مهارت‌های توسعه وب خود را از مرورگر به سمت سرور با Node.js ارتقا دهید—فریم‌ورک محبوب سمت سرور که بیش از ۱۰ میلیون توسعه‌دهنده در شرکت‌هایی مانند آمازون، نتفلیکس و لینکدین از آن استفاده می‌کنند. اگر با زبان JavaScript آشنایی دارید، این راهنمای کاربردی از Samer Buna به شما نشان می‌دهد چگونه حتی پیچیده‌ترین برنامه‌های Node.js را به‌طور مؤثر طراحی و نگهداری کنید.

با رویکردی پروژه‌محور و عملی، در این کتاب از مفاهیم پایه تا مباحث پیشرفته مانند ماژول‌ها، پکیج‌ها، معماری رویداد-محور، استریم‌ها، پردازش‌های فرزند، مقیاس‌پذیری، تست، استقرار و بسیاری موارد دیگر پیش می‌روید—همه با تمرکز بر نکاتی که در عمل اهمیت دارند.

Take your web development skills from browser to server with Node.js, the popular backend framework used by more than 10 million developers at companies like Amazon, Netflix, and LinkedIn, to name just a few. If you're comfortable working with JavaScript, this practical guide from Samer Buna will show you how to effectively build and maintain even the most complex Node.js applications.

Following a hands-on, project-based approach, you'll move from key fundamentals to advanced concepts such as modules, packages, event-driven architecture, streams, child processes, scaling, testing, deployment, and much more—all while focusing on what actually matters in practice.

• Understand Node.js's native capabilities in order to best use the powerful libraries and tools in its ecosystem
• Utilize Node.js modules and packages
• Explore Node.js's event-driven architecture, streams, and child processes
• Create, test, and maintain efficient and scalable Node.js applications

Who Should Read This Book

This book is my attempt at helping you learn Node.js efficiently. It naturally dips into a few JavaScript concepts, but in general, you need a good basic understanding of the JavaScript language to get the most value out of this book.

If you’re not comfortable working with JavaScript objects, functions, operators, and iterators, reading an introductory book about JavaScript before this book would help.

This is the book that I wished existed when I started learning Node.js. At that time, I was mainly focusing on the frontend. Naturally, this book is a good fit for a frontend developer wanting to expand their experience to the backend.

Why I Wrote This Book

When it comes to learning Node.js, many tutorials, books, and courses tend to focus on the libraries and tools available within the Node.js ecosystem, rather than the Node.js runtime environment itself. They prioritize teaching how to utilize popular Node.js libraries and frameworks, instead of starting from the native capabilities of Node.js.

This approach is understandable because Node.js is a low-level runtime environment. It does not offer comprehensive solutions but rather a collection of small essential modules that makes creating solutions easier and faster. For example, a full-fledged web server will have options like serving static files (like images, CSS files, etc.). With the Node.js built-in http module, you can build a web server that serves binary data, and with the Node.js built-in fs module, you can read the content of a file from the filesystem. You can combine both of these features to serve static assets by using your own JavaScript code. There’s no built-in Node.js way to serve static assets under a web server.

Popular Node.js libraries that are not part of Node.js itself (such as Express.js, Next.js, and many others with .js in their names) aim to provide nearly complete solutions within specific domains. For example, Express.js specializes in creating and running a web server (and serving static assets, and many other neat features). Practically, most developers will not be using Node.js on its own, so it makes sense for educational materials to focus on the libraries offering comprehensive solutions, so learners can skip to the good parts. The common thinking here is that only developers whose job is to write these libraries need to understand the underlying base layer of Node.js.

However, I would argue that a solid understanding of the built-in power of Node.js is essential before utilizing any of its external libraries and tools. Having a deep understanding of Node.js allows developers to make informed decisions when choosing which libraries to use and how to use them effectively. This book is my attempt to prioritize first learning the native capabilities of Node.js and then using that knowledge to efficiently utilize the powerful libraries and tools in its ecosystem.
