Overview/Description
Node.js is a server-side framework that uses an event driven asynchronous model and is built on the Google Chrome V8 JavaScript runtime engine. This course demonstrates how to work with events and processes to optimize Node.js applications. It also covers how to implement data security and authorization and authentication in Node.js applications.

Target Audience
Web developers who want to learn how to optimize and secure Node.js applications

Prerequisites
None

Expected Duration (hours)
2.7

Lesson Objectives

Optimizing and Securing Node.js Applications

start the course

describe EventEmitter and use it to create custom events in a Node application

describe the global process object and use it to access information about the current Node process

describe the Process object and implement it to handle events globally in a Node.js application

create child processes in Node.js applications using spawn

contrast spawn with exec and use exec to run shell commands as child processes in Node.js applications

contrast execFile with exec and spawn and use it to run a program file directly from a Node.js application

use fork to create child processes with inter-process communication in Node.js applications

use the Cluster module to cluster processes in a Node.js application

implement timers to control flow in a Node.js application

list and describe available hash algorithms in Node.js

use one or more hash algorithms to hash data in Node.js application

introduce the crypto module and use a cryptographic hash algorithm to check a file's integrity

use the bcryptjs module to secure user credentials

use the Node.js crypto module to encrypt user credentials

describe and use OpenSSL ciphers to encrypt data in Node.js

use the Node.js TLS module to secure server transmissions

set up a Mongo database and Jade views to support session-based authentication in Node.js Express applications

configure the passport module on top of an Express App to support user authentication from a Mongo database

implement local authentication in an Express App by defining the necessary routes and using passport

set up a Mongo database and Jade views to support authorization in a Node Express application

implement basic role-based authorization in an Express application

use HMAC to implement message authentication in Node.js applications

set up a Mongo database and Jade views to support token-based authentication in Node.js Express applications

configure the passport module on top of an Express App to support token-based user authentication

implement token-based authentication in an Express App by defining the necessary routes and using passport

understand concepts in optimizing and securing Node.js applications
