1 Introduction to Node.js

• What is Node.js?
• The tools: node and npm
• Node.js development environment
• Node.js architecture concepts: IO, asynchronous, non-blocking, concurrency, event-loop, scalability

Workshops:

• Installation of Node.js and a development environment
• Demonstration of the event loop through a first asynchronous / non-blocking program
• REPL

2 Events

• Node.js event-based architecture
• Event and EventEmitter
• Synchronous vs. Asynchronous
• Management of multiple or single events
• Error management

Workshops:

• Custom EventEmitter development

3 Streams

• Examples of streaming data managed by Node.js
• The different types of Streams
• Internal buffers
• Pipelines

Workshops:

• Consume a Readable stream (http, fs)
• Writing in a Writable (fs) stream
• Exploiting a Duplex stream (net.Socket)
• Use a Transform stream (zlib)

4 Error handling

• The different types of errors
• Error handling in synchronous APIs
• Error handling in asynchronous APIs
• Assertions
• Logging via the Console API
• Debugging a Node.js program

Workshops:

• Error handling in synchronous APIs
• Error handling in asynchronous APIs
• Debug a Node.js program in its IDE or in Chrome

5 Modularity

• Global Object and inter-module scope
• Globally accessible objects
• Modules, scopes and file management
• Core modules
• Main module
• Module loading algorithm and module cache
• NPM and third-party modules

Workshops:

• Using the Global object
• Globally accessible objects: process
• Use of core modules: timer, OS, Util, Path,…
• Internal module creation for the application
• Creation of a Node.js project via NPM and installation of popular modules

6 TCP/UDP Servers/Clients

• Net module for creating TCP servers and clients
• UDP/Datagram module for creating UDP/Datagram servers and clients

Workshops:

• Creation of TCP server/clients
• Creation of UDP/Datagram server/clients

7 Http, https and http/2 servers and clients

• Http, https and http/2 modules for creating http, https and http/2 servers and clients
• Url module to process http requests

Workshops:

• Creation of http, https and http/2 servers and clients as part of a website
• Creation of http, https and http/2 servers and clients as part of a RESTFul webservice

8 File system interactions

• The fs module and its closeness to POSIX
• Synchronous APIs vs Asynchronous APIs

Workshops:

• File system interactions via synchronous and asynchronous APIs

9 Web back-end development

• Data management with Relational databases (Mysql) or NoSQL (Mongo, Redis)
• Middleware management (connect, expressjs)
• Template management (ejs)

Workshops:

• Creation of a static and dynamic web backend with express.js
• Creation of a RESTFul API with express.js

10 Deploy a Node.js application

• NPM: the main commands
• NPM: packaging a module
• Different ways of deploying a Node.js project
• Forever and PM2 modules

Workshops:

• Package a library
