Insert imports on pasteUse this drop-down list to define how IntelliJ IDEA will insert imports for pasted blocks of code, if they contain references to classes that are not imported into the target class.

The available options are:

  • All - select this option to have IntelliJ IDEA automatically add import statements for all classes that are found in the pasted block of code and are not imported in the current class yet.
  • Ask - if this option is selected, when pasting code blocks, IntelliJ IDEA will open a dialog box, where you can choose the desired imports.
  • None - select this option to suppress import.

If you skip an import suggested in the Ask mode or choose the None mode, the non-imported classes will be red-highlighted and an import pop-up window will appear to help you create import statements using the ⌥⏎ or ⌥⏎⌥⏎ or ⌥⏎⌘1 or ⌘1⌥ Enter, ⌥⏎ or ⌥⏎⌥ Enter, ⌥⏎ or ⌥⏎ keyboard shortcut.

Merge imports for symbols from the same module
Use paths relative to tsconfig.json When this check box is selected, IntelliJ IDEA calculates import paths using the tsconfig.json file as the root. When this check box is cleared, IntelliJ IDEA calculates import paths relative to the project root.

For example, if your project is structured as follows:

ws_ts_import_example.png

With the check box selected, IntelliJ IDEA generates the following import statement: 
import {ClassName} from 'directory_2/file_2'
If the check box is cleared, the following import statement is generated: 
import {ClassName} from '../directory_2/file_2'
