In this dialog, activate, deactivate, and configure the behaviour of the built-in TypeScript compiler that transpiles 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.

ItemDescription
Node interpreter In this field, specify the location of the Node.js executable file. In most cases, IntelliJ IDEA detects the Node.js executable and fills in the field automatically.
TypeScript version In this area, specify the version of the compiler to use. IntelliJ IDEA displays the default bundled version.

To use a custom version of the compiler:

  1. Download the typescriptServices.js, lib.d.ts, and lib.es6.d.ts files from https://github.com/Microsoft/TypeScript/.
  2. Click Edit in the Compiler version area.
  3. In the Configure TypeScript Compiler dialog box that opens, choose Custom directory and specify the folder where the downloaded files are stored.

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 IntelliJ IDEA itself.
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 on the page become active and you can configure the behaviour of the compiler.
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 content roots (see Content Root and Configuring Content Roots).
  • Project Production Files: all the files within the project content roots excluding test sources.
  • Project Test Files: all the files within the project test source roots.
  • Open Files: all the files that are currently opened in the editor.

VCS Scopes: these scopes are only available if your project is under version control.

  • Changed Files: all changed files, that is, all files associated with all existing changelists.
  • Default: all the files associated with the changelist Default.
Alternatively, click the Browse button and configure a custom scope in the Scopes dialog box that opens. For more details on scopes, see the pages Scopes and Scopes dialog.
Set options manually Choose this option to configure the behaviour of the built-in compiler manually:
  • In Command line options field, specify the command line options to be passed to the compiler. See the list of acceptable options at TSC arguments. Note that, the -w or --watch option (Watch input files) is irrelevant.
  • 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 IntelliJ IDEA 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 module content root the file belongs to.
    • ModuleFileDir: the path to the module root folder.
    • SourcePath: the path to the source folder under the content root to which the file belongs, see Configuring Content Roots and Configuring Folders Within a Content Root.
    • FileDirRelativeToSourcePath: the path to the file relative to the source folder under the content root to the file belongs.
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 .
