3.19 - Preconnect to external domains - Beacon insertion part

[piotrbak]

User Story
As a user, I’d like beacon to collect data when there’s no entry in the db

Acceptance Criteria

• When visiting the uncached page while no data in DB, the same beacon script is added to process preconnects to external domains (no regression for beacon script injection)

Most of the part that handles this have already been introduced in 3.16 . We can find that module here We just need to declare the factory to be loaded there.

Scope a solution ✅

• Create a Factory for PreconnectExternalDomains like the way we do here for ATF if not created
• Create the queries method (product) required for this task if not created and make sure it extends WP_Rocket\Engine\Common\PerformanceHints\Database\Queries\AbstractQueries and implements ``WP_Rocket\Engine\Common\PerformanceHints\Database\Queries\QueriesInterface
• Update service providers if not already having the factory

Estimate the effort ✅
