For DrupalCon in 2021, I presented on Migrating Into Layout Builder. For this presentation, I came up with this simple demo to illustrate the main concepts covered.
If you would like to run and poke around on this demo yourself, you can clone or download this repo, then:
- Run
composer installto get all the dependencies in vendor, etc. (NOTE: composer.lock assumes PHP 7.3;composer updatemay help if you are on a different version.) - Import the database. If using DDEV, you can restore the snapshot provided. Otherwise, you can use the
source_data/db.sql.gzfile.
You will have a single node created that is the home page, which is a basic page built using layout builder.
If you're NOT using the included DDEV configuration, you may need to change the paths in the migrations from /var/www/html to whatever makes sense in your environment.
The settings.ddev.php is set up for DDEV, but you can override any of it (especially $databases) with settings.local.php as you need to (you will need to create a settings.local.php).
Everything related to the presentation is in web/modules/custom/my_migrations.
There are some additional helpful modules I used while developing the demo, which you can see in web/modules/contrib.
