I’ve just updated my discord.js from v13 to v14 and there are many errors.
Errors with intents:

Answer
Discord.js v14 includes many breaking changes. It now requires Node 16.9 or higher to use, so make sure you upgrade to the latest LTS version.
This version of v14 uses the Discord API v10.
Errors with intents:
// v13const client = new Client({ intents: [ Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES, ],});// ORconst client = new Client({ intents: ['GUILDS', 'GUILD_MESSAGES'],});// v14const { Client, GatewayIntentBits } = require('discord.js');const client = new Client({ intents: [ GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages, ],});For a full list of GatewayIntentBits, you can read this answer.
Errors with interactions:
Some interaction type guards have been removed. You can compare interaction.type against the InteractionType enum instead.
const { InteractionType } = require('discord.js');// v13if (interaction.isCommand()) {}// v14if (interaction.type === InteractionType.ApplicationCommand) {}// v13if (interaction.isAutocomplete()) {}// v14if (interaction.type === InteractionType.ApplicationCommandAutocomplete) {}// v13if (interaction.isMessageComponent()) {}// v14if (interaction.type === InteractionType.MessageComponent) {}// v13if (interaction.isModalSubmit()) {}// v14if (interaction.type === InteractionType.ModalSubmit) {}Errors with channels:
Some channel type guards have been removed. To narrow channels, you can compare channel.type to a ChannelType enum instead.
const { ChannelType } = require('discord.js');// v13if (message.channel.isText()) {}// v14if (channel.type === ChannelType.GuildText) {}// v13if (message.channel.isVoice()) {}// v14if (channel.type === ChannelType.GuildVoice) {}// v13if (message.channel.isDM()) {}// v14if (channel.type === ChannelType.DM) {}// v13if (message.channel.isCategory()) {}// v14if (channel.type === ChannelType.GuildCategory) {}For a full list of ChannelTypes, you can read this answer.
Also, there are some new type guards:
channel.isDMBased();channel.isTextBased();channel.isVoiceBased();Errors with builders and embeds:
MessageEmbed has been renamed to EmbedBuilder.
// v13const embed = new MessageEmbed();// v14const { EmbedBuilder } = require('discord.js');const embed = new EmbedBuilder();MessageComponents have been renamed; they no longer have the Message prefix and now have a Builder suffix.
// v13const button = new MessageButton();// v14 const { ButtonBuilder } = require('discord.js');const button = new ButtonBuilder();// v13const actionRow = new MessageActionRow();// v14 const { ActionRowBuilder } = require('discord.js');const actionRow = new ActionRowBuilder();// v13const selectMenu = new MessageSelectMenu();// v14const { SelectMenuBuilder } = require('discord.js');const selectMenu = new SelectMenuBuilder();// v13const textInput = new TextInputComponent();// v14const { TextInputBuilder } = require('discord.js');const textInput = new TextInputBuilder();Errors with enums:
Any areas that used to accept a string or number type for an enum parameter will now only accept exclusively numbers.
// Wrongnew ButtonBuilder() .setCustomId('verification') .setStyle('PRIMARY')// Fixedconst { ButtonStyle } = require('discord.js');new ButtonBuilder() .setCustomId('verification') .setStyle(ButtonStyle.Primary)// Wrongnew TextInputBuilder() .setCustomId('verification') .setStyle('SHORT')// Fixedconst { TextInputStyle } = require('discord.js');new TextInputBuilder() .setCustomId('verification') .setStyle(TextInputStyle.Short)Errors with activity types: setPresence activity type in discord.js v14 can only be set to “PLAYING”
If message.content doesn’t have any value, add the GatewayIntentBits.MessageContent enum to your intents array
