Learn Practical Web Components Quickly

Building Our First Web Component 6 lectures 31:22 The Course Overview This video will give you an overview about the course. Custom Elements Often, developers end up repeating the same structure of code unnecessarily. Web components help you resolve the unnecessary replication of code. • The first step to create a web component is to create a custom element of your own • To create a custom element, create a class and define a custom hyphenated name for the element • Add content you want to add to your custom element Shadow DOM For web components, you need to have a DOM tree that cannot be accidentally accessed from the outside. Shadow DOM helps you encapsulate a part of the DOM. • To create a shadow DOM, you need to access an element and attach shadow to it • You need to ensure that mode is open so that you can reference shadow outside • Add HTML and style which can only be accessed by the shadow and not by anyone else HTML Templates To resolve the problem of rewriting unnecessary code, we need to create a structure which can be reused with different content. HTML Template helps you create a structure which can be reused unlimited times. • Create HTML code inside a template tag which will not be rendered until called upon • Copy the template code into a variable using importNode • Add content as many times as you want and add the content to any part of HTML Creating Reusable HTML Templates To create our blog page, we need two web components – a card for housing all the titles and a modal for showing the content inside the card. • Create a HTML template which has a title, subtitle, and synopsis elements • Fetch the content of HTML template and store it in a variable • Run through data and add it to template’s placeholder elements Joining the Dots Add Shadow DOM and create a custom element to complete our first web component – Card component. • Create a class for 'card' and define a custom name for it • Create a shadow root and add template data to the ShadowRoot instance • Import the custom element in the index.html file and call it Building Our First Web Component - Quiz Building Our First Web Component. 6 lectures 31:22 The Course Overview This video will give you an overview about the course.
