Discord Bot with Slash Commands and Modals

This project is a fully-featured Discord bot written in Node.js, using the discord.js library. It includes functionalities like handling slash commands, context menu commands, and displaying modals for user input.

Features

• Slash Commands: Commands that can be triggered using / in Discord, like /ping to check bot latency.
• Modals: Interactive modals where users can input data, for example, /modal-example.
• Context Menu Commands: Right-click context menu commands for users or messages.
• Ephemeral Replies: Ability to send private, ephemeral replies to users.
• Dynamic Command Registration: Automatically registers commands based on the project directory structure.
• User Installed App Support: Automatically registers commands global to Discord via User Apps

Installation

Prerequisites

Ensure you have the following installed:

• Node.js (v16.6.0 or higher)
• Discord.js (v14.x)
• A Discord Bot Token (see here for instructions)

Clone the Repository

git clone https://git.ssh.surf/snxraven/DiscordJS-v14-Template.git
cd DiscordJS-v14-Template

Install Dependencies

npm install

Environment Variables

Create a .env file in the root of your project directory with the following content:

TOKEN=YOUR_DISCORD_BOT_TOKEN
DISCORD_CLIENT_ID=APPIDHERE

Replace YOUR_DISCORD_BOT_TOKEN with your actual bot token from the Discord Developer Portal.

File Structure

• index.js: The entry point of the bot that initializes the client and loads commands and events.
• handler/index.js: Dynamically loads commands and events and registers slash commands with Discord.
• events/: Folder containing event listeners such as ready.js (bot ready event) and interactionCreate.js (command handling).
• commands/: Folder containing command files. Commands are organized into subfolders based on category.
  • commands/info/: Contains commands like /ping and /modal-example.
  • commands/context/: Contains context menu commands like ping-test.

Commands

• ping: Returns the bot's websocket latency with an ephemeral reply.
• modal-example: Displays a modal for user input.
• ping-test: A context menu command that returns latency when right-clicking a message.

Running the Bot

To start the bot, run:

node index.js

If everything is set up correctly, you should see the following message:

YourBotName is up and ready to go!

The bot will automatically register slash commands for every guild it's in.

Command Examples

Slash Command: /ping

Returns the bot's websocket latency in an embed message.

Slash Command: /modal-example

Opens a modal where users can input text, which is then displayed back to them.

Context Menu Command: ping-test

Available by right-clicking a message and choosing this context command. It shows the bot's latency.

Adding New Commands

To add a new command:

1. Create a new .js file in the commands/ folder under the appropriate subfolder.
2. Define your command with the structure used in the existing commands.
3. Restart the bot to automatically load the new command.

Example command structure:

module.exports = {
  name: "new-command",
  description: "Describe your command here",
  run: async (client, interaction) => {
    // Command logic
  },
};

Modals

The bot supports modals for user input. To add a new modal, create a new command in the commands/ folder and use the ModalBuilder from discord.js to display a modal.

Example modal code:

const { ModalBuilder, TextInputBuilder, TextInputStyle } = require('discord.js');
const { ActionRowBuilder } = require('discord.js');

module.exports = {
    name: "modal-example",
    description: "Show a demo modal!",
    run: async (client, interaction) => {
        const modal = new ModalBuilder()
            .setCustomId('example-modal')
            .setTitle('Example Modal');
        
        const input = new TextInputBuilder()
            .setCustomId('input-field')
            .setLabel("Your Input")
            .setStyle(TextInputStyle.Paragraph);

        const row = new ActionRowBuilder().addComponents(input);
        modal.addComponents(row);

        await interaction.showModal(modal);
    }
};

Handling Ephemeral Replies

Commands can return ephemeral (private) responses, making replies visible only to the command invoker. To enable ephemeral replies, add a private property to the command definition:

module.exports = {
  name: "ping",
  description: "Returns latency",
  private: true, // This makes the reply private
  run: async (client, interaction) => {
    // Command logic here
  },
};

Events

The bot listens for two primary events:

• ready: Triggered when the bot is logged in and ready.
• interactionCreate: Triggered when a user interacts with the bot through slash commands, modals, or context menu commands.

Troubleshooting

• Ensure you have the correct bot token in your .env file.
• Make sure your bot has the necessary permissions to register commands in the guilds it's in.
• If commands aren’t registering, try manually clearing the commands in the Discord Developer Portal or use guild-specific commands to speed up testing.
