export default undefined;

declare module "@sapphire/framework" {

moderator.ts

  }

    return member?.roles.cache.has(config.StaffRoleID)
      ? this.ok()
      : this.error({ message: "Only moderators can use this command!" });
  }
}

OnlyMods is not moderator

fenishOP•2y ago

oh should i use file name for that ?

Favna•2y ago

and make it not index.d.ts but just put it just in index.ts well the file name dictates the precondition name at runtime so if you dont match those, TS may accept it but it wont work in runtime

fenishOP•2y ago

ahh isee but it doesn't throw error it works but ah wait yea members can't see message is there something to do like error handling

Favna•2y ago

We have a guide page dedicated to handling precondition denials

oh oaky

import {
  Listener,
  type ChatInputCommandDeniedPayload,
  Events,
  UserError,
} from "@sapphire/framework";

export class ChatInputCommandDenied extends Listener<
  typeof Events.ChatInputCommandDenied
> {
  public run(error: UserError, { interaction }: ChatInputCommandDeniedPayload) {
    if (Reflect.get(Object(error.context), "silent")) return;

    if (interaction.deferred || interaction.replied) {
      return interaction.editReply({
        content: error.message,
      });
    }

    return interaction.reply({
      content: error.message,
      ephemeral: true,
    });
  }
}

import {
  Listener,
  type ChatInputCommandDeniedPayload,
  Events,
  UserError,
} from "@sapphire/framework";

export class ChatInputCommandDenied extends Listener<
  typeof Events.ChatInputCommandDenied
> {
  public run(error: UserError, { interaction }: ChatInputCommandDeniedPayload) {
    if (Reflect.get(Object(error.context), "silent")) return;

    if (interaction.deferred || interaction.replied) {
      return interaction.editReply({
        content: error.message,
      });
    }

    return interaction.reply({
      content: error.message,
      ephemeral: true,
    });
  }
}

i put this inside of "listeners" folder it doesn't send my error message is it because of my chatinput command or something like this or file structure, etc.

name of the file? if it's chatInputCommandDenied.ts (case sensitive!!) then it should be fine

fenishOP•2y ago

should i name my files with name of classes? or is this special for this one and are there any guide for file naming or directory structure for this kind of files

Favna•2y ago

the name is always the name of the piece (unless set otherwise) and in the case of listeners the name of the piece is also the name of the event to bind it on (unless set otherwise) for events there is the events enum which is on the sapphire docs
