Node.js Application Architecture 🇵🇱 🇬🇧 3-4 days

About

Microservices, Cloud and Continuos Delivery heavily influenced the way modern teams build their software.

In this new world there's an increasing need for very fast and performant IO bound services that effectively use server resources and are written in a familiar language. That is where Node.js really shines.

During this training you'll learn to build Node.js apps from A to Z.

What will I learn?

• Create testable APIs and Web Apps talking to NoSQL database
• Evolve application structure based on feedback from code
• Refactor async code from callbacks to promises and enhance it with async/await
• Secure your application against most common attacks
• Translate other architectural characteristics into working code

Agenda

Building RESTful APIs and Web Apps with Express.js

• Express.js: routes, middleware, error handling, template engines
• Resources and Representations
• Collection resource
• HATEOAS - hypermedia
• HTML as media type

Database integration (MongoDB)

• CRUD (Create/Read/Update/Delete)
• sorting and custom pagination

Event Sourcing

• aggregates
• events
• node-eventstore
• command handlers
• event publishing with HTTP

Streams

• streams types
• core streams
• npm stream modules
• pipes and filters architecture

Testing Web apps

• unit testing and component testing
• design for testability
• testing patterns
• dealing with "difficult" dependencies
• tools: mocha, supertest

Structuring bigger apps

• assigning responsibilities in a system and identifying major building blocks
• dependency injection without frameworks
• coding by composition of small libraries and functions (the Unix way)
• evolving application structure according to feedback from code

Dealing with asynchronous code

• real world problems with callbacks
• promises by example
• async/await by example

Securing Web Applications

• test-driven security
• session management and authentication
• secure password handling
• common attacks prevention (XSS, CSRF, DB injection, DoS etc.)
• JWT tokens
• OAuth2

Other architectural characteristics

• performance: finding bottlenecks with clinic.js
• deployability: 12factor approach
• business problem focus: moving operational concerns to the (PaaS) infrastructure
• predictability: thisless programming
