Node.js Guides by Arivu

• Node.js Enterprise Backend Guide — Scalable backend systems, APIs, and event-driven architecture using Node.js.
• Modern Node.js in 2026: Built-in Test Runner, Watch Mode, and Native TypeScript — The modern Node.js toolkit in 2026 — the built-in test runner, native watch mode, direct TypeScript execution, the standard fetch, and the env-file flag that replace old dependencies.
• Node.js Advanced: Enterprise API Design, Error Handling, and Production Architecture — Advanced Node.js patterns for enterprise systems — layered architecture, structured error handling, middleware design, async patterns at scale, and production-grade API engineering.
• Async Node.js: Callbacks, Promises, and async/await — Master asynchronous JavaScript in Node — from callback hell to promises and async/await, plus parallelism with Promise.all and common pitfalls.
• Complete Enterprise Next.js CSP Implementation Guide — Deep enterprise guide explaining Content Security Policy (CSP) implementation in Next.js applications including security architecture, nonce handling, unsafe patterns, SSR challenges, third-party scripts, middleware integration, and production hardening.
• Robust Error Handling in Node.js — Build resilient Node apps — operational vs. programmer errors, try/catch with async/await, error-handling middleware, and gracefully handling uncaught failures.
• Building REST APIs with Express.js — Build a clean REST API in Express — routing, middleware, request/response handling, route parameters, and structuring an app you can grow.
• Getting Started with Node.js: Runtime, Modules, and Your First Server — A clear introduction to Node.js — what the runtime is, the event loop in plain terms, CommonJS vs. ES modules, and building your first HTTP server.
• Node.js for Beginners: How It Works and When to Use It — A clear, practical introduction to Node.js — the event loop, async patterns, building your first API, and understanding when Node.js is the right tool.
• Understanding npm, package.json, and Dependency Management — Demystify the Node.js ecosystem — npm, package.json, semantic versioning, lockfiles, dependencies vs. devDependencies, and avoiding dependency pitfalls.
• Scaling Node.js: Cluster, Worker Threads, and Load Balancing — Push Node beyond a single core — the cluster module, worker threads for CPU-bound work, horizontal scaling, and avoiding event-loop blocking.
• Node.js Security Best Practices — Harden your Node apps — input validation, dependency hygiene, secrets management, secure headers, and defending against injection and common web attacks.
