  • Today, we will see one of the simplest ways to create an Angular 5 app & how to integrate it with ASP.NET Core 2.0 Web API.
  • Firstly, create an Angular app by executing this command – – – All the Angular file will be added to our project.
  • Now, change the HTML file app.component.html to display the list of items which we plan to fetch from ASP.NET Core Web API.
  • NET Web API project within the same folder – – So, by executing the below command, we can create a new Web API by using .
  • Now, we need to integrate the Web API with the app by updating angular-cli.

  • More specifically, we’ll implement keyboard support, image preloading and add animations in order to make our overlay more engaging and provide better feedback.
  • Let’s start off by importing the into our application’s like this: – – With this in place, we can go ahead and define our animations with Angular’s Animation DSL and add it to the component via the metadata property in the decorator: – – As you can see we created…
  • Here’s a live demo with all the code above: – – Animations guide our users and the overlay smoothly animates in.
  • Let’s start with the animation callbacks and hook them in the template of our : – – The animation callbacks alone are not very useful, at least not for animating the overlay out.
  • To finish this up we will create a toolbar component, add animations and also make use of the events streams exposed by the remote control to animate the toolbar out before the overlay is closed.

  • Templates are smart, dynamic, they use change detection to update themselves on a moment’s notice when a model is updated, the can manage HTML elements and nested components, enrich the markup with directives and make on-the fly data transformations, and the template syntax is amazing.
  • Pipes in Angular are not literally the same, but the essence lying beneath is similar: a pipe takes some data as in input, performs some operation on it (presumably transforming it to something else; for example, the built-in date pipe in Angular takes a Date object/ISO string and formats it…
  • Any time you move a mouse, press a key or make an HTTP call, the change detection will run, and invoke your method, and if you put some complex logic inside that method, it may affect your app’s performance poorly.Thus, pipes.So, we should use pipes whenever we want to perform…
  • And this is way more beautiful and reusable, than performing logic inside our component (filtering users anytime they change inside a component and reassigning them, so that the template is updated; we can then even set the change detection strategy to OnPush to increase the performance, but this is an…
  • The proposed solution was to make XHR calls for images, setting the headers manually, and this is what I eventually did, but rather than writing some complex login in a component or service, I created a Pipe.

  • In this tutorial, we are going to look at how to create “services” or “providers” in Vue that pull in some data via an HTTP request.
  • Coming from an Angular background we might want to create a “provider” in Vue, and then use whatever Vue’s version of “Http” is to fetch the data.
  • But there is no concept of a “provider” or “service” or “injectable” in Vue, and there is no default library for HTTP requests.
  • Once again, Vue is not concerned with the ins and outs of your application, and it does not provide a “Vue way” to make an HTTP request.
  • If you were to take a look at this in your browser now, you should see something like this: – – An important thing to keep in mind when learning Vue, especially coming from an Angular background, is to remember that although there are many similarities, they are different frameworks…
