Thanks to generous contributions from Fuzion and Beat Schnyder from basx GmbH, I was able to put in a few days work over the last month into the Drupal 8 integration module, allowing Drupal 8 and CiviCRM to interoperate.
I had done a large chunk of work of the initial work for this during Google Summer of Code last year but as Drupal 8 has been under heavy development, so much had changed that the module needed to be carefully picked over to bring back into a working state. Over the several days of funding I had, I managed to get both the module and install working against the latest Drupal 8 beta (at the time, beta-9 but now 10 too) and Civicrm 4.6.3 in time for the Denver CiviCon sprint.
You can check out the current state of things (along with all the bugs and so on) here: http://civid8.fudev.co.nz/ (login: demo password: demo). If you would like to explore deeper, such as testing how it works with Views, and later on with other Drupal goodies that aren't yet available in D8, then just ask us for a user account with more permissions. Fuzion is asking for contributions to help support this work - they are encouraged but not compulsory. Funds will go towards Drupal 8 support.
Any bugs you come across, please feel welcome to open an issue on JIRA and assign to me (Torrance).
For the adventurous at heart, I’ve documented the installation procedure, so you can have a go at installing a local copy to play with (and I will update this if it's not clear enough or there are issues in the process).
There’s still plenty of work to do, but the more eyes looking, the shallower the bugs. :)
