Presentation Transcript

  1. Testable Web Applications With AngularJS and NodeJS Presented by Greg Burke Web Application Developer – FPI greg.burke@financialpartners.com

  2. Angular and Node • Angular JS: comprehensive MV* framework • Contains the building blocks for a SPA • Node JS: server-side Javascript • Web server, test runner

  3. Outline • Brainstorm • Overview of SPA • Problems • Framework Discussion • Angular Demo • Testing Demo • Other topics in Node/Angular

  4. Brainstorming • Discuss the different elements needed in order to build a large enterprise application

  5. Considerations • SPA? • MV*? • Controls? • Module loading? • Unit Testing?

  6. SPA • Only one true “page” • Multiple “views” • Async requests • Need to handle back button and navigable views • Sammy.js, JQueryAJAX, Amplify • Demo

  7. MV* • Separation of concerns • Two-way data-binding • Knockout.js, Backbone.js

  8. Controls • Grids • Date Pickers • Tree views • Input Masking • KendoUI and JQueryUI

  9. Module Loading • Dependency management • Code separation • RequireJS

  10. Unit Testing • Specifications • Modules • MV* compatibility • Qunit, Jasmine

  11. Issues • Many different libraries • Not cohesive • Difficult to test • Compatibility issues • Onboarding

  12. Demo: Testability • Testing with this setup can be problematic

  13. Frameworks • “Inversion of Control is a key part of what makes a framework different to a library. A library is essentially a set of functions that you can call, these days usually organized into classes. Each call does some work and returns control to the client.” – Martin Fowler

  14. Discuss: Framework or Not

  15. Requirements • Inventory management app • Define a household inventory • Indicate when items are used • Generate a grocery list of needed items

  16. Angular JS • MV* framework • Cohesive and “opinionated” • All the necessary functionality for SPA • Helps you write testable code (DI) • AngularUI Team works on UI controls

  17. Controllers • Contains logic for rendering your View • Fields for data-binding • Avoid DOM manipulation • May be associated with a template • Example

  18. Directives • New tags/attributes • “Custom bindings” • Nested templates • DOM manipulation • Example

  19. Services • Share logic between controllers • Keeps controllers clean • Business logic • Example

  20. Resources • Similar to service proxy • Interact with any RESTful API

  21. Overview • Controllers • Directives • Services • Resources

  22. Full App Demo

  23. Testing • Dependency injection • Jasmine • Karma Testrunner

  24. Dependency Injection • Dependency injection is a software design pattern that allows the removal of hard-coded dependencies and makes it possible to change them, whether at run-time or compile-time.

  25. Full Testing Demo

  26. Pluralsight • AngularJS Fundamentals • AngularJS for .NET Developers • AngularJS In-Depth • Application Building Patterns with AngularJS • Building a Site with Bootstrap, AngularJS… • Building AngularJS and Node.js Apps… • Building Apps with Angular and Breeze
