At the moment I use PyCharm as my integrated development tool for both front end and back end. My main stack is JavaScript, CSS, ECMAScript 6, Vue, Python, Django, Mako, and Markdown. Front-end work has been growing steadily lately, and PyCharm seems to be struggling. Atom, Sublime Text, and Visual Studio Code became the candidates; Atom is maintained by GitHub, has better community support, and is more configurable and more fun to play with.
