Sub Commands

Creating a Sub Commands

In order to create Sub Commands you need to create a parent class command and then create the sub commands as classes that extends SubCommand and finally you need to add the sub commands to the parent command using the @Options decorator.

Note

Why we need to add the sub commands to the parent command using the @Options decorator?

Well, the answer in simple words is because discord treats sub commands as options of the parent command. And following that way in seyfert you pass the sub commands as options to the parent command.

Let’s check an example. Suppose you have the following directory structure:

• src
• Directorycommands

  • Directoryaccount

    • create.command.ts
    • delete.command.ts
    • parent.ts
• index.ts
• seyfert.config.js
• package.json
• tsconfig.json

parent.ts

Tip

With this file structure you can use @Autoload() and seyfert will add the commands for you so you don’t add them manually in the @Options decorator. But make sure you export by default the sub-commands.

import { Declare, Command, Options } from "seyfert";
import { CreateCommand } from "./create.command";
import { DeleteCommand } from "./delete.command";

@Declare({
  name: "account",
  description: "account command"
})
// Being in the same folder with @AutoLoad() you can save this
@Options([CreateCommand, DeleteCommand])
export class AccountCommand extends Command {}

create.command.ts

import { type CommandContext, Declare, SubCommand } from "seyfert";

@Declare({
  name: "create",
  description: "create a new something"
})
export class CreateCommand extends SubCommand {
  run(ctx: CommandContext) {
    // some logic there

    return ctx.write({
      content: "create command executed"
    });
  }
}

delete.command.ts

import { type CommandContext, Declare, SubCommand } from "seyfert";

@Declare({
  name: "delete",
  description: "delete something"
})
export class DeleteCommand extends SubCommand {
  run(ctx: CommandContext) {
    // some logic here

    return ctx.write({
      content: "delete command executed"
    });
  }
}
