Documentation

Read the Expressive Code docs to learn more about the features provided by Expressive Code.

When should I use this?

Using this core package directly is only recommended for advanced use cases.

Unless you're a plugin or integration author, you should probably use a higher-level package like astro-expressive-code or rehype-expressive-code instead of this one.

Installation

npm install @expressive-code/core

Usage example

import { ExpressiveCodeEngine } from '@expressive-code/core'
import { toHtml } from '@expressive-code/core/hast'

const ec = new ExpressiveCodeEngine({
  plugins: [
    // Add your plugins here
  ],
})

const baseStyles = await ec.getBaseStyles()
const themeStyles = await ec.getThemeStyles()

const renderResult = await ec.render({
  code: 'console.log("Hello world!")',
  language: 'js',
})

// Output results to the console
console.dir({
  baseStyles,
  themeStyles,
  blockStyles: renderResult.styles,
  blockHtml: toHtml(renderResult.renderedGroupAst),
})
