afterNextRender<\/code><\/a><\/h3>\n\n\n\n

A function that allows registering a callback to be invoked the next time the application finishes rendering. It is similar to the ngAfterViewInit<\/code> lifecycle method but for signal-based components.<\/p>\n\n\n\n

The main use-case for this new lifecycle is to initialize a third-party, non-Angular-friendly library to hook itself on the DOM after Angular generates it:<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

afterRender<\/a><\/h3>\n\n\n\n

A function very similar to the afterNextRender<\/code>, with the difference that instead of running the registered callback just once, it will run it after every single render, similar to ngAfterContentChecked<\/code>. This could be used to read something from the DOM when it changes, such as the height of an element:<\/p>\n\n\n
