PhpStorm shows this tool window only when the TypeScript Language Service is activated on the TypeScript page as described in TypeScript. Use this tool window to view the errors detected by the TypeScript Language Service and the built-in TypeScript compiler.
Errors
The tab lists the discrepancies in the code detected by the TypeScript Language Service. The list is updated dynamically as you change your code.
By default, the list contains only the errors from the file in the active editor tab and the full path to this file is displayed at the top. To show the errors across the entire project, press the Show project errors toggle button on the toolbar. The tab shows error messages 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 on the context menu.
Compile Errors
The tab lists the errors that occurred during compilation.
PhpStorm updates the list as soon as your code is recompiled. If the Recompile on changes checkbox on the TypeScript page is selected, the list is updated as you edit your code. To change this setting, clear the Recompile on changes checkbox.
By default, the list contains only the errors from the file in the active editor tab. To view the compilation errors across the entire compilation scope, click on the toolbar and choose Compile All from the list. The error messages are shown grouped by files in which they were detected.
