This document is intended for readers who know at least a little bit of a couple of things:

• a scripting language like JavaScript, Ruby, Python, Perl, etc. If you aren't a programmer yet then it is probably easier to start by reading JavaScript for Cats. 🐈
• git and github. These are the open source collaboration tools that people in the node community use to share modules. You just need to know the basics. Here are three great intro tutorials: 1, 2, 3

• Learn node interactively
• Understanding node
• Core modules
• Callbacks
• Events
• Streams
• Modules and npm
• Client side development with npm
• Going with the grain

In addition to reading this guide it's super important to also bust out your favorite text editor and actually write some node code. I always find that when I…

nodemon is a tool that helps develop Node.js based applications by automatically restarting the node application when file changes in the directory are detected.

nodemon does not require any additional changes to your code or method of development. nodemon is a replacement wrapper for node. To use nodemon, replace the word node on the command line when executing your script.

Either through cloning with git or by using npm (the recommended way):

npm install -g nodemon # or using yarn: yarn global add nodemon

And nodemon will be installed globally to your system path.

You can also install nodemon as a development dependency:

npm install --save-dev nodemon # or using yarn: yarn add nodemon -D

With a local installation, nodemon will not be available in your system path or you can't use it directly from the command line. Instead, the local installation of nodemon can be…

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Microsoft ❤️ Node.js!

We work hard to contribute to the Node.js community and we want to make sure your experience is as seamless as possible. In particular, our goals here are to:

• make it easier for people using Microsoft services and technologies to get started on the right foot with Node.js
• consolidate Microsoft's Node.js offerings in a centralized place to make it easier for you to find information
• communicate status on key issues we're addressing and collect feedback from the Node.js community on how we can do better.
• provide a forum to connect with various teams at Microsoft working on improving the Node.js experience.

Note that this is not intended to be a comprehensive set of recommendations. Rather it's meant to be a helpful set of content that makes it easier to avoid any potential gotchas, and the beginning of what we expect to be an…

From late 2012 to the present I have been writing backends (server-side code) for web applications. This document summarizes many aspects of how I write these pieces of code.

I'm writing this lore down for three purposes:

1. Share it with you.
2. Systematize it for future reference and improvement.
3. Learn from your feedback.

Your questions and observations are very welcome!

If you must sting, please also be nice. But above all, please be accurate.

I'd like to thank everyone who joined in the HN discussion of this document and pointed out or stimulated many interesting points that I had missed. I'm humbled and grateful for the tremendously positive and constructive feedback I received. Y'all rock.

This is all public domain; take whatever you find useful.

My approach to backends (as with code in general) is to iteratively strive for simplicity. This approach - and…
