Are minification and concatenation of styles and scripts relevant in 2016?

Question

css

The essence of the question is in the title. And if there is not much difference with minification, it won’t get worse anyway, then with concatenation everything is not so simple. Does it make sense to do this in 2016, after all, HTTP \ 2 came out?

Answer 1

caniuse.com/#search=http2
Support is already good, but it's too early to stop concatenating files, I think. Moreover, it only works on https.
And minification will never be superfluous.

Answer 2

HTTP / 2 "left" on the server, but it has not yet reached the clients .
The simple answer is that if you don't have an ssl certificate, then http2 is still like walking to the moon. If there is a certificate, then you need to analyze user visits for the browsers used and then decide.
If you decide to jump, then yes, you can opt out of concatenation.

Answer 3

Why not? There are excellent automatic tools for this, so use them.

Answer 4

So far, the proportion of http2 browsers and http2 hosting is small, so you should not give up on optimization.
As an option - your own server that can http2 and check in the application / on the site whether the visitor's browser can use the new protocol: if it can, then disable optimization and return statics one by one.
Well, moderate minification without wrapping in eval will be useful in any case.
