THREAD_CREATE event Listener run method arguments

What I want to do:
I want to inspect the id of the parent channel where the thread was created.

The code I tried:

import { Listener } from '@sapphire/framework'
import type { ThreadChannel } from 'discord.js'

export class ForumListener extends Listener {
  public constructor(context: Listener.Context, options: Listener.Options) {
    super(context, {
      ...options,
      emitter: 'ws',
      event: 'THREAD_CREATE',
    })
  }

  public run(thread: ThreadChannel, newlyCreated: boolean) {
    const string = JSON.stringify(thread, null, 2)
    console.log(thread.parentId, newlyCreated)
    console.log(string)
  }
}

import { Listener } from '@sapphire/framework'
import type { ThreadChannel } from 'discord.js'

export class ForumListener extends Listener {
  public constructor(context: Listener.Context, options: Listener.Options) {
    super(context, {
      ...options,
      emitter: 'ws',
      event: 'THREAD_CREATE',
    })
  }

  public run(thread: ThreadChannel, newlyCreated: boolean) {
    const string = JSON.stringify(thread, null, 2)
    console.log(thread.parentId, newlyCreated)
    console.log(string)
  }
}

The result I got:

console.log(thread.parentId, newlyCreated) // undefined 0

console.log(thread.parentId, newlyCreated) // undefined 0

What am I missing?

Solution

Any event emitted by the discordjs websocket, such as THREAD_CREATE, doesn't receive a discordjs class, such as ThreadChannel, as first parameter. It receives the raw discord API data. If you type it as the type from discord-api-types (dunno which) you'll get the right properties in your code.

My guess is that it's an APIThreadChannel https://discord-api-types.dev/api/discord-api-types-v10/interface/APIThreadChannel

The

ws

ws

event also receives only ONE argument which is that

APIThreadChannel

APIThreadChannel

, there is no second argument

NewlyCreated

NewlyCreated

. That gets inserted by DiscordJS.

That said, you're far better off just rewriting it to the DiscordJS client event emitter:

import { Events, Listener } from '@sapphire/framework';
import type { ThreadChannel } from 'discord.js';

export class ForumListener extends Listener<typeof Events.ThreadCreate> {
  public constructor(context: Listener.Context, options: Listener.Options) {
    super(context, {
      ...options,
      event: Events.ThreadCreate
    });
  }

  public run(thread: ThreadChannel, newlyCreated: boolean) {
    console.log(thread.parentId, newlyCreated);
  }
}

import { Events, Listener } from '@sapphire/framework';
import type { ThreadChannel } from 'discord.js';

export class ForumListener extends Listener<typeof Events.ThreadCreate> {
  public constructor(context: Listener.Context, options: Listener.Options) {
    super(context, {
      ...options,
      event: Events.ThreadCreate
    });
  }

  public run(thread: ThreadChannel, newlyCreated: boolean) {
    console.log(thread.parentId, newlyCreated);
  }
}
