RubyMine 2023.3 Help

Auto-import

In JavaScript and TypeScript files, RubyMine automatically adds import statements for modules, classes, components, and any other symbols that can be exported, as well as for XML namespaces. Learn more from Auto-import in JavaScript, Auto-import in TypeScript and Importing an XML namespace.

When you complete a ES6 symbol or a CommonJS module, RubyMine either decides on the style of the import statement itself or displays a popup where you can choose the style you need. Learn more from Auto-import in JavaScript.

Add import statements on code completion

RubyMine adds import statements when you complete exported JavaScript or TypeScript symbols.

Add ES6 imports on code completion

You can disable auto-import on completion and use quick-fixes instead:

  1. In the Settings dialog (Control+Alt+S), go to Editor | General | Auto Import.

  2. On the Auto Import page that opens, use the checkboxes in the TypeScript/JavaScript area to enable or disable import generation on code completion.

Use a quick-fix

For JavaScript symbols from your project dependencies, RubyMine has a quick-fix for adding import statements when they are missing or when auto-import is disabled.

RubyMine marks the symbol as unresolved and shows a tooltip with the suggested quick-fix:

ws_es6_autoimport_off_tooltip.png

Alternatively, press Alt+Enter:

ws_es6_autoimport_off.png

If there's more than one possible source of import, RubyMine shows a list of suggestions:

Autoimport with quick-fix: multiple choices

If you don't want to see Missing import statement warnings, disable the inspection in the current file or in the entire project. For more information, refer to Disabling and enabling inspections.

Disable Missing import statement inspection

Alternatively, change highlighting level for the file: hover over the widget in the top-right corner of the editor and select None or Syntax from the Highlight list.

Add import statements using the auto-import tooltip

In TypeScript, RubyMine shows you an auto-import tooltip. To accept the suggestion, press Alt+Enter.

Add import statements using the auto-import tooltip

To disable the popup, hover over the inspection widget in the top-right corner of the editor, click More, and clear the Show Auto-Import Tooltip option.

Optimize imports

RubyMine helps you remove unused imports and organize import statements in the current file, in all files in a directory, or in the entire project at once.

Optimize all imports

  1. Select a file or a directory in the Project tool window (View | Tool Windows | Project).

  2. Do any of the following:

    • Go to Code | Optimize Imports (or press Control+Alt+O).

    • From the context menu, select Optimize Imports.

  3. (If you've selected a directory) Choose whether you want to optimize imports in all files in the directory, or only in locally modified files (if your project is under version control), and click Run.

Optimize imports in a single file

  • Place the caret at an import statement and press Alt+Enter or use the the Intention action button icon. Then select Remove unused 'import'.

    Remove unused import
  • Open the file in the editor or select it in the Project tool window and press Control+Alt+O.

Optimize imports when reformatting a file

You can tell RubyMine to optimize imports in a file every time it is reformatted.

  • Open the file in the editor, press Control+Alt+Shift+L, and make sure the Optimize imports checkbox is selected in the Reformat File dialog that opens.

After that every time you press Control+Alt+L in this project, RubyMine will optimize its imports automatically.

Optimize imports before committing changes to your VCS

If your project is under version control, you can instruct RubyMine to optimize imports in modified files before committing them to VCS.

  • In the Commit tool window Alt+0, click Show Commit Options and select the >Optimize imports checkbox in the Commit checks area.

    Optimize imports before commit
  • You can also optimize imports only in the updated code. In the Project tool window, select a folder, and pressControl+Alt+O. In the Optimize imports dialog, select the Process only VCS changed files and click Run.

Automatically optimize imports on save

You can configure the IDE to optimize imports in modified files automatically when your changes are saved.

  1. Press Control+Alt+S to open the IDE settings and then select Tools | Actions on Save.

  2. Enable the Optimize imports option and apply the changes.

    Additionally, from the All file types list, select the types of files in which you want to use automatic import optimization.
