These days, Node.js as main back-end technology has already gained enormous following, with world's top companies using Node.js it as key part of their technology stack. We, too, recently included it in our offering - with in-house initiatives like our starter app already proving themselves in real-world projects.
Node.js, with its minimalism, universality, speed and - last but not least - common language being used is the perfect tool to develop and run all these tools.
Front-end application written with React, and built using Webpack? Or maybe Ember.js is more up your alley, with ember-cli handling all tooling around the project? Perhaps we’re talking about Gulp tasks, if not some less-popular solutions, like Grunt, Brunch or several others?
The aforementioned tools are just some of the most striking examples of how Node.js is already a commonplace even in front-end development - there are many more positions that could be easily found and mentioned.
