Node.js (often referred to as NodeJS or just Node) is a JavaScript runtime built on Chrome's V8 JavaScript engine.
It allows developers to run JavaScript on the server side while creating server-side applications using JavaScript.

It is an open-source, cross-platform runtime environment widely used to create scalable network applications.

Ryan Dahl wrote Node.js in 2009 in C++, with the initial release supporting only Linux and Mac OS X.
Its development and maintenance were led by Dahl and later sponsored by Joyent.

Primarily, developers use Node.js for backend development, but it is also popular for full-stack and even frontend solutions.
Developers commonly use Node.js for the following purposes:

Common Uses of Node.js:

  • Building web servers and APIs:
    Node.js is ideal for building lightweight, high-performance web servers and APIs. Its non-blocking I/O model is well-suited for handling many concurrent connections.

  • Real-time web applications:
    Developers use Node.js to build real-time applications that require low latency and fast data transfer, such as chat apps and online games.

  • Command-line tools:
    Node.js is used to create command-line tools and utilities. Its package manager (NPM) makes it easy to find and use thousands of existing packages.

  • Building and automating build processes:
    Developers leverage Node.js as a build tool to automate tasks like minifying code, compiling assets, and running tests.

  • Microservices:
    Node.js is increasingly adopted for building microservices — small, independent services that can be developed, deployed, and scaled independently.

Node.js is a very popular choice even among major tech companies.
Brands like Microsoft, Netflix, Uber, PayPal, NASA, eBay, Amazon Web Services (AWS), and others use Node.js to power parts of their businesses.

If you are hiring a Node.js developer, look for a few essential factors regarding their knowledge and skills.

The essential skills a Node.js developer should have include:

  • Proficiency in JavaScript/TypeScript

  • Understanding of functional programming concepts (e.g., higher-order functions)

  • Knowledge of dependency injection, MVC patterns, and design patterns

  • Familiarity with standard development tools like Git, ESLint, and Prettier

  • Practical understanding of SQL

  • Experience with Docker and Docker Compose

  • Hands-on expertise in Node.js itself

Node.js Developer Experience Levels:

  • Entry-level/Junior Node.js Developer (0–2 years of experience):
    A developer relatively new to Node.js, with basic knowledge of the language and frameworks.
    They typically need guidance and support, may not complete tasks independently, but can contribute as part of larger projects.

  • Intermediate Node.js Developer (2–5 years of experience):
    A developer with a solid understanding of Node.js and its ecosystem, able to build and maintain scalable, production-grade applications.
    They can usually complete most tasks with minimal guidance and may lead small development teams.

  • Senior Node.js Developer (5+ years of experience):
    A Node.js expert with extensive experience building and maintaining scalable, production-grade systems.
    They have likely led large development teams and worked across multiple platforms.
    Senior Node.js developers often have full-stack experience with MERN (MongoDB, Express, React, Node) or MEAN (MongoDB, Express, Angular, Node) stacks.

Suggested Hiring Process for a Node.js Developer:

  1. Resume and Cover Letter Review
    Identify candidates who meet the position’s qualifications and experience requirements.

  2. Reference and Background Checks
    Verify the candidate’s credentials and previous experience.

  3. Initial Interview
    Conduct an in-person or video interview covering their background, experience, and understanding of Node.js and related technologies.

  4. Technical Assessment
    Assign a coding challenge or take-home project to evaluate the candidate’s technical and problem-solving skills.

  5. On-site or Remote Final Interview
    Conduct a session that includes technical and behavioral questions, potentially with a pair-programming exercise.

  6. Job Offer
    Extend an offer to the candidate who best fits the company’s needs and culture.

The specific steps may vary by company and role, but the goal is to thoroughly assess technical skills, Node.js experience, and cultural fit.

Responsibilities:

  • Developing the latest backend features using JavaScript/TypeScript, Node.js, and Nest.js

  • Suggest improvements and present them to the client and the team

  • Optimizing components for maximum performance across a vast array of web-capable devices and browsers

  • Following industry and tech standards

  • Writing effective APIs

  • Troubleshooting, debugging, and upgrading the codebase

Education & Experience:

  • Bachelor’s degree in Computer Science/related field or equivalent experience

  • Excellent verbal and written English skills

  • High proficiency with and experience in Node.js

  • Experience with HTML, CSS, and JavaScript

  • Front-end and back-end development experience

When seeking to hire a Node.js developer, here are a few good questions to ask in a technical interview:

Question 1: What is an error-first callback in Node.js?

An error-first callback is a function used to pass both errors and data. It follows the convention of taking an error object as its first argument—if there’s no error, that argument is null.

Question 2: Explain what buffers are in Node.js and what they are used for.

Buffers in Node.js are a way to handle binary data in JavaScript. They:

  • Act as temporary memory used by streams to hold data until it’s consumed.

  • Resemble integer arrays but map to raw memory outside of the JS heap.

  • Represent fixed-size chunks of memory that cannot be resized.

  • Support legacy encodings like ASCII and UTF-8.

Question 3: Provide an example of utilizing async/await in Node.js.

Here’s a simple async/await pattern example:

Question 4: Explain how the workflow looks in Node.js.

  1. Client request → sent to the web server (could be non-blocking or blocking).

  2. Event Queue → Node.js pushes incoming requests here.

  3. Event Loop →

    • Processes simple, non-blocking operations (I/O polling) and returns responses.

    • For complex, blocking operations, delegates to a Thread Pool thread.

  4. Thread Pool → handles blocking tasks (e.g., database, file system). When done, returns the result back to the Event Loop, which then responds to the client.

This non-blocking, event-driven model lets Node.js handle many concurrent connections efficiently—ideal for real-time apps, chat services, and high-throughput APIs.

Question 5: What is “callback hell,” and how can you avoid it?

“Callback hell” describes deeply nested callbacks that become hard to read and maintain. Common ways to avoid it:

  • Modularization: Break nested callbacks into smaller, named functions.

  • Promises: Flatten chains by returning promises instead of nesting callbacks.

  • Async/Await: Make asynchronous code read like synchronous logic.

  • Generators (less common for simple cases): Manage flow control more cleanly.
