Intro to OAuth with Node.js: OAuth 1.0 (One-Legged)

This text is part of Introduction to OAuth with Node.js mini-book which is available at gum.co/hRyc.

Let’s start with good old OAuth 1.0. The way it usually works is as follows:

For the first time, when we authorize a user to use our app, we need to perform extra work and obtain access token and secret (three-legged).
You store these values for each user in your application.
Then, on subsequent requests, things become much simpler. We construct auth headers and make HTTP requests (one-legged).

Seven Things You Should Stop Doing with Node.js

Inspired by 5 Things You Should Stop Doing With jQuery by Burke Holland, I decided to open a discussion and highlight seven things you should immediately stop doing with Node.js:

Stop using callbacks
Stop using * for versions
Stop using console.log for debugging
Stop using GET and POST for everything
Stop using semicolons
Stop using comma-first style
Stop limiting your connections with default maxSockets value

Node.js FUNdamentals: A Concise Overview of The Main Concepts

Node.js is a highly efficient and scalable non-blocking I/O platform that was build on top of Google Chrome V8 engine and its ECMAScript. This means that most front-end JavaScript (another implementation of ECMAScript) objects, functions and methods are available in Node.js. Please refer to JavaScript FUNdamentals if you need a refresher on JS-specific basics.

Note: This text is a part of upcoming ebook JavaScript and Node FUNdamentals: A Collection of Essential Basics.

Express.js FUNdamentals: An Essential Overview of Express.js

Note: This text is a part of upcoming ebook JavaScript and Node FUNdamentals: A Collection of Essential Basics.

Express.js is an amazing framework for Node.js projects and used in the majority of such web apps. Unfortunately, there’s a lack of tutorials and examples on how to write good production-ready code. To mitigate this need, we released Express.js Guide: The Comprehesive Book on Express.js. However, all things start from basics, and for that reason we’ll give you a taste of the framework in this post, so you can decide if you want to continue the learning further.

Q&A: Thank You Web App, Express.js and Emails

I recently received a question from Joanne Daudier. She is a up and coming web developer, middle term student at a JS/Node.js bootcamp called RefactorU and a reader of Express.js Guide. This is what she wrote:

Hi Azat:

I skimmed over your book today. I feel like it is a bit advanced for me since I’m just learning Express. I do have a few questions for you though.

Solving Programming Problems

Programming problems are not that much different from mathematics or physics problems. There are usually an input and an output to which someone needs to arrive by providing an algorithm. This algorithm is typically a function or series of functions.

Programming puzzles and toy problems are good exercises to sharpen skills and prepare for technical interviews. No wonder that more and more online coding schools (e.g., CodeAcademy) make those metal workouts main staple of their courses.

Beginner programmers might benefit by applying these steps to their process of solving a programming problem:

The Release of Express.js Guide: The Comprehensive Book on Express.js

After weeks of writing and editing, Azat and his team are happy to announce the release of Express.js Guide: The Most Popular Node.js Framework Manual! The book is very approachable and suitable for beginners. If someone wants to save time searching the web and learn the best practices from the trenches, Express.js Guide is the book that has everything: Express.js API reference, quick start guides, 20+ meticulously explained examples and tutorials on over 270 pages with more than 60 illustrations.

Express.js is a de facto standard of Node.js development and the most popular NPM library as of today! However, as with any framework, sometimes the learning curve is steep. At HackReactor, I often asked the same questions about code organization, authentication, database connections and deployment.

PHP vs. Node.js

TL;DR: PHP is not going to disappear immediately, but its positions are undermined even further by the nascent Node.js.

When the Internet exploded in the 2000s, PHP was a thing all the cool kids did. It was extremely revolutionary, because:

It was an interpreted language unlike C++ or Java which require the source code compilation
It had the ability to be used directly with HTML by mixing within its template files with a <%php ... %> markup tags
It had cheap shared hosting providers on Apache servers with a Linux, Apache, MySQL and PHP (LAMP) stack
It had a functional nature which is easier to learn than the object-oriented programming

Over the years, PHP and its apps became a monstrous technology vulnerable to security threats (e.g., SQL injections), lack of a centralized packaging registry (was Composer inspired by Node Package Manager?), inconsistent API and subpar performance. There are many better alternatives to PHP, e.g., Ruby on Rails and Django, however nothing is as approachable as Node.js.

For those of you who aren’t familiar with Node.js, or who have heard of it but can’t quite grasp the concept, here is my analogy:

Node.js is functionally similar to the PHP + Apache or ASP + IIS stacks.

Nowadays, Node.js is gaining momentum. The platform uses JavaScript. It’s functional, and its non-blocking I/O mechanism allows for a better performance. Node.js comes with a robust Node Package Manager solution and the specification, i.e., ECMAScript.

Because Node.js is a lower-level technology, it is not comparable to complex frameworks like Struts, Rails or Django directly.

Therefore, many people, whether software engineers or entrepreneurs, are often faced with the decision of “What tech stack to use” In this article PHP vs. Node.js, we’ll compare apples-to-apples approaching the question from different angles, such as:

Syntax
Context switch
Modules
Ecosystem
Frameworks
Real-time apps
Database apps
Third-party services apps
Web servers
Hosting
Performance

Web Frameworks for Node.js

Note: For a detailed Express.js learning resource, please check out Express.js Guide: The Most Popular Node.js Framework Manual book.

TL;DR Visit nodeframework.com.

Node.js is one of the fastest growing platforms, but its’s relatively young. Therefore, there’s no dominant framework like Django for Python, Rails for Ruby or Cake for PHP. Node.js frameworks niche is level playing field.

There are multiple libraries and philosophies including MVC concept, configuration over convention, applying principles from Ruby on Rails, and the approach of merging front-end and back-end. It becomes more tedious for developers to make an educated right choice. Because of it, we put together a resource called nodeframework.com (also nodeframeworks.com and mvcnode.com, which one you like the best?) which serves as a hand-picked registry of web frameworks for Node.js. It’s an open-source project so please feel free to contribute examples, descriptions or awesome new Node.js frameworks!

Cisco, Node.js and other musings

The hands-on Introduction to Node.js training consisted of two days and started badly: I was late driving from Oakland to San Jose through traffic, and security personnel in the lobby took extra 15 minutes to clear and escort me to the classroom. Nevertheless, attendees quickly plunged into installing Node.js, Node Package Manager and MongoDB using hard copies of Rapid Prototyping with JS: Agile JavaScript Development that I brought with me.
