Augur - Discord bot framework

Augur is a Discord bot framework, utilizing the discord.js library.

Change Log

As of version 2.3.0, Augur uses Discord.js v12.2 and requires Node 14+.

2.3.0 introduces several new features:

• AugurCommand.parseParams
• AugurCommand.options
• AugurInteractionCommand
• AugurModule.addInteraction()
• DiscordInteraction
• DiscordInteractionResponse
• ModuleManager.InteractionManager

2.0.1 automatically unloads all modules prior to executing client.destroy().

2.0.8 includes various bugfixes.

Installation

npm install --save augurbot discord.js

The Augur Client

Within your base file, require augurbot and create a new instance of AugurClient:

const {AugurClient} = require("augurbot");
const client = new AugurClient(config, options);

client.login();

The AugurClient will create the Discord Client, log it in using the token provided in config.token, listen for events, and process commands. Any gateway intents are automatically calculated based on config.events.

The config Object

Minimum required properties in config include:

• events (array): An array of discord.js events to process, including message and messageUpdate, if your bot will be processing message commands. Gateway intents will be automatically calculated based on the events supplied.

Additional optional properties include:

• db (object): An object, including a model property which is the path to your database model, relative to the base file.

• prefix (string): A default prefix for commands. Defaults to !.

• processDMs (boolean): Whether to process messages in DMs. Defaults to true.

• token (string): Your bot's Discord token to log in. If provided in the config object, it does not need to be passed when client.login() is called. If omitted, it must be passed with client.login(token) when logging in.

• Any other properties you wish to be able to access from your command modules.

The options Object

The options object is optional, but may include:

• clientOptions (object): An object containing options to be passed to the new Discord.Client(). Gateway intents are automatically calulated based on config.events. If you would like to override the calculated intents, provide your own intents as usual for Discord.js.

• commands (string): A directory, relative to the base file, containing any command modules you wish to automatically load.

• errorHandler: A function accepting error and message as its arguments. This will replace the default error handling function.

• parse (async function): An asynchronous function accepting message as its argument, returning an object with command and suffix properties. This will replace the default parsing function. (Useful in case different servers use different prefixes, for example.)

AugurClient Properties

Properties of the AugurClient class:

• augurOptions (object): The options object passed to the client upon initialization.

• clockwork (ClockworkManager extends Collection):

  A collection of functions to be run by an interval.

  • register(AugurModule): Registers clockwork functions from a Module. Automatically called by client.moduleHandler.register(AugurModule).
  • unload(filepath): Unload a clockwork function from memory. Automatically called by client.moduleHandler.unload(filepath).

• commands (CommandManager extends Collection):

  A collection of commands, keyed by command name.

  • aliases (Collection): Collection of commands, keyed by alias.
  • client (AugurClient): The client.
  • commandCount (Number): Integer of how many commands have been executed via commands.execute().
  • execute(commandName, message, suffix) (async function): Execute a command function. Automatically called by the event handler.
  • register(AugurModule) (function): Registers commands from a Module. Automatically called by client.moduleHandler.register(AugurModule).

• config: The config object passed to the AugurClient.

• db: Your loaded database model.

• events (EventManager extends Collection):

  A collection of event handlers, keyed by event then keyed by filepath.

  • register(AugurModule): Registers event handlers from a Module. Automatically called by client.moduleHandler.register(AugurModule).

• interactions (InteractionManager extends Collection):

  A collection of interaction event handlers for slash commands, keyed by interaction id. NOTE: As of Augur 2.3.0, Augur does not handle creating the data object to create or edit an interaction. See the Discord Developer Portal for details on the data object required to register a command.

  • register(AugurModule) (function): Registers interaction commands from a Module. Automatically called by client.moduleHandler.register(AugurModule).
  • createGlobalCommand(data) (function): Registers a new global slash command with Discord.
  • createGuildCommand(guildId, data) (function): Registers a new guild slash command with Discord.
  • deleteGlobalCommand(commandId) (function): Deletes an existing global slash command with Discord.
  • deleteGuildCommand(guildId, commandId) (function): Deletes an existing guild slash command with Discord.
  • editGlobalCommand(commandId, data) (function): Edits an existing global slash command with Discord.
  • editGuildCommand(guildId, commandId, data) (function): Edits an existing guild slash command with Discord.
  • getGlobalCommands(commandId) (function): Fetches an array of all global slash commands (when no commandId provided) or a single global slash command (when commandId provided).
  • getGuildCommands(guildId, commandId) (function): Fetches an array of all guild slash commands (when no commandId provided) or a single guild slash command (when commandId provided).

• moduleHandler (ModuleManager):

  Helper methods for loading/unloading/reloading Augur AugurModules.

  • register(AugurModule, data): Register the module with optional data.
  • reload(filepath): Reload a module from a filepath, reregistering the module with data supplied by the command's .unload() method.
  • unload(filepath): Unload a module from memory.

AugurClient Methods

Methods of the AugurClient class:

• errorHandler(error, message): Error handling function.

• parse(message): Parse a message into its command name and suffix. Returns an object containing command (string) and suffix (string).

Command File Structure

The basic file structure:

const Augur = require("augurbot");
const Module = new Augur.Module();

// Add commands, interactions, event handlers, etc. as necessary.

module.exports = Module;

In between, you can add one or more commands and event handlers, as well as a clockwork and unload function.

Module properties include:

• config: Contents of the config object loaded with the AugurClient.

• db: The loaded database model.

• client: The Augur client which loaded the command module.

All of the following methods are chainable:

Clockwork

The function passed to the .setClockwork() method should return an interval which will continue to run in the background. The interval is cleared and reloaded when the module is reloaded. Note that the clockwork function is run after the intialization function.

Module.setClockwork(function() {
  return setInterval();
});

Commands

The .addCommand() method defines a new bot command.

Module.addCommand({
  name: "commandname",
  process: async (msg, suffix) => {},
  aliases: [],
  category: "",
  description: "",
  enabled: true,
  hidden: false,
  info: "",
  options: {},
  parseParams: false,
  permissions: async (msg) => {},
  syntax: ""
});

• name (string): Required. A string for the name of the command.
• process (function): Required. The function to run when the command is invoked. This accepts either:
  • If parseParams is false, (message, suffix); a Discord.Message object and a suffix string of the remainder of the command supplied by the user; or
  • If parseParams is true, (message, ...params); a Discord.Message object and a list of parameters suppried by the user.
• aliases (array of strings): An array of strings that can can be used as alternate names for the command.
• category (string): A category name, for convenience in organizing commands. Defaults to the filename of the module.
• description (string): A short string for a brief overview of the command.
• enabled (boolean): Whether the command is able to run. Defaults to true.
• hidden (boolean): A boolean for whether you want to hide the command in your help functions. Defaults to false.
• info (string): A longer string with more details about the command's usage.
• options (object): An object of custom options that the developer may wish to use (e.g. in parsing messages).
• parseParams (boolean): Determines whether to split the command suffix before passing the parameters to the process function. Defaults to false.
• permissions (function): A function used to determine whether the user has permission to run the command. Accepts a Discord.Message object.
• syntax (string): A string describing command syntax.

Events

The .addEvent() method adds an event handler for the various Discord.js events.

Module.addEvent("eventName", function(...args) {});

Interactions

The .addInteraction() method defines an interaction for slash commands.

Module.addInteraction({
  id: "interactionId",
  process: async (interaction) => {},
  category: "",
  description: "",
  enabled: true,
  hidden: false,
  info: "",
  name: "slashCommandName",
  options: {},
  permissions: async (interaction) => {},
  syntax: ""
});

• id (string): Required. The interaction ID for the slash command.
• process (function): Required. The function to run when the slash command is invoked. This accepts a DiscordInteraction object.
• category (string): A category name, for convenience in organizing slash commands. Defaults to the filename of the module.
• description (string): A short string for a brief overview of the slash command.
• enabled (boolean): Whether the slash command is able to run. Defaults to true.
• hidden (boolean): A boolean for whether you want to hide the slash command in your help functions. Defaults to false.
• info (string): A longer string with more details about the slash command's usage.
• name (string): The name of the slash command.
• options (object): An object of custom options that the developer may wish to use (e.g. in parsing messages).
• permissions (function): A function used to determine whether the user has permission to run the slash command. Accepts a DiscordInteraction object.
• syntax (string): A string describing command syntax.

Initialization

The .setInit(data) method accepts a function to run on module initialization. The data parameter will have a null value on the first run, and will contain the returned by the function defined with the .setUnload() method on subsequent reloads of the module.

Module.setInit(function(data) {});

Unloading

The function passed to the .setUnload() method will be run when unloading or reloading the module.

Module.setUnload(function() {});

Supplemental Classes

As of Augur 2.3.0, Discord.js does not yet support interactions (slash commands). Once Discord.js supports interactions, the following will likely be removed in favor of official library support. As a temporary fix, the following classes are used within Augur to facilitate slash command use:

DiscordInteraction

A DiscordInteraction represents the data object provided by the Discord API on the interactionCreate event. See the Discord Developer Portal for additional information. Properties and methods include:

• client (AugurClient): The Client that received the interaction.

• id (snowflake): id of the interaction

• type (InteractionType): the type of the interaction

• data (ApplicationCommandInteractionData): the command data payload

• name (string): the name of the interaction being used, found in .data.name

• commandId (snowflake): the id of the interaction being used, found in .data.id

• options (array): options found in .data.options

• guild (Discord.Guild): the Guild object representing the Guild where the command was run, if found

• channel (Discord.Channel): the Channel object representing the Channel where the command was run, if found

• member (Discord.GuildMember): the GuildMember object representing the member running the command, if in a Guild

• user (Discord.User): the User object representing the user running the command, if found

• token (string): a continuation token for responding to the interaction

• version (int) always 1

• deferred (boolean): whether the interaction has been "deferred" and waiting for a full response.

• defer(): Defers the interaction response

• createResponse(content, options): Creates an initial response or edits a deferred response.

• createFollowup(content, options): Creates a followup response.

• deleteResponse(response): Deletes the identified interaction response, deleting the original response if no response/id is passed to the method.

• editResponse(content, options, response): Edits the identified interaction response, editing the original response if no response/id is passed to the method.

DiscordInteractionResponse extends Discord.Message

• interaction (DiscordInteraction): The interaction to which the response is related.
• followup(content, options): Convenience method calling DiscordInteraction.createFollowup(content, options).
