Principles

Stay close to HTML and Go

Use HTML-shaped markup for templates and ordinary Go for helpers, types, and application logic. The Syntax reference covers the boundary.

Prefer readable syntax

Common component code should scan like the HTML it produces. Explicit forms are available when composition or security needs more control; start with the shortest form that says what the page does. Browse the Syntax reference by task.

Let Go check the program

Components and parameters become Go declarations and calls, so go build checks names and types. See Composition.

Escape by default

Dynamic values are escaped for where they appear. Trusted-value opt-outs are explicit and narrow; use them only after validating the value. See Escaping.

Keep the runtime small

The gsx runtime uses only the Go standard library. Generation, formatting, and editor support stay in the toolchain instead of adding application dependencies.
