Type: Post

The article explores strategies for caching Liveviews in Phoenix applications, particularly focusing on scenarios where parts of a page are private but can still benefit from caching. It introduces the concept of partially caching private Liveviews by having the initial page render public content, while only rendering user-specific details during the live mount phase. Several existing approaches, such as altering cache keys based on user roles and utilizing Edge-Side Includes (ESI), are examined. The author proposes a new pattern that allows for caching the public parts of a page while deferring user-specific information for later rendering. This method emphasizes designing pages to prevent layout shifts and ensuring private data is protected from unintended caching. The article concludes by outlining best practices and considerations for implementing this caching strategy effectively within Phoenix applications.
