INSIGHT

Event Loop Explained

  • PHP applications are typically synchronous, executing code linearly.
  • Event loops enable asynchronous task orchestration, like Node.js, improving efficiency.
INSIGHT

Why Drupal Needs an Event Loop

  • Drupal needs an event loop to manage asynchronous tasks introduced by Fibers, like in BigPipe and the renderer.
  • This centralizes task orchestration, improving efficiency and reducing boilerplate code.
INSIGHT

Benefits of Event Loops

  • Fibers allows asynchronous operations while maintaining the appearance of synchronous code.
  • Event loops coordinate these asynchronous tasks for performance and developer experience.
