SEO Plugin

The SEO plugin manages the document <title> and <meta> tags. Use it when you want your rfw app to update these values dynamically, without manually touching the DOM.

Features

Set the document title with a pattern (%s | rfw, etc.).
Add or update <meta> tags (e.g. description).
Automatically creates missing <title> or <meta> elements.

Setup

Enable the plugin in rfw.json:

{
  "plugins": {
    "seo": {
      "title": "rfw",
      "pattern": "%s | rfw",
      "meta": {
        "description": "rfw documentation"
      }
    }
  }
}

import "github.com/rfwlab/rfw/v2/core"
import "github.com/rfwlab/rfw/v2/plugins/seo"

func init() {
    core.RegisterPlugin(seo.New())
}

Usage

Update values at runtime:

seo.SetTitle("About")
seo.SetMeta("description", "Page description")

API Reference

Function	Description
`seo.SetTitle(title string)`	Updates the `<title>` element. Applies the configured `pattern`.
`seo.SetMeta(name, content string)`	Updates or creates a `<meta name="...">` element.

Example

p := seo.New()
_ = p.Build([]byte(`{"title":"rfw","pattern":"%s | rfw"}`))
p.Install(nil)
seo.SetTitle("Docs")
seo.SetMeta("description", "rfw documentation")

Notes

The pattern must contain a %s placeholder; it is passed to fmt.Sprintf.
SetTitle and SetMeta can be reassigned before core.RegisterPlugin to customize behavior.
Missing <title> or <meta> tags will be created automatically.
