Slash Commands in Discord.js

These are some simple examples for using Slash Commands in discord.js.
discord.js doesn't have full support for slash commands yet (there's a wip pr) but you can still use the underlying api and websocket to use them.
Note that discord.js doesn't officially support using client.api, this is basically just a workaround until they fully release support.

Please read Discord's Slash Command docs since they have actual docs and details for slash commands; the code examples below are just how you can implement it using discord.js.

Note that slash commands won't show in a server unless that server has authorized it with the applications.commands oauth2 scope (not just the bot scope).

Registering a Command:

You only need to register each command one time. You might wanna use an eval command for this.

Send a Command object

Global Commands

global commands show in all authorized servers, but take up to an hour to deploy.

// if your application id and bot id are different, change client.user.id to the application id
client.api.applications(client.user.id).commands.post({data: {
    name: 'ping',
    description: 'ping pong!'
}})

Guild-specific commands

guild commands deploy immediately - use these for testing

// if your application id and bot id are different, change client.user.id to the application id
client.api.applications(client.user.id).guilds('guild id').commands.post({data: {
    name: 'ping',
    description: 'ping pong!'
}})

Receiving the Event

interaction is an Interaction object

client.ws.on("INTERACTION_CREATE", async interaction => {
  
})

Responding To An Interaction:

send an Interaction Response object

client.api.interactions(interaction.id, interaction.token).callback.post({data: {
  type: 4,
  data: {
    content: 'hello world!'
    }
  }
})

discordjs/discord.js#5448

It's done.

We all know that, it's written on top of the gist and I have the repo on follow
I just wanna know what I did wrong for informational purposes, I'm already using djs master

@AndrewDaGuy use client.api.applications(client.user.id).commands.get() to get the command list with IDs, then client.api.applications(client.user.id).commands('id').delete() to delete a command

@advaith1 I teied using the .get method and end the message, but supposedly it's an empty message, even though I do have commands set up.

@YodaLightsabr no

Update: A week ago they fixed it so now you can set private messages with embeds

How can I get the data of the channel where the slash command is used? Like message.channel

@radston12

This worked for me client.channels.fetch(interaction.channel_id)

I updated my code for my bot and I'm facing an issue where it shows duplicate slash commands. Anyone else facing this issue? I think it might be because of how discord stores cache. I'm not sure. Would appreciate any help. Thanks.

If you have guild and global commands it will show as two commands, even if they have the same options and name and description.

Hey, attaching images to embeds that are sent back as a part of an interaction doesn't seem to working. Is this a limitation of slash commands as of now?

@DragonZV
Copy link

it isn't, djs's master branch allows it. I'm not sure why we can't send it via advaith's method though.

I haven't had any luck with sending a picture file and referencing it from the embed either.

I know I can send messages with the raw data, but how could I convert any object TextChannel#send accepts into an object that the Disord API would accept? How does TextChannel#send do it?

@gabitojlsalj

how can I add multiple responses for each different slash command, it only replies the same 'hello world' to each slash command I add

@bobjoerules
Copy link

client.ws.on('INTERACTION_CREATE', async interaction => {
client.api.interactions(interaction.id, interaction.token).callback.post({data: {
type: 4,
data: {
content: 'test'
}
}})
})

when you do any / command it will send test how would I make it so I can have multiple / commands with different responses?

How can I edit a sent user message using the slash command, as it is done using the standard /me command?

PATCH /webhooks/<application_id>/<interaction_token>/messages/@original sending me error "Unknown Webhooks"

@SHUSTRIK-Milan you cannot send messages from the user or edit messages sent by the user; /me is a built-in client-side command, not an application command

It is a pity, that there are no such function 😢

Argument of type '"INTERACTION_CREATE"' is not assignable to parameter of type 'WSEventType'
Sadly this is a thing when using Typescript!

('INTERACTION_CREATE' as WSEventType)

Import WSEventType from discord.js

For me, typescript was complaining when using client.api . Here is how I respond to interaction (ephemeral) directly calling the webhook

await got.post(`https://discord.com/api/v8/interactions/${interaction.id}/${interaction.token}/callback`, {
      json: { type: 4, data: { content: '"hello world ...", flags: 64 } }
    })

Can you use the "Only visible to you" flag with a message embed?

you are able to do that in djs v13 using the emphermal thingy

client.api.applications(client.user.id).commands.get()

@advaith i did the

client.api.applications(client.user.id).commands.get()

and all i get is

Promise { <pending> }

but nothing turns up in the console, even my eval command nothing happens

hey @shamrockyt , you need to await the promise. You can do client.api.applications(client.user.id).commands.get().then(console.log) to send it to the console. If you're in an async function then you can do const cmds = await client.api.applications(...

@CRAFTIL yes you can do it now, just mark empheral as true
