Item	Description
Enable	Select this check box to have TSLint applied to verify the code in the current project. After that the other controls in the page are enabled.
Node Interpreter	In this field, specify the NodeJS installation home. Type the path to the NodeJS executable file manually, or click the button and select the location in the dialog box, that opens.
TSLint Package	In this field, specify the location of the tslint package installed globally or in the current project, see Using TSLint Code Quality Tool.
Configuration File	In this area, appoint the configuration to use. By default, WebStorm first looks for a tslint.json configuration file. WebStorm starts the search from the folder where the file to be checked is stored, then searches in the parent folder, and so on until reaches the project root. If no tslint.json file is found, TSLint uses its default embedded configuration file. Accordingly, you have to define the configuration to apply either in a tslint.json configuration file, or in a custom JSON configuration file, or rely on the default embedded configuration. To have WebStorm look for a tslint.json file, choose the Search for tslint.json option. If no tslint.json file is found, the default embedded configuration file will be used. To use a custom file, choose the Configuration File option and specify the location fo the file in the Path field. Choose the path from the drop-down list, or type it manually, or click the button and select the relevant file from the dialog box that opens.
Additional Rules Directory	In this field, specify the location of the files with additional code verification rules. These rules will be applied after the rules from tslint.json or the above specified custom configuration file and accordingly will override them.
