Discord Bot Express

Discord Bot Framework for command management inspired by Express written in Typescript

Quick Start

$ npm install discord.js
$ npm install discord-bot-express

Setting up the commands

Check here for better example

var CommandManager=require("discord-bot-express").CommandManager;
const {NotABot}=require("discord-bot-express").BotMiddleware;

CommandManager.setPrefix("Bot "); //Bot prefix not required
CommandManager.use(NotABot); //Middleware that prevents bot from calling itself

// :<name> defines a parameter for the command with the given name
CommandManager.command("tts :langCode", setLanguage);  //Example
// :<name>* defines a multi-parameter for the command with the given name
CommandManager.command("tts :text*", speak);  //Example
// ?<name> defines a optional parameter for the command with the given name
CommandManager.command("news ?day", news);  //Example
// ?<name>* defines a multi-optional parameter for the command with the given name
CommandManager.command("news ?withWords*", newsSearch);

//With annonymous function
CommandManager.command("pick :option1 or :option2", function(msg, client, params){
    var options=[params.option1, params.option2];
    var rng=(Math.floor(Math.random() * 2) + 1) -1;
    msg.channel.send(options[rng]);
});

//with declared function
function sayHello(msg,client,params){
  msg.channel.send("Hello");
}
CommandManager.command("say hello", sayHello)
.setDescription("Says Hello");

//Example of middleware that prevents non shinobi users to use command
CommandManager.command("slap :user",Permissions.isShinobi, slap)
.setDescription("Slaps user");

//Example of a trigger word for the bot
CommandManager.trigger(StartsWith("Ok"),triggers.okBoomer);

//Export the CommandManager you defined
module.exports=CommandManager;

Setting up the bot

const CommandManager=require("./CommandManager"); //The CommandManager defined in the Setting up commands section
const secret = require("./secret.json"); //Json file with token given by discord
const discord = require("discord.js");
const client = new discord.Client();

client.login(secret.token);

client.on("ready",()=>console.log("Online"));

client.on("message",msg=>CommandManager.handleMessage(msg, client));

Making your own middleware functions

//Creating your own middleware function
function(msg,client,params,next){
  var condition;//Your condition for the middleware to pass
  if(condition){
    next();
  }
}
