Evolving Web: Contribute by Saying #DrupalThanks at DrupalCon Baltimore

wo, 2017/04/26 - 12:41pm

Drupal and the Drupal community are driven by volunteer contributions. There are many great ways to contribute that don't involve writing a single line of code. You could report a bug, edit a documentation page, test a new Drupal 8 feature, help a beginner on a forum, or help organize a meetup. Despite this, many Drupalers are shy about diving in.

After some reflection, the Evolving Web team realized that there's one way to contribute to the community that's really simple: thanking someone who has helped you. Someone who built a module you used, helped you in the issue queue, or has done a presentation you liked. It doesn't matter if you do it privately, publicly on Twitter, or whether you're Dries or a total beginner. 

As part of Evolving Web's "Drupal Love" sponsorship at DrupalCon Baltimore, we're hoping to encourage spontaneous expressions of gratitude by handing out 1,000 flowers, with a simple request: Give this flower to someone at DrupalCon Baltimore who helped you in some way. Spread #DrupalThanks.

It will make both you and them feel great, encourage contributions, prevent burnout, and maybe even start a virtuous cycle. Thanking somebody costs nothing, yet can mean so much.

Evolving Web will be handing out several prizes to both givers and receivers of public thanks, which include a day of free Drupal Training, a subsidized trip to attend DrupalCamp Montréal this June 15-18, and flower bouquets delivered to your home or office.

To participate, just thank someone publicly on Twitter, like this:

or like this:

or like this:

Or if you'd prefer to do it offline, come by our Evolving Web's booth and tell us who you are thanking.

Dropsolid: Drupal 8 migration strategies

wo, 2017/04/26 - 9:00am
26 Apr Drupal 8 migration strategies Kevin VB

Content is always one of the most important parts of a website. After all, the internet was designed for information sharing. As a result, upgrading to a new CMS implies the migration of content in some form or another. Taking this into account in the early stages is crucial when considering and preparing a CMS upgrade.
The Drupal community is very aware of content migration as a key success factor. Therefore, Drupal’s latest version (D8) has the
migrate module included in its core. This key functionality allows you to upgrade from an older Drupal version to Drupal 8, using a few simple configuration steps. Below, I will explain how this works and put forward a few alternatives for custom migrations.


Why should you migrate to Drupal 8?

Site speed is not only important for SEO; it also affects your visitors’ browsing time and exit rate. Drupal 8 comes with an improved caching system that makes Drupal fly - all while taking into account content modification. There are no more endless waits for caches to invalidate, thanks to the real-time cache invalidation using cache tags.
Another reason for migration is the Drupal community. Plenty of features are available to integrate in your own site for free, which in turn enables you to spend time and money on other things. The community also keeps an eye on continuous improvements to the existing code. Drupal 8 is a great example of this, with its foundations in the Symfony2 framework. Everything in D8 has been standardised in such a way that maintenance is a lot easier and time-effective.
Let there be no doubt that migrating to Drupal 8 is an excellent long-term move!


How exactly should I migrate to Drupal 8?

You can use the Drupal migrate module that is included in core to upgrade from an older Drupal version to Drupal 8. Make sure to install and enable required modules first.
An example: if your site uses special field types, those modules should also be installed in your new Drupal 8 website. When you’re done configuring your site, you just need to enable the following modules:

  • Migrate
  • Migrate Drupal
  • Migrate Drupal UI

This last module will direct you to a configuration page, where you can start the actual migration. Simply enter the database information from your existing Drupal site and let Drupal review the upgrade.

The review will give you a list of available upgrade paths, next to a list of modules that are currently missing. If you’re happy about the review, you can choose to start the upgrade. Drupal will start importing content, users and taxonomies into your Drupal 8 website. Be aware that a rollback mechanism through the UI of Drupal is not available at this time. Since the Drupal core migrate is built to support a certain number of cases, it is possible that your site is too complicated to import correctly with the Migrate Drupal module. Sometimes, writing a customised migration is a better approach.

How to write a customized migration?

In most cases, the Migrate Drupal module will result in a reinstall of your Drupal website because some parts have been imported in the wrong way. You can opt to play things safe and write the migration yourself.
Writing a migration in Drupal 8 is done with the Migrate Plus module. This module allows you to create a new Migration entity. Those entities are created in YAML.

# Migration configuration for News content. id: news_node label: News Content Type migration_group: demo_news source: plugin: news_node destination: plugin: entity:node process: type: plugin: default_value default_value: news langcode: plugin: default_value source: language_code default_value: nl title: post_title field_title: post_title path: path field_tags: plugin: migration migration: - news_terms source: tags_terms migration_dependencies: required: - news_terms

Example of a Migration entity: migrate_plus.migration.news_node.yml

Each migration entity can belong to a Migration Group entity and is defined in YAML with the key ‘migrate_group’. A whole group of migrations can be imported or rolled back at once with drush by installing the Migrate Tools module.

  • drush mi --group=”demo_news” Import all migration in group demo_news
  • drush mr --group=”demo_news” Rollback all migrations in group demo_news


The main key of a migration is a Drupal 8 plugin that tells the migration where the source information comes from. There are plenty of base source plugins available for Drupal 8.

  • SqlBase - in Drupal Core: lets you migrate from an SQL source.
  • URL - in Migrate Plus: lets you migrate from a URL which can return JSON, XML, SOAP.
  • CSV - in Migrate Source CSV: lets you migrate from a CSV source file.
  • Spreadsheet - in Migrate Spreadsheet: lets you migrate from a csv, xls or xlsx source file.

If this does not suffice, you can start from your own source that extends from the SourcePluginBase class.

We extended the SqlBase source for our news_node source plugin.

public function query() { $query = $this->select('post', 'p'); $query->fields('p', [ 'ID', 'post_title', 'post_name', 'post_date', ]); $query->condition('p.type', 'news'); return $query; }

Query function in news_node source.

The query function returns a Select object with the information needed during the migration. This object will be the source for our migration.
Next we need to tell the migration which fields we want to map to the migration. This is done with the fields method.

public function fields() { $fields = [ 'post_title' => $this->t('The Post Node title'), 'post_date' => $this->t('The Post creation time'), // ... ]; return $fields; }

In Drupal 7 we used prepareRow to provide field information that couldn’t be selected with a single query. In Drupal 8 this can be done with the prepareRow method. In our example we fetch a teaser image and then add the file ID and file alt to the migration source.

public function prepareRow(Row $row) { // Find related teaser attachment image. $file = $this->getTeaserImage($content_id); // Set a new property file_id. $row->setSourceProperty('file_id', $file['id']); $row->setSourceProperty('file_alt', $file['alt']); return parent::prepareRow($row); }

Add extra information to the migration in preparerow.

When we go back to the YAML confirmation of our migration entity, we see that there is also a destination key configured. In most cases this will be an entity:entity_type destination plugin. Migrate will then automatically create entities of the configured type. In our example, new nodes will be created. If needed, you can also simply create a new destination plugin, which performs extra actions during the import function.


The progress key in our configuration defines the field value mapping. It contains a mapping of keys and values where the key is the Drupal field name and the value is the source field name. In some cases, like ‘type’ or ‘language’, we use a default_value plugin which allows us to set the value of the field to a fixed value. In our example, we are creating new nodes of type news in Dutch.

In some cases, the source value comes from another migration. In our example the value of ‘field_tags’ comes from another migration, this is defined by using the ‘migration’ plugin and then specify the migration(s) in which the value is migrated. Whenever such migration dependent fields are presents an extra key ‘migration dependencies’ is necessary. This is an array of migrations which needs to run first.

I hope this post has helped you to provide some insight in migrating your website from D7 to D8! As always, you can reach out to me and the rest of the team via our website.


Jeff Geerling's Blog: Composer BoF at DrupalCon Baltimore

di, 2017/04/25 - 10:07pm

Tomorrow (Wednesday, April 25), I'm leading a Birds of a Feather (BoF) at DrupalCon Baltimore titled Managing Drupal sites with Composer (3:45 - 4:45 p.m. in room 305).

I've built four Drupal 8 websites now, and for each site, I have battle scars from working with Composer (read my Tips for Managing Drupal 8 projects with Composer). Even some of the tools that I use alongside composer—for project scaffolding, managing dependencies, patching things, etc.—have changed quite a bit over the past year.

As more and more Drupal developers adopt a Composer workflow for Drupal, we are solving some of the most painful problems.

For example:

Drupal 8 has a new upgrade model, and the promise is to make upgrades easy forever. The idea behind the upgrade model is great, and has already been proven in other projects like Symfony. However, there might still be some issues that need to be solved, as demonstrated by the recent 8.3 release and the security release that followed it.

Dries Buytaert: Drupal is API-first, not API-only

di, 2017/04/25 - 6:59pm

More and more developers are choosing content-as-a-service solutions known as headless CMSes — content repositories which offer no-frills editorial interfaces and expose content APIs for consumption by an expanding array of applications. Headless CMSes share a few common traits: they lack end-user front ends, provide few to no editorial tools for display and layout, and as such leave presentational concerns almost entirely up to the front-end developer. Headless CMSes have gained popularity because:

  • A desire to separate concerns of structure and presentation so that front-end teams and back-end teams can work independently from each other.
  • Editors and marketers are looking for solutions that can serve content to a growing list of channels, including websites, back-end systems, single-page applications, native applications, and even emerging devices such as wearables, conversational interfaces, and IoT devices.

Due to this trend among developers, many are rightfully asking whether headless CMSes are challenging the market for traditional CMSes. I'm not convinced that headless CMSes as they stand today are where the CMS world in general is headed. In fact, I believe a nuanced view is needed.

In this blog post, I'll explain why Drupal has one crucial advantage that propels it beyond the emerging headless competitors: it can be an exceptional CMS for editors who need control over the presentation of their content and a rich headless CMS for developers building out large content ecosystems in a single package.

As Drupal continues to power the websites that have long been its bread and butter, it is also used more and more to serve content to other back-end systems, single-page applications, native applications, and even conversational interfaces — all at the same time.

Headless CMSes are leaving editors behind This diagram illustrates the differences between a traditional Drupal website and a headless CMS with various front ends receiving content.

Some claim that headless CMSes will replace traditional CMSes like Drupal and WordPress when it comes to content editors and marketers. I'm not so sure.

Where headless CMSes fall flat is in the areas of in-context administration and in-place editing of content. Our outside-in efforts, in contrast, aim to allow an editor to administer content and page structure in an interface alongside a live preview rather than in an interface that is completely separate from the end user experience. Some examples of this paradigm include dragging blocks directly into regions or reordering menu items and then seeing both of these changes apply live.

By their nature, headless CMSes lack full-fledged editorial experience integrated into the front ends to which they serve content. Unless they expose a content editing interface tied to each front end, in-context administration and in-place editing are impossible. In other words, to provide an editorial experience on the front end, that front end must be aware of that content editing interface — hence the necessity of coupling.

Display and layout manipulation is another area that is key to making marketers successful. One of Drupal's key features is the ability to control where content appears in a layout structure. Headless CMSes are unopinionated about display and layout settings. But just like in-place editing and in-context administration, editorial tools that enable this need to be integrated into the front end that faces the end user in order to be useful.

In addition, editors and marketers are particularly concerned about how content will look once it's published. Access to an easy end-to-end preview system, especially for unpublished content, is essential to many editors' workflows. In the headless CMS paradigm, developers have to jump through fairly significant hoops to enable seamless preview, including setting up a new API endpoint or staging environment and deploying a separate version of their application that issues requests against new paths. As a result, I believe seamless preview — without having to tap on a developer's shoulder — is still necessary.

Features like in-place editing, in-context administration, layout manipulation, and seamless but faithful preview are essential building blocks for an optimal editorial experience for content creators and marketers. For some use cases, these drawbacks are totally manageable, especially where an application needs little editorial interaction and is more developer-focused. But for content editors, headless CMSes simply don't offer the toolkits they have come to expect; they fall short where Drupal shines.

Drupal empowers both editors and application developers This diagram illustrates the differences between a coupled — but headless-enabled — Drupal website and a headless CMS with various front ends receiving content.

All of this isn't to say that headless isn't important. Headless is important, but supporting both headless and traditional approaches is one of the biggest advantages of Drupal. After all, content management systems need to serve content beyond editor-focused websites to single-page applications, native applications, and even emerging devices such as wearables, conversational interfaces, and IoT devices.

Fortunately, the ongoing API-first initiative is actively working to advance existing and new web services efforts that make using Drupal as a content service much easier and more optimal for developers. We're working on making developers of these applications more productive, whether through web services that provide a great developer experience like JSON API and GraphQL or through tooling that accelerates headless application development like the Waterwheel ecosystem.

For me, the key takeaway of this discussion is: Drupal is great for both editors and developers. But there are some caveats. For web experiences that need significant focus on the editor or assembler experience, you should use a coupled Drupal front end which gives you the ability to edit and manipulate the front end without involving a developer. For web experiences where you don't need editors to be involved, Drupal is still ideal. In an API-first approach, Drupal provides for other digital experiences that it can't explicitly support (those that aren't web-based). This keeps both options open to you.

Drupal for your site, headless Drupal for your apps This diagram illustrates the ideal architecture for Drupal, which should be leveraged as both a front end in and of itself as well as a content service for other front ends.

In this day and age, having all channels served by a single source of truth for content is important. But what architecture is optimal for this approach? While reading this you might have also experienced some déjà-vu from a blog post I wrote last year about how you should decouple Drupal, which is still solid advice nearly a year after I first posted it.

Ultimately, I recommend an architecture where Drupal is simultaneously coupled and decoupled; in short, Drupal shines when it's positioned both for editors and for application developers, because Drupal is great at both roles. In other words, your content repository should also be your public-facing website — a contiguous site with full editorial capabilities. At the same time, it should be the centerpiece for your collection of applications, which don't necessitate editorial tools but do offer your developers the experience they want. Keeping Drupal as a coupled website, while concurrently adding decoupled applications, isn't a limitation; it's an enhancement.


Today's goal isn't to make Drupal API-only, but rather API-first. It doesn't limit you to a coupled approach like CMSes without APIs, and it doesn't limit you to an API-only approach like Contentful and other headless CMSes. To me, that is the most important conclusion to draw from this: Drupal supports an entire spectrum of possibilities. This allows you to make the proper trade-off between optimizing for your editors and marketers, or for your developers, and to shift elsewhere on that spectrum as your needs change.

It's a spectrum that encompasses both extremes of the scenarios that a coupled approach and headless approach represent. You can use Drupal to power a single website as we have for many years. At the same time, you can use Drupal to power a long list of applications beyond a traditional website. In doing so, Drupal can be adjusted up and down along this spectrum according to the requirements of your developers and editors.

In other words, Drupal is API-first, not API-only, and rather than leave editors and marketers behind in favor of developers, it gives everyone what they need in one single package.

Aten Design Group: Using BrowserSync with Drupal 8

di, 2017/04/25 - 5:15pm

TLDR: Just here for Browsersync setup? Skip to the steps.

I’m always looking for ways to reduce the time between saving a file and seeing changes on the screen.

When I first started working with Drupal, back in the day, I would ftp changes to a server and refresh the page. Once I found Transmit, I could mount a remote directory locally and automatically save files to the server. At the time, my mind was blown by the efficiency of it. In hindsight, it seems so archaic.

Then I started working with development teams. Servers were typically managed with version control. If I wanted to make changes to the server, I had to commit code and push it up. It was time to act like a grown up and develop with a local server.

The benefits of developing locally are too numerous to list here, but the most obvious is not having to push changes to a remote server to see the effects. I could just save a file, switch to the browser and refresh! What was taking minutes was reduced to seconds.

My progression of development practices went something like this.

“Oy, hitting cmd+r is so tedious. What’s this? LiveReload? OH MY GOD! It refreshes the page immediately upon saving! It even injects my CSS without refreshing the page! I’m so super fast right now! Whoa! Less! I can nest all my CSS so it matches the DOM exactly! Well that was a terrible idea. Not Less’s fault but ‘Hello Sass!’. Because Compass! And Vertical Rhythm! And Breakpoint! And Susy! Holy crap, it’s taking 8-12 seconds to compile CSS? Node sass you say?. That’s so much faster! Back down to 3 seconds. Wait a minute, everything I’m using Compass for, PostCSS handles. BOOM! Milliseconds!”

This boom and bust cycle of response times of mine has been going on for years and will continue indefinitely. Being able to promptly see the effects of your changes is incredibly important.

In 1968, Robert Miller published a paper in which he defined 3 thresholds of human-computer response times.

  • .1 sec. To feel like you are directly manipulating the machine
  • .1 - 1 sec. To feel like you are uninhibited by the machine, but long enough to notice a delay
  • > 10 sec. At this point, the user has lost focus and is likely to move onto another task while waiting for the computer.

In short, less than a second between making a file change and seeing the result is ideal. More than that and you’re likely to lose focus and check your email, Slack or Twitter. If it takes longer than 10 sec. to compile your code and refresh your browser, your productivity is screwed.

One of my favorite tools for getting super fast response times is Browsersync. Browsersync is a Node.js application that watches your files for changes then refreshes your browser window or injects new CSS into the page. It’s similar to LiveReload but much more powerful. The big difference is that Browsersync can be run in multiple browsers and on multiple devices on the same LAN at the same time. Each connected browser will automatically refresh when code changes. It also syncs events across browsers. So if you scroll the page in one browser, all your connected browsers scroll. If you click in one browser, all browsers will load the new page. It’s incredibly useful when testing sites across devices.

For simple sites, Browsersync will boot up its own local http server. For more complex applications requiring their own servers, such as Drupal, Browsersync will work as a proxy server. Setup is pretty simple but I’ve run into a few gotchas when using Browsersync with Drupal.

Setting up Browsersync Local dev environment

First things first, you’ll need a local dev environment. That’s beyond the scope of this post. There are a few great options out there including DrupalVM, Kalabox and Acquia Dev Desktop.

For this tutorial, we’ll assume your local site is being served at

Install Node

Again, out of scope. If you don’t already have node installed, download it and follow the instructions.

Install Browsersync

Browsersync needs to be installed globally.

npm install browser-sync -g

Change directories to your local site files.

cd wherever/you/keep/your/drupal/docroot

Now you can start Browsersync like so:

browser-sync start --proxy "" --files "**/*.twig, **/*.css, **/*.js”

The above will start a browsersync server available at the default http://localhost:7000. It will watch for changes to any Twig templates, CSS or JS files. When a change is encountered, it will refresh any browsers with localhost:7000 open. In the case of CSS, it will inject just the changed CSS file into the page and rerender the page rather than reloading it.

Making Drupal and Browsersync play nicely together

There’s a few tweaks we’ll need to do to our Drupal site to take full advantage of our Browsersync setup.

Disable Caching

First we want to make sure page caching is disabled so when we refresh the page, it’s not serving the old cached version.

Follow the steps outlined under “Enable local development settings” in the Disable Drupal 8 caching documentation.

Now when you change a Twig template file, the changes will be reflected on the page without having to rebuild the cache. Keep in mind, if you add a new file, you’ll still need to rebuild the cache.

Avoid loading CSS with @import statements

This gotcha was much less obvious to me. Browsersync will only recognize and refresh CSS files that are loaded with a link tag like so:

<link rel="stylesheet" href="/sites/.../style.css" media="all">

It does not know what to do with files loaded via @import tags like this:

<style> @import url('/sites/.../style.css'); </style>

This is all well and good as Drupal uses link tags to import stylesheets unless you have a whole lot of stylesheets, more than 31 to be exact. You see, IE 6 & 7 had a hard limit of 31 individual stylesheets. It would ignore any CSS files beyond that. It’s fairly easy to exceed that maximum when CSS aggregation is turned off as any module or base theme installed on your site can potentially add stylesheets. Drupal has a nice workaround for this by switching to the aforementioned @import statements if it detects more than 31 stylesheets.

We have two ways around this.

1. Turn preprocessing off on specific files

The first involves turning CSS aggregation (a.k.a. CSS preprocessing) on for your local site and manually disabling it for the files you are actually working with.

In settings.local.php, set the following to TRUE:

$config['system.performance']['css']['preprocess'] = TRUE;

Then in your [theme_name].libraries.yml file, turn preprocessing off for any files you are currently working on, like in the following example.

global: version: 1.0.x css: theme: build/libraries/global/global.css: { preprocess: false }

This will exclude this file from the aggregated CSS files. This approach ultimately leads to a faster site as your browser loads considerably fewer CSS files. However, it does require more diligence on your part to manage which files are preprocessed. Keep in mind, if you commit the above libraries.yml file as is, the global.css file will not be aggregated on your production environment as well.

2. Use the Link CSS module

The easier alternative is to use the Link CSS module. When enabled, this module will override Drupal’s @import workaround and load all files via the link tag regardless of how many. The only downside to this approach is the potential performance hit of still loading all the unaggregated CSS files which may not be a big deal for your environment.

Add a reload delay if needed

In some cases, you may want to add a delay between when Browsersync detects a change and when it attempts to reload the page. This is as simple as passing a flag to your browsersync command like so.

browser-sync start --proxy "" --files "**/*.twig, **/*.css, **/*.js" --reload-delay 1000

The above will wait 1 second after it detects a file change before reloading the page. The only time I’ve ever needed this is when using Kalabox as a local development environment. Your mileage may vary.

In addition to the reload delay flag, Browsersync has a number of other command line options you may find useful. It’s also worth noting that, if the command line approach doesn’t suit you, Browsersync has an api that you can tie into your Gulp or Grunt tasks. Here at Aten we use Browsersync tied into gulp tasks so a server can be started up by passing a serve flag to our build task. Similar to the following gulp compile --watch --serve

Nuvole: Configuration Management dimensions

di, 2017/04/25 - 2:07pm
Key points from our configuration management sessions.

Unfortunately none of us from Nuvole are attending DrupalCon Baltimore and can’t, therefore, attend the “hallway track” and join discussions in person. We have held presentations about advanced configuration management in Drupal 8 at all Drupal events we attended in the last year including the last DrupalCon in Dublin. So I’ll try to cover some concepts here that could help the discussion about how the configuration management can be improved.

To me there are at least two important dimensions to configuration management in Drupal 8 and different contrib project have sprouted to address:

Vertical: transfer configuration between different environments of the same site.
Horizontal: transfer configuration between different sites.

Following are a few contrib solutions and core issues that address the different itches. This is not meant to be an exhaustive or definitive list but highlight the different problem spaces. Many more contrib solutions address some issues in this space to accommodate various different workflows.


Drupal 8 core only addresses this use case, however, there are some important cases not covered (yet). The management of configuration between the different environments is best taken care of by importing and exporting the whole sites configuration together.

Installing from existing configuration:

Contrib solution: Config installer
Core issues: Allow a site to be installed from existing configuration, Allow a profile to be installed from existing config

Environment specific configuration (ie devel only on develop)

Contrib solution: Config Split
Core issues: Allow exported configuration to be environment-specific, Allow development modules to opt out of config-export

Configuration with Content

Contrib solution: Default Content, Deploy


Due to the fact that the same tools can be used for both dimensions and the fact that in Drupal 7 features was abused for doing the vertical configuration management as well this concept may not be so clear. Ideally configuration between sites is shared from the development environment of one site to the development environment of another, and the vertical tools with drupal core are used for deployment. Moving configuration between different sites is done by moving a subset of configuration between environments.

Re-using a set of configuration in another site

Contrib Solution: Features
There are many more modules designed to deal with distributions and dealing with the paradigm that sites now own the configuration.

Inheriting installation profiles

Core issue: Allow profiles to provide a base/parent profile

Multisite with large portion of shared configuration

Contrib Solution: Config Split
While this is not the original problem it tries to solve, it is reported to be used for it..


I may have an obvious bias towards config split since we maintain that module but it is just one of many config related modules. I hope there is a fruitful discussion in Baltimore about configuration management in Drupal 8. BoF
