This means introducing a component tag and the ability to create components that can SSR and CSR as well.
Some requirements are

• easy to use
• no needed logic to fetch data from the server. These components should already have the inherent context data
• use Web Components behind the scene
• no lifecycle hooks. The component should update automatically when data changes
• allow data transformation pipes so data can be transformed before being used in updates
• allow tags and components to have a dedicated style that the app imports on load
• compile returned tag markup
• component relies on template
