# Component interactions

Every button click or select menu selection on a component sent by your bot fires an interaction, triggering the Client#event:interactionCreateopen in new window event. How you decide to handle this will likely depend on the purpose of the components. Options include:

• Waiting for a single interaction via InteractionResponse#awaitMessageComponent()open in new window.
• Listening for multiple interactions over a period of time using an InteractionCollectoropen in new window.
• Creating a permanent component handler in the Client#event:interactionCreateopen in new window event.

# Responding to component interactions

As with all other interactions message components interactions require a response within 3 seconds, else Discord will treat them as failed.

Like slash commands, all types of message component interactions support the reply(), deferReply(), editReply() and followUp() methods, with the option for these responses to be ephemeral. These function identically to how they do for slash commands, so refer to the page on slash command response methods for information on those.

Component interactions also support two additional methods of response, detailed below and demonstrated in examples later on the page.

# Updates

Responding to a component interaction via the update() method acknowledges the interaction by editing the message on which the component was attached. This method should be preferred to calling editReply() on the original interaction which sent the components. Like editReply(), update() cannot be used to change the ephemeral state of a message.

Once update() has been called, future messages can be sent by calling followUp() or edits can be made by calling editReply() on the component interaction.

# Deferred updates

Responding to a component interaction via the deferUpdate() method acknowledges the interaction and resets the message state. This method can be used to suppress the need for further responses, however it's encouraged to provide meaningful feedback to users via an update() or ephemeral reply() at least.

Once deferUpdate() has been called, future messages can be sent by calling followUp() or edits can be made by calling editReply() on the component interaction.

# Awaiting components

If you followed our buttons guide, the confirmation workflow for the ban command is a good example of a situation where your bot is expecting to receive a single response, from either the Confirm or Cancel button.

Begin by storing the InteractionResponseopen in new window as a variable, and calling InteractionResponse#awaitMessageComponent()open in new window on this instance. This method returns a Promise that resolves when any interaction passes its filter (if one is provided), or throws if none are received before the timeout. If this happens, remove the components and notify the user.

const response = await interaction.reply({
	content: `Are you sure you want to ban ${target.username} for reason: ${reason}?`,
	components: [row],
});

const collectorFilter = i => i.user.id === interaction.user.id;

try {
	const confirmation = await response.awaitMessageComponent({ filter: collectorFilter, time: 60_000 });
} catch (e) {
	await interaction.editReply({ content: 'Confirmation not received within 1 minute, cancelling', components: [] });
}

With the confirmation collected, check which button was clicked and perform the appropriate action.

const response = await interaction.reply({
	content: `Are you sure you want to ban ${target.username} for reason: ${reason}?`,
	components: [row],
});

const collectorFilter = i => i.user.id === interaction.user.id;
try {
	const confirmation = await response.awaitMessageComponent({ filter: collectorFilter, time: 60_000 });

	if (confirmation.customId === 'confirm') {
		await interaction.guild.members.ban(target);
		await confirmation.update({ content: `${target.username} has been banned for reason: ${reason}`, components: [] });
	} else if (confirmation.customId === 'cancel') {
		await confirmation.update({ content: 'Action cancelled', components: [] });
	}
} catch (e) {
	await interaction.editReply({ content: 'Confirmation not received within 1 minute, cancelling', components: [] });
}

# Component collectors

For situations where you want to collect multiple interactions, the Collector approach is better suited than awaiting singular interactions. Following on from the select menus guide, you're going to extend that example to use an InteractionCollectoropen in new window to listen for multiple StringSelectMenuInteractionopen in new windows.

Begin by storing the InteractionResponseopen in new window as a variable, and calling InteractionResponse#createMessageComponentCollector()open in new window on this instance. This method returns an InteractionCollector that will fire its InteractionCollector#event:collectopen in new window event whenever an interaction passes its filter (if one is provided).

In the collect event, each interaction is a StringSelectMenuInteractionopen in new window thanks to the componentType: ComponentType.StringSelect option provided to the collector (and because that was the only type of component in the message). The selected value(s) are available via the StringSelectMenuInteraction#valuesopen in new window property.

const response = await interaction.reply({
	content: 'Choose your starter!',
	components: [row],
});

const collector = response.createMessageComponentCollector({ componentType: ComponentType.StringSelect, time: 3_600_000 });

collector.on('collect', async i => {
	const selection = i.values[0];
	await i.reply(`${i.user} has selected ${selection}!`);
});

# The Client#interactionCreate event

Third and finally, you may wish to have a listener setup to respond to permanent button or select menu features of your guild. For this, returning to the Client#event:interactionCreateopen in new window event is the best approach.

If your event handling has been setup in multiple files as per our event handling guide, you should already have an events/interactionCreate.js file that looks something like this.

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

module.exports = {
	name: Events.InteractionCreate,
	async execute(interaction) {
		if (!interaction.isChatInputCommand()) return;

		const command = interaction.client.commands.get(interaction.commandName);

		if (!command) {
			console.error(`No command matching ${interaction.commandName} was found.`);
			return;
		}

		try {
			await command.execute(interaction);
		} catch (error) {
			console.error(`Error executing ${interaction.commandName}`);
			console.error(error);
		}
	},
};

The way this was previously set up returns from the execute function whenever it encounters an interaction that is not a ChatInputCommandInteraction, as shown on the highlighted line above. The first change that needs to be made is to invert this logic, without actually changing the functionality.

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

module.exports = {
	name: Events.InteractionCreate,
	async execute(interaction) {
		if (interaction.isChatInputCommand()) {
			const command = interaction.client.commands.get(interaction.commandName);

			if (!command) {
				console.error(`No command matching ${interaction.commandName} was found.`);
				return;
			}

			try {
				await command.execute(interaction);
			} catch (error) {
				console.error(`Error executing ${interaction.commandName}`);
				console.error(error);
			}
		}
	},
};

Now that the logic is setup to run code when something is a ChatInputCommandInteraction, rather than to stop and exit when it isn't, you can add handling for additional interaction types via simple if...else logic.

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

module.exports = {
	name: Events.InteractionCreate,
	async execute(interaction) {
		if (interaction.isChatInputCommand()) {
			const command = interaction.client.commands.get(interaction.commandName);

			if (!command) {
				console.error(`No command matching ${interaction.commandName} was found.`);
				return;
			}

			try {
				await command.execute(interaction);
			} catch (error) {
				console.error(`Error executing ${interaction.commandName}`);
				console.error(error);
			}
		} else if (interaction.isButton()) {
			// respond to the button
		} else if (interaction.isStringSelectMenu()) {
			// respond to the select menu
		}
	},
};
