I use Chai because it is best BDD library i know

I use Browserify because it works well with gulp

I use Mocha because yet no one invented better test framework for javascript

I use ESLint because developer's life is impossible without it

I use Travis CI because it is integrated with github

I use Babel because developers life is impossible without it

I use axios because it is isomorphic (universal) and has convenient API

I use gulp because so far it is self-explanatory and easy to scale

I use nodemon because it is simple.

I use MongoDB because it has low entry level and the new developers have much less issues maintaining applications built with it
