🖲️ Commands

A command starts with a prefix (by default: +) or with / (for slash commands).

We are going to create a simple command that will give information about itself. The first thing to do it's create a file inside ./sources/modules/<module_name>/commands (replace <module_name> with the name of your module). In this example, we can call the command itself so let's create ./sources/modules/<module_name>/commands/itself.js and paste this code :

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

async function parse(interaction, cmd, args)
{
	if (interaction.options)
	{
		// Slash command (/itselt)
		await interaction.reply(
			"🖲️ **Command type:**\n- slash command\n"+
			`📇 **Command Name:**\n- ${cmd}\n`+
			`🔢 **Number of arguments:**\n- ${args.length}\n`+
			`✍️ **Requested by:**\n- ${interaction.member.user.username}\n`
		);
	}
	else
	{
		// Classic command (+itselt)
		await interaction.channel.send(
			"🖲️ **Command type:**\n- classic command"+
			`📇 **Command Name:**\n- ${cmd}\n`+
			`🔢 **Number of arguments:**\n- ${args.length}\n`+
			`✍️ **Requested by:**\n- ${interaction.member.user.username}\n`
		);
	}
}

module.exports = {
	parse,
	name: "itself",
	permissions: [],
	builder: new SlashCommandBuilder()
		.setName("itself")
		.setDescription("I give informations about myselft."),
	any_guild: false,
	dm: false
}

The method parse is run by system when a message is sent and starts with bot's prefix (+ by default) or when a slash command is executed.

async function parse(interaction, cmd, args)

As you can see we have tree arguments:

• interaction → corresponding to the event (MessageCreate, or InteractionCommand)
• cmd → name of the command
• args → corresponds to all the elements that follow the command name in a classic command

⎯ e.g of args

+itself arg1 arg2

⎯ Exports

At the bottom of the file we have exports, which includes several important elements.

module.exports = {
	parse,
	name: "itself",
	permissions: [],
	builder: new SlashCommandBuilder()
		.setName("itself")
		.setDescription("I give informations about myselft."),
	any_guild: false,
	dm: false
}

• parse → method to handle the command
• name → name of the command
• permissions → list of methods to check ifinteraction.member has the right permissions
• builder → a SlashCommandBuilder
• any_guild → if false, the command can be executed only on the main guild
• dm → if true, we can use this command in direct messages
