27 Optimizing application delivery

 

This chapter covers

  • Reducing the size of the application using dynamically loaded modules
  • Using server-side rendering to create an HTML representation of the application
  • Using rehydration to transition from server-rendered HTML to browser-generated content
  • Prerendering the application to create a static HTML representation of the application

Complex Angular applications can require large JavaScript files, which can take a long time to download over a slow network connection. In this chapter, I describe the features Angular provides for optimizing application delivery to minimize the amount of time before the user can interact with the application.
