Language Modules#

Every bundled language is an isolated LanguageDefinition. Import exactly the registrations needed by your application.

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],
})

Individual exports#

@tanstack/highlight/languages re-exports apache, css, diff, dockerfile, ejs, env, html, http, js, json, jsx, markdown, mermaid, nginx, plaintext, python, scheme, shell, sql, svelte, toml, ts, tsrx, tsx, vue, and yaml. The barrel is convenient but individual subpaths make bundle intent explicit.

See the language support matrix for the context-aware behavior and current scope of each registration.
