Introducing Edge Slice Rerendering
summary
A new technique called Edge Slice Re-rendering (ESR) combines static analysis with CDN edge compute to extract minimal program slices (for example only running toUpperCase for a headline) and apply overrides as diffs to statically generated pages. A demo on the Next.js docs banner on a 4G Moto shows ESR (Outsmartly) slightly beating the SSG baseline, matching SSR latency, and avoiding the client-side flash where a popular third-party tool briefly reverts content. The system runs slices at the edge, supports async compute and caching.
