LONG ISLAND SOFTWARE DEVELOPMENT

Node.js Programming for Long Island and New York

Custom Node.js applications, APIs, data integration and server-side JavaScript. Net/Works Computer Consulting builds software that connects devices, cloud services, databases and business systems.

We develop complete applications as well as smaller integrations and automation tools. Our work includes MySQL, MongoDB, and cloud-based Linux servers.

Real project: vehicle telemetry into MongoDB

For one client, we developed a Node.js API to receive cellular data sent by a device in a moving vehicle. The device transmitted its readings to an endpoint at a specified IP address. We configured an AWS Linux cloud server, installed Node.js, adapted the JavaScript application to parse incoming data, and stored the results in MongoDB.

What we build with Node.js

JavaScript beyond the browser

Node.js runs JavaScript on servers and other systems, not just in a web page. It is free, open source, and available for Linux and Windows. Visit the official Node.js website for more information.

Example: a small Node.js API

The original page included a longer introductory Express/MySQL tutorial. The example below is a shorter, updated illustration of the same idea: retrieving a database record through an HTTP endpoint. It uses environment variables for credentials and a parameterized SQL query. It is illustrative, not a complete production application.

// Illustrative Express + MySQL API (not a production-ready app)
const express = require('express');
const mysql = require('mysql2/promise');
const app = express();
app.use(express.json());

const pool = mysql.createPool({
  host: process.env.DB_HOST || 'localhost',
  user: process.env.DB_USER,
  password: process.env.DB_PASSWORD,
  database: process.env.DB_NAME
});

app.get('/api/posts/:id', async (req, res) => {
  const id = Number(req.params.id);
  if (!Number.isSafeInteger(id) || id < 1) {
    return res.status(400).json({ error: 'Invalid ID' });
  }
  try {
    const [rows] = await pool.execute(
      'SELECT id, title, body FROM posts WHERE id = ?', [id]
    );
    if (!rows.length) return res.sendStatus(404);
    res.json(rows[0]);
  } catch (err) {
    console.error(err);
    res.status(500).json({ error: 'Database error' });
  }
});

app.listen(3000, () => console.log('API listening on port 3000'));

The original example demonstrated creating tables, inserting records, querying, updating and deleting. In a real application, we would add authentication, access controls, input validation and deployment safeguards appropriate to the project.
