Sure, here's the updated description with "I" instead of "We":
This pull request addresses the issue of prefetching resources for dynamic imports in Farm. The current implementation of prefetching in Farm only handles static resources, but dynamic imports require a more sophisticated approach to ensure that resources are prefetched at the correct time.
To solve this issue, I introduced a new
DynamicPrefetchResourcestruct that represents a resource that should be prefetched when its corresponding module is loaded. I also added a newdynamic_prefetchfield to theResourcesInjectorOptionsstruct that is a vector ofDynamicPrefetchResourceobjects.In the
ResourcesInjectorclass, I added a newinject_dynamic_prefetchmethod that injects a<link>element withrel="prefetch"for each dynamic prefetch resource. I also added anonloadevent listener to the<link>element that will prefetch the dynamic imports of the corresponding module when the<link>element has finished loading. Theonloadevent listener uses thegetDynamicModuleResourcesMapmethod from theFARM_MODULE_SYSTEMto get the dynamic imports of the corresponding module.Finally, I modified the
visit_mut_elementmethod to call theinject_dynamic_prefetchmethod in addition to theinject_preload_and_prefetchmethod when processing the<head>element.With these changes, Farm can now prefetch resources for dynamic imports at the correct time, improving the performance of applications that rely on dynamic imports.
