Autocomplete support example

togglecommand.js

// This is written in JS but the handler will still have TS support as expected

const {
  PermissionFlagsBits,
  ApplicationCommandOptionType,
} = require('discord.js')

module.exports = {
  description: 'Toggles a command on or off for your guild',

  type: 'SLASH',
  guildOnly: true,
  testOnly: true,

  permissions: [PermissionFlagsBits.Administrator],

  options: [
    {
      name: 'command',
      description: 'The command to toggle on or off',
      type: ApplicationCommandOptionType.String,
      required: true,
      autocomplete: true,
    },
  ],

  autocomplete: (interaction, command, arg) => {
    // Return all of the registered commands
    return [...command.instance.commandHandler.commands.keys()]
  },

  callback: async ({ instance, guild, text: commandName, interaction }) => {
    // TODO: Toggle the command
  },
}
