It is commonplace even now (as in you will have enough resources/jobs etc that you want, not that it will be the majority, or even any where close). But you really want to stick with a more mature ecosystem. The JS/Node ecosystem, and even the language is too much in flux. It's nightmare to keep up even for experience developer. You want something you can copy paste and know it won't throw back an error due to version upgrade.
Ruby on Rails, python + flask and even php would serve you better.
