Interactions and Command handler 4 Dummies
With npm
npm i ic4d
with yarn
yarn add ic4d
const ic4d = require("ic4d");
// or
const {
/* Classess you need seprated by a comma */
} = require("ic4d");
and for yall ts lovers (I tried using this in ts and damn is it hard work.)
import * as ic4d from "ic4d";
// or
import /* Classes and/or Interfaces you need separated by a comma */ "ic4d";
If any method/function has no return documentation, it returns void.

Here's the example bot if you don't like reading
require("dotenv").config();
const { Client, IntentsBitField } = require("discord.js");
const path = require("path");
const { CommandHandler, ReadyHandler } = require("ic4d");
const commandsPath = "commands";
const runFlags = {
devs: ["671549251024584725"],
testGuildId: "808701451399725116",
};
const client = new Client({
intents: [
IntentsBitField.Flags.Guilds,
IntentsBitField.Flags.GuildMessages,
],
});
const handler = new CommandHandler(
client,
path.join(__dirname, "commands"),
runFlags
);
const ready = new ReadyHandler(
client,
async (client) => {
console.log(`${client.user.tag} is ready!`);
},
async () => {
await handler.registerCommands();
}
);
(async () => {
await handler.handleCommands();
ready.execute();
})();
client.login(process.env.TOKEN);
Ready handler is a handler that runs a set of functions when the bot starts.
client
: Client- Discord.js Client Instance
...functions
: ((client?: Client) => Promise<void> | void )[] = []- Functions to run when the
execute()
method is called, and the ready event has been emitted. Functions may take one parameter (client) or none.
- Functions to run when the
const { ReadyHandler } = require("ic4d");
const ready = new ReadyHandler(
client,
(client) => {
console.log(`${client.user.tag} is ready!`);
},
() => {
console.log("Lol another function");
}
);
Start listening for the bot's ready event and execute functions once the event is called.
const ready = new ReadyHandler(client, ...)
ready.execute()
Command Handler, which handles slash command creation, deletion, editing and running of slash commands
client
: Client- Discord.js Client Instance
path
: string- Path in which your exported command objects are stored. The handler will not work if you do not use path.
runFlags
: RunFlags- (optional) Command Reader Options
loaderOptions
: LoaderOptions- (optional) Command Loader Options
const { CommandHandler } = require("ic4d");
const path = require("path");
const handler = new CommandHandler(client, path.join(__dirname, "commands"));
(asynchronous function)
logAll
: boolean- (optional) Log command even if no change was performed.
serverId
: string- (optional) Register all commands in a specific server. if not provided it will be application wide
const handler = new CommandHandler(client, path.join(__dirname, "commands"));
async () => {
await handler.registerCommands();
};
(asynchronous function)
...middleWare
: ( ( commandObject: Object, interaction?: ChatInputCommandInteraction ) => number | Promise )[]- Functions to run before a command is run.
const handler = new CommandHandler(client, path.join(__dirname, "commands"));
const blacklisted = ["302983482377931"];
const blacklist = (commandObject, interaction) => {
if (commandObject.blacklist && blacklisted.includes(interaction.user.id)) {
interaction.reply({
content: this.readerOptions.onlyDev,
ephemeral: true,
});
return 1;
}
return 0;
};
await handler.handleCommands(blacklist);
Middleware is to define your own custom functions you want to run when a command is run by anyone. This can be a function to check for cooldown or function to add XP to a user.
Middleware that the package already contains is :
- Check to see if developer command
- Check to see if bot has sufficient permissions
- Check to see if user has sufficient permissions
The Middleware must take in these parameters
commandObject
: This is the commandObject that every command contains, this can check for the commands name, description, options, choices or a custom property you wishinteraction
(optional): If the middleware function requires you to take in interaction for some reason, here you go 😃
And should always return 1 or another number. If it returns 1 it counts as a fail so the function won't proceed. Another number returned is okay seen as a pass and the function continues. (If you don't understand, if a normal user tries to run a dev command, it will return 1, which means it wont run and their met with a fail message)
Here i define a command with the custom property canBeServerDisabled
const {SlashCommandManager} = require("ic4d");
const {SlashCommandBuilder} = require("discord.js");
const rob = new SlashCommandManager({
data: new SlashCommandBuilder()
.setName("rob")
.setDescription("Rob users")
execute: (interaction, client) => {
interaction.reply("bang bang!");
},
});
rob.canBeServerDisabled = true;
module.exports = rob
And in my middleware function i check if the command has been server disabled, if the property is enabled.
const isServerDisabled = (name) => {
// check to see if the function has been disabled by the server, if so return true, otherwise false.
};
const middleWare = (commandObject, interaction) => {
// you can name the parameters whatever you want, ass long as you remember which one is which.
if (
commandObject.canBeServerDisabled &&
isServerDisabled(commandObject.name)
) {
interaction.reply({
content: "This command is server disabled",
ephemeral: true,
});
return 1;
}
return 0;
};
handler.handleCommands(middleWare); // pass the function alone without brackets or its parameters, i'll do that magic
Set whether the ready handler should throw or emit errors. Defaults to false.
const handler = new CommandHandler(client, path.join(__dirname, "commands"));
handler.emitErrors(true);
// Listen for the error
handler.on("error", (msg) => {
// do something with the error message
});
Handler to handle interactions.
Context Menus work a bit differently then the other interactions, please refer to registerContextMenus()
-
client
: Client- Discord.js client
-
path
: string- Path to where interactions are stored.
-
loaderOptions
: LoaderOptions- (optional) Context Menu Loader Options
-
flags
: InteractionHandlerFlags- (optional) Interaction Handler Flags
const { InteractionHandler } = require("ic4d");
const path = require("path");
const interactions = new InteractionHandler(
client,
path.join(__dirname, "commands")
);
Start listening for all the available interactions. (Context Menus, Buttons, Select Menus and Modals)
authorOnlyMsg
: string- (optional) Message to display when a interacts with another user's interaction (onlyAuthor is set to true.)
...middleWare
: ((interaction?: Interaction) => number)[]- Functions to run before an interaction is run.
interactions.start();
Start listening for button interactions.
authorOnlyMsg
: string- (optional) Message to display when a user click's another user's button (onlyAuthor is set to true.)
...middleWare
: ((interaction?: Interaction) => number)[]- Functions to run before a button is run.
interactions.buttons();
Start listening for select menu interactions.
authorOnlyMsg
: string- (optional) Message to display when a user click's another user's select menu (onlyAuthor is set to true.)
...middleWare
: ((interaction?: Interaction) => number)[]- Functions to run before a select menu is run.
interactions.selectMenu();
Start listening for modal interactions. (After their registered)
...middleWare
: ((interaction?: Interaction) => number)[]- Functions to run before a modal is shown.
interactions.modals();
Start listening for context menu interactions. (After their registered)
...middleWare
: ((interaction?: Interaction) => number)[]- Functions to run before a context menu is run.
interactions.contextMenus();
Exactly like Command Middleware, where 1 will return and any number will continue execution. Only difference is here the only parameter you get is interaction.
function isAuthor(interaction) {
// the handler does this for you (check the InteractionObject) but im writing this as an example only.
const author = interaction.message.interaction.user.id;
const clicker = interaction.member.user.id;
return clicker === author ? 1 : 0;
}
function lucky(interaction) {
// randdom one
return 1 == 1 ? 1 : 0; // will always return 1.
}
// some other code
interactions.buttons("This isn't your button!", isAuthor); // this will only run for buttons.
interactions.start(undefined, lucky); // will run for every interactions
(asynchronous function)
Registers Context Menus that are found in the path given tot he InteractionHandler.
logAll
: string- (optional) Log context menu even if no change was performed.
serverId
: string- (optional) Register all commands in a specific server. if not provided it will be application wide
await interactions.registerContextMenus();
This class represents a single command that is immediately exported from a file in the "commands"
directory of your choosing

An interface representing the configuration flags used for running commands in the bot.
This configuration is specifically used to control various runtime aspects of command execution.
Default value: undefined
The ID of the test guild for command testing purposes. If provided, commands will be deployed only to this guild.
Default value: []
An array of Discord user IDs (snowflakes) that have developer privileges.
Commands or functionalities restricted to developers will be accessible to users with IDs in this array.
Default value: "Only developers are allowed to run this command."
The message shown when a command restricted to developers is executed by a non-developer.
Default value: "Not enough permissions."
The message displayed when a user lacks the necessary permissions to execute a command.
Default value: "I don't have enough permissions."
The message displayed when the bot lacks the necessary permissions to execute a command.
const obj: RunFlags = {
testGuildId: "808701451399725116",
devs: ["671549251024584725"],
onlyDev: "Text to display when a user runs a developer command.",
userNoPerms: "Text to display when the user has insufficient permissions",
botNoPerms: "Text to display when the bot has insufficient permissions",
};
An interface that represents anything you can do with the commands when they are run, BUT before YOUR code executes.
Default value: false
Enable debugger mode. Prints(almost) everything that happens behind the scenes of course not with the API itself.
Default value: false
Disabling Logging of the Command Loader. Not advisable but hey it's your bot.
Default value: false
Whether or not this is the production version of the bot. If set to true, commands labelled isDev
will NOT be loaded. (Use the setDev()
method in SlashCommandManager)
Default value: false
Clears ALL application commands on startup. (Slash commands, User commands, and Message commands.)
Default value: false
When debugger mode is enabled, Either log to console or a file.
const obj: LoaderOptions = {
debugger: true,
production: true,
disableLogs: true,
};
An interface that represents anything you can do with the interactions when they are run, BUT before YOUR code executes.
Default value: false
Enable Debugger mode. Prints (almost) everything that happens behind the scenes of course not with the API itself.
Default value: false
Disabling Logging of the Context Menu Loader. Not advised but hey it's your bot. Default is false.
Default value: false
Clears Context Menus
Default value: false
When debugger mode is enabled, Either log to console or a file.
Interface that represents default string values for the loader to log to the console when it encounters a command/context menu.
Make sure you keep NAME
in the string or else you will not know what happened to which command.
If there is no log in the console for a specific command, then it has been loaded, there are no edits and it has not been deleted.
Note:
These have multiple default values, as context menus and commands are different.
What to show for context menus/commands that load in
What to show for context menus/commands that gets edited.
What to show for context menus/commands that gets deleted.
What to show for context menus/commands that gets skipped. (Deleted and still marked as deleted.)
What to show for context menus/commands that gets loaded, but has no changes
const obj: LoaderOptions = {
loadedNoChanges: "NAME was loaded. No changes were made to NAME.",
loaded: "NAME has been registered successfully.",
edited: "NAME has been edited.",
deleted: "NAME has been deleted.",
skipped: "NAME was skipped. (Command deleted or set to delete.)",
};
Type alias for the strings "selectMenu"
, "modal"
and "button"
Yes this did not need documenting, but here it is.
Here's the exact definition because I genuinely don't know how to explain this.
export type InteractionTypeStringsMap<U extends string> = U extends "modal"
? ModalSubmitInteraction
: U extends "selectMenu"
? AnySelectMenuInteraction
: U extends "button"
? ButtonInteraction
: never;
-
Files in the
commands
directory trying to be read as slash commmands by theCommandHandler
class.- Example: This function is in the
commands
direcotory as it is used by multiple commands, but is not a commands itself.
const function a(userBalance) { return userBalance > 0 ? true : false; } module.exports = a;
- The Command Reader will try to read it but error as it is not a command it can read, to avoid this, make sure you export the
isCommand
(Set to false) property with the function.
const function a(userBalance) { return userBalance > 0 ? true : false; } module.exports = {a, isCommand = false};
- Usually, the reader should skip over anything it can read, but if needed, this will immediately make it skip.
- Example: This function is in the
Huge credit to underctrl, Code would've not been possible if i did not watch his helpful discord.js tutorials! I had to give him credit because this package is based off moving all those files fromm his tutorial into one package.
He probably has a way better package, so go check his out!
