Speed up the application in the mind — let everyone think that everything loads quickly

You made a good, beautiful, complex application. But there was a problem: APIs didn't manage to be made fast and the application loads slowly. The solution was chosen simple — overlay with ajax-loader until everything loads. Can this solution be improved? Is it possible to make your application accessible even before data has come from the server and there would seem to be nothing to show?

In the talk, Viktor will tell about such "deceitful accelerations" and simple techniques that can make content available earlier. At the same time, we'll agree that we won't touch API with its speed, the frontend developer can do everything! Speaker will tell how the team used all these tricks and real solutions in working on a project of 5 years length. And how we measured and confirmed all this.
