# Language Modules

# Language Modules

Every bundled language is an isolated [`LanguageDefinition`](core#languagedefinition). Import exactly the registrations needed by your application.

```ts
import { createHighlighter } from '@tanstack/highlight/core'
import { plaintext } from '@tanstack/highlight/languages/plaintext'
import { tsx } from '@tanstack/highlight/languages/tsx'

const highlighter = createHighlighter({
  fallbackLanguage: 'plaintext',
  languages: [plaintext, tsx],
})
```

The barrel is convenient but individual subpaths make bundle intent explicit.

See the [language support matrix](../language-support) for the context-aware behavior and current scope of each registration.
