CommandBuilder produces application command definitions matching Discord's API. Use it with the commands framework or hand the JSON to client.createCommand / client.bulkEditCommands.

A basic command

import { CommandBuilder } from 'athena';
 
const cmd = new CommandBuilder('avatar', "Show a user's avatar")
  .addUserOption({ name: 'user', description: 'Whose avatar', required: false });
 
await client.createCommand(cmd.toJSON());

A builder created as new CommandBuilder(name, description) serialises to a chat-input command without any extra call.

Options

new CommandBuilder('search', 'Search the docs')
  .addStringOption({ name: 'query', description: 'Text', required: true, autocomplete: true, min_length: 1, max_length: 100 })
  .addIntegerOption({ name: 'page', description: 'Page', min_value: 1, max_value: 100 })
  .addNumberOption({ name: 'amount', description: 'A decimal' })
  .addBooleanOption({ name: 'verbose', description: 'Extra detail' })
  .addUserOption({ name: 'user', description: 'A user' })
  .addChannelOption({ name: 'channel', description: 'A channel', channel_types: [ChannelType.GuildText] })
  .addRoleOption({ name: 'role', description: 'A role' })
  .addMentionOption({ name: 'target', description: 'User or role' })
  .addAttachmentOption({ name: 'file', description: 'Upload' });

String, integer, and number options accept up to 25 choices:

.addStringOption({ name: 'lang', description: 'Language', choices: [
  { name: 'English', value: 'en' },
  { name: 'Espanol', value: 'es' }
]})

Subcommands and groups

new CommandBuilder('settings', 'Server settings')
  .addSubcommand((s) => s.setName('view').setDescription('View settings'))
  .addSubcommandGroup((g) =>
    g.setName('notifications').setDescription('Manage notifications')
      .addSubcommand((s) => s.setName('enable').setDescription('Turn on'))
      .addSubcommand((s) => s.setName('disable').setDescription('Turn off'))
  );

Permissions and contexts

new CommandBuilder('purge', 'Bulk delete')
  .setMemberPermission(PermissionFlagsBits.ManageMessages)
  .setNSFW(false)
  .setContexts([InteractionContextType.Guild, InteractionContextType.BotDM])
  .setIntegrationTypes([ApplicationIntegrationType.GuildInstall, ApplicationIntegrationType.UserInstall]);
  • setMemberPermission(bits) sets the default required permission.
  • setContexts([...]) replaces the deprecated setDMPermission. Use Guild, BotDM, PrivateChannel.
  • setIntegrationTypes([...]) distinguishes guild installs from user installs.

Context menu commands

new CommandBuilder('Report message', '').setCommandType(ApplicationCommandType.Message);
new CommandBuilder('View profile', '').setCommandType(ApplicationCommandType.User);

No options, no description text. Since March 2026, Discord allows up to 15 USER and 15 MESSAGE context menu commands per app (up from 5 each).

Entry point commands

Apps with Activities get one entry point command (the command that launches the Activity from the App Launcher):

new CommandBuilder('launch', 'Launch the game').setHandler(EntryPointCommandHandlerType.AppHandler);

setHandler(handler) marks the command PRIMARY_ENTRY_POINT (type 4). Handler 1 (AppHandler): your app receives the interaction and responds, typically with interaction.launchActivity(). Handler 2 (DiscordLaunchActivity): Discord launches the Activity itself and your app receives nothing. Entry point commands are global-only and limited to 1 per app.

Localization

new CommandBuilder('ping', 'Replies with pong')
  .setNameLocalizations({ 'es-ES': 'ping' })
  .setDescriptionLocalizations({ 'es-ES': 'Responde pong' });

Autocomplete

Mark an option autocomplete: true and implement handleAutocomplete:

async handleAutocomplete(context, interaction) {
  const focused = interaction.focused();
  const matches = await search(focused.value as string);
  await interaction.acknowledge(matches.slice(0, 25).map((m) => ({ name: m.title, value: m.id })));
}

Deploying

await client.createCommand(builder.toJSON());                 // one global command
await client.bulkEditCommands([builder.toJSON()]);            // replace all global
await client.bulkEditGuildCommands(guildID, [builder.toJSON()]); // instant, per guild

With the framework, call deployCommands() once on ready and it picks guild or global scope from NODE_ENV and DEV_GUILD. See Commands framework.

Receiving a command without the framework

client.on('interactionCreate', async (interaction) => {
  if (!interaction.isCommand() || interaction.data.name !== 'avatar') return;
  const user = interaction.getUser('user') ?? interaction.user;
  await interaction.createMessage({ embeds: [{ title: user.username, image: { url: user.dynamicAvatarURL('png', 1024) } }] });
});
