What is difference between VF page and lightning?
Visualforce assists in the creation of personalised user interfaces with native hosting as a platform that includes tag-based markup language and server-side controllers. Lightning is a cutting-edge user interface framework that helps developers create immersive web applications for both mobile and desktop devices.
How does client side caching improve lightning performance?
Client-side data caching improves performance by sharing data among components, which significantly reduces the number of server round-trips. LWC has two built-in mechanisms for client-side caching: Lightning Data Service and cacheable Apex methods. If neither of these work for your purposes, you can also implement a custom caching solution.
How to optimize the performance of Lightning components?
Optimize server round-trips: Before making a call to the server, make sure there’s no other option to obtain the data. When appropriate, consider passing data between components (using attributes, events, or methods) rather than retrieving the same data in different components.
How are server actions used in Lightning components?
Server actions support optional client-side caching, and the Lightning Data Service is built on top of a sophisticated client caching mechanism. In this article, we focus on server actions and explore how to use them to cache the response of server method calls at the client-side and improve the performance of your application.
How does lightning data service improve user interface consistency?
Lightning Data Service also improves user interface consistency: when a component updates a record, all the other components using that record are notified, and in most cases refreshed automatically. Check out the following components in DreamHouse to see the Lightning Data Service in action: PropertyMap, PropertySummary, MortgageCalculator.
