discordts-decorators

A discordjs package that uses TC39 decorator pattern. This package is a wrapper for discord.js that allows you to use decorators to create commands and events.

Examples

Command

import { Injections } from "discordts-decorators";
import { CommandInteraction } from "discord.js";

const { Discord, Command, Autocomplete } = Injections();

@Discord
export class Fun {
  // Read the documention for more information
  // on how to use integration_types and context
  // https://discord.com/developers/docs/interactions/application-commands#interaction-contexts
  public static integration_types = [0, 1];
  public static context = [0, 1, 2];

  @Command('Ping the bot')
  public static async ping(interaction: CommandInteraction) {
    const { createdTimestamp } = interaction;
    const reply = await interaction.editReply('Pinging...');
    const messagePing = reply.createdTimestamp - createdTimestamp;
    const websocketPing = interaction.client.ws.ping;

    await interaction.editReply(`Pong!\n**Message Ping:** ${messagePing}ms\n**Websocket Ping:** ${websocketPing}ms`);
  }

  @Command('Autocomplete test', 10, true)
  @Autocomplete('test', 'Test autocomplete', true)
  public static async autocompletetest(interaction: CommandInteraction | AutocompleteInteraction) {
    if (interaction.isAutocomplete()) {
      // @ts-ignore
      await interaction.respond([
        {
          name: 'Test 1',
          value: 'test1'
        },
        {
          name: 'Test 2',
          value: 'test2'
        }
      ]);
    }
  }
}

Event

import {
  Collection,
  CommandInteraction,
  CommandInteractionOptionResolver,
  InteractionDeferReplyOptions
} from 'discord.js';
import { Injections } from 'discordts-decorators';

const { Discord, Event } = Injections();

@Discord
export class EventManager {
  @Event()
  public static async ready() {
    console.log('Client is ready!');
  }

  @Event()
  public static async error(error: Error) {
    console.error(error);
  }

  @Event()
  public static async interactionCreate(interaction: CommandInteraction) {
    const { client } = interaction;
    const subcommmand = (interaction.options as CommandInteractionOptionResolver).getSubcommand();
    const commandName = interaction.commandName;

    console.log(`Command: ${commandName} | Subcommand: ${subcommmand}`);

    // console.log(client.commands)
    const subcommands = client.commands.get(commandName).options;
    const command = subcommands.find((cmd) => cmd.name === subcommmand);
    if (!command) return;

    if (interaction.isAutocomplete()) {
      try {
        await command.autocomplete(interaction);
      } catch (error) {
        console.error(error);
      }

      return;
    }

    // Cooldowns handling
    const cooldowns = client.cooldowns;
    if (!cooldowns.has(command.name)) {
      cooldowns.set(command.name, new Collection<string, string>());
    }

    const now = new Date().getTime();
    const timestamps = cooldowns.get(command.name);
    const cooldownAmount = command.cooldown * 1000;
    if (timestamps.has(interaction.user.id)) {
      const expirationTime = timestamps.get(interaction.user.id) + cooldownAmount;
      if (now < expirationTime) {
        const timeLeft = Math.round((expirationTime - now) / 1000);
        return interaction.reply({
          content: `Please wait ${timeLeft.toFixed(1)} more second(s) before reusing the \`${command.name}\` command.`,
          ephemeral: true
        });
      }
    }

    timestamps.set(interaction.user.id, now);
    setTimeout(() => timestamps.delete(interaction.user.id), cooldownAmount);
    // End of cooldowns handling

    // Command execution
    if (interaction.isCommand()) {
      try {
        await interaction.deferReply({ ephemeral: command.ephemeral || false } as InteractionDeferReplyOptions);
        setTimeout(() => {
          if (!interaction.replied) {
            interaction.editReply('This interaction has expired.');
            return;
          }
        }, 10000);
        await command.run(interaction);
      } catch (error) {
        console.error(error);
        await interaction.editReply('There was an error while executing this command!');
      }
    }
  }
}

export default EventManager;

Bot Initialization

import {IntentsBitField} from "discord.js";
import { BotManager } from "discordts-decorators";
import EventManager from "./events/EventManager.js";
import Commands from "./commands/index.js";

const intents = new IntentsBitField([
  'Guilds',
  'GuildMembers',
  'GuildMessages',
  'GuildMessageReactions',
  'GuildModeration',
  'GuildPresences',
  'GuildInvites',
  'DirectMessages',
  'DirectMessageReactions',
  'MessageContent',
]);

const DiscordBot = BotManager.getInstance();

DiscordBot.setPrivateData({
  id: 'bot id',
  token: 'bot token',
  intents,
  name: 'VeryCoolName',
}).create(EventManager);

for (const command of Commands) {
  DiscordBot.create(command);
}

await DiscordBot.buildClient();
await DiscordBot.login();
DiscordBot.setPresence('idle', {
  name: 'with discordts-decorators',
});
