This package allows the creation of express application modules which define views, static content, and routes. By implementing optional hook functions in the module, an express application can invoke the defined functions across all modules at key points in the initialization. In this way, the often crowded app.js initialization for an express application need only worry about the sequencing of the module hook invocations. Dependencies on other node packages can be maintained together with the code that use them in the module, not as a direct dependency of the main application.
