Decorators

App

• MeoCord

  Declares the application class: its controllers, services, client options and what applies to every handler.

• Service

  Marks a class as a service, which controllers and other services inject by its type.

Controllers

• Controller

  Marks a class as a controller, whose methods handle commands, components, messages, reactions or events.

• UseTheme

  Sets part of the theme for a controller's handlers, or for one handler.

Handlers

• Autocomplete

  Suggests values for an option of a chat input command as the user types.

• Command

  Routes a command, a component or a modal submission to the method it decorates.

• CommandBuilder

  Marks a class as a command's builder, which describes the command MeoCord registers with Discord.

• MessageHandler

  Runs the method it decorates for every message a user sends, whatever it says.

• On

  Handles a discord.js client event every time it is emitted, on a controller or a service.

• Once

  Handles a discord.js client event the first time it is emitted only, on a controller or a service.

• ReactionHandler

  Runs the method it decorates when a reaction with an emoji is added to or removed from a message.

Params

• Inject

  Injects what a token provides into a constructor parameter.

Pipeline stages

• Catch

  Marks a class as an exception filter for the given error types.

• Cooldown

  Limits how often a handler runs, counted per user, server, channel or for everyone.

• Defer

  Acknowledges an interaction for its handler, then locks a component's message while the handler runs.

• Guard

  Marks a class as a guard, which decides whether a handler runs.

• Interceptor

  Marks a class as an interceptor, which wraps a handler to act before and after it.

• Observer

  Marks a class as a dispatch observer, told about every call once it has settled, for metrics and audit logs.

• Pipe

  Marks a class as a pipe, which turns one input value into what the handler works with.

• UseFilter

  Applies exception filters to a handler, or to every handler of a controller.

• UseGuard

  Runs guards before a handler, or before every handler of a controller.

• UseInterceptor

  Runs interceptors around a handler, or around every handler of a controller.

• UsePipe

  Runs pipes on one value of a handler's input, to turn it into what the handler works with.

• Validate

  Validates a handler's input with a Standard Schema before it runs.
