Setup Instructions

1. Clone the Repository

   git clone https://github.com/Muslehud77/deep-dive-mongoose.git
   cd deep-dive-mongoose

2. Install Dependencies

   Make sure you have Node.js and npm installed. Then run:

   npm install

3. Setup Environment Variables

   Create a .env file in the root directory and add the following variables:

   PORT=your_port_number
   DB_URI=your_mongodb_connection_string
   

   Replace your_port_number with the port number you want the server to run on (e.g., 6000) and your_mongodb_connection_string with your actual MongoDB connection string.

4. Build the Project

   Compile the TypeScript code to JavaScript:

   npm run build

5. Start the Server

   • For development:

     npm run start:dev

   • For production:

     npm run start:prod

Scripts

• build: Compiles TypeScript files to JavaScript.
• lint: Runs ESLint to analyze the code for potential errors and code style issues.
• lint:fix: Automatically fixes linting issues.
• prettier: Formats the code using Prettier.
• prettier:fix: Automatically formats the code using Prettier.
• start:dev: Starts the server in development mode with auto-reloading.
• start:prod: Starts the server in production mode.
• test: Placeholder for running tests.

Environment Variables

The following environment variables are used in the project:

• PORT: The port on which the server will run.
• DB_URI: The MongoDB connection string.

Make sure to replace the placeholder values in the .env file with your own configurations.

Certainly! Below is a detailed README section demonstrating how to create a product in your application.

Code Quality Configuration

ESLint and Prettier Setup

This project uses ESLint and Prettier to maintain code quality and consistency. Below are the configurations used for both tools.

ESLint Configuration

The ESLint configuration is set up to enforce a set of rules and integrates with Prettier for code formatting. Here is the .eslintrc.mjs configuration file:

import globals from 'globals';
import pluginJs from '@eslint/js';
import tseslint from 'typescript-eslint';

export default [
  {
    ignores: ['**/node_modules/', '.dist/'],
    languageOptions: {
      globals: {
        ...globals.browser,
        process: 'readonly',
      },
    },

    rules: {
      'no-unused-vars': 'error',
      'no-unused-expressions': 'error',
      'prefer-const': 'error',
      'no-console': 'warn',
      'no-undef': 'error',
      'prettier/prettier': 'error',
    },
  },

  pluginJs.configs.recommended,
  ...tseslint.configs.recommended,
  'prettier',
];

Prettier Configuration

The Prettier configuration is used to format code consistently across the project. Here is the .prettierrc.json configuration file:

{
  "semi": true,
  "singleQuote": true, 
  "arrowParens": "avoid"
}

Implementing the Application Code

app.ts

This file sets up the Express application, configures middleware, and defines routes.

import express, { Request, Response } from 'express';
import cors from 'cors';
import { productRoutes } from './models/product/product.route';
import { orderRoutes } from './models/Order/order.route';

const app = express();

// Parsers
app.use(express.json());
app.use(cors());

// Handling routes
app.use('/api/products', productRoutes);
app.use('/api/orders', orderRoutes);

app.get('/', (req: Request, res: Response) => {
  res.send('Hello World!');
});

app.use('*', (req: Request, res: Response) => {
  res.status(404).json({
    success: false,
    message: 'Route not found',
  });
});

export default app;

server.ts

This file starts the server and connects to the MongoDB database.

import app from './app';
import config from './configs';
import { connect } from 'mongoose';

async function run() {
  try {
    await connect(config.dbUri);
    app.listen(config.port, () => {
      console.log(`Server is listening on port ${config.port}`);
    });
  } catch (err) {
    console.error('Error connecting to the database', err);
  }
}

run();

index.ts in Configs

This file loads environment variables and exports the configuration.

import dotenv from 'dotenv';

dotenv.config();

const port = process.env.PORT;
const dbUri = process.env.DB_URI as string;

export default { port, dbUri };

Creating a Product

This section demonstrates how to create a product in your application using a POST request.

Endpoint

URL: /api/products

Method: POST

Request Body

The request body should be a JSON object containing the following fields:

• name (string): The name of the product. This field is required and must be unique.
• description (string): A description of the product. This field is required.
• price (number): The price of the product. This field is required.
• category (string): The category of the product. This field is required.
• tags (array of strings): A list of tags associated with the product. This field is required.
• variants (array of objects): A list of variants for the product. Each variant object should contain:
  • type (string): The type of the variant (e.g., color). This field is required.
  • value (string): The value of the variant (e.g., Black). This field is required.
• inventory (object): An object representing the inventory of the product. This field should contain:
  • quantity (number): The quantity of the product in stock. This field is required.
  • inStock (boolean): Whether the product is in stock. This field is required.
• isDeleted (boolean): Whether the product is deleted. This field is optional and defaults to false.

• Content: A JSON object containing the error message.

{
  "success": false,
  "message": "Request Could Not Complete",
  "data": "Error details here"
}

Implementation Details

Controller (product.controller.ts)

The addProduct function in the controller handles the logic for creating a new product:

import { Request, Response } from 'express';
import services from './product.service';
import productValidation from './product.validation';

const addProduct = async function (req: Request, res: Response) {
  try {
    const product = await productValidation.parseAsync(req.body);

    const result = await services.addProductIntoDB(product);

    res.status(200).json({
      success: true,
      message: 'Product created successfully!',
      data: result,
    });
  } catch (err) {
    res.status(500).json({
      success: false,
      message: 'Request Could Not Complete',
      data: err,
    });
  }
};

export default {
  addProduct,
  // other controller methods...
};

Service (product.service.ts)

The addProductIntoDB function in the service handles the database interaction:

import { TProduct } from './product.interface';
import { productModel } from './product.model';

const addProductIntoDB = async (product: TProduct) => {
  const result = await productModel.create(product);
  return result;
};

export default {
  addProductIntoDB,
  // other service methods...
};

Validation (product.validation.ts)

The productValidation schema ensures the request body is valid:

import { z } from 'zod';

const productValidation = z.object({
  name: z.string().min(1, { message: 'Name is required' }),
  description: z.string().min(1, { message: 'Description is required' }),
  price: z.number().positive({ message: 'Price must be a positive number' }),
  category: z.string().min(1, { message: 'Category is required' }),
  tags: z.array(z.string()).min(1, { message: 'At least one tag is required' }),
  variants: z.array(
    z.object({
      type: z.string().min(1, { message: 'Variant type is required' }),
      value: z.string().min(1, { message: 'Variant value is required' }),
    })
  ).min(1, { message: 'At least one variant is required' }),
  inventory: z.object({
    quantity: z.number().nonnegative({ message: 'Quantity must be a non-negative number' }),
    inStock: z.boolean(),
  }),
  isDeleted: z.boolean().default(false),
});

export default productValidation;

}

Error Response

• Status Code: 500 Internal Server Error
• Content: Error message.

{
  "success": false,
  "message": "Request Could Not Complete",
  "data": "Error details here"
}

Implementation Details

Controller (product.controller.ts)

import { Request, Response } from 'express';
import services from './product.service';

const deleteProduct = async (req: Request, res: Response) => {
  try {
    const productId = { _id: req.params.productId };

    await services.deleteProductFromDB(productId);

    res.status(200).json({
      success: true,
      message: 'Product deleted successfully!',
      data: null,
    });
  } catch (err) {
    res.status(500).json({
      success: false,
      message: 'Request Could Not Complete',
      data: err,
    });
  }
};

export default { deleteProduct };

Service (product.service.ts)

import { productModel } from './product.model';
import { TProduct } from './product.interface';

const deleteProductFromDB = async (id: { _id: string }) => {
  return await productModel.findByIdAndUpdate(id, { isDeleted: true });
};

export default { deleteProductFromDB };

Model (product.model.ts)

Ensure the schema includes the isDeleted field and middleware to exclude deleted records from queries.

import { Schema, model } from 'mongoose';
import { TProduct } from './product.interface';

const isRequiredString = { type: String, required: true };
const variantSchema = new Schema({
  type: isRequiredString,
  value: isRequiredString,
});

const productSchema = new Schema<TProduct>({
  name: { ...isRequiredString, unique: true },
  description: isRequiredString,
  price: { type: Number, required: true },
  category: isRequiredString,
  tags: { type: [String], required: true },
  variants: {
    type: [variantSchema],
    required: true,
  },
  inventory: { quantity: Number, inStock: Boolean },
  isDeleted: { type: Boolean, default: false },
});

productSchema.pre('find', function (next) {
  this.find({ isDeleted: { $ne: true } });
  next();
});

productSchema.pre('findOne', function (next) {
  this.find({ isDeleted: { $ne: true } });
  next();
});

export const productModel = model<TProduct>('products', productSchema);

Route (product.route.ts)

import express from 'express';
import productController from './product.controller';
const route = express.Router();

route.delete('/:productId', productController.deleteProduct);

export const productRoutes = route;

Example Usage

To delete a product, send a DELETE request to:

DELETE /api/products/{productId}

Replace {productId} with the actual ID of the product you want to delete. This will mark the product as deleted in the database without physically removing the record.

Certainly! Here's a structured guide for your README.md:

---

Create a New Order

To create a new order, the system checks if the product is in stock and updates the stock accordingly.

// order.controller.ts
import { Request, Response } from 'express';
import orderValidation from './order.validation';
import services from './order.service';

const addOrders = async function (req: Request, res: Response) {
  try {
    const order = await orderValidation.parseAsync(req.body);
    const result = await services.addOrdersToDB(order);
    res.status(200).json({
      success: true,
      message: 'Order created successfully!',
      data: result,
    });
  } catch (err: any) {
    res.status(500).json({
      success: false,
      message: err.message || 'Request could not complete',
    });
  }
};
export default addOrders;

Retrieve All Orders

This section retrieves all orders from the database.

// order.controller.ts
import { Request, Response } from 'express';
import services from './order.service';

const getAllOrders = async function (req: Request, res: Response) {
  try {
    const result = await services.getAllOrdersFromDB();
    if (!result.length) {
      throw new Error('Order not found');
    }
    res.status(200).json({
      success: true,
      message: 'Orders fetched successfully!',
