== Why is this an issue? Dependencies should be explicitly listed in the ``++package.json++`` file. Importing a module that is not declared as a dependency makes it an implicit one and is bound to create problems. For example, a code might depend on a module that is present in ``++node_modules++`` as a transitive dependency; this dependency could be updated or removed without you noticing that, which could make your code fail. ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) include::message.adoc[] include::parameters.adoc[] include::highlighting.adoc[] ''' == Comments And Links (visible only on this page) include::comments-and-links.adoc[] endif::env-github,rspecator-view[]
