Sample Code: Basic Node.js Server

Below is a simple Node.js code sample to create a basic server. This example is basic and would be just a small part of an entire ERP system, but it gives an idea of how Node.js can be used to set up server-side functionality.

const express = require('express');
const app = express();

app.get('/', (req, res) => {
res.send('Hello, this is a basic Node.js server for an ERP system!');
});

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});

To run this code, you would need Node.js installed on your system and the Express.js framework, which can be installed using npm (Node Package Manager):

npm init -y
npm install express

This example is a starting point. Real-world ERP systems would involve more complex functionalities, including database interactions, authentication, real-time data processing, and integration with other business systems and services.

Code Sample

Let’s consider a scenario where we’re using Node.js to develop a part of an ERP system, specifically for handling real-time inventory updates. This example will demonstrate asynchronous I/O operations, real-time data processing, and integration with a database (using MongoDB for simplicity).

Prerequisites

• Node.js installed on your system
• MongoDB setup for database operations
• Install necessary Node.js packages: express for creating the server and mongoose for interacting with MongoDB

Sample Code

First, install the necessary packages using npm:

By leveraging these capabilities, Node.js can help create ERP systems that are not only efficient and scalable but also adaptable to the evolving needs of a business.

npm init -y
npm install express mongoose

Here’s a basic Node.js script:

const express = require('express');
const mongoose = require('mongoose');
const app = express();

// MongoDB connection string (replace with your own URI)
const mongoURI = 'mongodb://localhost:27017/erpInventory';

// Connect to MongoDB
mongoose.connect(mongoURI, { useNewUrlParser: true, useUnifiedTopology: true })
.then(() => console.log('MongoDB connected'))
.catch(err => console.error(err));

// Schema for Inventory Item
const inventorySchema = new mongoose.Schema({
itemName: String,
quantity: Number,
lastUpdated: { type: Date, default: Date.now }
});

// Model for Inventory
const InventoryItem = mongoose.model('InventoryItem', inventorySchema);

// Middleware to parse JSON
app.use(express.json());

// Route to get all inventory items
app.get('/inventory', async (req, res) => {
try {
const items = await InventoryItem.find();
res.json(items);
} catch (err) {
res.status(500).send(err);
}
});

// Route to update an inventory item
app.put('/inventory/update', async (req, res) => {
try {
const { itemName, quantity } = req.body;
const updatedItem = await InventoryItem.findOneAndUpdate(
{ itemName },
{ quantity, lastUpdated: Date.now() },
{ new: true }
);
res.json(updatedItem);
} catch (err) {
res.status(500).send(err);
}
});

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => console.log(`Server running on port ${PORT}`));

Explanation

• This script sets up a basic Express server and connects to a MongoDB database.
• It defines a schema and model for inventory items using Mongoose.
• There are two routes:
  • GET /inventory: Retrieves all inventory items.
  • PUT /inventory/update: Updates the quantity of a specific inventory item.
• The operations are asynchronous, utilizing async/await for handling database operations.

How to Run

1. Start your MongoDB server.
2. Run this script with Node.js.
3. Use a tool like Postman or a web browser to interact with the API.

app.put('/inventory/update', async (req, res) => {
const { itemName, quantity } = req.body;
// Update inventory logic (asynchronous)
res.send(`Inventory updated: ${itemName} - ${quantity}`);
});

app.listen(3000, () => console.log('Server running on port 3000'));

Python Example: Batch Data Processing

Python, with frameworks like Flask or Django, is often praised for its simplicity and readability, suitable for complex business logic.

# Python with Flask
from flask import Flask, request
app = Flask(__name__)

@app.route('/inventory/update', methods=['PUT'])
def update_inventory():
data = request.json
item_name = data['itemName']
quantity = data['quantity']
# Update inventory logic (synchronous)
return f'Inventory updated: {item_name} - {quantity}'

if __name__ == '__main__':
app.run(port=3000)

Java Example: Enterprise-Grade Solution

Java, often used in large-scale enterprise applications, excels in robustness and has a vast ecosystem of tools and libraries.

// Java with Spring Boot

public static void main(String[] args) {
SpringApplication.run(ErpApplication.class, args);
}
}

@RestController
class InventoryController {

@PutMapping("/inventory/update")
public String updateInventory(@RequestBody InventoryItem item) {
// Update inventory logic
return "Inventory updated: " + item.getItemName() + " - " + item.getQuantity();
}
}

class InventoryItem {
private String itemName;
private int quantity;
// Getters and setters...
}

Comparison:
