The full-page wpScriptModuleExport defined in interactivity-router should not be bundled in Wordpress core yet as it is experimental. There is no mechanism in wpScriptModuleExports right now that supports building a script module but not including it in core. Since this is likely to be a rare instance we have opted to hard-code an exclusion in core's build until this module is no longer experimental.

Confirmed that this one script module is excluded.

// Exclude the experimental './full-page' export from @wordpress/interactivity-router.
// This export is defined in Gutenberg's package.json but should not be bundled in Core
// as the feature is still experimental and not ready for inclusion.
if ( moduleName === 'interactivity-router' && exportName === './full-page' ) {

Newbe question, why is this module defined in "interactivity-router" and not its own package that I guess depends on @wordpress/interactivity-router

I'll cc @luisherranz and @DAreRodz on that question, because I don't have context for the decision.

I'll let @DAreRodz confirm it, but I think it's one of the cases that was considered and in principle it would be possible.

In any case, that wouldn't prevent us from the need to add a hardcoded exclusion in WordPress Core, would it?

Yeah, it should be possible. It's bundled as a separate module, and its only dependency is @wordpress/interactivity-router. I don't remember why we decided to keep both modules in the same package, to be honest. 😄

@youknowriad, just curious. Is it expected that Gutenberg packages only expose one module?

Well for a long time, the expectation was 1 package = 1 script, and then when we did modules, we went on a different direction (started on interactivity).

I don't mind much, but I think we need clarity:

  • Should we allow multiple "scripts" like we allow "scripts modules"
  • How do we decide if we should do a separate package or not?
