kit/theme

github.com/vormadev/vorma/kit/theme

Theme helper for server-rendered apps with light / dark / system modes.

It provides:

normalized theme data from cookies
ready-to-use HTML class string
inline script + CSP hash for system-theme flash prevention

Import

import "github.com/vormadev/vorma/kit/theme"

Quick Start

td := theme.GetThemeData(r)

Use td.HTMLClass on <html>:

<html class="{{.Theme.HTMLClass}}"></html>

Inject the system script early in <head>:

theme.SystemThemeScript()

If you use CSP, include:

theme.SystemThemeScriptSha256Hash()

Theme Values

SystemValue ("system")
LightValue ("light")
DarkValue ("dark")

GetThemeData returns:

raw user preference (Theme)
resolved concrete theme (ResolvedTheme)
opposite concrete theme (ResolvedThemeOpposite)
HTML class string (HTMLClass)

Invalid or unexpected cookie values are normalized safely:

invalid Theme -> system
invalid resolved-theme cookie -> light

Cookie names are fixed internally:

kit_theme
kit_resolved_theme

Plan integrations around those names (or wrap this package if custom names are required).
