 * [Custom Locator Strategies](#custom-locators): by data attributes or whatever you prefer.
 * [Shadow DOM](/shadow): to access shadow dom elements
 * [React](/react): to access React elements by component names and props
+* Playwright: to access locator supported by Playwright, namely [_react](https://playwright.dev/docs/other-locators#react-locator), [_vue](https://playwright.dev/docs/other-locators#vue-locator), [data-testid](https://playwright.dev/docs/locators#locate-by-test-id)
 
 Most methods in CodeceptJS use locators which can be either a string or an object.
 
-If the locator is an object, it should have a single element, with the key signifying the locator type (`id`, `name`, `css`, `xpath`, `link`, `react`, `class` or `shadow`) and the value being the locator itself. This is called a "strict" locator.

 Writing good locators can be tricky.
 The Mozilla team has written an excellent guide titled [Writing reliable locators for Selenium and WebDriver tests](https://blog.mozilla.org/webqa/2013/09/26/writing-reliable-locators-for-selenium-and-webdriver-tests/).
