## Setup Instructions
1. **Clone the Repository**
```sh
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:
```sh
npm install
```
3. **Setup Environment Variables**
Create a `.env` file in the root directory and add the following variables:
```plaintext
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:
```sh
npm run build
```
5. **Start the Server**
- For development:
```sh
npm run start:dev
```
- For production:
```sh
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:
```javascript
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:
```json
{
"semi": true,
"singleQuote": true,
"arrowParens": "avoid"
}
```
## Implementing the Application Code
#### app.ts
This file sets up the Express application, configures middleware, and defines routes.
```typescript
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.
```typescript
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.
```typescript
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`.
### Example Request Body
```json
{
"name": "Wireless Mouse",
"description": "Ergonomic wireless mouse with adjustable DPI settings.",
"price": 29.99,
"category": "Electronics",
"tags": ["computer", "peripherals", "wireless", "ergonomic"],
"variants": [
{ "type": "color", "value": "Black" },
{ "type": "color", "value": "White" }
],
"inventory": {
"quantity": 150,
"inStock": true
}
}
```
### Response
#### Success Response
- **Status Code:** `200 OK`
- **Content:** A JSON object containing the created product.
```json
{
"success": true,
"message": "Product created successfully!",
"data": {
"_id": "60c72b2f9b1d8b3c88b1e7a1",
"name": "Wireless Mouse",
"description": "Ergonomic wireless mouse with adjustable DPI settings.",
"price": 29.99,
"category": "Electronics",
"tags": ["computer", "peripherals", "wireless", "ergonomic"],
"variants": [
{ "type": "color", "value": "Black" },
{ "type": "color", "value": "White" }
],
"inventory": {
"quantity": 150,
"inStock": true
},
"isDeleted": false,
"__v": 0
}
}
```

- **Content:** A JSON object containing the error message.
```json
{
"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:
```typescript
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:
```typescript
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:
```typescript
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;
```

import { Request, Response } from 'express';
import services from './product.service';
import productValidation from './product.validation';
const updateProduct = async (req: Request, res: Response) => {
try {
const productId = { _id: req.params.productId };
const product = await productValidation.parseAsync(req.body);
await services.updateProductInDB(productId, product);
const updatedProduct = await services.getProductByIdFromDB(productId);
res.status(200).json({

```
PUT /api/products/{productId}
```
Replace `{productId}` with the actual ID of the product you want to update. The request body should contain the updated product details in JSON format.
## Delete a Product
This section demonstrates how to delete a product by marking it as deleted in the database using a DELETE request. The product is not actually removed from the database but is flagged as deleted.
### Endpoint
- **URL:** `/api/products/:productId`
- **Method:** `DELETE`
### Success Response
- **Status Code:** `200 OK`
- **Content:** Confirmation message.
```json
{

- **Content:** Error message.
```json
{
"success": false,
"message": "Request Could Not Complete",
"data": "Error details here"
}
```
### Implementation Details
#### Controller (`product.controller.ts`)
```typescript
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`)
```typescript
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.
```typescript
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({
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('products', productSchema);
```
#### Route (`product.route.ts`)
```typescript
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.
```typescript
// 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.
```typescript
// 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!',
data: result,
});
} catch (err: any) {
res.status(500).json({
success: false,
message: err.message || 'Request could not complete',
});
}
};
