Build Your Own Web Server From Scratch in Node.JS: Learn network programming, HTTP, and WebSocket by James Smith (Author

Learn by doing: code a Web server in Node.js

Most people use HTTP daily, but few understand its inner workings. This "Build Your Own X" book dives deep, teaching basics from scratch for a clearer understanding of the tools and tech we rely on.

• Network programming.
• Protocols & communication.
• HTTP in detail.
• WebSocket & concurrency.

The project uses Node.js and TypeScript without any dependencies, but many concepts are language-agnostic, so it’s valuable for learners of any language.

Beyond coding exercises

At the end of each chapter, there are discussions about:

• What’s missing from the code? The gap between toys and the real thing, such as optimizations and applications.
• Important concepts beyond coding, such as event loops and backpressure. These are what you are likely to overlook.
• Design choices. Why stuff has to work that way? You can learn from both the good ones and the bad ones.
• Alternative routes. Where you can deviate from this book.

Build your own X

Why take on a build-your-own-X challenge? A few scenarios to consider:

• Students: Solidify learning, build portfolio, stand out in future careers.
• Developers: Master fundamentals beyond frameworks and tools.
• Hobbyists: Explore interests with flexible, extensible projects.

This is part of the “Build Your Own X” book series, which includes books on building your own Redis, database, and compiler.
