Delete All Commands Function

[ming-suhi]

While da-slash does provide a delete function, it's only setup for commands it created and that still exists.
So if I delete a command's file, I can no longer call it up and delete it, I'd have to recreate the command with the same name, then delete it.

Here's a deleteCommands function that could be added to client.js, allowing you to delete all commands initialized by the bot, either globally or per guild via await slash.deleteCommands(guild_ids, del_global).
guild_ids being an array of guild ids.
del_global being a boolean to delete global commands or not.

Function

async deleteCommands(guild_ids = false, del_global = false) {
  let deletedCommands = new Array();
  if (guild_ids) {
    let postedGuildCommands = new Array();
    for (let guild_id of guild_ids) {
      const guildCommands = await this.client.api.applications(this.client.user.id).guilds(guild_id).commands.get();
      for (let i = 0; i < guildCommands.length; i++) {
        this.client.api.applications(this.client.user.id).guilds(guild_id).commands(guildCommands[i].id).delete();
      }
      postedGuildCommands.push({ guild: guild_id, commands: guildCommands });
    }
    deletedCommands.push({ guilds: postedGuildCommands });
  }
  if (del_global) {
    const postedGlobalCommands = await this.client.api.applications(this.client.user.id).commands.get();
    for (let i = 0; i < postedGlobalCommands.length; i++) {
      this.client.api.applications(this.client.user.id).commands(postedGlobalCommands[i].id).delete();
    }
    deletedCommands.push({ global: postedGlobalCommands });
  }
  return deletedCommands;
}

Usage

client.on('ready', async () => {
  await slash.deleteCommands(['613425648685547541','197038439483310086'], true);
  slash.postCommands();
});
