Some time ago, I posted an article about a module allowing the creation of Discord bots using the TypeScript decorators.
Well today, I'm pleased to announce the version 2.0 of this module!
This version includes two new very useful decorators which are @Command and @Guard.
@Command 📟
First of all, @Command allows you to simplify the management of the commands launched by the user in the chat, here is a small example of what this gives:
import {
Discord,
Command,
CommandMessage
}
@Discord({ prefix: "!" })
abstract class App {
// Executed when the user send "!hello"
@Command("hello")
hello(message: CommandMessage) {
message.reply("Hello!")
}
@CommandNotFound()
hello(message: CommandMessage) {
message.reply("Command not found :(")
}
}
@Guard ⚔️
The @Guard decorator, on the other hand, allows functions to be executed before the event or command is executed, e.g. to check whether a condition is satisfied in order to block the event if it's not.
import {
Discord,
Command,
CommandMessage,
Guard
}
function IsUserMaster(message: CommandMessage) {
return message.author.username === "TheMaster139";
}
@Discord({ prefix: "!" })
abstract class App {
// Executed when the user send "!hello" and if user's username is "TheMaster139"
@Guard(IsUserMaster)
@Command("hello")
hello(message: CommandMessage) {
message.reply("Hello!")
}
@CommandNotFound()
hello(message: CommandMessage) {
message.reply("Command not found :(")
}
}
Thanks for reading! 😊
But that's not all, for more information you can go to the GitHub repository.
You can also join the Discord server.
