  • In order to get the data from service call we have to handle it using then() method.
  • By default, Angular built-in HTTP services return Observable.
  • To support toPrimise() method, first we have to import toPromise() from rxjs as below, – – By default, Angular built-in HTTP services return Observable.
  • We can convert the promised call back to Observable also by using Observable.from promise(HTTP call) method.
  • We can convert the Promise call to Observable by using fromPromise() method, as below.

  • Here are the steps: – – dbpath : specifies the path of the data files – – logpath : specifies the path of the log file – – verbose: specifies how verbose we want out log files to be, in this we want our log files to be very verbose…
  • The settings is from v to vvvvv  going from least to most verbose – – 4.
  • Save the file,  put the path C:\Program Files\MongoDB\Server\3.4\bin into the Environment Variables “Path” varible, now open up the command line utility  type in the following command to use the configuration file

  • As a person new to both JavaScript and Angular 2 I found this course extremely helpful because Max does a great job of explaining all the important concepts behind the code.
  • This Course uses TypeScript – – TypeScript is the main language used by the official Angular team and the language you’ll mostly see in Angular tutorials.
  • The powerful features and capabilities of Angular allow you to create complex, customizable, modern, responsive and user friendly web applications.
  • Due to the drastic differences between Angular 1 and Angular (=Angular 4) you don’t need to know anything about Angular.js to be able to benefit from this course and build your futures projects with Angular.
  • Get a very deep understanding of how to create Angular applications – – This course will teach you all the fundamentals about modules, directives, components, databinding, routing, HTTP access and much more!

  • The Angular team has announced the first stable release of its Component Development Kit (CDK).
  • The CDK was built for developers to add high quality behaviors to their components with minimal effort.
  • “The Angular CDK gives developers solid, well-tested tools to add common interaction patterns with minimal effort.
  • The CDK is still relatively young, but the team hopes all Angular component libraries will eventually be able to leverage the CDK.
  • Going forward, the team will focus on building a new component, improving the positioning strategy for overlays, adding utilities and directives for drag-and-drop interactions, providing a dialog subpackage, and adding a way to inline SVGs for animation and styling.

  • In this quick tip I will show you how you can preserve your HTML output with AngularJS.
  • We’ll assume that you have replaced line breaks (if necessary) with a – – – You could then use the following HTML to output the data: – – The problem now is, that instead of a new line, the text “ – ” will be part of the comment text….
  • Prior to AngularJS 1.2, you could fix this problem by editing your HTML like this: – – This will then allow the HTML inside of the comment and parse the output as real HTML instead of text.
  • This custom filter will make sure that our HTML doesn’t get filtered out by AngularJS 1.2/AngularJS 1.3 or later – – We will name this filter “unsafe”.
  • Now, modify your HTML code from this: – – And change it to this: – – This will run your comment.text through the “unsafe” filter we just created, and once again, your output will have the HTML parsed properly.

  • By “accessibility,” I mean designing software and websites using large enough fonts, high contrast colors, big enough buttons (especially relevant in the era of touch screens), making sure all elements have textual descriptions for screen readers, and that everything is navigable and accessible with the keyboard.This post is based on…
  • And speaking of receptors, we also need to remember that not everyone has all of them — some people are color blind and can only see certain colors.My point is that, so sooner or later, we will all be a part of the target audience for accessibility.Considerations for AccessibilityWhile adding big buttons…
  • When we design our apps and web pages with accessibility in mind, we can them them out by making sure they can get to all interactive elements using the tab key, and that we use the appropriate markup (or the role attribute) to distinguish headers, links, and so forth.Here is…
  • We will add a (keydown)=”onKeydown($event)” attribute to our span element, which will let us implement the event handler in our controller, and then we will add the following code to the control — basically accounting for up, down, left, right— allowing manipulation of this element using just the keyboard:You could even further…
  • 1 star’ : `${this.value} stars`; } else { return ‘No rating’; }}Finally, we can add several more ARIA attributes that describe the slider’s range and current value:span … aria-valuemin=”0″ [attr.aria-valuenow]=”value” /One final thing: we also want to test this element with the color blindness chrome extension I mentioned above.

  • Getting to Know the @Attribute Decorator in AngularThe @Attribute decorator is one of the least known and least used, but in some cases, it can bring a performance boost to the application.The @Attribute decorator returns the value of the specified attribute from the host.Let’s say that we have a core button…
  • Because we are using an Input(), Angular will still create a binding for the type property and will check it with every change detection cycle, even though this is a static string.To illustrate this, let’s see the compiled code.As you can see, when we trigger the change detection by emitting…
  • As a general rule, I prefer the @Attribute() approach when the string is a fixed value that never changes.Note that in this case, it is possible to take it further, remove the ngClass and leverage CSS selector, but I’m sure you got the idea.Follow me on Medium or Twitter to…
