Tide + https://github.com/jscheid/prettier.el + projectile + helm work wonders. Been using this for +3 years now and its one of the bigger productivity improvements in my recent years of emacs and programming practice.

At work, I actually try to get ppl away from Jetbrains IDEs because they are slow and their typescript and prettier support seems pretty buggy to me.

Unfortunately, most developers I meet these times are not the kind of hacker types that want to understand and optimize their tools but rather just to get stuff done on the surface (which is totally fine). So emacs isn't just a good fit for them.

> prettier support

I use emacs/tide/prettier-js, but the prettier formatting only happens on save. Do you have settings that make emacs adhere to prettier formatting as it goes along?
