Regex Commands

Memes

Regex or regular expressions, is basically a way to match characters in a string.
Regex commands are commands that run if the following conditions are true:

• The command was not invoked normally.
• The command's regex matches the message.

Multiple regex commands/conditional commands can be triggered from one message.

import { Command } from "discord-akairo";
import { Message } from "discord.js";

export default class AyyCommand extends Command {
  constructor() {
    super("ayy", {
      regex: /^ayy$/i
    });
  }

  exec(message: Message): Promise<Message> {
    return message.reply("lmao");
  }
}

This command will trigger on any message with the content ayy, case-insensitive.
In args, the match property will be the result from message.content.match(/^ayy$/i).
The matches property will be the matches, if using a global regex.

As a Function

The regex option can also be a function.

import { Command } from "discord-akairo";
import { Message } from "discord.js";

export default class AyyCommand extends Command {
  constructor() {
    super("ayy", {
      category: "random"
    });
  }

  regex(message: Message) {
    // Do some code...
    return /^ayy$/i;
  }

  exec(message: Message): Promise<Message> {
    return message.reply("lmao");
  }
}
