Yui

Versão em português

Almost like a daughter, it's a general purpose bot, called Yui I'm developing for discord with discord.js library, the name is inspired by the character Yui from the anime Sword Art Online, which at first is an A.I.

🤔 How to use in my server?

• Add the bot, just click in this LINK
  • You must be an administrator on some server
• Read the Docs of commands HERE
• Enjoy 😁

🧩 Running locally

Before all you must to be added the bot in your server, to do this follow the link

// Clone de repository
$ git clone https://github.com/miguelrisquelme/yui.git

// Install the dependencies
$ npm i

// Create and configure the file .env, follow the example on .env.example
~/.env

// Start the aplication
$ npm run dev

❌ Error Handling

For the error consoles to work, the folder structure has to be standardized, just follow these instructions:

• The command name must be the same as its folder name.

  /commands/${nameCommand}

  module.exports = {
    name: `${nameCommand}`,
    description: "Description Command",
    execute,
  };

• The name of the functions must be the same as the arguments passed after the command

  • > time ${args}
  • /commands/time/functions/${args}.js

Example Output:

      ❌ TypeError: message.channel.sen is not a function
      🦊 Input: '> time hours'
      ✨ Command: time
      🔥 Function: hours
      🧅 Possible Path: /commands/time/hours.js

The code of catch Error:

const error = require("../utils/handlers/errors/errors.handler");
...

catch (err) {
  const args = message.content.slice(prefix.length).trim().split(/ +/);
  console.error(`
      ❌ ${err.toString()}
      🦊 Input: '${message.content}'
      ✨ Command: ${args[0]}
      🔥 Function: ${args[1]}
      🧅 Possible Path: /commands/${args[0]}/${args[1]}.js
    `);
  console.error(err);
  error.handler(err, message);
}
