Ask HN: What do you do to speed up/ease software development?

[peapod91]

Just wondering what tricks/tools the HN community uses to help reduce coding time/effort. For example, Jade as a CSS pre-processor, Stylus as a temple engine for node, twitter bootstrap, text-editor autocomplete config, custom scripts, keyboard shortcuts, other packages/libraries like jshint, debug tools, coding practices, aliases, etc.

My current stack involves node, angular, postgresql, express, bootstrap, and android, but please feel free to add any tip that you've noticed helped make development easier and/or faster!

Thanks!!
