMentions: "everyone",
ws: {
intents: ["GUILDS", "GUILD_MEMBERS", "GUILD_MESSAGES", "GUILD_PRESENCES"]
}
})
const token = 'my token';
bot.on('ready', () =>{
console.log('This bot is online!')
})
bot.login(token)
when I run "node ." this results in this error. I don't really understand it as I added intents?

I'm new to this so please be kind when you find my obvious flaw.
Thanks in advance!
Intents is new thing that came as requirement in v13 now you have few issues in your intents but that is great start. You would need to define intents following way:
const { Client, Intents } = require("discord.js");
client = new Client({
intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES, Intents.FLAGS.GUILD_MEMBERS, Intents.FLAGS.GUILD_PRESENCES]
});

INDEX.JS

const socketio = require('socket.io');
const http = require('http');
const PORT = process.env.PORT || 5000;

app.use(router);
server.listen(PORT, () => console.log(`Server has started on port ${PORT}`));
Can someone help me with these?
According to https://expressjs.com/en/guide/routing.html you need to provide a route where the imported router is support to run. Try:
app.use('/', router);
or you can use a different route, like /mysubroute.

Koa start error

const { res } = this;

When I start my koa demo, console shows this.
node version: v4.4.7
"koa": "^2.2.0"
Here is my entry.js:
const Koa = require('koa');
const app = new Koa();
app.use(ctx => {
ctx.body = 'Hello Koa';
});
app.listen(3000);
After I remove {} in response.js:47 and context.js:124
const res = this;
everything runs ok.I don't know why.
Because const res = this; mean just constant variable res equals this but
const { res } = this; is object destructuring (http://exploringjs.com/es6/ch_destructuring.html) it's equal const res = this.res; So if this has not property res you'll receive error.
