Client Testimonials

The experience I've had with other firms is in direct contrast to what FullStack did. I'm comparing them with two other firms I worked with in the past. They care a lot about what their clients are doing. They bring their ideas and concepts to the table. I felt like they were on my team. They added a lot of value in terms of ideas and continue to do so. No matter who's working on the project you feel like they care about the work that's being produced.

FullStack Labs' managers have been engaged throughout. The whole project management staffing, matching team to task has been fantastic. All their staff is very committed. I'm very aware of how much bureaucracy there is in the tech world, and we've gotten nothing but solutions. I am totally happy with their approach to everything, their integrity, honesty, the whole thing. It's great.

We were very happy with the way the whole process was facilitated. We started talking to FullStack Labs three months before we signed any contract with them. We met with them in person several times. We wanted to find out what their philosophy is. Both Brian and David are fathers with young children, so they understand the importance of the work we are doing. That shows through in their work. It was obvious they cared deeply.

Essential Technical Angular.js Interview Questions

FullStack Labs is a leading team of Angular.js developers, engineers, programmers, coders, and architects. Uber, Siemens, and hundreds of other companies have chosen us for their mission-critical software development projects. Angular.js is a crucial tool to develop your project, here are a few Angular.js Interview Questions you can use to screen your Angular.js candidates:

Q: What is the difference between Components and Directives?

Components break up the application into smaller parts; whereas, Directives add behavior to an existing DOM element.

Q: What is the use of @Input and @Output?

When it comes to the communication of Angular Components, which are in Parent-Child Relationship; we use @Input in Child Component when we are passing data from Parent to Child Component and @Output is used in Parent Component to receive an event from Child to Parent Component. 

Q: Could you describe some of the differences between Angular >2 and Angular 1.x?

  • AOT (ahead-of-time) compiler, code is converted at build time and not runtime
  • Better speed and performance
  • No $scope
  • Dependency injection was improved and simplified
  • Uses Typescript

Q: What are the compilation methods Angular offers to compile your app and when are they used?

  • AOT - ahead-of-time, used when deploying your app to prod, the `--aot` flag is added by default
  • JIT - just-in-time, used on development when you run `ng serve` or `ng build` without `--aot` flag

Q: How can an Angular app be attacked?

  • Injecting dynamic html content in your views or components, sanitize it first
  • Using Angular versions out of date
  • Using Angular APIs marked in the documentation as “Security Risk.”

Q: What is dependency injection and how can you use it in Angular?

  • Dependency injection is a technique whereby one object (or static method) supplies the dependencies of another object. A dependency is an object that can be used (a service). An injection is the passing of a dependency to a dependent object (a client) that would use it. The service is made part of the client's state.[1] Passing the service to the client, rather than allowing a client to build or find the service, is the fundamental requirement of the pattern.
  • Using the @Injectable decorator identifies services and other classes that are intended to be injected. It can also be used to configure a provider for those services.

Q: How would you use redux style (state management) concepts with Angular 2?

  • Angular 2 with state management can be achieved by using Observables / RxJS / Effects(SideEffects).
    - Effects to make api calls, process response and dispatch state changes to update store.
    - RxJS to maintain the store.
    - Observables to listen to the store changes and update UI accordingly.

Q: Explain the lifecycle hooks of an Angular app and their sequence?

  • Lifecycle is a number of different phases a component goes through from creation to destruction, we can define some specific method in order to hook into any of those phases to obtain control of our component.
  • Lifecycles
    - constructor: This is invoked when a component or directive is created by calling new on the class.
    - ngOnChanges: Invoked every time an input property is changed in the component.
    - ngOnInit: Invoked when given component has been initialized. This hook is only called once after the first ngOnChanges
    - ngDoCheck: Invoked when the change detector of the given component is invoked.
    - ngOnDestroy: This method will be invoked just before Angular destroys the component.
  • The following hooks are only called for components and not directives:
    - ngAfterContentInit: Invoked after Angular performs any content projection into the components view
    - ngAfterContentChecked: Invoked each time the content of the given component has been checked by the change detection mechanism of Angular.
    - ngAfterViewInit: Invoked when the component’s view has been fully initialized.
    - ngAfterViewChecked: Invoked each time the view of the given component has been checked by the change detection mechanism of Angular.
