 You’ve built your application, and now you just need to deploy it. There are various ways that this could be done – from (S)FTP, to SCP and rsync, to running commands like “git pull” and “composer install” directly on the server (not recommended).

 A demo of some of the open source projects that I’ve been working on lately that are based on information from the Drupal.org API, including a PHP library for the API itself as well as some Drupal 8 modules that use it.

 [Drupal 8][0] was (finally) released on November 19th 2015, after almost 4 years of work and code commits by over 3,200 different contributors. Whilst it’s pretty much the same as the Drupal that we know and, hopefully, love, a lot has changed behind the scenes and under the hood!
