The one thing that golang really needs is a templating library that doesn't suck, Html bindings in this language feel more like an after thought and this is coming from a person that really likes this language.
This is a very simple and clean Go templating library.
There are plenty of valid criticisms of React/etc, but the one thing they got really really right was making "templates" be normal functions that return a data structure representing the HTML. Logic is way less awkward, no global variables spanning partials in different files and it's impossible to write incorrectly nested markup. I really wish backend-only frameworks would steal that idea.
