Type-safe by construction

Components lower to plain Go the compiler checks. Props use generated or user-owned structs, so contracts stay typed and explicit.

Close to HTML, close to GoJSX-style markup for templates; ordinary Go for everything else. Tag names and package-level declarations distinguish components from elements.See the syntax reference

templ-compatible

gsx.Node has the identical method set to templ.Component, so gsx output drops into the templ ecosystem without importing templ.

Status — alpha. The language and APIs may still change before a stable release.
