Lifecycle Hooks – RenderedCallback

Nirav Asodariya 27/12/2025   LWC

The purpose of the renderedCallback() lifecycle hook is to run logic after a Lightning Web Component has been rendered in the DOM. It is mainly used for tasks that require access to rendered DOM elements, such as querying elements, applying dynamic styles, or integrating third-party libraries. Using renderedCallback() ensures that the UI is fully available before performing DOM-dependent operations.
