gsxType-safe HTML that's actually pleasant to write

JSX-style markup, compiled to plain Go.

Type-safe by construction

Components lower to plain Go the compiler checks. Each component keeps its exact authored Go signature and markup binds parameters by name, so contracts stay typed and explicit.

Close to HTML, close to Go

JSX-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, v0.1.0. gsx ships tagged releases from v0.1.0; the language and APIs may still change before 1.0.
