TRAINING COURSE OVERVIEW

This is an intensive hands-on training course aimed at seasoned Node developers

The purpose of the course is to instil a deeper understanding of the language and best practices so as to allow delegates to feel confident that they are developing applications efficiently and optimally, using appropriate language, techniques, tools and test techniques.

Delegates will be introduced to theory and spend most of the time practicing the theory using specially developerd hands-on Labs.

AUDIENCE

Seasoned Node developers looking to gain a deeper understanding of the language and best practice

DETAILHIGHLIGHTS

Javascript for Node.JS

 - Recap of Intro and basics
   - The basics of Javascript syntax and semantics. We can keep this very short
     assuming everyone is geting it.
 - Advanced javascript
   - Advanced/newer Javascript features such as Generators, just enough as
     needed for the rest of the course
 - Functional techniques
   - Map, Reduce and using first class functions. We'll talk a bit about what a
     closure is and what that means for your Javascript code.
 - Async techniques
   - Basic async development programming techniques in Javasscript
 - Promises
   - The hows and whys of promises
 - Async await
   - How to take what you know about promises and apply to the new async...await
     synctax
 - Javascript tooling
   - Prettier, linters, flow. Tooling available to make Javascript development
     better

Node

 - The event loop
   - How it works and how interact with it. Difference between setTimeout,
     setImmediate and process.nextTick etc
 - The Node module system
   - What you need to know to understand what happens when you use require
 - Node Events
   - How and when to use the EventEmitter and what its design decisions (eg
     async dispatch) mean for you
 - Node Streams
   - Why they're there and what to use them for
 - Error handling in node
   - Handling errors in synchronous, callback based and promise based code and
     how to make it all work together.
 - Debugging with external debuggers
   - How to connect an external debugger and when it's useful
- Node Performance
   - Basics of writing fast Javascript code
   - Running a profiler

Testing

 - Tour of testing libraries
   - A quick tour thorugh what's available
 - Testing techniques
   - How to write tests for Node applications and what's different from other
     languages
 - Isolation between tests
   - Keeping your tests from messing with each other
 - Testing async functions
   - The various techniques for testing async code. We'll cover both async tests
     and mocking of the async primitives to test async code with sync tests.
 - Mocking in javascript
   - How to mock the components of your application and libraries for isolated
     testing without it being a total pain and without it leaking between tests
