Stanford Media

Version: 8.x

CircleCI

Maintainers: pookmish

Changelog: CHANGELOG.md

Description

The Stanford Media module is used to enhance the Drupal 8 core media management. The enhancements are listed below. This has been confirmed to work with ckeditor.

Field Formatters

In Drupal Core there is no way to select an image style on a media field. The provided field formatters pass in an image style or responsive image style into the display mode so that a desired image style is easier to display.

Embed Alter Plugins

When an media entity is being embedded into a wysiwyg, the core media implementation does not provide the user with certain customizations. The plugins (found in src/Plugin/MediaEmbedDialog) target specific media types and adds necessary customizations and pre-rendering in order to obtain the desired outcome.

Bulk Upload Page

This uses the above Dropzone Upload plugin. It allows a user to drag and drop as many allowed files as they would like. It will then provide a form for each item to allow the user to customize image alt texts, item titles, etc.

Media Duplicate Validation

To try to reduce the amount of duplicate images, the media duplicate validation will compare newly uploaded images and documents and compare them to existing items. If an item is similar enough, the user will be presented with the options to use an existing item, or continue to add the new item. Additional duplication plugins can be added when necessary.

Installation

Install this module like any other module. See Drupal Documentation If using this module on an existing site with media module previously enabled, it will over-ride existing media module configurations. Take extreme care if media entities already exist prior to this module.

When using composer to declare this as a dependency, custom modifications are needed for the dropzone library. Add or modify the root composer.json file. Below is a possible example of what to add for the dropzone library to be installed into the correct directory.

"extra": {
    "custom-installer": {
        "docroot/libraries/{$name}/": [
            "enyo/dropzone",
        ]
    }
}

When installing this module, it creates media entity types. One issue is when attempting to install the module on an install profile such as lightning or the standard install profiles. Each of these include media entity type configurations which conflict with the ones in this module. Extra steps are necessary if existing entity bundles already exist. One solution is to temporarily move all the config files in this module into the config/optional directory and then proceed with installation. This should create any missing media bundles and create the entity browsers that are included with this module. The reason for the conflicts is due to dependencies of other modules. Other modules and other config files can declare dependency on the configurations of this module. If all configurations of this module were placed in the config/optional directory, it would cause dependency issues during module/profile installation.

Configuration

  1. Add the Media Library button to the WYSIWYG as needed and check the box "Embed media".
  2. If the WYSIWYG is configured to limit allowed HTML Tags, ensure the the below is added to the list of allowed tags: <drupal-media data-entity-type data-entity-uuid data-caption data-align data-* class>
    • Although data-* would allow all data attributes and you wouldn't need to add any others, the UI form validation will throw an error without the above attributes.
    • data-caption is only required if captions are allowed. This has to be added and data-* cant be relied on due to hard coded checking of the embed form.
    • data-align is only required if the media can be aligned. Similar issue as data-align above.

Troubleshooting

If you are experiencing issues with this module try reverting the configuration files. If you are still experiencing issues try posting an issue on the GitHub issues page.

Developer

Development tools: To build and compile the CSS, Javascript, and Image assets required to make this theme great, you will need to have npm and nvm installed. Navigate to the root of the theme then.

Run:

nvm use
npm install

This project uses webpack to assemble the assets for this theme. To compile sass, javascript and push all assets in to place:

Run:

npm run publish

This script will compile all assets from /src into /dist.

Check out package.json for additional npm scripts and functionality.

Contribution / Collaboration

You are welcome to contribute functionality, bug fixes, or documentation to this module. If you would like to suggest a fix or new functionality you may add a new issue to the GitHub issue queue or you may fork this repository and submit a pull request. For more help please see GitHub's article on fork, branch, and pull requests

Releases

Steps to build a new release:

  • Checkout the latest commit from the 8.x-2.x branch.
  • Create a new branch for the release.
  • Commit any necessary changes to the release branch.
  • Make a PR to merge your release branch into master
  • Give the PR a semver-compliant label, e.g., (patch, minor, major)
  • When the PR is merged to master, a new tag will be created automatically, bumping the version by the semver label.
  • The github action is built from: semver-release-action, and further documentation is available there.
