Retrieving the Channel of the Message

Sometimes it's useful to retrieve the channel in which the message was sent.

For demonstrating how you can retrieve the channel from a Discord.js command we will code the ClearChannelCommand that will delete messages from the channel the message was sent.

Writing the `ClearChannelCommand`#

path/to/your/app/src/Commands/ClearChannelCommand.ts

import { BaseCommand, Channel, ChannelContract, Command } from "discapp";

@Command()
export class ClearChannelCommand extends BaseCommand {
  @Channel()
  public channel: ChannelContract;

  public async execute() {
    const allMessages = await this.channel.messages.fetch({
      limit: 100,
    });
    let deletedMessages = 0;

    await Promise.all(
      allMessages.map(async (message) => {
        if (message.deletable) {
          ++deletedMessages;
          await message.delete();
        }
      })
    );

    return `Finished cleaning all the messages (${deletedMessages})`;
  }
}

The ClearChannelCommand will try to delete all the latest 100 message (in parallel).

Testing the `ClearChannelCommand`#

You can test the command by sending:

!clear-channel

This should delete by arround 100 messages from the channel you send this command.
