Discord.js v14 Code Breakage: A Comprehensive Guide to Fixing Common Errors

The recent update to Discord.js v14 has introduced several breaking changes that can cause errors in existing code. Here's a thorough explanation of the most common errors and how to resolve them:

Errors with Message and Interaction Events

• Error: Message and interaction events no longer fire.
• Solution: Use the new messageCreate and interactionCreate events instead.

Errors with Intents

• Error: Intents are now enum values rather than strings or numbers.
• Solution: Use the GatewayIntentBits enum from the discord.js package to set the correct intents.

Errors with Interactions

• Error: Interaction type guards have been removed.
• Solution: Compare the interaction.type property to the InteractionType enum instead.

Errors with Channels

• Error: Channel type guards have been removed.
• Solution: Compare the channel.type property to the ChannelType enum.

Errors with Builders and Embeds

• Error: Constructors for builders and embeddings have changed names.
• Solution: Use the new EmbedBuilder, AttachmentBuilder, and component builders with the Builder suffix.

Errors with Enums

• Error: Enum parameters must now be numeric.
• Solution: Use the appropriate enum values from the discord.js package.

Additional Changes:

• Node 16.9 or higher is now required.
• Activity type in setPresence is now limited to "PLAYING."
• Consider adding GatewayIntentBits.MessageContent if message.content is expected to be used.
