# Closure Linter

> **TL;DR**
> Required plugin:
>
>
>
> `JavaScript and TypeScript` -    the plugin is bundled with IntelliJ IDEA and enabled by default.
>
>
>
> `Closure Linter`:   install the plugin on the Settings | Plugins page, tab Marketplace.

> **Warning:**
> Since IntelliJ IDEA 2020.2, Closure Linter support in the IDE has been deprecated. For more information, refer to the [Closure Linter official website](https://developers.google.com/closure/utilities/).
>
>
>
> However, Closure Linter support is still available through the Closure Linter plugin, which can be installed on the Settings | Plugins page as described in [Installing plugins from JetBrains Marketplace](managing-plugins.html#install_plugin_from_repo).

When [Closure Linter support is enabled](#ws_js_linters_closure_linter_enable),  IntelliJ IDEA highlights errors that Closure Linter detects, provides descriptions for them, and suggests quick-fixes where possible.

Descriptions of the errors detected in the current file and quick-fixes for them are available from the editor and from the File tab of the [Problems](linters.html#ws_js_linters_general_problems_tool_window) tool window.

Errors in all previously opened files and quick-fixes for them are shown in the Project Errors tab of the Problems tool window. To open the tool window, click the Inspection widget in the upper-right corner of the editor:

apply quick-fixes in the editor](linters.html#ws_js_linters_editor) and [Problems tool window](linters.html#ws_js_linters_general_problems_tool_window).
