The best of Drupal, curated by Acquia
Lightning's mission is to enable developers to create great authoring experiences and empower editorial teams.
You'll notice that Lightning appears very sparse out of the box. This is by design. We want to empower editorial teams and enable developers to jump-start their site builds. That means that a developer should never have to undo something that Lightning has done. So we started with a blank slate and justified each addition from there.
The preferred way to install Lightning is using our Composer-based project template. It's easy!
$ composer self-update $ composer create-project acquia/lightning-project MY_PROJECT
If you don't want to use Composer, you can install Lightning the traditional way by downloading a tarball from Lightning's GitHub releases page. (Please note that the tarball generated by Drupal.Org's packager does not include required Composer dependencies and should not be used without following the special instructions found there.)
You can customize your installation by creating a sub-profile which uses
Lightning as its base profile. Lightning includes a
Drupal Console command (
lightning:subprofile) which will generate a
sub-profile for you.
Through custom, contrib, and core modules plus configuration, Lightning aims to target four functional areas:
The current version of media includes the following functionality:
- A preconfigured Text Format (Rich Text) with CKEditor WYSIWYG.
- A media button (indicated by a star -- for now) within the WYSIWYG that launches a custom media widget.
- The ability to place media into the text area and have it fully embedded as it
will appear in the live entity. The following media types are currently
- Instagram posts
- Videos (YouTube and Vimeo supported out of the box)
- Drag-and-drop bulk image uploads.
- Image cropping.
- Ability to create new media through the media library (/media/add)
- Ability to embed tweets, Instagrams, and YouTube/Vimeo videos directly into CKEditor by pasting the video URL
Drupal community members have contributed several modules which integrate Lightning Media with additional third-party media services. These modules are not packaged with Lightning or maintained by Acquia, but they are stable and you can use them in your Lightning site:
Lightning includes the Panelizer module, which allows you to configure the layout of any content type using a drag-and-drop interface (Panels IPE). Lightning also includes a Landing Page content type for you to create landing pages with their own one-off layouts and content.
Any content type that uses Panelizer will allow you to set up default layouts for each view mode of that content type, which you can choose from (or override on a one-off basis) for individual pieces of content.
Eight layouts are provided out of the box by Panels. You can create your own layouts (see the Layout Discovery module bundled with Core) or install a contributed library of layouts like Radix Layouts.
Lightning includes tools for building organization-specific content workflows. Out of the box, Lightning gives you the ability to manage content in one of four workflow states (draft, needs review, published, and archived). You can create as many additional states as you like and define transitions between them. It's also possible to schedule content to be transitioned between states at a specific future date and time.
Lightning ships with several modules which, together, quickly set up Drupal to deliver data to decoupled applications via a standardized API. By default, Lightning installs the OpenAPI and JSON API modules, plus the Simple OAuth module, as a toolkit for authentication, authorization, and delivery of data to API consumers. Currently, Lightning includes no default configuration for any of these modules, because it does not make any assumptions about how the API data will be consumed, but we might add support for standard use cases as they present themselves.
If you have PHP's OpenSSL extension enabled, Lightning can automatically create an asymmetric key pair for use with OAuth.
We publish sprint plans for each patch release. You can find a link to the current one in [this meta-issue][meta_releases] on Drupal.org.
Demonstration videos for each of our user stories can be found here.

- If you upload an image into an image field using the new image browser, you can set the image's alt text at upload time, but that text will not be replicated to the image field. This is due to a limitation of Entity Browser's API.
- Some of the Lightning contributed media module listed above might not yet be compatible with the Core Media entity.
- Using the bulk upload feature in environments with a load balancer might result in some images not being saved.
Drush is not aware of the concept of inherited profiles and as a result, you will be unable to uninstall dependencies of any parent profile using Drush. You can still uninstall these dependencies via the UI at "/admin/modules/uninstall". We have provided patches here for Drush which allow you to uninstall dependencies of parent profiles.
