Views

Templ is the default type-safe view layer. Datastar can update fragments and consume server-sent events; Inertia v3 can render Vue, React, or Svelte pages from the same Go backend.

Templ pages

Define components under views/ and render them with pkg/hypermedia:

1templ ProductsIndex(products []models.Product) {
2    @base(SetTitle("Products")) {
3        <main><h1>Products</h1></main>
4    }
5}

Regenerate Go code after editing Templ files:

1andurel generate view

This command also compiles Tailwind utilities in email templates.

Datastar fragments

Named fragments let a controller return only changed HTML. Keep application state on the server and use signals or SSE where partial updates fit better than a full page navigation.

Inertia pages

An Inertia application owns views/root.templ and its adapter-specific files under resources/js. Pass application-facing structs or maps with stable JSON tags; do not serialize database model structs or sqlc-generated rows directly.

The v3 adapter supports partial reloads, deferred and once props, merge metadata, flash messages, redirects, asset-version reloads, and optional SSR. Configure the renderer once through Fx and inject it into controllers. See Inertia.
