Drupal 8 production sites

Based on D8's core theme 'Stable', our new agency website http://www.internet.ltd.uk is designed to demonstrate presentation quality and speed/performance aspects of the new system. We achieved a Pagespeed result of 90 by careful optimisation and coding. We also used css flexbox to manage design elements.

The Debug tool helped greatly with the identification and customisation of twig templates.

You can surely make something big with Drupal 8, but why not do something small with D8 either :-)

Here's a small company profile site I recently made with D8, started shortly after release of 8.0.0:

http://www.gims.de.com

Used no contrib modules on this page just D8 core, Forty Two as Theme (https://www.drupal.org/project/fortytwo) and some Jquery/Javascript Plugins.

I was looking for D8 code to create Nodes from a cvs file. I understand that this would normally be the work of a feeds module. But as D8 is kind of new, and I have this requirement anyway, I wanted to create a module that will create a couple of custom node/content types.. then populate the nodes with about 30 records from a cvs file.
My use case is that this would be a way to create a site with just modules, including real data. Then feeds could take over afterwards.
I also want to create the Views for these content types.

Memorial Sloan Kettering Cancer Center was one of the first enterprise sites to launch built on Drupal 8 on 5/6/15

Recently, the website letemps.ch has been relaunched on Drupal 8 / NP8.

This is a major milestone for Drupal 8 readyness and Dries honored the project with his tweet "With 4.2 million page views per month, Le Temps is probably the largest website on Drupal 8"

A post about the relaunch can be found at the MD Systems blog:

We are excited about the successful relaunch and very happy to see so many people interested in the project.

gbyte.co has been ported to Drupal 8!

Upgrade path

Content types were created manually, after that most of the migration happened with custom scripts including all nodes, users and files.

The website was created between beta 13 and 15. Though beta-to-beta upgradability was first announced when beta 15 came out, in fact I had no serious issues upgrading core modules from beta 13 to 15. Upgrading contrib modules like colorbox, libraries, honeypot took code changes and patches.

Custom contributed module: Simple XML Sitemap

Within Drupal 8 we build an exiting new caching API (https://events.drupal.org/losangeles2015/sessions/making-drupal-fly-fast... + https://amsterdam2014.drupal.org/session/render-caching-drupal-7-and-8.html)

However that means that anyone building contrib or custom modules needs to declare their dependencies using cache tags and contexts.

That means, if you e.g. do:

then you need to add:

The inaugural Drupal North Regional Summit website was built by website sponsor Foster Interactive with Drupal 8. The website was produced on betas 6-10 with a multilingual component.

English: drupalnorth.org
French: drupalnorth.org/fr

The organizers wanted to make a bold statement about our region's talent and decided to launch the annual summit with a Drupal 8 theme and a multilingual Drupal 8 website.
