What is it?

go-app lets developers build progressive web apps in Go. UI is written as reusable components that create and compose HTML elements directly in Go code, so no separate JavaScript or template language is needed on the front end. The Go code is compiled to WebAssembly to run in the browser.

The package follows the standard Go net/http model, so an app can be served through http.Handle and http.ListenAndServe like any other Go web server. Apps built with it can run in their own window, support offline mode, and are designed to be SEO friendly. Routing between components is handled with app.Route.

The project requires Go 1.18 or newer and is installed as a Go module. The documentation site at go-app.dev covers declarative syntax and a getting started guide.
