Package Options

  • beautifyOnSave (Default false) You can also choose to beautify on every file save.

  • beautifyEntireFileOnSave (Default true) Beautification will normally only beautify your selected text. However, when beautification occurs on save then it will be forced to beautify the entire file's contents, not just selected text.

  • disabledLanguages (Default empty array) An array of Grammar names to disable beautification for. Note: If using the Atom's Package Settings then an array is represented as comma-separated string.

  • muteUnsupportedLanguageErrors (Default false) Mute only unsupported language errors.

  • muteAllErrors (Default false) Do not show the Atom Beautify Error Messages panel for any of the errors occurring while beautifying.

  • analytics (Default true) There is, which forwards the data to Google Analytics, to track what languages are being used the most and other stats. Everything is anonymized and no personal information, such as source code, is sent. See for more details.


Edit your .jsbeautifyrc file in any of the following locations:

  • Atom Package Settings
    AtomPreferences ➔ Search for atom-beautify
  • Same directory as current file
  • Project root
    atom-beautify will recursively look up from the current file's directory to find .jsbeautifyrc.
  • Your User's Home directory
