📖 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 simplifies your code and improves the readability!

This repository is a fork of OwenCalvin/discord.ts by @OwenCalvin, which is no longer actively maintained.

With discordx, we intend to provide latest upto date package to build bots with many features, such as multi-bot, simple commands, pagination etc. Updated daily with discord.js changes.

If you have any issues or feature requests, Please open an issue at Github or join discord server

🆕 New features

• Support for multiple bots in a single nodejs instance (@Bot)
• @SimpleCommand to use old fashioned command, such as !hello world
• @SimpleCommandOption Parse and define command options like @SlashOption
• New interactions/decorators: @ButtonComponent @SelectMenuComponent @ContextMenu
• New method client.initApplicationCommands to create/update/remove discord application commands (slash/context menu) for global and defined guilds
• Lint improved internal source code for better type support
• Provided more examples for new decorators
• Support TSyringe

🧮 Packages

Here are more packages from us to extend the functionality of your Discord bot.

📔 Decorators

There is a whole system that allows you to implement complex slash/simple commands and handle interactions like button, select menu, contextmenu etc.

General

• @Discord
• @Guard
• @Guild
• @Bot
• @Permission
• @On
• @Once

Commands

• @Slash
• @SlashChoice
• @SlashGroup
• @SlashOption
• @SimpleCommand
• @SimpleCommandOption

GUI Interactions

• @ButtonComponent
• @SelectMenuComponent
• @ContextMenu

📟 @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 "discordx";
import { CommandInteraction } from "discord.js";

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

📟 @ButtonComponent - Discord button component interaction handler

add button interaction handler for your bot using @ButtonComponent decorator

@Discord()
class buttonExample {
  @Slash("hello")
  hello(interaction: CommandInteraction) {
    const helloBtn = new MessageButton()
      .setLabel("Hello")
      .setEmoji("👋")
      .setStyle("PRIMARY")
      .setCustomId("hello-btn");

    const row = new MessageActionRow().addComponents(helloBtn);

    interaction.reply({
      content: "Say hello to bot",
      components: [row],
    });
  }

  @ButtonComponent("hello-btn")
  mybtn(interaction: ButtonInteraction) {
    interaction.reply(`👋 ${interaction.member}`);
  }
}

📟 @SelectMenuComponent - Discord menu component interaction handler

add menu interaction handler for your bot using @SelectMenuComponent decorator

const roles = [
  { label: "Principal", value: "principal" },
  { label: "Teacher", value: "teacher" },
  { label: "Student", value: "student" },
];

@Discord()
class buttons {
  @SelectMenuComponent("role-menu")
  async handle(interaction: SelectMenuInteraction) {
    await interaction.deferReply();

    // extract selected value by member
    const roleValue = interaction.values?.[0];

    // if value not found
    if (!roleValue)
      return await interaction.followUp("invalid role id, select again");
    await interaction.followUp(
      `you have selected role: ${
        roles.find((r) => r.value === roleValue).label
      }`
    );
    return;
  }

  @Slash("roles", { description: "role selector menu" })
  async myroles(interaction: CommandInteraction): Promise<unknown> {
    await interaction.deferReply();

    // create menu for roels
    const menu = new MessageSelectMenu()
      .addOptions(roles)
      .setCustomId("role-menu");

    // create a row for meessage actions
    const buttonRow = new MessageActionRow().addComponents(menu);

    // send it
    interaction.editReply({
      content: "select your role!",
      components: [buttonRow],
    });
    return;
  }
}

📟 @ContextMenu - create discord context menu options with ease!

add discord context menu for your bot using @ContextMenu decorator

@Discord()
class contextTest {
  @ContextMenu("MESSAGE", "message context")
  messageHandler(interaction: ContextMenuInteraction) {
    console.log("I am message");
  }

  @ContextMenu("USER", "user context")
  userHandler(interaction: ContextMenuInteraction) {
    console.log("I am user");
  }
}

📟 @SimpleCommand - Command Processor

Create a simple command handler for messages using @SimpleCommand. Example !hello world

@Discord()
class commandTest {
  @SimpleCommand("permcheck", { aliases: ["ptest"] })
  @Permission(false)
  @Permission({
    id: "462341082919731200",
    type: "USER",
    permission: true,
  })
  permFunc(command: SimpleCommandMessage) {
    command.message.reply("access granted");
  }
}

💡@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 "discordx";

@Discord()
abstract class AppDiscord {
  @On("messageCreate")
  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 globally.

import { Discord, On, Client, Guard } from "discordx";
import { NotBot } from "./NotBot";
import { Prefix } from "./Prefix";

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