Message Create Event

The messageCreate event in Discord.js is triggered whenever a new message is created in a text channel. This event is useful for building features such as command handling, automated responses, and various message-based interactions. By listening to this event, you can execute specific code whenever a user sends a message in your Discord server.

Now inside the client folder add our messageCreate.ts file

- - ready.ts
  - messageCreate.ts

Create `messageCreate.ts`

Now, we have to write the logic for our message create event. This file will contain the logic that should be executed whenever a new message is created. Typically, you will check if the message starts with a command prefix and then execute the corresponding command.

This message event handler comes with developer commands, bot permissions, and user permission checks built-in.

🚫

At this moment, you may get some errors because we haven't created our logger function yet! For the logger function, please refer to the logging guide.

Alright we have done, now let's go further!
