Task 1: Creating a Basic /ping Command

We can start by making a command that replies with "Pong!" when the user types /ping.

Code

const { SlashCommandBuilder } = require('discord.js');

module.exports = {
  data: new SlashCommandBuilder()
    .setName('ping')
    .setDescription('Replies with Pong!'),
  async execute(interaction) {
    await interaction.reply('Pong!');
  },
};

Explanation

• SlashCommandBuilder is used to define your slash command (/ping).
• The module.exports object contains:
  • data: Defines the command name and description.
  • execute: The function called when the command runs.

Task 2: Formatting Bot Messages

Discord.js provides built-in formatting tools to stylize your bot’s messages.

Example

const { blockQuote, bold, italic, quote, spoiler, strikethrough, underline, subtext } = require('discord.js');
const string = 'Hello!';

const boldString = bold(string);
const italicString = italic(string);
const strikethroughString = strikethrough(string);
const underlineString = underline(string);
const spoilerString = spoiler(string);
const quoteString = quote(string);
const blockquoteString = blockQuote(string);
const subtextString = subtext(string);

Combine Styles

You can nest formatting functions for more expressive messages:

const message = bold(italic("This is bold and italic!"));
await interaction.reply(message);

Emphasizing Bot Responses

Use formatting to emphasize context:

await interaction.reply(blockQuote(bold("System Message: ") + "Command executed successfully."));

Or for dramatic or humorous effect:

await interaction.reply(spoiler("Secret message inside..."));

Usage in Commands

To make the reply bold in your /ping command:

await interaction.reply(bold('Pong!'));

You can also:

• Italicize with italic('Pong!')
• Make it a spoiler with spoiler('Pong!')
• Use other formatting methods above

Task 3: Pinging a User

Now we will update the /ping command to mention a specific user.

Updated Command

const { SlashCommandBuilder } = require('discord.js');

module.exports = {
  data: new SlashCommandBuilder()
    .setName('ping')
    .setDescription('Ping a user!')
    .addUserOption(option =>
      option.setName('target')
        .setDescription('User to ping')
        .setRequired(true)
    ),
  async execute(interaction) {
    const user = interaction.options.getUser('target');
    await interaction.reply(`Pong! ${user}`);
  },
};

Explanation

• addUserOption: Adds a required user input to the command.

• interaction.options.getUser('target'): Retrieves the user selected.

• ${user}: Automatically converts to @mention.

• You’ve created a basic /ping command.

• You learned how to stylize bot messages using Discord.js utilities.

• You enhanced the command to ping specific users.
