SLCommands Events

SLCommands comes with some custom events.

The databaseConnected, commandException and handlerReady events are enabled by default.

But there are one more event: commandDevsOnly that is only enabled when you set the useDefaultMessages property to false when creating the handler. It let you handle command checks the way you want.

handlerReady

This event is emitted once when the handler set up is done.

JavaScript

const { Event } = require('sl-commands')

/** ctx is a object containing the client and the handler instances */
new Event(
  'handlerReady', 
  (ctx) => {
    console.log(`The handler is ready!`)
  }
)

TypeScript

import { Event } from 'sl-commands'

/** ctx is a object containing the client and the handler instances */
new Event(
  'handlerReady', 
  (ctx) => {
    console.log(`The handler is ready!`)
  }
)

databaseConnected

This event is emitted whenever the database is sucessfully connected via SLCommands.

JavaScript

const { Event } = require('sl-commands')

/** ctx is a object containing the client and the handler instances */
new Event(
  'databaseConnected', 
  (ctx, connection, state) => {
    console.log(`The connection state is "${state}".`)
  }
)

TypeScript

import { Event } from 'sl-commands'

/** ctx is a object containing the client and the handler instances */
new Event(
  'databaseConnected', 
  (ctx, connection, state) => {
    console.log(`The connection state is "${state}".`)
  }
)

commandException

This is emitted whenever the handler detects any exception with the commands.

JavaScript

const { Event } = require('sl-commands')

/** ctx is a object containing the client and the handler instances */

/** interaction parameter can be undefined */
new Event(
  'commandException',
  (ctx, commandName, error, interaction) => {
    console.log(`Error in command ${commandName}.`, error)
  
    if (interaction) {
      interaction.reply({ content: 'Oops! An error occurred.' })
    }
  }
)

TypeScript

import { Event } from 'sl-commands'

/** ctx is a object containing the client and the handler instances */

/** interaction parameter can be undefined */
new Event(
  'commandException',
  (ctx, commandName, error, interaction) => {
    console.log(`Error in command ${commandName}.`, error)
  
    if (interaction) {
      interaction.reply({ content: 'Oops! An error occurred.' })
    }
  }
)

commandDevsOnly

This is emitted whenever some unauthorized user tries to use a devsOnly command.

JavaScript

const { Event } = require('sl-commands')

/** ctx is a object containing the client and the handler instances */
new Event(
  'commandDevsOnly', 
  (ctx, interaction) => {
    interaction.reply({ content: 'This command can only be used by my devs.' })
  }
)

TypeScript

import { Event } from 'sl-commands'

/** ctx is a object containing the client and the handler instances */
new Event(
  'commandDevsOnly', 
  (ctx, interaction) => {
    interaction.reply({ content: 'This command can only be used by my devs.' })
  }
)
