@sanity/code-input

Code input for Sanity.

Currently only a subset of languages and features are exposed, over time we will implement a richer set of options.

Installation

sanity install @sanity/code-input

Usage

Use it in your schema types:

// [...]
{
  fields: [
    // [...]
    {
      name: 'exampleUsage',
      title: 'Example usage',
      type: 'code',
    },
  ]
}

Note that the above only works if you import and use the all:part:@sanity/base/schema-type part in your schema.

Options

  • language - Default language for this code field
  • languageAlternatives - Array of languages that should be available (se its format in the example below)
  • theme - Name of the theme to use.
    • Possible values include: ['github', 'monokai', 'terminal', 'tomorrow'].
    • For the full list and a live playground, refer to the react-ace page.
  • withFilename - Boolean option to display input field for filename
// ...fields...
{
  name: 'exampleUsage',
  title: 'Example usage',
  type: 'code',
  options: {
    theme: 'solarized_dark',
    language: 'js',
    languageAlternatives: [
      {title: 'Javascript', value: 'js'},
      {title: 'HTML', value: 'html'},
      {title: 'CSS', value: 'css'},
      {title: 'Rust', value: 'rust', mode:'rust'},
      {title: 'SASS', value: 'sass'},
    ]
  }
}

Add support for more languages

Only a subset of languages are supported by default (see full list here). You can add support for other languages by importing the ace mode yourself, and specifying mode for the languageAlternatives schema config.

Example: Add support for the Rust Programming Language

// import rust support for ace, see https://github.com/securingsincity/react-ace for more details
import 'ace-builds/src-noconflict/mode-rust'

{
    name: 'exampleUsage',
    title: 'Example usage',
    type: 'code',
    options: {
      languageAlternatives: [
        {title: 'Javascript', value: 'js'},
        {
          title: 'Rust',
          value: 'rust',
          mode:'rust' // <- specify the mode to use here. Make sure this mode is also imported from ace-builds (see above)
        },
     ]
  }
}

Data model

{
  _type: 'code',
  language: 'js',
  highlightedLines: [1, 2],
  code: 'const foo = "bar"\nconsole.log(foo.toUpperCase())\n// BAR'
}

Example usage in frontend (React)

You can use any syntax highlighter you want - but not all of them might support highlighted lines or the syntax you've defined.

As outlined above, the actual code is stored in a code property, so if your schema has a field called codeExample of type code, the property you'd want to pass to the highlighter would be codeExample.code.

Here's an example using react-refractor:

import React from 'react'
import Refractor from 'react-refractor'
import js from 'refractor/lang/javascript'

Refractor.registerLanguage(js)

export function Code(props) {
  return (
    <Refractor
      // In this example, `props` is the value of a `code` field
      language={props.language}
      value={props.code}
      markers={props.highlightedLines}
    />
  )
}

export default Code
