Ask HN: Do you need more than front end and Firebase education to ship product?

Whilst my world is on hiatus for the foreseeable, I've decided to learn enough web development to ship a few product ideas I've had on the back burner, for a mix of fun, profit and self development. Plan A was to just learn front-end development (HTML, CSS, JS, framework, UI/UX) and use a baas like Firebase or AWS for the back-end. Now, I'm a little concerned that relying on front-end and baas will bottleneck me in some way that isn't obvious to me as a newbie. Given the above, how valuable would a back-end education be (node/express or ruby on rails), even if I end up going the baas route? Notes: My product ideas are run of the mill Reddit for dogs, news aggregator, to-do list app type stuff. I'll be following one of the Odin Project's curriculums. They offer both front-end and full stack learning tracks. -Front end https://www.theodinproject.com/tracks/3 -Full stack Javascript https://www.theodinproject.com/tr
