Create Discord Command

Create Discord Command

Create one command module that exports command and matches the repository type pattern.

Workflow

1. Confirm requested command shape.

• Determine command name, description, options/subcommands, and response style (ephemeral/public).

2. Choose command file location.

• Use src/commands/<name>.ts for a simple command.
• Use src/commands/<group>/index.ts for grouped or complex command sets.
• For complex implementations, prefer barrel-file organization by default: create a dedicated subdirectory and place the command in index.ts.

3. Implement typed command module.

• Import command types from discord.js and Command from @/types.
• Export command exactly.
• Use SlashCommandBuilder for schema and execute for behavior.

4. Handle runtime behavior safely.

• Use MessageFlags.Ephemeral when response should be private.
• Call interaction.deferReply() before long operations.
• Wrap non-trivial logic with clear error paths if needed.

5. Validate and deploy.

• Run npm run typecheck.
• Run npm run check.
• Run npm run deploy-commands (or npm run deploy-commands -- --global when explicitly requested).

Command Template

import { type ChatInputCommandInteraction, MessageFlags, SlashCommandBuilder } from 'discord.js';
import type { Command } from '@/types';

export const command: Command<ChatInputCommandInteraction> = {
  data: new SlashCommandBuilder().setName('command-name').setDescription('Command description'),
  execute: async (interaction) => {
    await interaction.reply({
      content: 'Response',
      flags: MessageFlags.Ephemeral
    });
  }
};

Constraints

• Use @/ path aliases, not relative imports for internal modules.
• Keep strict typing; avoid non-null assertions unless required.
• Keep behavior aligned with src/events/interaction-create.ts command routing.
