Usage

This page covers practical patterns for using TanStack Head Controller in real apps.

Baseline integration

1. Place the controller in router context (for example, thc)
2. Return head from routes
3. Place the render component (HeadController) in the root document head

Combine plugins

import { createHeadController } from '@thcjs/core'
import { thcMerge } from 'thc-plugin-merge'

export const thc = createHeadController({
  plugins: [
    thcMerge(),
  ],
})

If you are using Solid, replace @thcjs/react with @thcjs/solid in the render step.

Edit route context

Use the helper (editContext) to merge controller-specific values while preserving existing route context.

about.tsx

import { editContext } from '@thcjs/core/context'

export const Route = createFileRoute('/about')({
  context: (ctx) =>
    editContext(ctx, {
      configs: {
        debug: true,
      },
    }),
})

Write a custom plugin

import { createThcPlugin } from '@thcjs/core/plugins'

export const forceNoIndex = () =>
  createThcPlugin({
    name: 'app.force-noindex',
    transform(head) {
      return {
        ...head,
        meta: [...(head.meta ?? []), { name: 'robots', content: 'noindex' }],
      }
    },
  })

Ordering guidance

• Plugins run in registration order
• Put normalization plugins first and final formatting plugins later

Common production patterns

• Define base metadata at layout level and override it at page level
• Standardize OG tags with one plugin
• Centralize environment-based robots behavior with a plugin
