gsxHTML as a first-class Go value

templ-style components, JSX-style markup, compiled to plain Go. A standard-library-only runtime.

Type-safe by construction

Components lower to plain Go the compiler checks. Props are generated structs — gsx owns the field names, so there is no symbol-resolver guesswork.

Close to HTML, close to Go

JSX-style markup for templates; ordinary Go for everything else. Capitalization decides component-vs-element.

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. gsx is runnable end-to-end: gsx generate compiles .gsx → .x.go (plus gsx fmt and gsx info). Codegen covers interpolation, control flow, attributes with contextual escaping, the |> pipeline + filters, components/props/{children}, method components, named slots, and attribute fallthrough. Still in progress: some CLI commands (vet/lsp), style composition, and structured diagnostics.
