You need to use what is best for the job, there is a reason we have so many different programming languages.
Do some research (it does not look like the OP has done all that much) and pick what fits the situation and your company can support with knowledgable people.
You have to remember it is ECMAScript and has been around for about 15 years so it has had time to change and evolve.
There are large enterprises using nodeJS, like LinkedIn using it for the server interface for their mobile application.
When you talk of maintainability it is javascript, there are A LOT of people that know javascript, not to be confused with people that know jQuery but I wont go into that.
If you are looking for prebuilt things, look at npm it is a package manager for node so there are a lot of packages out there for things from i2c and bluetooth controllers to full web frameworks and test suites. They even have stuff for cli utilities.
