@wolfstar/plugin-subcommands-advanced

Plugin for @wolfstar/http-framework that lets you split slash subcommands (and subcommand groups) into separate command classes, instead of putting every handler method on the parent.

Adapted from @kaname-png/plugin-subcommands-advanced for WolfStar’s HTTP interaction framework.

Installation

pnpm add @wolfstar/http-framework @wolfstar/plugin-subcommands-advanced

Usage

Import the register entrypoint before creating the client:

import "@wolfstar/plugin-subcommands-advanced/register";
import { Client, RegisterCommand } from "@wolfstar/http-framework";
import {
  Command,
  Subcommand,
  RegisterAsSubcommand,
  RegisterAsSubcommandGroup,
} from "@wolfstar/plugin-subcommands-advanced";

const client = new Client({
  subcommandsAdvanced: {
    // optional: piece names become parent/sub or parent/group/sub
    nameCommandsAutogenerated: true,
  },
});

Recommended layout:

commands/
└── utils/
    ├── parent.ts          // parent chat-input command
    ├── ping.ts            // subcommand
    └── poll/
        └── create.ts      // grouped subcommand

Parent command

import { RegisterCommand } from "@wolfstar/http-framework";
import { Subcommand } from "@wolfstar/plugin-subcommands-advanced";

@RegisterCommand((builder) =>
  builder
    .setName("utils")
    .setDescription("Utility commands")
    .addSubcommandGroup((group) => group.setName("poll").setDescription("Poll tools")),
)
export class UtilsCommand extends Subcommand {}

Direct subcommand

import { Command, RegisterAsSubcommand } from "@wolfstar/plugin-subcommands-advanced";

@RegisterAsSubcommand("utils", (builder) => builder.setName("ping").setDescription("Ping the bot"))
export class PingCommand extends Command {
  public override chatInputRun(interaction: Command.ChatInputInteraction) {
    return interaction.reply({ content: "Pong!" });
  }
}

Grouped subcommand

import { Command, RegisterAsSubcommandGroup } from "@wolfstar/plugin-subcommands-advanced";

@RegisterAsSubcommandGroup("utils", "poll", (builder) =>
  builder.setName("create").setDescription("Create a poll"),
)
export class PollCreateCommand extends Command {
  public override chatInputRun(interaction: Command.ChatInputInteraction) {
    return interaction.reply({ content: "Created!" });
  }
}

Constructor options (no decorators)

import { Command } from "@wolfstar/plugin-subcommands-advanced";

export class PingCommand extends Command {
  public constructor(context: Command.LoaderContext, options: Command.Options) {
    super(context, {
      ...options,
      registerSubCommand: {
        parentCommandName: "utils",
        slashSubcommand: (builder) => builder.setName("ping").setDescription("Ping!"),
      },
    });
  }

  public override chatInputRun(interaction: Command.ChatInputInteraction) {
    return interaction.reply({ content: "Pong!" });
  }
}

How it works

@wolfstar/http-framework routes subcommands to methods on the parent command instance. This plugin:

1. Lets child command classes register themselves into in-memory registries (by parent name).
2. After all command pieces are constructed, rebuilds the parent’s chat-input resolver and CommandRouter, installing thin delegate methods that call each child’s chatInputRun.

You do not need to call the optional hooks.subcommands / hooks.groups helpers unless you are registering the parent imperatively and want to attach builders yourself.

Notes

• HTTP-only: there is no message-command support (unlike the Sapphire original).
• Child classes should not use @RegisterCommand — only the parent registers the top-level slash command.
• Subcommand groups must still be declared on the parent (via @RegisterCommand builder or registerApplicationCommands).
