typescript - Angular 2 - make imported modules accessible in child modules -

is possible make modules, imported in root module accessible in child modules?

for example, have root module imported formsmodule & reactiveformsmodule & custom routingmodule:

// ... @ngmodule({     // ...     imports: [         browsermodule,         formsmodule,         reactiveformsmodule,         routingmodule,     ],     // ... }) 

but problem in child routingmodule components reactiveformsmodule declarations not accessible, need import there (in routingmodule imports).

is way make imported modules accessible each other top bottom of import statement?

just imported export them module available child modules

exports: [         browsermodule,         formsmodule,         reactiveformsmodule,         routingmodule,     ],
