RubyMine 2024.1 Help


Node interpreter

In this field, specify the Node.js interpreter to use.

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

You can also choose another configured local or remote interpreter or click the Browse button and configure a new one.


In this field, specify the version of the TypeScript to use (RubyMine displays the currently chosen version).

  • By default, the typescript package from the project's node_modules folder is used.

  • Bundled: choose this option to use the typescript package that is shipped with RubyMine without attempting to find another one.

  • Select: choose this option to use a custom typescript package instead of the one bundled with RubyMine. In the dialog that opens, choose the path to the relevant package.

  • If your project package manager is Yarn 2, you have to use the typescript package installed via Yarn 2. In this case, yarn:package.json:typescript is by default selected.

    Learn more about package managers from npm and Yarn.

TypeScript Language Service

Select this checkbox to get native support from the TypeScript Language Service according to the up-to-date specifications. As a result:

  • Syntax and error highlighting is based on the annotations from the TypeScript Language Service.

  • Completion lists contain both suggestions from the TypeScript Language Service and suggestions calculated by RubyMine.

  • TypeScript code is compiled into JavaScript.



Show project errors

By default, this checkbox is selected and the TypeScript Language Service checks the code across the entire project. The detected errors are listed in the Project Errors tab of the Problems tool window grouped by files where they occurred.

To avoid performance issues, clear the Show project errors checkbox so the TypeScript Language Service checks files only when you open them. The Project Errors tab will then list the errors that are detected only in the files that you have already opened.

Show suggestions

By default, this checkbox is selected and RubyMine shows potential problems that the TypeScript Language Service detects in your code in addition to actual errors.

Show suggestions is enabled
Show suggestions is disabled

Use types from server

Select this checkbox to evaluate types of symbols based on the data from the TypeScript compiler.

By default, the checkbox is cleared so type evaluation, resolution, code inspections and refactorings are based on the type information from the RubyMine internal TypeScript engine.

This default behavior may result in performance issues and in bugs in type resolution because the type evaluation algorithm that the TypeScript Language Service uses differs from the algorithm of the TypeScript Compiler. Selecting the checkbox may help avoid these problems.

Recompile on changes

  • When this checkbox is selected, the compiler "wakes up" upon any change to a TypeScript file.

  • When this checkbox is cleared, the compiler ignores changes to TypeScript files.


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 -w or --watch (Watch input files) option is irrelevant.
