IntelliJ IDEA 2020.3 Help

TypeScript tool window

This tool window lists compilation errors in TypeScript code. This list is not affected by changes you make to your code and is updated only when you invoke compilation again.

IntelliJ IDEA shows this tool window only when the TypeScript Language Service is activated on the TypeScript page as described in TypeScript.

The tool window shows up only after you first compile your TypeScript code manually. After that the tool window is accessible via View | Tool Windows | TypeScript on the main menu or via the tool window bar.

See Compiling TypeScript into JavaScript.

Compile Errors

The tool window shows up only after you first compile your TypeScript code manually. This can be done in two ways:

  • Click the TypeScript widget on the Status bar, select Compile, and then select the compilation scope.

    By default, Compile All stands for Compile all TypeScript files in the whole project. To change this behavior, define another scope under the files property of your tsconfig.json file. Type the names of the files to process in the following format:

    "files" : ["<file1.ts>","<file2.ts>"],

  • Select Compile TypeScript from the context menu of any TypeScript file. All the TypeScript files in the default scope will be compiled, as when you select Compile All from the TypeScript widget,

After that the tool window is accessible via View | Tool Windows | TypeScript on the main menu or via the tool window bar.

The tool window lists all the compilation errors detected in the chosen scope. This list is not affected by changes you make to your code and is updated only when you invoke compilation manually again.

Error messages are grouped by files in which they were detected. To navigate to the code in question, double-click the corresponding error message or select it and choose Jump to Source from the context menu.

ItemDescription
Compile

Select this option to invoke manual TypeScript compilation and then select the range of files to compile.

  • To compile the file in the active editor tab, choose the path to the file.

  • To use the scope defined in a tsconfig.json file, choose the path to the required tsconfig.json.

  • If you select Compile All, by default, the compiler runs in the whole project. To change this behavior, define another scope under the files property of your tsconfig.json file. Type the names of the files to process in the following format:

    "files" : ["<file1.ts>","<file2.ts>"],
