The document discusses an architecture for mobile applications using MVC patterns. It describes layers for models, views, controllers, storage, and routing. The model layer defines app domains and interfaces with storage. Storage handles persistence and converts data. Controllers are kept light by coordinating views through a router layer. Dependencies are injected to improve testability and reuse of models, storage and views across the app.
1) The document discusses how to create reusable generic form controls and reusable forms in Angular. 2) It demonstrates implementing the ControlValueAccessor interface to create a custom input component that can be controlled via inputs and outputs. 3) A technique for creating reusable forms is presented where the FormGroupDirective is used to inject the parent form and avoid duplicating the form definition code.

Angular 2 is the next version of the AngularJS framework. It was released in 2016 after 2 years of development. Some key features of Angular 2 include optimized performance for both desktop and mobile applications, ahead of time compilation for faster loading, and native support for reactive programming. The document then provides examples of core Angular concepts like components, directives, services, dependency injection and change detection. It explains how Angular 2 applications are bootstrapped and discusses some of the internal workings like the change detection engine.
This document provides an introduction to Angular 2, including: - Angular 2 is a JavaScript framework for building single-page applications that uses dependency injection, change detection, and components. - TypeScript allows adding types to JavaScript for complex apps and is used extensively in Angular 2. - The Angular 2 ecosystem utilizes decorators like @Component and @NgModule to define metadata for components and modules. Components also have lifecycle hooks. - The document demonstrates how to set up an Angular 2 app using the Angular CLI, including creating modules, components, services, and bootstrapping the app. It compares the component architecture between Angular 1 and 2.
Mike North discusses the W3C web component specification including HTML imports, templates, custom elements, and shadow DOM. He explains how each part works and provides code examples. Frameworks like Ember and React handle these concepts through their own abstractions like components, templates, and CSS encapsulation techniques. North demos a simple component built with these web component standards.
Angular 2 is a rewrite of AngularJS for modern web development. It improves on AngularJS by being faster, easier to use and learn, and built on proven best practices. Some key differences include components replacing controllers, unidirectional data flow instead of two-way binding, and type-based dependency injection rather than naming. While the core concepts remain similar, the implementation in Angular 2 is cleaner. However, setting up a full Angular project can still be complicated due to dependencies on build tools and module bundling.

It emphasizes that Angular is faster, simpler and optimized for responsive web design compared to AngularJS. The document concludes with noting a demo using the Angular CLI and Spotify API.
This document provides an overview of Scala self-types and the Cake Pattern design pattern for dependency injection in Scala. It begins with an example of defining interfaces for components in a car, like Engine and Car, and using inheritance and composition to assemble them. It then introduces self-types as a way to declare dependencies between traits. The document explains how the Cake Pattern uses traits and self-types to assemble components in a typesafe way at compile-time without external configuration. It discusses pros and cons of this approach and cautions about exposing fragile self-type dependencies in libraries.

This document discusses how Stencil can help address problems with building web applications using traditional frameworks and libraries. Stencil is a compiler that generates custom elements from components written with its API, providing features like virtual DOM, reactivity, and JSX without coupling to a specific framework. It addresses issues like verbose custom element syntax, lack of runtime features, and polyfill needs. The document demonstrates how to create and consume Stencil components, and how it allows infrastructure components to be reused across frameworks by compiling to standard web components.
Web components consist of three main technologies: HTML template, Shadow DOM, and Custom Elements. They aim to encapsulate reusable code into packages for maximum interoperability across platforms. Creating a web component with Angular involves generating a component, adding ViewEncapsulation.ShadowDom for styling encapsulation, and using the createCustomElement method to define the custom element. The component can then communicate with an Angular project using property binding. Future directions include lit-html for template literals and lit-element as a base class. Theming can be done with CSS Shadow Parts. Overall, web components provide maximum interoperability and Angular supports their creation and use within projects.
This document discusses unit testing in Angular 2. It introduces the Angular 2 test API and differences from previous versions. It then covers decisions to make when unit testing like what framework to use and how to set up tests. Finally, it provides recipes for unit testing different scenarios like simple components, components communicating with services, routing, and nested components. It emphasizes the importance of writing unit tests and lists resources for learning more about Angular testing.
Angular 6 architecture organizes code into modules, components, services and more. The document discusses Angular CLI commands, project structure, and key concepts like lazy loading modules.

The document provides information on installation, project structure, configuration, writing tests, using page objects, test execution, and ways to extend Nightwatch's functionality through custom commands/assertions.
For a number of years now we have been hearing about all of the benefits that automated unit testing provides like increasing our quality, catching errors earlier, ensuring that all developers are testing in the same manner and deploying updates with high confidence that nothing will break. Testing a Web UI though was difficult and fragile which meant that typically we had no automated unit test for our Web UI. This is no longer the case with the latest release of Angular. Unit testing is now a first class citizen in Angular. Out of the box, the project generated by the Angular CLI has unit testing setup with Karma and Jasmine and includes sample tests. Generating new components, services, and pipes includes the unit test Spec file already wired up. Thus allowing you to focus on writing your unit tests and not on the infrastructure needed to get them running. The barriers to writing unit test have been destroyed. This talk will walk through getting started unit testing your Angular components, services, and pipes. Along the way I will share the tips and tricks that I have learned as I have implemented unit testing on my Angular projects at a Fortune 100 company. You will walk away ready to immediately implement unit testing on your Angular project.
The document discusses various techniques for optimizing mobile test automation, including: 1) Mocking API responses and disabling animations to speed up test execution times significantly. 2) Implementing shortcuts like unique IDs and headers to scripts tests once across platforms. 3) Saving time by parallelizing test execution and preventing inconsistent test data issues.

Validating user input for accuracy and completeness helps in improving overall data quality. Angular and its form package turns up with a Validators class that has some beneficial validators like minLength, maxLength, required and pattern. However, occasionally if we wish to validate different fields under more complex/custom rules we can make optimum use of custom validator. Defining custom validators while using Reactive Forms in Angular comes very easy as they are more of regular functions. One can conveniently generate function for custom validators within the component file in case the validator is not supposed to be used elsewhere.

This document summarizes Angular component communication patterns. It discusses using @Input and @Output to communicate between parent and child components. It also covers using a shared service to communicate between siblings and across the component tree. Services can utilize BehaviorSubject to share state updates through observables. Larger applications may use a state management library like NgRx to introduce a single source of truth via a centralized store.
The document discusses protocol-oriented programming in Swift. It begins by comparing protocols in Swift vs Objective-C, noting key differences like protocol inheritance, extensions, default implementations, and associated types in Swift. It then defines protocol-oriented programming as separating public interfaces from implementations using protocols that components communicate through. Examples are provided of using protocols for data types, dependency injection, testing, and real-world UIKit views. Protocol-oriented programming is said to improve reusability, extensibility, and maintainability over inheritance-based approaches.
