In this dialog, activate, deactivate, and configure the behaviour of the built-in TypeScript compiler that compiles TypeScript code into JavaScript so the code can be executed in a browser and generates sources maps that ensure correspondence between the lines in the generated JavaScript code and the lines in the original TypeScript code.

Node interpreter In this field, specify the location of the Node.js executable file. In most cases, CLion detects the Node.js executable and fills in the field automatically.
TypeScript version In this area, specify the version of the compiler to use (CLion displays the currently chosen version):
  1. Click Edit.
  2. In the Configure TypeScript Compiler dialog box that opens, choose one of the following options:
    • Detect: if you choose this option, CLion searches for a typescript package in the current project. If a typescript package is found, CLion uses it. Otherwise the default bundled package is used. This option is chosen by default.
    • Bundled: if you choose this option, CLion uses it without attempting to find another typescript package.
    • Custom directory: choose this option to use a custom version of the compiler. In the text box, specify the location of the typescriptServices.js, lib.d.ts, and lib.es6.d.ts files downloaded from
Use TypeScript Service Select this check box to get native support from the TypeScript Language Service according to the up-to-date specifications. In this case, syntax and error highlighting is performed based on the annotations retrieved from the TypeScript Language Service while code completion lists contain both suggestions from the TypeScript Language Service and suggestions calculated by CLion itself. To get only suggestions from CLion, click Configure and clear the Code completion check box in the Service Options dialog box that opens.

CLion supports integration with the Angular language service developed by the Angular team to improve code analysis and completion for Angular-TypeScript projects. Note that the Angular language service works only with the projects that use Angular 2.3.1 or higher and TypeScript version compatible with it. The Angular language service is activated by default so CLion starts it automatically together with the TypeScript service and shows all the errors and warnings in your TypeScript and HTML files both in the editor and in the TypeScript Compiler Tool Window. However if you still need to activate the service, click Configure and select the Use Angular service check box in the Service Options dialog box that opens.

By default, the Use TypeScript Service check box is selected.

In the Default options field, specify the command line options to be passed to the compiler when the tsconfig.json file is not found. See the list of acceptable options at TSC arguments. Note that, the -w or --watch option (Watch input files) is irrelevant.

Enable TypeScript Compiler Select this check box to activate the built-in compiler. When the check box is selected, syntax highlighting and code completion are provided based only on the data from the built-in Typescript compiler. After you select this check box, the fields below in the area become active and you can configure the behaviour of the compiler. By default, the check box is cleared.
Track changes
  • When this check box is selected, the built-in compiler "wakes up" upon any change to a TypeScript file.
  • When this check box is cleared, the built-in compiler ignores changes to TypeScript files. To re-activate the compiler, open the TypeScript Compiler Tool Window (View | Tool Windows | TypeScript Compiler), and click the Compile All button icon_ts_compile_all on the toolbar.

    If you have not opened the TypeScript Compiler Tool Window yet and it is not available from the View menu, choose Help | Find Action, then find and launch the TypeScript Compile All action from the list.

Scope From this drop-down list, choose the scope to apply the compiler in. The available options are:
  • Project Files: all the files within the project roots.
  • Open Files: all the files that are currently opened in the editor.
Alternatively, click the Browse button and configure a custom scope in the Scopes dialog box that opens. For more details on scopes, see Scopes dialog.
Use tsconfig.json Choose this option to have the built-in compiler analyze the code according to the settings specified in the tsconfig.json file. When you open a project, CLion starts searching for a tsconfig.json file in it. If a tsconfig.json file is found, the compiler uses the options specified in it. Otherwise an error is reported.
Set options manually Choose this option to configure the behaviour of the built-in compiler manually:
  • Select the Generate source maps check box to generate source maps that set correspondence between lines in your TypeScript code and in the generated JavaScript code, otherwise your breakpoints will not be recognised and processed correctly.
  • Select the Compile main file only check box to have CLion compile only a specific file and the files that are referenced from it and ignore all the other files in the project. This may be helpful if you have a dedicated main.ts file which only references other files.
  • Select the Use output path check box to have the built-in compiler store the generated JavaScript files and source map in a custom folder. Specify the path to this folder explicitly or use one of the listed available macros in the format: $<macros_name>$. The available macros are:
    • FileDir: the path to the folder where the file is stored.
    • FileRelativeDir: the path to the file directory relative to the project root.
    • FileDirRelativeToProjectRoot: the path to the file directory relative to the project root.
    • ModuleFileDir: the path to the project root folder.
    • SourcePath: the path to the project root folder.
    • FileDirRelativeToSourcePath: the path to the file relative to the source folder under the content root to the file belongs.
