This gives customers a number of advantages, together with the absence of content material flickering on a web page for finish customers, higher Net Core Vitals in sure situations, future-proof structure to permit for fine-grained code loading, the power to combine with present apps in a couple of strains of code, and the incremental adoption of hydration with the ngSkipHydration attribute in templates for parts performing guide DOM manipulation.
Angular 16 additionally gives migration schematics and a standalone migration information to assist builders as they transfer their apps to standalone APIs.
Builders can entry this by operating “ng generate @angular/core:standalaone” and the schematics will convert the code and take away additional NgModules lessons, altering the bootstrap of the venture to make the most of standalone APIs.
Customers additionally achieve entry to a number of new options with this launch, comparable to:
