IntelliJ IDEA 2019.2 Help

JSLint

IntelliJ IDEA lets you verify your JavaScript code using the built-in JSLint tool. Note that JSLint does not fully support the latest ECMAScript features.

To enable JSLint and configure its behavior in IntelliJ IDEA

  1. In the Settings/Preferences dialog (Ctrl+Alt+S), go to Languages and Frameworks | JavaScript | Code Quality Tools | JSLint, and select the Enable checkbox. After that the other controls on the page become available.

  2. In the Tolerate area, specify the types of problems you do not want JSLint to report. By default, the tool reports detected problems of all types. To skip problems of a certain type, select the checkbox next to this type.

    Learn more about JSLint options from the JSLint official website.

  3. In the Assume area, specify the targeted environment to check the code for.

  4. Specify the maximum number of problems to report maxerr, the maximum line length maxlen, and the predefined global variables by names or through object keys predef.

  5. Select the JSON checkbox in the Validate also area to verify .json files as well.
