@rx-angular/template

A lib for handling data streams in templates for high performance and ergonomic Angular UI's in large scale applications

@rx-angular/template was specifically designed to help developers reduce the boilerplate in templates and have performant change detection rendering and provide a migration path to go full zone-less.

Sub Modules

• LetDirective (*rxLet)
• RxFor (*rxFor)
• RxIf (*rxIf)
• UnpatchDirective (unpatch)
• PushPipe (push)
• TemplateDirective (*rxTemplate)

Experimental features

• 🧪 Viewport Priority (viewport-prio)

All experimental features are very stable and already tested in production apps for multiple month. The reason to have them in experimental is so we can make small typing changes without breaking changes.

Concepts

• reactive context

• local templates

• local variables

• render strategies

• Coalescing

• Coercing

• Scheduling

• Rendering Issues in Angular
