Make Web UI Easy with Leptos
summary
Leptos builds full‑stack Rust web UIs with WebAssembly and a fine‑grain reactive model that updates only the changed bits of the page. It supports client rendering and server rendering with hydration so initial loads avoid post‑wasm data fetches, uses server functions create API endpoints to call Rust on the server from the client, and shows a real e‑commerce site of 31,000 products. Example builds include a Hacker News clone with a 650 KB wasm bundle and benchmarks showing 10x higher throughput vs Remix under load. Compile increments run in ~2s.
