After installing TypeScript community stubs, WebStorm is unable to locate the module

Recently, I tried to incorporate the ramda library into my project and went ahead to install its TypeScript community stubs in WebStorm.

Despite my efforts, I encountered an error that stated —

Cannot find module 'ramda'.

I am aware of a potential solution using the typings module. However, this makes me wonder about the purpose of installing the stubs via WebStorm initially.

Answer №1

WebStorm utilizes libraries configured in

Settings | Languages & Frameworks | JavaScript | Libraries
solely for code completion and navigation purposes, but they are not accessible to the TypeScript compiler.

When Typescript stubs are downloaded through

Settings | Languages & Frameworks | JavaScript | Libraries
, they are stored in
<webStorm configuration directory>/javascript/extLibs/
. WebStorm does not require these library files to be placed directly in the project folder, as their primary function is to enable the use of external files for code completion without cluttering the project directory. However, the tsc compiler requires the d.ts files to be located within the project directory and referenced using ///<reference> comments or import statements.

To make the downloaded stubs accessible to the typescript compiler, it is necessary to copy or move them to your project directory (and possibly rename them for better readability). This will make them available to both WebStorm and the compiler.

We are considering adding an option to download files directly to the project folder (instead of system/extLibs/) in future releases - refer to WEB-9237 and linked tickets for updates.
