Test and track app advanced metrics during continuous integration

Which would be the best practice to test/track our React application at a higher level?

We use Jest which is great for unit testing but I want to see if my commits will actually make the code slower, the bundle size bigger, the first load time, etc.

I can do it by hand I guess, but I am wondering if there already are tools out there for this purpose?

Also how can I keep track of those metrics over time?

Edit= lighthouse ci seems to be a good candidate but would like to know the best practices (http://ift.tt/2p0Nul3)

Thanks
