Disabling Big Pipe on specific page?

Question

I have a specific page where I'd like to disable Big Pipe. The route of that page is entity.node.canonical, so I don't think doing an alterRoutes() is the correct approach. What other options do I have?

Answer 1

Add a specific route for the node and disable Big Pipe by adding the option _no_big_pipe:

mymodule.routing.yml

node.2:
  path: '/node/2'
  defaults:
    _title_callback: '\Drupal\node\Controller\NodeViewController::title'
    _controller: '\Drupal\node\Controller\NodeViewController::view'
    node: 2
  options:
    _no_big_pipe: TRUE
  requirements:
    node: '\d+'
    _entity_access: 'node.view'

Answer 2

I am currently using a different approach than below, based on Wim Leers' Big Pipe strategy demo.

In a nutshell, in the part where the code decides to ignore the Big Pipe placeholders, I perform my URL detection:

$current_uri = \Drupal::request()->getRequestUri();
if (str_starts_with($current_uri, '/path/to/page-to-ignore')) {
  return [];
}
