Node.js happy coding

I’ve been doing Node.js professionally for roughly 2 years. During that time, I’ve learnt a thing or two that keeps me away from troubles.

Use Promise instead of callback

ES6 gets native Promise already but if you prefer something more convenient that 3rd-party libraries offer, pick something like bluebird (it’s really really fast). Stay away from Q. I mean, just look at this .

Do not trust developer’s semver practice

use npm shrinkwrap instead

This command locks down the versions of a package's dependencies so that you can control exactly which versions of each dependency will be used when your package is installed.

Personally, i would prefer npm support something like --save-exact flag. That would be awesome.

Use linter

Respect the code convention. The ultimate goal is having code written by different developers, looks as if they were written by the same person.
