In this field, specify the Node.js interpreter to use.
If you choose the Project alias, WebStorm will automatically use the project default interpreter from the Node interpreter field on the Node.js page . In most cases, WebStorm detects the project default interpreter and fills in the field itself.

See Configuring remote Node.js interpreters, Configuring a local Node.js interpreter, and Using Node.js on Windows Subsystem for Linux for details.

If your project package manager is Yarn 2, you have to use the
typescriptpackage installed via Yarn 2. In this case,

Recompile on changes
In this field, specify the command-line options to be passed to the TypeScript Language Service when the tsconfig.json file is not found. See the list of acceptable options at TSC arguments. Note that the
