For the past couple of months we partnered with the&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/web.dev\/aurora\" target=\"_blank\">Chrome Aurora team<\/a>&nbsp;on improving the performance and DX of the hydration and server-side rendering. Today we are happy to share the developer preview of full app non-destructive hydration!<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"320\" src=\"https:\/\/tutorialbydevelopers.com\/wp-content\/uploads\/2023\/06\/hydration-1024x320.webp\" alt=\"\" class=\"wp-image-46\" srcset=\"https:\/\/tutorialbydevelopers.com\/wp-content\/uploads\/2023\/06\/hydration-1024x320.webp 1024w, https:\/\/tutorialbydevelopers.com\/wp-content\/uploads\/2023\/06\/hydration-300x94.webp 300w, https:\/\/tutorialbydevelopers.com\/wp-content\/uploads\/2023\/06\/hydration-768x240.webp 768w, https:\/\/tutorialbydevelopers.com\/wp-content\/uploads\/2023\/06\/hydration.webp 1400w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p id=\"7b44\">In the new full app non-destructive hydration, Angular no longer re-renders the application from scratch. Instead, the framework looks up existing DOM nodes while building internal data structures and attaches event listeners to those nodes.<\/p>\n\n\n\n<p id=\"9b3f\">The benefits are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>No content flickering on a page for end users<\/li>\n\n\n\n<li>Better&nbsp;<a href=\"http:\/\/web.dev\/vitals\" rel=\"noreferrer noopener\" target=\"_blank\">Web Core Vitals<\/a>&nbsp;in certain scenarios<\/li>\n\n\n\n<li>Future-proof architecture that enables fine-grained code loading with primitives we\u2019ll ship later this year.
