W0106: A hand-written ui.HTML or ui.IslandPage

ui.HTML is what the compiler writes for a .vuka.html file's markup: the markup as a string with labelled holes, and their values. It is public so generated code builds with go build, ejected code included, but it is not a way to write markup: markup is written in .vuka.html files, whose holes the compiler checks and keeps in step with the Go. Generated files (// Code generated … DO NOT EDIT.) and ui itself aren't reported.

ui.IslandPage is what the compiler writes for an island page: a .vuka.html file whose markup is one tag, the island component its header imports. Its struct is the island's, its exported fields the props.

Wrong

// card.go
func (c Card) View() ui.Node {
	return ui.HTML(`<h2>{c.Title}</h2>`, c.Title)
}

Right

<!-- card.vuka.html -->
<script lang="go">
package components

type Card struct {
	Title string
}
</script>

<h2>{Title}</h2>

Wrong

// orders.go
func (o *Orders) Render() ui.Node { return ui.IslandPage(o) }

Right

<!-- pages/orders.vuka.html -->
<script lang="go">
package pages

import Orders "../web/islands/Orders.vue"

type Page struct {
	ui.Live
	Rows []Order `json:"rows"`

<Orders rows={Rows} client:load />
