CLion 2020.2 Help

JSHint

You can check your code with the JSHint linter which is already bundled with CLion.

When JSHint support is enabled, CLion highlights errors that JSHint detects, provides descriptions for them, and suggests quick-fixes where possible.

Error descriptions and quick-fixes are available from the editor and from the Problems tool window. To open the tool window, click the Inspection widget in the upper-right corner of the editor:

See View problems and apply quick-fixes in the editor and Problems tool window for details.

Enable JSHint and configure its behavior in CLion

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Languages and Frameworks | JavaScript | Code Quality Tools | JSHint.

  2. On the JSHint page that opens, select the Enable checkbox. After that all the controls on the page become available.

  3. In the Version field, specify the version of the tool to use. CLion comes bundled with version 2.10.2, which is used by default. To download another version, select it from the list.

  4. Configure JSHint behavior in CLion

    • Use config files - select this checkbox to apply JSHint rules from a custom configuration file, or from a .jshintrc file, or from a package.json, under the jshintConfig property.

      Select the Default option if the rules are configured in a .jshintrc file or under the jshintConfig property in a package.json. CLion will first look for such configuration in the folder where the file to be checked is stored, then in its parent folder, and so on until the filesystem root is reached.

      Alternatively, select Custom configuration file and specify the file location in the Path field below.

      Learn more about JSHint configuration files from the JSHint official website.

    • To configure verification rules manually, clear the Use config files checkbox and enable the relevant validations in the Options area. Learn more from the JSHint official website.
