A list of tools available in Lightning and frequently used by Salesforce Developers include – Salesforce Lightning Component Framework, Lightning Connect, Lightning App Builder, Lightning Process Builder, and Schema builder, Lightning Experience, Lightning Exchange, Lightning App Builder, or Visual building tools etc.
In the same way What are two benefits of the lightning component framework? Benefits of Using Lightning Component Framework
Can build responsive applications. Uses Javascript on the client side and Apex on the server side. Utilizes a stateful client and a stateless server. It means, it calls the server only when is necessary incresing the effience of the app.
What is the advantage of lightning component framework?
Faster development – : Empowers teams to work faster with out-of-the-box components that function seamlessly with desktop and mobile devices. Device-aware and cross browser compatibility – : responsive design,supports the latest in browser technology such as HTML5, CSS3, and touch events.
What is a characteristic of the lightning component framework?
It uses JavaScript on the client side and Apex on the server side. The benefits include an out-of-the-box set of components and interfaces, event-driven architecture, and a framework optimized for performance.
Why do we use LWC?
Lightning Web Components (LWC) is a stack of modern lightweight frameworks built on the latest web standards. It is a DOM (Document Object Model), element created through reusable code and is used to generate a dynamic interface without using JavaScript or building a Library.
Which resources can be included in a lightning component bundle?
The bundle contains all the required resources related to a component like javascript controller, javascript helper, renderer, CSS styles, etc. A basic lightning component contains the design of a page in Html with some lightning tags. The component uses JavaScript on the client-side and Apex on the server-side.
Why is LWC faster than aura?
Faster Sites & Better Performance : LWC is a lightweight framework which is built on web standards and because there is no added abstraction layer, LWC is likely to render faster than aura components since performance is important to deliverability.
Why is LWC faster?
As LWC builts on web components, It makes LWC extremely lightweight & efficient in memory management. That’s the reason LWC runs much faster than Aura lightning components.
What is difference between LWC and Aura components?
Aura-based Lightning components are built using both HTML and JavaScript, but LWC is built directly on the Web stack. A developer who works on LWC is not only using coding skills on a particular framework but in other frameworks like React or Angular, which are based on the Web Stack.
Which resource can be used to fire events in the Lightning component framework?
The lightning documentation says that you can only register/fire events from built-in resources such as components or related controllers/helpers. It appears you probably want to write a wrapper function in your component which will call the third party code and fire the event when done.
What is Aura dependency?
The <aura:dependency> tag enables you to declare dependencies, which improves their discoverability by the framework. The framework automatically tracks dependencies between definitions, such as components, defined in markup. This enables the framework to send the definitions to the browser.
What is Salesforce lightning component?
Lightning Components are a user interface (UI) framework that is used to create applications for desktop and mobile technologies. Salesforce Admins deploy these components to construct single-page web applications that provide an end-to-end experience on the platform for a variety of functions.
What is shadow DOM in LWC?
Shadow DOM is a standard that encapsulates the internal document object model (DOM) structure of a web component. Encapsulating the DOM gives developers the ability to share a component and protect the component from being manipulated by arbitrary HTML, CSS, and JavaScript.
Why LWC is faster than aura?
Faster Sites & Better Performance : LWC is a lightweight framework which is built on web standards and because there is no added abstraction layer, LWC is likely to render faster than aura components since performance is important to deliverability.
Which is better LWC or aura?
While the Aura framework needed to implement a proprietary component model, proprietary language extensions, and proprietary modules, LWC uses web stack features implemented natively by browsers, which means that LWC apps are substantially more performant.
What is bubble and capture phase in lightning?
The framework supports capture and bubble phases for the propagation of component events. These phases are similar to DOM handling patterns and provide an opportunity for interested components to interact with an event and potentially control the behavior for subsequent handlers.
What is difference between controller and helper in lightning?
A controller contains functions to handle events in the component. A helper contains utility functions that can be reused in the component bundle; for example, by a controller and a renderer. You don’t have to use a helper but it can be helpful (pardon the pun) for reuse.
What is event in lightning?
Events are fired from JavaScript controller actions that are typically triggered by a user interacting with the user interface. There are two types of events in the framework: Component events are handled by the component itself or a component that instantiates or contains the component.
What is difference between LC and LWC?
The most notable difference between LWC and LC is the component bundle structure. While you will find similarity between some of the files in the bundle, but there are major differences. LWC component requires a folder to host all component files. The folder sits on the root /lwc folder which hosts all the LWCs.
What are decorators in LWC?
The Lightning Web Components programming model has three decorators that add functionality to property or function. Decorators dynamically alter the functionality of a property or function.
Can I learn LWC without aura?
OPINION based: You can go to LWC, there are some features which would require a use of AURA so you should be able realize when that happens. Also depending on the project if you are from an IT services company, you may need to work with AURA (or event VF for legacy orgs).
