Serverless development with MongoDB Stitch allows developers to build applications without managing infrastructure. Stitch provides four main services - QueryAnywhere for data access, Functions for server-side logic, Triggers for real-time notifications, and Mobile Sync for offline data synchronization. These services integrate with MongoDB and other data sources through a unified API, and apply access controls and filters to queries. Functions can be used to build applications or enable data services, and are integrated with application context including user information, services, and values. This allows developers to write code without dealing with deployment or scaling.

https://youtu.be/_yLt_abcK2w Angular is a TypeScript-based open-source front-end platform that makes it easy to build applications with in web/mobile/desktop. The major features of this framework such as declarative templates, dependency injection, end to end tooling, and many more other features are used to ease the development. Angular 7 is a Javascript framework built around the concept of components, and more precisely, with the Web Components standard in mind. It was rewritten from scratch by the Angular team using Typescript (although we can use it with ES5, ES6, or Dart as well). Angular 7 is a big change for us compared to 1.x. Because it is a completely different framework than 1.x, and is not backward-compatible.

AngularJS is an open-source JavaScript framework for building dynamic web applications. It uses HTML as the template language and allows extending HTML vocabulary for the application. The key concepts covered in the document include modules and dependency injection, data binding using controllers and scopes, services, filters, form validation, directives, and routing. Various AngularJS features like modules, controllers, services, directives etc. are demonstrated via code examples. The document provides an introduction to core AngularJS concepts through explanations, code samples and a demo.

Here are some answers to common Angular interview questions. That's Angular 2+, not AngularJS. They’re quick, not really extended and are not in any particular order. Let’s get it on!

This document provides an overview of Angular 2 and Rxjs. Some key points covered include: - Angular 2 is backed by Google and designed to be faster and more memory efficient than Angular 1. It uses TypeScript and focuses on components. - Bootstrapping, modules, directives, bindings and pipes work differently in Angular 2 compared to Angular 1 with fewer overall concepts. - Observables and operators from Rxjs allow for asynchronous programming and composing asynchronous operations. Common operators like map, filter and flatMap are discussed. - Services can be used to share data between components. Components follow a lifecycle with hooks like ngOnInit and ngOnDestroy. -

The document discusses Angular modules, directives, and components. Angular modules help organize an application into blocks of functionality using the @NgModule annotation. There are three types of directives - components, attribute directives, and structural directives. Components are a subset of directives that use the @Component annotation and define templates to specify elements and logic on a page. The metadata definitions for @NgModule, @Directive, and @Component are also described.

Guice is a lightweight Java dependency injection framework that allows developers to declare dependencies through modules and inject them using annotations. With Guice, developers can define bindings between interfaces and implementations, and annotate constructors and fields to specify injection points. This reduces boilerplate code compared to alternatives like implementing dependency injection by hand. Guice validates dependencies at startup and handles circular dependencies automatically.

Dependency injection is a design pattern that removes tight coupling between objects and their dependencies. It allows for objects to have their dependencies satisfied externally rather than internally. There are three main types of dependency injection: constructor injection, setter injection, and interface injection. Constructor injection passes dependencies through a class's constructor, while setter injection uses properties, and interface injection relies on implementing a common interface. Dependency injection promotes loose coupling, testability, and flexibility between classes.

The document provides an overview of Spring MVC and best practices for implementing the MVC pattern with Spring. It discusses the basic components of MVC - Model, View, Controller - and how Spring splits code into these areas. It describes annotations used in Spring MVC like @Controller, @RequestMapping, and @ModelAttribute. It also covers common tasks like handling user input, populating the model, creating forms, and using Bean Validation. Finally, it discusses additional topics like view resolvers, exception handling, and file uploads.

This document discusses integrating Apache Bean Validation with Google Guice. It describes how to bootstrap Bean Validation using Guice, obtain ConstraintValidator instances via Guice injection, require injection of javax.validation components, and intercept methods to validate arguments. Integrating the two allows for dependency injection with Bean Validation and easy validation of method arguments using annotations.

This document discusses effective practices for dependency injection (DI). It begins with a quick DI refresher and then provides guidelines for DI such as: explicitly defining dependencies, injecting exactly what is needed, preferring constructor injection, avoiding work in constructors, and avoiding direct dependencies on the injector. It also discusses testing code using DI, applying DI to existing code, and techniques for migrating code to use DI such as bottom-up or top-down approaches.

JSR-303 defines a metadata model and API for JavaBean validation using annotations. It allows for validation on both the server and client sides. Implementations include Hibernate Validator and Apache Bean Validation. Validation can be configured using annotations and custom constraints can be defined. Errors are handled by binding results to the model in Spring MVC. Both property and object level validation can be tested.

This document provides an overview of the Guice and Gin dependency injection frameworks. It discusses key features and differences between the two, including how Guice supports both server-side and client-side Java applications while Gin is tailored specifically for GWT client-side apps. Examples are given of basic usage and configuration for common tasks like singleton scopes and dependency injection.

Spring 3 emphasizes annotation configuration over XML. Key changes include support for JSR 250, 299/330, and 303 annotations as well as a simplified MVC framework with @Controller and @RequestMapping annotations. Validation is integrated using JSR 303 annotations and executed automatically by the framework. Configuration is also simplified through @Configuration classes and the @Bean annotation.

This document provides an overview of the Guice and Gin dependency injection frameworks. It discusses key features of Guice like annotation-based configuration, scopes, and type-safe injection. It compares Guice to Spring, noting Guice's simpler configuration. It also covers using Guice and Gin in web applications and GWT clients. Additional topics include the Warp utilities, configuration options like @Named, and limitations of Gin for GWT apps.

This document discusses different methods for implementing validation in Entity Framework models, including: - Using data annotations to enable client-side and server-side validation. Properties can be marked as required, have a maximum length, etc. - Implementing validation logic in the DbContext using the Fluent API. This allows validating properties when the model is created. - Implementing custom validation by having entities implement IValidatableObject and adding validation logic. - Overriding ValidateEntity in the DbContext to add validation that runs when entities are added, modified or deleted. - Explicitly triggering validation by calling GetValidationErrors instead of just waiting for SaveChanges.

This document summarizes the Guice dependency injection framework. It provides an overview of key Guice concepts like dependency injection, modules, and bindings. It also discusses Guice extensions like Warp Persist for persistence and transaction management and Google GIN which compiles Guice configuration at compile time for improved performance.

Apache Wicket is constantly growing in popularity throughout all kinds of projects. However Wicket doesn't come out of the box with a built-in Java EE support. Integration to CDI is missing and the same is valid for Bean Validation support for example. This session demonstrates how you can user CDI, Conversations and Bean Validation together with Apache Wicket. The first part of the talk will consist of a small slide-driven theoretical part whereas the second part will consist of a coding session that demonstrates hands-on how to hook everything together.

This document discusses architecting a GWT application with the GWT-Platform framework. It recommends using a Model-View-Presenter architecture and describes some MVP frameworks for GWT including gwt-platform. It provides an overview of how to structure an app with GWT-Platform and GXT3 including using places, tokens, presenters and dependency injection with GIN. It also covers styling the app with ClientBundle and includes sample code for creating a default presenter.

The document discusses migrating an existing authentication system at Columbia University to the Central Authentication Service (CAS). Specifically, it addresses: 1) Integrating the legacy service registry and custom attributes into CAS. 2) Adding support for the legacy "WIND" authentication protocol to CAS to allow existing clients to continue using either the legacy or CAS protocols during migration. 3) Customizing CAS login behavior and UI to match the existing system.

CDI provides standards-based and typesafe dependency injection in Java EE 6. It integrates well with other Java EE 6 technologies like EJB, JPA, JSF, and JAX-WS. Portable extensions facilitate a richer programming model. Weld is the reference implementation of CDI and is integrated into application servers like GlassFish and JBoss.

The document discusses dependency injection (DI) using RoboGuice in Android applications. DI makes code more concise, modular, and easier to test by allowing classes to declare dependencies without knowing how they are satisfied. RoboGuice uses annotations to inject dependencies into activities and services. It allows for loose coupling, high cohesion, and centralized configuration through bindings. DI improves testability by increasing controllability, observability, and isolation of units under test.

Introduction of Dependency Injection pattern, and integration of 'Symfony Injection' component and 'Zend Framework'.

Le temps est révolu où Java EE ne serait qu’à développer des applications de mise à jour de données, avec JSF / EJB / JPA. Aujourd’hui Java EE s’est assoupli et s’est ouvert sur le monde, avec CDI comme clé de voûte et a repoussé nos limites grâce à des capacités d’extension puissantes et faciles d’utilisation comme JCA. Dans un premier temps, nous reviendrons rapidement sur la place de CDI dans JavaEE 7 et sur ses mécanismes d’extension. Dans un deuxième temps, nous verrons les techniques de connecteurs JCA et comment ils peuvent aussi constituer une possibilité d’ouverture simple à mettre en œuvre. JCA fournit des techniques pour gérer des connexions sortantes ou entrantes, sur des formats ou protocoles variés.

1. Validations in MVC can be done using data annotations attributes on models, custom validation attributes, and implementing validation interfaces. 2. Data annotations attributes provide both client and server validation without additional coding and include attributes like Required, StringLength, Range etc. 3. Custom validation attributes can be created by deriving from ValidationAttribute and overriding IsValid. These work on the server. 4. Client side validation is enabled by including jQuery and validation scripts. Data annotations are translated to HTML5 data attributes that jQuery validation understands.
