Tip : Use Bit to share and reuse your components between apps. It helps you discover and play with components, using them to build faster.
Give it a try. First, create a new Angular project. For the sake of this post, I have created a simple Angular App.
Go ahead and clone it into your system. Angular comes with a component called ng-template that allows us to declare any part of the Angular template. This is a great way of giving a flavor of dynamic-ness to our template, giving us the ability to take our code and pass it around to other components. In the app. If you open the app now, you will see that the app new text does not render. To be able to grab this template, I have given it a variable called hello. Now go into the Component code of this file, and add the hello variable inside ViewChild.
We now need to be able to access the code that is grabbed by the ViewChild. To do so, we are going to use a lifecycle hook called AfterViewInit. Write the following code inside the Component :. Open your browser developer tools. You will notice there is TemplateRef there that has a couple of properties inside it. We will look into these later on.
If you take a look at the tab. First, remove the text that is being passed by the Hero tab. We want this tab to render the text that is inside the hello variable. Then, go to the tab. Add to the ng-content component, a condition that that says that ng-content should render an empty space if there is no template.
Below this line create a ng-container component that will render the template. Refresh your browser, and you will see the second tab renders the hello variable.
Our tabs are working quite well now, but what we really want to do is pass some data from the outside and render it dynamically. To do this, we can use ngTemplateOutletContext to pass in the data to the ng-template.
First, go to the tab. This Input is going to pass in the data from the outside. We now need to pass on this data on to our template. This is done using the ngtemplateOutletContext property on the ng-container component. The reason I am using an object to pass on the dataContext to the property is that I then get the choice of extending this property so it can take on other types of data.
Now go to the app. We only have one entry inside the heroes array. Now we can leverage this data object and use it inside our component. We also need to define the hero as data. Once your browser refreshes, jump to the second tab and you will see that the name gets properly visualized. To do this, we can use a custom directive that exposes a ViewContainerRef and serves us as an anchor point which we can reference later on. First, go to tabs.Angular 6 Event Binding Example Tutorial.
When the user interacts with a web application in the form of keyboard movement, keystrokes, a mouse click, double click, or a mouseover, on the form submits; it will generate an event.
Those events need to be handled to perform some action. This is where event binding comes into the picture. Let us take an angular 6 example and see how event binding works. Run the Angular development server using the following command. All such action will trigger an event on the page, and the page will respond by listening to these events. An event binding system provides us the way to append a method defined in a component with an event.
Like property binding, event binding is built on top of the events described in the DOM objects. You can capture an event from the view; you do so by wrapping the event in question with parenthesis. Angular provides you with a kind of events from which you can call component logic.
Below example is a simple Angular Event Binding example. It is a button click event. Here, we have defined the click event, and when a user clicks on the event then we can call the function, and we need to define that function inside the component class.
Now, head over to the browser and click on the button and open the dev tools and in the console panel, you can see the button events are the list there. We can get all the details of the event like the source of the event, target element, type of the event, coordinates on the page and screen where the event triggered, as well as many other details.
There are so many types of events in a browser. I am listing a few of them below. You can find more events on this Mozilla page. The primary use of event is to run a piece of code based on the action taken by the user.
In this example, we will see the two events on a single button. So, in this example, when the mouse moves on the button, it will display the coordinates of x and y, and when we click the button, the text will change it to Text Submitted Successfully.

Once I'd finished I was surprised at the relatively small amount of code required to implement a custom modal window, most of the modal 'magic' is done with a handful of css styles see the modal. By default modals are closed on background click, to disable this remove the chunk of code in modal. The example controller passes the modal id from the view, but it could also be set directly in the controller like this:. Below is a breakdown of the pieces of code used to implement custom modal dialogs in Angular 6, you don't need to know the details of how it all works to use the modals in your project, it's only if you're interested in the nuts and bolts or if you want to modify the code or behaviour.
I prefixed the modal element and classes with jw- to prevent conflicts with 3rd party css libraries such as Bootstrap. The modal service manages the communication that's required between angular 6 controllers and modal directive instances.
It maintains a current list of available modals on the page and exposes methods for interacting with those modals. Each modal instance registers itself with the ModalService when it loads using the ngOnInit lifecycle hook, and removes itself from the ModalService when it's destroyed using the ngOnDestroy lifecycle hook.

All other resizable directive concepts I came across include layout logic in the directive. I wanted a directive that only handled the resize logic.
This way, the layout logic is quarantined to the CSS. Include any sides you want to be resizable in an array inside r-directions. Accepts 'top','right','bottom', and 'left'.Ue4 proxy mesh
You can style the handles however you want. Just override the styles in the css in your own stylesheet. For an example using the events, see this codepen. Called repeatedly while the mouse is being moved. By default, only calls once every ms to keep CPU usage low.

For smooth resizing, use the rNoThrottle attribute. This event is emitted during the resizing of the element with the following object as an argument:.

A lightweight directive for creating resizable containers.Most of the time, we use CSS media queries to handle responsive, screen size changes to layout our content differently. However, there are times where CSS media queries alone isn't sufficient for that. We need to handle the responsiveness in our code.
In this article, I would like to share about how to detect responsive breakpoints in Angular, with a twist - we don't maintaining responsive breakpoint sizes in your Typescript code because responsive breakpoints are already defined in CSS.
Let's start. We will be using CSS Classes to determine the current responsive breakpoints. There are 5 breakpoints in Bootstrap CSS.
The CSS classes to determine the visibility of each breakpoints is:. The CSS display property will be toggled between none or block. We will apply these classes to HTML elements. Everytime when screen size changes, we will loop and find the HTML element with style display: blockthis is how we will detect the current breakpoint.
It is an enum. Let's create the screen size enum You may create a new file or just place the enum in same component file. Also, remember to add Bootstrap to your project! You may add it via npm or yarn, but in this example, we will use the easier way. Add the cdn link in index. Now we have the component code "almost" ready, let's start implementing our resize service. Next, let's go back to our size-detector component and update the detectScreenSize logic.
You may place the size-detector component under our root component app-component. For example:. In this example, I have another hello-component in the app-componentbut that doesn't matter.
Since I place the component in app-componentmeans I can use the ResizeService everywhere directives, components, services, etc. In the above code, we detect the screen size changes and simply display the current screen size value. One of the real life use case scenario might be you have accordion on screen.
It is an integral part of any modern web application. Animation not only helps us create a great UI but it also makes the application interesting and fun to use.How to add AOS Animation On Page Scroll in angular 6 - Angular 6 AOS Animation
A well-structured animation keeps the user engaged with the application and enhances the user experience. Angular allows us to create animations which provides us similar native performance as CSS animations.
In this article, we will learn how we can create animation using Angular 6. Download the source code from GitHub. Animation involves transition from one state of an element to another state. Angular defines three different states for an element:.
To show the animation transition from one state to another, we define animation transition timing in our application. This property represents the time our animation takes to complete from start initial state to finish final state.
We can define the duration of animation in the following three ways:. This property represents the duration between the animation trigger and the beginning of the actual transition.Hobart murders
This property also follows the same syntax as duration. Delay is an optional property. This property represents how the animation accelerates or decelerates during its execution. We can define the easing by adding it as the third variable in the string after duration and delay. If the delay value is not present, then easing will be the second value. This is also an optional property.
These commands will create a directory with the name ngAnimationDemo and then create an Angular application with the name ngAnimation inside that directory. This will open a terminal window in VS Code.
To use Angular animation we need to import BrowserAnimationsModule which is an animation-specific module in our application. Open the app. The syntax for the animation is shown below:.
Here we will use a property called animations. This property will take an array as input. Each trigger has a unique name and an implementation.The Window enables you to set its width and heightand change its dimensions by dragging the resize handles. To define the dimensions of the Window, use its width and height bindings.
The width and height bindings support two-way binding. By default, the Window enables you to resize it by dragging its edges resize handles. To control this behavior, use the resizable binding. You can also control the minimum allowed dimensions of the Window by using the minWidth and minHeight bindings.
