In this dialog:

  • Choose whether you want to use the TypeScript Language Service or to get coding assistance from JetBrains Rider only.
  • Activate, deactivate, and configure the behaviour of the built-in TypeScript compiler.

ItemDescription
Node interpreter In this field, specify the location of the Node.js executable file. In most cases, JetBrains Rider detects the Node.js executable and fills in the field automatically.
TypeScript version In this area, specify the version of the compiler to use (JetBrains Rider 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, JetBrains Rider searches for a typescript package in the current project. If a typescript package is found, JetBrains Rider uses it. Otherwise the default bundled package is used. This option is chosen by default.
    • Bundled: if you choose this option, JetBrains Rider 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 https://github.com/Microsoft/TypeScript/.
Use TypeScript Service Select this check box 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 JetBrains Rider. To get only suggestions from JetBrains Rider, click Configure and clear the Code completion checkbox in the Service Options dialog that opens.

JetBrains Rider 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 JetBrains Rider 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 TypeScirpt Compiler window. However if you still need to activate the service, select the Angular Language Service checkbox.

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 (Watch input files) option is irrelevant.

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

Enable TypeScript Compiler Select this check box to activate the built-in compiler. When the checkbox is selected, syntax highlighting and code completion are provided based only on the data from the built-in TypeScript compiler. After you select this checkbox, the fields below in the area become active and you can configure the behaviour of the compiler. By default, the checkbox 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 checkbox is cleared, the built-in compiler ignores changes to TypeScript files. To re-activate the compiler, open the TypeScirpt Compiler 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.
  • 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.
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, JetBrains Rider 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 JetBrains Rider 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.
