Partial DOM Hydration: Angular's Most Requested Feature
summary
A 2016 feature request for Partial DOM Hydration finally yields concrete outcomes: Angular integrates hydration primitives into Angular Universal after seven years of work, enabling non-destructive hydration (server-rendered HTML attaches to serialized component state instead of being re-rendered). Early hacks like pancakes and preboot proved concepts but required intrusive core changes; Ivy and subsequent internals make the approach feasible and parts are landing toward version 16, with progressive hydration planned later and initial tests showing it works.
