Disable JavaScript import optimization for a specific file in IntelliJIDEA

I recently came across a tutorial on Angular 2 Google maps that I was following:

The tutorial included the following import statement:

import { } from 'googlemaps';

However, I encountered a problem where IntelliJ recognized this as an empty import and would delete it every time I reformatted the file. To work around this issue, I had to disable the "optimize import" option globally, which is not ideal as I may want to use it in other files. I tried adding comments to ignore formatting for that specific line of code like so:

//@formatter:off    
import { } from 'googlemaps';
//@formatter:on

Unfortunately, even with these comments, IntelliJ continued to remove the import statement upon reformatting. Does anyone have any suggestions on how to resolve this?

Answer №1

Typically, the TypeScript compiler behaves in a way that eliminates unused imports, but you can avoid this by utilizing a specific syntax on an import statement:

// This import won't be optimized away by the TypeScript compiler
import 'googlemaps';

By including this syntax, you prevent the compiler from discarding seemingly unused imports.

I'm optimistic that IntelliJ employs a similar approach when dealing with this type of coding style.
