Nebucord - Discord WebSocket and REST API

This is another implementation of the Discord API. It implements an HTTP WebSocket client as well as a REST API.
An actual in use sample can be found on our Discord server: Nebulatien

If you need help or have questions, don't hestiate to contact Me. Best done if you join the above mentioned Discord server or (if you found something) create an issue in Github. Also pull request for fixes of course are welcome.

Of course not fully finished is it still able to do the most important things. This includes:

• Nebucord WebSocket API

  • Setup and run bot(s)
  • Set status for bots
  • Simple control commands
  • Callback classes to intercept Discord gateway events
  • Changing default internal command behaviours
  • Setting user id's for bot controlling
  • Configurable by parameter or by .ini file
  • Customable gateway intents
  • Application and interactions API

• Nebucord REST API

  • Model oriented interface on data receiving
  • Application and interactions API
  • Followup Messages for interactions
  • Complete Discord REST API
  • Configurable by parameter or by .ini file

• What's missing

  • Many error checking
  • Way more better logging and debugging options
  • Multithreading (if applicable, thanks to bitnykk for the idea)

Default and available parameters

Parameter	Config name	INI config name	Default value
Bot token	token	bottoken	(string)empty
ACL user snowflakes	ctrluser	acl	(array)[]
WS connection retries	wsretries	websocket.retries	(integer)3
Default GW intent bitmask*	intents	intents.*	(integer)3276541 / (boolean)true*
DM on failures	dmonfailures	websocket.dmonfailures	(boolean)true

*Note:
The intent bitmask defaults to be everything is true except GUILD_MEMBERS, GUILD_PRESENCES, GUILD_MESSAGES and MESSAGE_CONTENT. These four options has to be manual set to true and they have to be activated in the Bot preferences on the Discord application management webpage. The bitmask is 3276799 if everything set to true or for config as parameter.

Note:
Configuration by parameter has priority to configuration by .ini file.

Requirements

Additional Composer packages are required in order to run Nebucord.
Of course these can also be installed without Composer, but you have to include the SPL autoloader of the packages as well.

The recommended way is to use Composer.

Package informations:

• Connfetti-IO on Github
• Connfetti-INI on Github

Install

By composer:

user@linux:~# composer require eurobertics/nebucord

---

By Docker (more information can be found on Nebucord Docker Hub):

user@linux:~# docker pull eurobertics/nebucord:latest

---

By GitHub Packages (more information can be found on GitHub Pulling container images):

docker pull ghcr.io/eurobertics/nebucord:latest

Note:
If you want use .ini configuration, you have to put your .ini File (nebucord.ini i. e.) in the mounted directory for your Docker instance and set the path to the path of the docker working directory. You can find more information about this on the Nebucord Docker Hub Page.

---

By GIT:
Simple clone this repository and use the native autoloader file in ./src Directory.

user@linux:~# git clone https://github.com/Eurobertics/Nebucord.git

Note: If you use the library without composer, you just can include the native autoloader:

include "src/nebucordAutoloader.php";

Note: You have to include the native autoloader of the dependencie packages as well. See package dependencies above.

Example usage - WebSocket API

The WebSocket API is designed to run as a PHP CLI program.

Usage websocket API, minimalistic example:

<?php
include "vendor/autoload.php"; // Composer autloader

use Nebucord\Nebucord;

$nebucord = new Nebucord(['token' => 'your_bot_token', 'ctrlusr' => ['controluser-snowflake1', 'controluser-snowflake2']]);
$nebucord->bootstrap()->run();

'your_bot_token': The auth token of your bot (from the Discord Dev-Portal)

'controluser-snowflake': The snowflake of Discord user(s) who can issue control commands such like 'shutdown' to the bot.

Of course this only starts the bot and this one sits there and does nothing.

A more complex example:

<?php
include "vendor/autoload.php"; // Composer autoloader

use Nebucord\Nebucord;

class MessageInterceptorClass {
    public function onMessageReceive($evt) {
        // $evt is a model with all data from the gateway if a message create
        // event is received
        
        echo $evt->content; // returns the message
    }
}

$nebucordEventTable = \Nebucord\Events\EventTable::create();
$nebucordEventTable->addEvent(new MessageInterceptorClass, "onMessageReceive", \Nebucord\Base\StatusList::GWEVT_MESSAGE_CREATE);

$nebucord = new Nebucord(['token' => 'your_bot_token', 'ctrlusr' => ['controluser-snowflake1', 'controluser-snowflake2']]);
$nebucord->bootstrap()
    ->setEventTable($nebucordEventTable)
    ->run();

The above example prints out every message which was seen by the bot (based on the bot roles on the Discord guild). "Seen" means all CREATE_MESSAGE events from the Discord gateway.

Now on a console:

user@linux:~# php -f <your_php_file>.php

Example usage - REST API

Basic usage for sending a message:

<?php
include "vendor/autoload.php"; // Composer autloader

use Nebucord\NebucordREST;

$nebucordREST = new NebucordREST(['token' => 'your_bot_token']);
$message_model = $nebucordREST->createRESTExecutor()->createRESTActionFromArray(
   \Nebucord\REST\Base\RestStatusList::REST_CREATE_MESSAGE,
   [
       'channel_id' => 123123123123,
       'content' => "message"
   ]
);

"$message_model" is an object with the answer from the REST gateway.

Basic usage for receiving guild channels:

<?php
include "vendor/autoload.php";

use Nebucord\NebucordREST;

$nebucordREST = new NebucordREST(['token' => 'your_bot_token']);
$channels = $nebucordREST->createRESTExecutor()->createRESTActionFromArray(
   \Nebucord\REST\Base\RestStatusList::REST_GET_GUILD_CHANNELS,
   [
       'guild_id' => 123123123123123,
   ]
);

"$channels" is an array of channel models for processing.

createRESTExecutor() returns an object which can be re-used for creating REST request.
It is also possible to create a REST request with createRESTAction(string Nebucord_RESTStatus::REST_*, ModelREST $restmodel) instead of createRESTActionFromArray(string Nebucord_RESTStatus::REST_*, array $restparams) and pass a predefined ModelREST object with all params for the REST gateway.
