Here is my code:

const discord = require('discord.js');

const client = new discord.Client();

const guildId = '820368493017825333';

client.on('ready', async () => {

    console.log('ready');



    const commands = await client.api.

    applications(client.user.id)

    .guilds(guildId)

    .commands.get();

    console.log(commands);

});



client.login(require(`./config.json`).Token);

When it was accepted Discord haven't introduced truly /slash commands. So use the answer below, if you want to integrate or migrate to newest version of Discord.js

Well, the answer is pretty simple here. According to Discord.js docs, Class Client doesn't have api property. That's why you have the undefined error.

It seems like the tutorial that you are looking at is a bit outdated, or probably the tutor adds this property manually because Discord.js have relevant classes, like Application and ClientApplication but I still don't see an api property there as well.

If you are looking for a good guide, I might recommend you this one from the official Discord recommendation page.

If you want to implement commands to your Discord bot with slash support, just add the following code, after ready stage.

const prefix = '/'



client.on('message', message => {

    if (!message.content.startsWith(prefix) || message.author.bot) return;



    const args = message.content.slice(prefix.length).trim().split(/ +/);

    const command = args.shift().toLowerCase();



    if (command === 'ping') {

        message.channel.send('Pong.');

    }

})
