Drupal 8 Update URL Alias Programmatically

Did you know we can update URL aliases via custom code in Drupal 8?

URL aliases are human-readable and SEO-friendly paths. They map to specific Drupal content. Additionally, these aliases replace the default system paths. Furthermore, they can be managed manually through the admin interface or programmatically using code.

We can update URL aliases programmatically in Drupal 8 with these steps:

1. The Pathauto module allows us to automatically generate URL aliases based on patterns we define. Furthermore, this is an optional step.
2. Then, we have to decide which entity we want to update the URL alias for, and load that entity with Drupal’s Entity API.
3. Next, we can set or update the URL alias using the path field. The field’s value should be the desired URL alias for the entity. For nodes, this field is accessed as $node->path->alias.
4. Furthermore, after updating the URL alias field, we have to save the entity to persist the changes to the database using the save() method on the entity object.

   Here’s an example of how we can update the URL alias of a node programmatically:
