Chromatic: Atomic Drupal Development: Building Pieces Before Pages

Planet Drupal - 16 February 2015 - 9:12am

Many designers are praising the benefits of Atomic Design. Rather than designing pages, Atomic Design focuses on designing systems of individual, reusable components. Designers aren’t – or at least shouldn’t be – the only ones thinking this way. From content strategy to QA, the entire team must be on the same atomic page.

Development is one area of a project that stands to benefit the most from this change in thought. Organizing a codebase by individual components keeps developers out of each other’s hair, reducing the code and effort overlap that often occurs when building by page or section. It also makes the codebase much easier to understand and maintain. Developers will know where to find code and how to fix, alter, or extend it, regardless of the original author. After enforcing coding standards, only git’s history will know who wrote what. This all saves time and money.

Because there are many ways to do anything in Drupal, building every component with the same approach is crucial. In the Drupal world, this approach is known as “the Drupal way”.

Building a component the Drupal way

Individual blocks, panel panes, or other UI elements would be examples of a component in Drupal. They are placed into regions within layouts to build pages. Other pages may use the same component in the same or different regions. A given component may vary across pages, but the design and intended functionality are similar. A simple search form is a good example, but they can be much more complex.

Design deliverables often arrive as complete pages. If the designers haven’t already, identify the components that each page consists of. Break up the page’s layout into regions and those regions into components. Determine which components live on more than one page and if they vary between them. It also helps to identify different components that share design or functionality with others. It’s important to recognize early if they will be sharing code.

Before writing a line of code, determine where in the codebase the component will live. Organize custom modules by content types or sections and add relevant components to the same modules. A module exported with Features should be treated no differently than one created by hand; don’t be afraid to add custom code to them (please do). The end goal is to have all back-end and (most) front-end code for a given component living in the same module.

Warning: This article is about to move fast and cover more ground than it should. It will move from back-end to front-end. There are many wonderful resources about each topic covered below, so they will be linked to rather than recreated. This will instead provide a high level overview of how they fit together and will highlight the most important pieces.

Component containers and placement

The most common container for a custom component is a block, created with a series of hooks. Contributed modules like Context can help place them on the page. More complex projects may choose to build pages with the Panels module. For pages built with Panels, custom panel page plugins are a component’s container of choice.

The decision between blocks and Context, Panels, or another approach is important to make early in the project. It is also important to stick with the same approach for every component. This article will focus less on this decision and more on how to construct the markup within the container of choice.

View modes and entity_view()

If the component displays information from a node or another type of entity, render it with a view mode. View modes can render different information from the same entity in different ways. Among other benefits, this helps display content in similar ways among different components.

Create a view mode with hook_entity_info_alter() or with the Entity view modes contributed module. This module also provide template suggestions for each entity type in each view mode. Render an individual piece of information with a view mode inside of a component using entity_view() (you’ll need the Entity API module) or node_view(). Alter the entity’s information as needed using a preprocess function and adjust the markup in a template. Those pieces will be discussed later.

If a component lists more than one entity or node, build a view with the Views contributed module. It is best if the view renders content with view modes using the Format options. Create Views components with the Block (or Content pane for Panels) display(s). Views also provides template suggestions to further customize the markup of the component. The exported view should live in the same module as the code that customizes it. EntityFieldQuery might be worth considering as an alternative to using Views.

hook_theme() and render arrays

If the component does not display information from an entity, such as a UI element, build it with hook_theme(). Drupal core and contributed modules use hook_theme() to build elements like links and item lists. This allows other modules to override and alter the information used to render the element. Default theme functions and templates can also be overridden to alter their markup.

Choose a name for the element that will identify it throughout the codebase. Outline what information the element will need to build the desired output. Use these decisions to define it using hook_theme(). Again, keep this hook in the same custom module as the rest of the code for the component.

To render a hook_theme() implementation, construct a render array. This array should contain the name of the implementation to render and any data it needs as input. Build and return this array to render the element as markup. The theme() function is a common alternative to render arrays, but it has been deprecated in Drupal 8. There are advantages to using render arrays instead, as explained in Render Arrays in Drupal 7.

Custom templates

Drupal renders all markup through templates and theme functions. Use templates to construct markup instead of theme functions. Doing so makes it easier for front-end developers to build and alter the markup they need.

Templates place variables provided by entity_view(), render arrays, and preprocess functions into the markup. They should live in the “templates” directory of the same module as the rest of the component’s code. The name of a template will come from theme hook suggestions. Underscores get replaced with dashes. Tell hook_theme() about the template for each element it defines.

There should be no logic in the template and they should not have to dig deep into Drupal’s objects or arrays. They should only use an if statement to determine if a variable has a value before printing its markup and value. They can also use a foreach to loop through an array of data. Further manipulation or function calls should happen in a preprocess function.

Preprocess functions

Use preprocess functions to extract and manipulate data such as field values and prepare them for the template. They are the middleman between the input and the output.

Preprocess functions follow the naming convention of hook_theme() implementations. Common base themes often use Drupal core’s preprocess functions, such as hook_preprocess_node(), in their template.php file. Keeping all preprocess functions in one file will create a mess in no time. Instead, place preprocess functions in the modules that define the parts their working with. This might be the custom feature that contains the exported content type.

jQuery/JavaScript files

Create a separate JavaScript file for each component that needs custom JavaScript. Place it in a “js” directory within the module and name the file after the component. Be sure to use the Drupal behavior system and name the behavior after the module and component.

Add the JavaScript file to each page the component will appear on. If the component appears on most pages, it might be best to just add it to every page. This will cause less HTTP requests with JavaScript aggregation enabled. The best way to do so is with hook_page_build(). JavaScript files can also be attached to entities rendered through view modes within hook_entity_view(). The best way to add JavaScript to a hook_theme() implementation is by attaching it to the render array.

Sass components

When using a CSS preprocessor like Sass, there isn’t much of a penalty to dividing the CSS into many files. Create a new Sass partial for each component and give the file the same name as the component. Keep them in a “components” directory within the Sass folder structure. Unlike all other code mentioned in this article, it is often best to keep all CSS for these components within the theme. Only keep CSS that supports the core behavior of the component in the module. Consider what styles should persist if it were a contributed module used with other themes.

In the component’s template, base the class names off of the component’s name as well. This makes it easy to find the component’s Sass after inspecting the element in the source. Follow the popular BEM / SMACSS / OOCSS methodologies from there.

Coming up for air

As mentioned, there are often endless ways to complete the same task in Drupal. This makes learning best practices difficult and “the Drupal way” will vary in the minds of different experts. The best way to grasp what works best is to start building something with other people and learn from mistakes. The approach outlined in this article aligns with common practice, but mileage will vary per project.

Regardless of approach, focusing on components before pages will only become more important. Drupal content is already displayed on everything from watches to car dashboards. The web is not made of pages anymore. Designers have begun to embrace this and Drupal developers should too; everyone will benefit!

Makak Media: Taking BackDrop For A Test Drive

Planet Drupal - 16 February 2015 - 8:41am

So the first BackDrop release is out there in the wild ready for a quick test drive! We're excited to see where this fork of Drupal 7 leads as we believe it to be a good complementary system to Drupal with a long term future.

First off we checked under the hood to get things configured and found the settings.php file in the root folder, which makes for easier access. Also all those txt files have been removed including the CHANGELOG.txt file, which we remove by default, as it supplies useful info to any hacker out there!

Naturally the installation process is very similar to Drupal but with a few less settings giving it a simpler feel.

Upon installation you're presented with a responsive admin menu with a slightly different structure to the standard Drupal menu. Responsiveness out of the box is great and the new menu again has a simpler look.

Enlightening - The Dark Art of Solr Search with Drupal Why this blog post?

Often when I add a search function to a Drupal website using Apache Solr, I'm amazed at how complex some people think this is. Many developers/site builders are of the belief that this is some kind of very-hard-to-master black art. They could not be more wrong.

So what I want to contribute back to the Drupal community is an understanding of how Solr works, why/how it differs from Drupal Core Search module, and the benefits Solr has over core search.

Categories: Drupal The Drupal 8 plugin system - part 2

Planet Drupal - 16 February 2015 - 2:38am

We saw in part 1 how plugins help us in writing reusable functionality in Drupal 8. There are a lot of concepts which plugins share in common with services, like:

  1. limited scope. Do one thing and do it right.
  2. PHP classes which are swappable.

Which begs the question, how exactly are plugins different from services?
If your interface expects implementations to yield the same behaviour, then go for services. Otherwise, you should write it as a plugin. This needs some explaining.
For instance, if you are creating an interface to store data in a persistent system, like MySQL or MongoDB, then it would be implemented as a service. The save() function in your interface interface will be implemented differently for both the services, but the behaviour will be the same, i.e., it takes data as input parameters, stores them in the respective data store and returns a success message.

On the other hand, if you are creating an image effect, it needs to be a plugin. (It already is. Check image effects as plugins). The core concept of image plugins is to take in an image, apply an effect on it and return the modified image. Different image effects yield different behaviours. An image scaling effect might not produce the same behaviour as that of an image rotating effect. Hence, each of these effects need to be implemented as a plugin. If any module wants to create a new image effect, it needs to write a new plugin by extending the ImageEffectBase class.

Plugins used in core

Let's take a look at the major plugin types provided by Drupal 8 core. An example plugin of each plugin types will be the subjects of future blog posts.

  1. Blocks
    Drupal 8 finally got blocks right. Custom blocks can be created from the BlockBase class.

  2. Field Types, Field Widgets and Field Formatters
    Check part 1 for how this is done in Drupal 8.

  3. Actions
    Drupal 8 allows module developers to perform custom actions by implementing the ActionBase class. Blocking a user, unpublishing a comment, making a node sticky etc. are examples of actions.

  4. Image Effects
    Image effects are plugins which manipulate an image. You can create new image effects by extending ImageEffectBase. Examples of core image effects are CropImageEffect and ScaleImageEffect.

  5. Input filters
    User submitted input is passed through a series of filters before it is persisted in the database or output in HTML. These filters are implemented as plugins by implementing the FilterBase class.

  6. Entity Types
    In Drupal parlance, entities are objects that persist content or configuration in the database. Each entity is an instance of an entity type. New entity types can be defined using the annotation discovery mechanism.

  7. Views related plugins
    A large collection of different plugin types are employed by views during the querying, building and rendering stages.

Plugin Discovery

Plugin discovery is the process by which Drupal finds plugins written in your module. Drupal 8 has the following plugin discovery mechanisms:

  1. Annotation based. Plugin classes are annotated and have a directory structure which follows the PSR-4 notation.

  2. Hooks. Plugin modules need to implement a hook to tell the manager about their plugins.

  3. YAML files. Plugins are listed in YAML files. Drupal Core uses this method for discovering local tasks and local actions.

  4. Static. Plugin classes are registered within the plugin manager class itself. This is useful if other modules should not create new plugins of this type.

Annotation based discovery is the most popular plugin discovery method in use. We will briefly look at how we create a new plugin type using this method in the next part.

Drupalpress, Drupal in the Health Sciences Library at UVA: two new drupal distros – one for voting, one for 3d printing e-commerce

Planet Drupal - 15 February 2015 - 12:29pm

Two new drupal distributions available on github

** is the distribution behind - it’s an attempt to run a political campaign through a virtual proxy…

** – this is the code behind it’s an e-commerce solution for 3d printing… A lot of this is implemented in rules and other well-standardized code thanks to Joe Pontani - a talented developer here in Virginia.  Joe integrated several third party tools, and set up the UVa payment gateway through Nelnet.

Both sites are getting updates over the next few months – the Charlottesville Council website also has a drupalgap implementation on it – absolutely awesome toolset…

18F API compliance is another feature I’m pretty stoked about… I got most of that done with the oauth2 server, views datasource, services and a couple of great notification features done with rules + views  i’ll get that feature out asap = it’s really convenient – matching a profile2 taxonomy field onto content taxonomy fields for notifications with new content.

Required or not required? To validate or not to validate? That is the question. So you've setup (the site builder's way, no custom forms) your required fields and custom validations for Node types, just to get this feedback from the customer:

That field we defined as mm..... as required (something trivial and not really critical such as an image file) is actually not always required. Users X and Y should be able to bypass that restriction.

Angie Byron: Webchick's "plain Drupal English" Guide to the Remaining Drupal 8 Critical Issues: DrupalCon Bogotá Edition

Planet Drupal - 14 February 2015 - 1:09am

(Apologies for the atrocious state of the HTML that follows; this content is originally from this Google Doc.)

Webchick's "plain Drupal English" Guide to the Remaining Drupal 8 Critical Issues: DrupalCon Bogotá Edition

DrupalCon Bogotá just finished up, and critical issue-wise we've managed to stay in the 50s for a few days (down from a high of 150 last summer!), so now seems like as good a time as any to write down what's left to ship Drupal 8!

This post will attempt to document all of the remaining 55 criticals (as of this writing), and attempt to offer a somewhat "plain English" (or at least "Drupal English" ;)) description of each, loosely categorized into larger areas in which we could really use extra help. There are over 2,600 contributors to Drupal 8 at this time, please join us!

(Note: These descriptions might not be 100% accurate; this is my best approximation based on the issue summary and last few comments of each issue. If I got the description of your pet issue wrong, please update your issue summary. ;))

Thrilling conclusion! (also known as "TL;DR")

Quick vocabulary lesson

Within this list, there are numerous "markers" used to signify that some of the issues in this list are more important to fix ASAP. These are:

  • D8 upgrade path: An issue tagged D8 upgrade path (currently, 13) means it blocks a beta-to-beta upgrade path for Drupal 8, generally because they materially impact the data schema or they impact security. Once we resolve all of these blockers, early adopters will no longer need to reinstall Drupal between beta releases, but can just run the update.php script as normal. This is currently our biggest priority.
  • Blocker: An issue tagged blocker (currently, 5) means it blocks other issues from being worked on. This is currently our second-biggest priority (or 0th priority in the case an issue blocks a D8 upgrade path issue :D). I've noted these as "sub-bullets" of the issues that are blocking them.
  • Postponed: Issues that are marked postponed (currently, 9) are either currently blocked by one of the "Blocker" issues, or we've deliberately chosen to leave off until later.
  • >30 days: These patches have a patch more than 30 days old, and/or were last meaningfully commented on >30 days ago. If you're looking for a place to start, re-rolling these is always helpful!
  • No patch: This issue doesn't have a patch yet. Oh the humanity! Want to give it a shot?

Other weird core issue nomenclature:

  • "meta" means a discussion/planning issue, with the actual patch action happening in related/child issues.
  • "PP-3" means "this issue is postponed on 3 other issues" (PP-1 means 1 other issue; you get the drift).
Current state of critical issues

Sections roughly organized from "scariest" to "least scary" in terms of how likely they are to make Drupal 8 take a longer time to come out.


Because Drupal 8 hasn't shipped yet, it's not following Drupal's standard Security Advisory policy, so there are still outstanding, public security issues (13 as of this writing). We need to resolve most of these prior to providing a Drupal 8 beta-to-beta upgrade path, as this is the time when we signal to early adopters that it's an OK time to start cautiously building real sites on Drupal 8.

Skills needed: Various

Security Parity with Drupal 7

This class of security issue is to ensure that when Drupal 8 ships, it won't have any regressions security-wise relative to Drupal 7.

  • Port SA-CONTRIB-2013-096 to D8 (D8 upgrade path) Here's one such issue for Entity Reference module. SA-CONTRIB-2013-096 addressed a relatively esoteric remote access bypass bug, and the patch needs to be forward-ported to Drupal 8.
  • Port SA-CONTRIB-2015-039 to D8 (D8 upgrade path)  SA-CONTRIB-2015-039 addressed two issues in Views module, a redirect and default permissions for disabled views. The first was fixed in D8, but access checks are still missing from a few views for the second.

Session and User Authentication API

Because of various intricate dependencies, the authentication part of Drupal 8 isn't yet converted to object-oriented code, and prevents us from further optimizing bootstrap. This set of issues fixes various problems with this part of the code, and ensures these important security APIs are complete and ready to ship.

  • REST user updates bypass tightened user account change validation (D8 upgrade path) Since Drupal 7, when you edit your user account, you have to provide the existing password when you want to change the password or e-mail. This security feature is currently by-passed by REST user updates as you can change the password or e-mail without providing the password.
  • External caches mix up response formats on URLs where content negotiation is in use (>30 days) Drupal 8's request processing system is currently based on content negotiation (which allows you to serve multiple versions of a document at the same URI based on what headers are sent e.g. Accept: text/html or Accept: application/json). This is generally considered the "right way" to do REST. However, various external caches and CDNs have trouble with this mechanism, and can mix them up and can send random formats back. The issue proposes changing from content negotiation to separate, distinct paths such as /node/1.json.

New security improvements

These issues affect new security improvements we want to make over and above what Drupal 7 does.

  • [meta] Document or remove every SafeMarkup::set() call One of the big security improvements in Drupal 8 is the introduction of Twig's autoescape feature, which ensures that all output to the browser is escaped by default. However, this is quite a big change that requires all of the code that was previously escaping content to stop doing that, else it gets double-escaped (so you start seeing < and " and whatnot in the UI). We originally introduced the ability to manually mark markup safe with SafeMarkup::set(), but the recommended approach is actually to use Twig everywhere, so this issue is to ensure that all remaining instances of the manual way are fixed, or at least documented to explain why they're using the non-recommended method.
  • Passing in #markup to drupal_render is problematic (>30 days) Another issue in the Twig autoescape space, we need to ensure that markup set by the "#markup" in e.g. form definitions is properly escaped.
  • Limit PDO MySQL to executing single statements if PHP supports it Remember SA-CORE-2014-005? Yeah, so do we. ;) This issue is to make sure that if another SQL injection vulnerability is ever found again, the damage it can do is more limited by eliminating the ability for MySQL to execute multiple queries per PDO statement.


Tied with security, 13 of the remaining issues are tagged Performance. While it may seem odd/scary to have this be a big chunk of the work left, it's a common practice to avoid premature optimization, and instead focus on optimization once all of the foundations are in place.

Skills needed: Profiling, caching, optimization, render API


Here are a sub-set of issues where we need performance profiling to determine what gives us the biggest bang for our effort.

Fix regressions relative to Drupal 7
  • [meta] Resolve known performance regressions in Drupal 8 This is the main tracking issue in this space. During the 8.x cycle we've introduced several known performance regressions compared to Drupal 7 (sometimes to make progress on features/functionality, other times because we introduced changes that we hoped would buy us better scalability down the line), which we need to resolve before release so that Drupal 8 isn't slower than Drupal 7. The performance team meets weekly and tracks their progress in a detailed spreadsheet.
Entity Field API

Tracked under the Entity Field API tag (currently 6 issues).

Skills needed: Entity/Field API, Form API, Schema API

  • Schema for newly defined entity types is never created (D8 upgrade path) When you first install a module that defines an entity type (for example, Comment), its database tables are correctly generated. However, if an entity definition is later added by a developer to an already-installed module, the related database schema won't get created, nor will it be detected in update.php as an out-of-date update to run.
  • FileFormatterBase should extend EntityReferenceFormatterBase (D8 upgrade path) Entity Reference fields define a EntityReferenceFormatterBase class, which contains logic about which entities to display in the lookup, including non-existing entities and autocreated entities. File field's FileFormatterBase class currently duplicates that logic, except it misses some parts, including access checking, which makes this a security issue. The issue proposes to simply make File field's base class a sub-class of Entity Reference's, removing the need of "sort of but not quite the same" code around key infrastructure.
  • FieldTypePluginManager cannot instantiate FieldType plugins, good thing TypedDataManager can instantiate just about anything Currently, you get a fatal error if you attempt to use Drupal 8's Plugin API to create a new instance of a field type. The current code in core is avoiding this problem by going roundabout via the Typed Data API instead. This issue's critical because these are two of the most central APIs in Drupal 8, and they should work as expected.
  • [META] Untie content entity validation from form validation Despite all the work to modernize Drupal 8 into a first-class REST server, there still remain places where validation is within form validation functions, rather as part of the proper entity validation API, which means REST requests (or other types of workflows that bypass form submissions) are missing validation routines. This meta issue tracks progress of moving the logic to its proper place.
  • Entity forms skip validation of fields that are edited without widgets (>30 days) If a field can be edited with a form element that is not a Field API widget, we do not validate its value at the field-level (i.e., check it against the field's constraints). Fixing this issue requires ensuring that all entity forms only use widgets for editing field values.
  • Entity forms skip validation of fields that are not in the EntityFormDisplay (No patch, >30 days) Drupal 8 has a new feature called "form modes" (basically analogous to "view modes" in Drupal 7, except allowing you to set up multiple forms for a given entity instead). Currently, we're only validating fields that are displayed on a given form mode, even though those fields might have validation constraints on other fields that are not displayed. Critical because it could present a security issue.

Views issues are generally tracked with the VDC tag. There are currently 6 criticals at this point which touch on Views (some already covered in earlier sections).

Configuration system

The configuration system is remarkably close to being shippable! Only 4 critical issues left. We're now working on finalizing the niggly bits around edge cases that involve configuration that depends on other configuration.

Skills needed: Configuration system, Entity Field API, Views

"Fix it, or else"

This subset of issues are things that are part of core currently, and we would really like to keep, but are willing to make some hard choices in the event they are among the last remaining criticals blocking release. The "postponed" among this list means "postponed until we're down to only a handful of criticals left." If these issues end up remaining in the list, we will move their functionality to contrib, and hope to add it back to core in a later point release if it gets fixed up.

Skills required: Various, but mainly low-level infrastructure and non-MySQL database skills.

  • [meta] (websites/infra) blockers to a Drupal 8 release (Blocker) This issue contains a "grab bag" of blockers that prevent an optimal Drupal 8 release, including things like semantic versioning support, testing support for multiple PHP/database versions, and support for Composer-based installations. If this issue is one of the last remaining criticals, we might choose to ship Drupal 8 anyway, and jettison one or more features in the process, such as…
  • [Meta] Make Drupal 8 work with PostgreSQL The meta/planning issue for fixing PostgreSQL (both in terms of functionality and in terms of failing tests). bzrudi71 is predominantly leading the charge here and making steady progress, but more hands would be greatly appreciated.
  • [meta] Database tests fail on SQLite (>30 days) Same deal as PostgreSQL but for SQLite. Unlike PostgreSQL though, this one doesn't have anyone leading the charge at this time, and it's also a lot harder to punt this to contrib, since we use it for various things such as testbot. Help wanted!

General house-keeping

These are all basic things we need to keep on top of between now and release, to ensure that when we're down to only a handful of criticals, we're ready to ship a release candidate. The good news is, these are also all generally really easy patches to make, and often also to test.

Skills needed: Basic patch rolling / reviewing / testing skills. (good for newbies!)

  • [meta] Ship minified versions of external JavaScript libraries (Postponed) Basically, in the Gilded Mobile Age™ we want to ensure that we're sending as little over the wire as possible, so scrunching various JS libraries down to the smallest possible file size needs to be the default. Separate issue from above because it needs to happen for both updated and existing JS libraries. Postponed because there'll be less work to do once all of the out-of-date JS libraries are updated and minified at the same time.

I couldn't figure out a nice heading for these, so here's the rest.

  • Remove _system_path from $request->attributes Symfony provides a $request object, which has an "attributes" property for the purpose of storing various contextual bits. But the problem with $request->attributes->get('_MAGIC_KEY') is that the values are undocumented, there's no IDE autocompletion, and it's not clear which are internal vs. public properties, so we have an issue at [meta] Stop using $request->attributes->get(MAGIC_KEY) as a public API. to try and stop doing that.

    However, _system_path in particular is used a ton, since it's very common to want to know the path of the current request. The patch exposes a "CurrentPath" service instead, which eliminates all of those issues.
  • Potential data loss: concurrent node edits leak through preview Because the temp store that Drupal 8's new node preview system employs uses an entity's ID as the key, rather than something uniquely identifiable to a user, if two users are editing the same node and hit preview at the same time, one of them is going to lose data due to a race condition.
  • Ajax file uploads fail on IE 9 Pretty much exactly what it says on the tin. :P
Thrilling conclusion! (also known as "TL;DR")

Well, not so thrilling, but at least a conclusion. :)

  • Anywhere you see a blocker issue, attack it with fire. Those are holding other criticals up.
  • The biggest area of focus right now is D8 upgrade path blockers. Many of them are security issues.
  • Another big area is Performance, both fixing existing regressions, and profiling to determine where our biggest wins are.
  • Views and Entity Field API are tied in third place for number of remaining criticals. Let's have a race, shall we? ;)
  • The configuration system is looking pretty good, but still has a handful of sticky issues left.
  • There are a series of important features we'll lose if they're not fixed up in time.
  • If you're looking for something somewhat easy/mundane, help yourself to one of the general house-keeping issues.
  • Don't forget about the other miscellaneous issues I was too tired to categorize.

Sorry this post was so long (and probably has its share of inaccuracies) but I hope it will be helpful to some. It's basically what I needed to get back up to speed after taking a few months off of Drupal 8, so figured I'd document my way to understanding.

Now, let's get 'er done! :D
