Updating to v15

Version 15 is in a pre-release state, but should be usable!
That being said, we do not recommend you update your production instance without careful and thorough testing!
Please report any bugs you experience at our GitHub repository:

https://github.com/discordjs/discord.js/issues

Before you start

Make sure you're using the latest LTS version of Node. To check your Node version, use node --version in your terminal or command prompt, and if it's not high enough, update it! There are many resources online to help you with this step based on your host system.

Breaking Changes

ActionRow

ActionRow.from() has been removed. Use ActionRowBuilder.from() instead.

ApplicationCommand

ApplicationCommand#dmPermission and ApplicationCommand#setDMPermission() have been removed. This was legacy functionality for commands—use contexts instead.

ApplicationCommandManager

ApplicationCommandManager#fetch() method has been updated for consistency with other managers. Previously, it accepted two parameters: id (a snowflake or an options object) and an options object. Now, it only accepts a single options argument, which can be a snowflake or an options object that may include an id property.

AnnouncementChannel

AnnouncementChannel#addFollower() now returns FollowedChannelData instead of a snowflake. This helps to expose the created webhook id in the target channel.

BaseInteraction

BaseInteraction#isAnySelectMenu() has been removed. Use BaseInteraction#isSelectMenu() instead, which has been repurposed to accept all select menu component types.

Client

Emojis

Client#emojis has been removed due to confusion with the introduction of application emojis and performance impact. Use the resolveGuildEmoji() utility function to get a cached guild emoji.

Ping

Client#ping has been added to replace the old WebSocketManager#ping. This will be null when the heartbeat from the gateway is yet to be received.

Premium sticker packs

Client#fetchPremiumStickerPacks() has been removed. Use Client#fetchStickerPacks() instead.

Ready event

client.on("") has been removed. "clientReady" is the replacement. If you used client.on(Events.ClientReady), you do not need to change anything.

Shard disconnect event

client.on("shardDisconnect") has been removed as the WebSocket manager replaces this functionality.

Shard error event

client.on("shardError") has been removed as the WebSocket manager replaces this functionality.

Shard ready event

client.on("shardReady") has been removed as the WebSocket manager replaces this functionality.

Shard reconnecting event

client.on("shardReconnecting") has been removed as the WebSocket manager replaces this functionality.

Shard resume event

client.on("shardResume") has been removed as the WebSocket manager replaces this functionality.

Webhook update event

client.on("webhookUpdate") has been removed. "webhooksUpdate" is the replacement. If you used client.on(Events.WebhooksUpdate), you do not need to change anything.

WebSocket

The underlying WebSocket behaviour has changed. In version 14, this was a non-breaking implementation of ws. Now, it is fully integrated. See these pull requests for more information:

ClientEvents

ClientEvents type has been removed. Use ClientEventTypes instead. This change ensures consistency with the rest of the event types across the library.

ClientOptions

Removed ClientOptions#shards and ClientOptions#shardCount in favor of ClientOptions#ws#shardIds and ClientOptions#ws#shardCount.

ClientUser

ClientUser#setPresence() now returns a promise which resolves when the gateway call was sent successfully.

ClientPresence

ClientPresence#set() now returns a promise which resolves when the gateway call was sent successfully.

CommandInteractionOptionResolver

CommandInteractionOptionResolver#getFocused()'s parameter has been removed. AutocompleteFocusedOption will always be returned.

Constants

DeletableMessageTypes has been removed. Use UndeletableMessageTypes instead.

DiscordjsErrorCodes

The following error codes have been removed as they either have no use or are handled in another package instead:

WSCloseRequested
WSConnectionExists
WSNotOpen
ManagerDestroyed
ShardingInvalid
ShardingRequired
InvalidIntents
DisallowedIntents
ButtonLabel
ButtonURL
ButtonCustomId
SelectMenuCustomId
SelectMenuPlaceholder
SelectOptionLabel
SelectOptionValue
SelectOptionDescription
UserBannerNotFetched
ImageFormat
ImageSize
SplitMaxLen
MissingManageEmojisAndStickersPermission
VanityURL
InteractionEphemeralReplied

Emoji

Image URL is now dynamic

Emoji#imageURL() now dynamically handles the extension. Previously, you would have to do this:

emoji.imageURL({ extension: emoji.animated ? 'gif' : 'webp' });

Now, you can simply do this:

emoji.imageURL();

Emoji URL getter removal

Emoji#url has been removed. To allow more granular control of the returned extension, Use Emoji#imageURL() instead.

EventEmitter

BaseClient, Shard, ShardingManager, and Collector now extend AsyncEventEmitter instead of EventEmitter. This comes from @vladfrangu/async_event_emitter.

Events

Events.ShardError has been removed.
Events.ShardReady has been removed.
Events.ShardReconnecting has been removed.
Events.ShardResume has been removed.
Events.WebhooksUpdate now returns a string of "webhooksUpdate". Previously, it returned "webhookUpdate". This is to bring it in line with the name of Discord's gateway event (WEBHOOKS_UPDATE).
Events.ClientReady now returns a string of "clientReady". Previously, it returned "ready". This is to ensure there's no confusion with Discord's READY gateway event.

Formatters

This utility has been removed. Everything in this class is redundant as all methods of the class can be imported from discord.js directly.

import { Formatters } from 'discord.js'; 
import { userMention } from 'discord.js'; 

Formatters.userMention('123456789012345678'); 
userMention('123456789012345678');

Guild

Removed Guild#shard as WebSocket shards are now handled by @discordjs/ws.

GuildApplicationCommandManager

GuildApplicationCommandManager#fetch() method has been updated for consistency with other managers. Previously, it accepted two parameters: id (a snowflake or an options object) and an options object. Now, it only accepts a single options argument, which can be a snowflake or an options object that may include an id property.

GuildAuditLogs

GuildAuditLogsEntry.Targets.All has been removed. It was not being used.

GuildBanManager

GuildBanManager#create() no longer accepts deleteMessageDays. This is replaced with deleteMessageSeconds.

GuildChannelManager

GuildChannelManager#addFollower() now returns FollowedChannelData instead of a snowflake. This helps to expose the created webhook id in the target channel.

GuildMemberResolvable

GuildMemberResolvable type has been removed. It was defined as GuildMember | UserResolvable, but UserResolvable already includes GuildMember. Use UserResolvable instead.

MessageManager

MessageManager#crosspost() has been moved to GuildMessageManager. This means it will no longer be exposed in DMMessageManager.

IntegrationApplication

IntegrationApplication#hook has been removed.

InteractionResponse

InteractionResponse has been removed. This class was encountered when responding to an interaction without fetchReply to allow ease of creating interaction collectors. This is no longer necessary as withResponse exposes the message.

InteractionResponses

Ephemeral option removal

Previously, you would respond to an interaction ephemerally like so:

// Way 1:
await interaction.reply({ content: 'This is an ephemeral response.', ephemeral: true });

// Way 2:
await interaction.reply({ content: 'This is an ephemeral response.', flags: MessageFlags.Ephemeral });

There are two ways to achieve the same behaviour, so the "helper" option has been removed. In this case, that would be ephemeral, as all that did was assign MessageFlags.Ephemeral internally.

Fetch reply option removal

fetchReply has been removed in favor of withResponse. If you were using the fetchReply option or fetching the response of an interaction, it is recommended to use withResponse instead, as the message is exposed without an additional API call:

const message = await interaction.reply({ content: 'Hello!', fetchReply: true }); 
const response = await interaction.reply({ content: 'Hello!', withResponse: true }); 
const { message } = response.resource;

Premium response type

Discord no longer supports the PREMIUM_REQUIRED interaction response type. In the past, you would have done this:

if (!premiumLogicCheck) {
	// User does not have access to our premium features.
	await interaction.sendPremiumRequired();
	return;
}

await interaction.reply('You have access to our premium features!');

However, you would have already noticed that this no longer works, so this method has been removed. Sending a premium button has been the replacement ever since.

Invite

Invite#stageInstance has been removed.

InviteStageInstance

InviteStageInstance has been removed.

Message

Message#interaction has been removed. Use Message#interactionMetadata instead.

MessagePayload

MessagePayload#isInteraction no longer serves a purpose and has been removed.

NewsChannel

NewsChannel has been renamed to AnnouncementChannel.

PermissionOverwrites

PermissionOverwrites.resolve() previously relied on cache if a snowflake was passed. This method no longer relies on cache and instead requires an explicit type if supplied.

RoleManager

RoleManager#fetch() used to return null when fetching a role that did not exist. This logic has been removed and will throw an error instead.

SelectMenuBuilder

SelectMenuBuilder has been removed. Use StringSelectMenuBuilder instead.

SelectMenuComponent

SelectMenuComponent has been removed. Use StringSelectMenuComponent instead.

SelectMenuInteraction

SelectMenuInteraction has been removed. Use StringSelectMenuInteraction instead.

SelectMenuOptionBuilder

SelectMenuOptionBuilder has been removed. Use StringSelectMenuOptionBuilder instead.

ShardClientUtil

ShardClientUtil#ids and ShardClientUtil#count have been removed in favor of Client#ws#getShardIds() and Client#ws#getShardCount().

StageInstance

StageInstance#discoverableDisabled has been removed.

TeamMember

TeamMember#permissions has been removed. Use TeamMemberManager#role instead.

TextBasedChannel

TextBasedChannel#bulkDelete() could return a collection containing undefined values. This was because in order to return these messages, the cache must be checked, especially when only snowflakes were provided. The return type of this method has thus changed to only return an array of snowflakes that were bulk deleted.
