Progressive Web Apps with React

Screenshots

This is my favorite section of the Performance Tools, because it vividly illustrates how your application loads.

As we established earlier, users should see content within 1,000 ms of loading your application. Here, we can see that content first appears on our application at about 400 ms, so we’re looking good, but as our application grows (and our scripting burden increases) that may change, so now’s the time to optimize as much as possible.
