JS-Beautify for VS Code

VS Code uses js-beautify internally, but it lacks the ability to modify the style you wish to use.

This extension enables running js-beautify in VS Code,

AND honouring any .jsbeautifyrc file in the open file's path tree to load your code styling.

Run with F1 Beautify selection (to beautify a selection) or F1 Beautify file.

For help on the settings in the .jsbeautifyrc see SETTINGS.md.

How we determine what settings to use

1. When not using a multi-root workspace:

   1. If there is a valid .jsbeautifyrc in the file's path tree, up to project root, these will be the only settings used.
   2. If an option is a file path or object of configuration specified in the user or workspace settings like this: "beautify.config" : "string|Object.<string,string|number|boolean>", these will be the only settings used. The file path is interpreted relative to the workspace's root folder.
   3. If there is a valid .jsbeautifyrc in the file's path tree, above project root, these will be the only settings used.
   4. If there is a valid .jsbeautifyrc in your home directory, these will be the only settings used.

2. When using a multi-root workspace: Same as above, but the search ends at the nearest parent workspace root to the open file.

otherwise...

3. Settings are translated from your VS Code workspace/user settings.
4. Any open editor settings (indent spaces/tabs) for the specific file are merged in.
5. Editorconfig settings are searched for (See http://editorconfig.org/) and are merged in.

VS Code | .jsbeautifyrc settings map

.jsbeautifyrc setting	VS Code setting
eol	files.eol
tab_size	editor.tabSize
indent_with_tabs (inverted)	editor.insertSpaces
wrap_line_length	html.format.wrapLineLength
wrap_attributes	html.format.wrapAttributes
unformatted	html.format.unformatted
indent_inner_html	html.format.indentInnerHtml
preserve_newlines	html.format.preserveNewLines
max_preserve_newlines	html.format.maxPreserveNewLines
indent_handlebars	html.format.indentHandlebars
end_with_newline	html.format.endWithNewline (html)
end_with_newline	files.insertFinalNewline (css, js)
extra_liners	html.format.extraLiners
space_after_anon_function	javascript.format .insertSpaceAfterFunctionKeywordForAnonymousFunctions
space_in_paren	javascript.format .insertSpaceAfterOpeningAndBeforeClosingNonemptyParenthesis

Note that the html.format settings will ONLY be used when the document is html. javascript.format settings are included always.

Also runs html and css beautify from the same package, as determined by the file extension. The schema indicates which beautifier each of the settings pertains to.

The .jsbeautifyrc config parser accepts sub elements of html, js and css so that different settings can be used for each of the beautifiers (like sublime allows). Note that this will cause the config file to be incorrectly structured for running js-beautify from the command line.

Settings are inherited from the base of the file. Thus:

{
  "indent_size": 4,
  "indent_char": " ",
  "css": {
    "indent_size": 2
  }
}

Will result in the indent_size being set to 4 for JavaScript and HTML, but set to 2 for CSS. All will get the same indent_char setting.

If the file is unsaved, or the type is undetermined, you'll be prompted for which beautifier to use.

You can control which file types, extensions, or specific file names should be beautified with the beautify.language setting.

{
  "beautify.language": {
    "js": {
      "type": ["javascript", "json"],
      "filename": [".jshintrc", ".jsbeautifyrc"]
      // "ext": ["js", "json"]
      // ^^ to set extensions to be beautified using the javascript beautifier
    },
    "css": ["css", "scss"],
    "html": ["htm", "html"]
    // ^^ providing just an array sets the VS Code file type
  }
}

Beautify on save will be enabled when "editor.formatOnSave" is true.

Beautification on particular files using the built in Format Document (which includes formatting on save) can be skipped with the beautify.ignore option. Using the Beautify file and Beautify selection will still work. For files opened from within the workspace directory, the glob patterns will match from the workspace folder root. For files opened from elsewhere, or when no workspace is open, the patterns will match from the system root.

Examples:

/* ignore all files named 'test.js' not in the root folder,
   all files directly in any 'spec' directory, and
   all files in any 'test' directory at any depth
*/
"beautify.ignore": ["*/test.js", "**/spec/*", "**/test/**/*"]

/* ignore all files ending in '_test.js' anywhere */
"beautify.ignore": "**/*_test.js"

Note that the glob patterns are not used to test against the containing folder. You must match the filename as well.

Embedded version of js-beautify is v1.8.4

Keyboard Shortcut

Use the following to embed a beautify shortcut in keybindings.json. Replace with your preferred key bindings.

{
  "key": "cmd+b",
  "command": "beautify.beautifySelection",
  "when": "editorFocus"
}
