Media breakpoint in JS: "Harvey" alternatives? in GSAP Posted April 10, 2019 3 minutes ago, ¯\_(ツ)_/¯ said: How far back do you need to provide support for browsers? Harvey was adopted from Paul’s matchMedia.js, while Harvey was updated 6 years ago, Pauls was updated 2 years ago … so can you just use Pauls? Certain things work regardless of needing updated solely based upon their intensions, is Harvey beginning to fail for you in some way? Here are some GSAP specific examples you may find interesting: See the Pen vExQEy by osublake (@osublake) on CodePen See the Pen jLLqbY by osublake (@osublake) on CodePen See the Pen RGmdVx by PointC (@PointC) on CodePen etc., (some of those examples may be in the links @PointC mentioned above) No, Harvey is not failing at all! It works perfectly fine and I really do like the api it provides! But unfortunately the developer and also the company he works/ed(?) for, do not respond. Honestly, I have no clue, what could be improved with Harvey, so an update might just simply not be necessary. On the other hand, there is so much going on in the JS universe, that I kind of got accustomed that libraries receive changes on a more or less regular basis... Anyway, I was just curious, which solutions other people use and therefore shouted out the question. Thanks a lot [no idea how to cite your name!] for the hint about Paul's update and for the examples!
