Not the OP, but the plugins you want to look up are ALE and coc.

I've used ALE for a while and love it, but coc is the new kid on the block that often shows up in discussions of LSP.

ALE is very tunable, so it's good for us performance-nuts who don't want anything slowing down their editor without their permission.

coc takes a more batteries-included approach, and will allow you to hit the ground running / see the light sooner.
