Duzzle Library

This library provides a utility for managing MongoDB schemas and interacting with them using a clean and structured interface. It includes two core classes: Shape , App and Server , each extending the EventEmitter class for event-driven programming. The package allows you to dynamically define schemas using the createShape function, with the schema data being directly represented by the Shape class and you can make a server app and manag it easy.

Installation

Install the package using npm:

bun add duzzle
npm install duzzle

Usage

Setting up the App Class

The App class handles the database connection and manages different Shape instances.

import { App } from 'duzzle';

// Create a new instance of App
const app = new App('mongodb://localhost:27017/mydatabase');

// Connect to the database
app.connect().then(() => {
    console.log('Connected to the database!');
}).catch(err => {
    console.error('Failed to connect to the database:', err);
});

// Disconnect when done
app.disconnect().then(() => {
    console.log('Disconnected from the database!');
});

Dynamically Creating Shapes with App

The createShape function allows you to dynamically define schemas and manage them through Shape instances.

import { ShapeAdd } from 'duzzle';

const shapeOptions: ShapeAdd = {
    name: 'Product',
    SchemaData: {
        title: String,
        price: Number,
        products: [{name: String, price: Number}]
    }
};

const shape = await app.createShape(shapeOptions)

    shape.searchWI({ key: 'title', value: 'Laptop', type: 1 }).then(result => {
        console.log('Product search results:', result);
    });

     shape.searchWI({ key: 'products.name', value: 'Laptop', type: 1 }).then(result => {
        console.log('Product search results:', result);
    });

Create A HTTP Server

the start function it stats a server with port you provided in parametar

import { Server } from "duzzle"

const app = new Server(300* /* Server Port */)


// Strat the http server

 app.start()
    .then(() => console.log('Server started on port 3000'))
    .catch((r) => console.error)

 // server with security options:

 app.start({
    enableRateLimit: true, enableHelmet: true,
    cors: {
        enable: true,
        origin: "http://localhost:3000",
        methods: ["GET", "POST", "PUT", "DELETE"],
        jsonLimit: "500kb",       
        urlencoded: "500mb",
        allowdHeaders: ["Content-Type"], 
    }
})
    .then(() => console.log('Server started on port 3000'))
    .catch((r) => console.error)

// [get, delete, put, patch, post...]
    app.get("/hello", [/*middlewares if no put it empty arr*/], {
        run: (req, res) => {
            res.send("hello world")
        }
    })

    // create a route
    const Route = app.Route()
    
    Route.get("/", (req, res) => res.send("hi"))

    app.useRouter("/main", Route)

Connect To Duzzle Db Using HTTP Server

let db = await app.connectDb("mongourl")

// Security Options

let db = await app.connectDb("mongourl", {
    autoHash: {
        enable: true,
        words: ["password"]
    }
})

Create Shape In HTTPS Server

    const UserShape = await db.createShape({
        name: "users", SchemaData: {
            name: String,
            dash: String,
            password: String
        }
    }) 

// Insert Function

await UserShape.model.insertMany(...[
    {name: "ahmed", products: [{name:"mouse", price:15}] /* Document */}, {name: "amr" , products: [{name:"mouse", price:15}]}
    ])


    // Edit With Item
   

 const S = await UserShape.editWI({ key: "name", value: "amr" }, { key: "products.name", value: "keyboard" }, 1)
