#Views Handlers - A Shakedown

This is a cheat sheet for information about extending the capabilities of Views by extending and building your own handlers. It will cover the basic handlers and attempt to cover some of the hooks that you might use when doing so. Including examples, basic documentation and some caveats where necessary. THIS IS NOT A COMPLETE LIST!! Consider the code of the handler your looking to extend to be the ultimate source of documentation. This is merely a convenience and a starting point.

_Ignore the tags in the included snippets, they are a convenience for formatting.

Extending / Including Your Handler

Determine which handler you're going to extend. (eg views_handler_field_numeric).
Create a PHP .inc file using the class name of your handler: views_handler_field_my_numeric_field.inc.

Summary Evaluation of Velocity 2014:

The mobile share of internet traffic is on pace to eclipse desktop traffic within 2014. As a whole, developers are doing a poor job of optimizing for mobile and users are frustrated. Mobile sites are actually trending slower year over year, even with faster devices accounted for.
Even desktop performance affects business metrics (like conversion rate, bounce rate, page views, etc..). This can usually be measured without taking the time to optimize performance; most sites are serving a mixture of fast and slow experiences to users. Just correlate the metric vs performance while controlling for some variables (like location).
From Puppet's State of DevOps Report in 2014 - IT performance was qualified in a statistically valid way and highly correlated with these three independent metrics: MTTR (mean time to recover), lead time for chang
