ESLint

This feature is supported in the Ultimate edition only.

Use this page to enable the JavaScript ESLint code verifier and to configure its behaviour. If you are using JavaScript Standard Style in your project, you can enable linting with it here.

To configure IntelliJ IDEA code style options for JavaScript to follow the main rules Standard declares so they are applied when you type the code or reformat it, open the Code Style. JavaScript page (File | Settings | Editor | Code Style | JavaScript for Windows and Linux or IntelliJ IDEA | Preferences | Editor | Code Style | JavaScript for macOS), click Set from, and then choose Predefined Style | JavaScript Standard Style. The style will replace your current scheme.

Item	Description
Enable	Select this check box to have ESLint/Standard 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. If you have appointed one of the installations as default, the field displays the path to its executable file.
ESLint Package	In this field, specify the location of the `eslint` package installed in the current project, see Installing ESLint or the `standard` package installed in your project or globally, see Installing JavaScript Standard.
Configuration file	In this area, appoint the configuration to use. By default, IntelliJ IDEA first looks for a `.eslintrc` configuration file. IntelliJ IDEA 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 `.eslintrc` file is found, ESLint uses its default embedded configuration file. Accordingly, you have to define the configuration to apply either in a `.eslintrc` configuration file, or in a custom JSON configuration file, or rely on the default embedded configuration. To have IntelliJ IDEA look for a `.eslintrc` file, choose the Search for .eslintrc option. If no `.eslintrc` 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 `.eslintrc` or the above specified custom configuration file and accordingly will override them.
Extra ESLint Options	In this field, specify additional command line options to run ESLint with using spaces as separators. See ESLint Command Line Interface Options for details.
