ApexPages tracking and usage

ApexPages is a server-side technology in Salesforce that allows developers to create custom, dynamic, and interactive user interfaces within the Salesforce platform. It is based on the Visualforce framework and consists of ApexPages markup and Apex Controllers, which enable you to design and develop custom pages, components, and applications for Salesforce.

ApexPages and the Lightning Component framework are both used for creating custom user interfaces in Salesforce. However, ApexPages is based on the Visualforce framework, which is an older, server-side technology, whereas the Lightning Component framework is a more modern, client-side technology built on the Aura framework. While both solutions can be used for UI development, Lightning is more suited for creating responsive and mobile-friendly applications and is generally recommended for new projects.

Yes, you can use ApexPages with Salesforce Lightning Experience. However, you may need to make some adjustments to your Visualforce pages to ensure they are compatible and render correctly within the Lightning Experience. This may involve adding Lightning Stylesheets or wrapping your existing Visualforce pages with the "lightning:container" component.

You can access records and fields in ApexPages using standard and custom controllers. Standard controllers provide basic functionalities and are automatically available when you reference an object in your Visualforce page. Custom controllers enable advanced functionalities and need to be written in Apex code, which can then be associated with your Visualforce page. Both standard and custom controllers allow you to query, create, edit, and delete records within the Salesforce platform.

Custom components in ApexPages can be created using the Developer Console or your preferred IDE. Once created, these components can be reused across different Visualforce pages to maintain consistent functionality and appearance.
