@RequireMemberPermission

About

The @RequireMemberPermission decorator is applied to a class implementing any CustomInteraction interface. It makes so that the execute method of the interaction is only run if the user triggering it has all permissions passed as argument in the guild scope.

It takes any number of PermissionResolvable as arguments:

...permissions: PermissionResolvable[] - The permissions to check for

It throws an error if applied to a class that does not have an 'execute' method.

Example

import { CustomChatInputCommand, ExtendedClient, RegisterChatInputCommand, RequireMemberPermission } from "@davipccunha/discordjs-helper";
import { ApplicationCommandType, ChatInputCommandInteraction, PermissionFlagsBits } from "discord.js";

@RegisterChatInputCommand("ping", "Ping the bot!")
@RequireMemberPermission(PermissionFlagsBits.Administrator)
export class PingCommand implements CustomChatInputCommand {
    name!: string;
    description!: string;
    type!: ApplicationCommandType.ChatInput;
    defaultPermission!: boolean;

    async execute(interaction: ChatInputCommandInteraction, client: ExtendedClient): Promise<void> {
        await interaction.reply('Pong!').catch(console.error);
    }
}

The execute method will only execute if the user who triggered the interaction has Administrator permissions in the guild scope. If this fails, a No Permission message is sent This message can be changed by using ErrorMessages.NoPermission = "New no permission message"
