Markus Padourek - Benefits of using Convention over Configuration
Node/io.js and npm is now the most flourishing ecosystem with over 200 npm modules being published a day*. While this poses a lot of opportunities for us to work together and build better software, it also comes with problems we as developers have to face: Which package should I now choose? How do I use it in my app? What input does it expect? etc. Making a multitude of these simple decision drains a lot of our energy - more than you might even think initially. Imagine now npm install and you are ready to go. You installed your addon, you already know what to expect and it hooks itself up into your app.
This is the philosophy behind convention-over-configuration: having a standard we all work with to automate mundane decisions. So we can focus on making our software better.
