🎻 Introduction

This module is an extension of discord.js, so the internal behavior (methods, properties, ...) is the same.

This library allows you to use TypeScript decorators on discord.js, it simplify your code and improve the readability !

📟 @Slash - Discord commands

Discord has it's own command system now, you can simply declare commands and use Slash commands this way

import { Discord, Slash } from "@typeit/discord";
import { CommandInteraction } from "discord.js";

@Discord()
abstract class AppDiscord {
  @Slash("hello")
  private hello(
    @Option("text")
    text: string,
    interaction: CommandInteraction
  ) {
    // ...
  }
}

Decorators related to Slash commands

There is a whole system that allows you to implement complex Slash commands

• @Choice
• @Choices
• @Option
• @Permission
• @Guild
• @Group
• @Description
• @Guard

💡@On / @Once - Discord events

We can declare methods that will be executed whenever a Discord event is triggered.

Our methods must be decorated with the @On(event: string) or @Once(event: string) decorator.

That's simple, when the event is triggered, the method is called:

import { Discord, On, Once } from "@typeit/discord";

@Discord()
abstract class AppDiscord {
  @On("message")
  private onMessage() {
    // ...
  }

  @Once("messageDelete")
  private onMessageDelete() {
    // ...
  }
}

⚔️ Guards

We implemented a guard system thats work pretty like the Koa middleware system

You can use functions that are executed before your event to determine if it's executed. For example, if you want to apply a prefix to the messages, you can simply use the @Guard decorator.

The order of execution of the guards is done according to their position in the list, so they will be executed in order (from top to bottom).

Guards can be set for @Slash, @On, @Once, @Discord and globaly.

import { Discord, On, Client, Guard } from "@typeit/discord";
import { NotBot } from "./NotBot";
import { Prefix } from "./Prefix";

@Discord()
abstract class AppDiscord {
  @On("message")
  @Guard(
    NotBot, // You can use multiple guard functions, they are excuted in the same order!
    Prefix("!")
  )
  async onMessage([message]: ArgsOf<"message">) {
    switch (message.content.toLowerCase()) {
      case "hello":
        message.reply("Hello!");
        break;
      default:
        message.reply("Command not found");
        break;
    }
  }
}
