Drupal 10: Creating A Notification System Using The Message And ECA Modules

Drupal is a great platform to create communities of users where you can allow users to create their own content and interact with each other. One way of keeping users engaged on the site is by letting them know when other users are interacting with content they have created. This is quite a common occurrence on sites like LinkedIn or Facebook, where you will receive a notification when a user comments or likes one of your posts. The same thing can be put together in Drupal with just a few modules (and a few lines of code).
