1. About Node.js

The capabilities of Node.js

Server-side JavaScript

Why should you use Node.js?

Popularity JavaScript at all levels of the stack Leveraging Google's investment in V8 Leaner asynchronous event-driven model Microservice architecture The Node.js is stronger for having survived a major schism and hostile fork Performance and utilization Is Node.js a cancerous scalability disaster? Server utilization, the bottom line, and green web hosting Node.js, the microservice architecture, and easily testable systems Node.js and the Twelve-Factor app model

Summary

2. Setting up Node.js

System requirements Installing Node.js using package managers

Installing on Mac OS X with MacPorts Installing on Mac OS X with Homebrew Installing on Linux, *BSD, or Windows from package management systems Installing the Node.js distribution from nodejs.org

Installing from source on POSIX-like systems

Installing prerequisites Native code modules and node-gyp

Installing developer tools on Mac OS X

Installing from source for all POSIX-like systems Installing development instances with nvm

Node.js versions policy and what to use Running and testing commands

Node.js's command-line tools Running a simple script with Node.js Launching a server with Node.js

NPM – the Node.js package manager Node.js and ECMAScript 6 (ES-2015, ES-2016, and so on)

Using Babel to use experimental JavaScript features

Summary

3. Node.js Modules

Defining a module

Node.js module format File modules

A quick note about CommonJS Summary

4. HTTP Servers and Clients – A Web Application's First Steps

Sending and receiving events with EventEmitters

The EventEmitter theory

HTTP server applications ES-2015 multiline and template strings HTTP Sniffer – listening to the HTTP conversation Web application frameworks Getting started with Express

Walking through the default Express application The Express middleware Middleware and request paths Error handling

Calculating the Fibonacci sequence with an Express application

Computationally intensive code and the Node.js event loop

Algorithmic refactoring

Making HTTP Client requests Calling a REST backend service from an Express application

Summary

5. Your First Express Application

ES-2015 Promises and Express router functions

Promises and error handling Flattening our asynchronous code Additional tools

Express and the MVC paradigm Creating the Notes application

Your first Notes model The Notes home page Adding a new note – create Viewing notes – read Editing an existing note – update Deleting notes – destroy

Theming your Express application Scaling up – running multiple Notes instances Summary

6. Implementing the Mobile-First Paradigm

Problem – the Notes app isn't mobile friendly Mobile-first paradigm Using Twitter Bootstrap on the Notes application

Setting it up Adding Bootstrap to application templates

Mobile-first design for the Notes application

Summary

8. Multiuser Authentication the Microservice Way

Creating a user information microservice

User information model A REST server for user information Scripts to test and administer the User Authentication server Login support for the Notes application

Accessing the user authentication REST API Login and logout routing functions Login/logout changes to app.js Login/logout changes in routes/index.js Login/logout changes required in routes/notes.js View template changes supporting login/logout Running the Notes application with user authentication
