img persistence is only for local instances of app, check out saveImagesLocally branch
The app uses dependency injection in numberous locations. A ‘handle’ object is creataed where desired pathnames are co-joined with requestHandlers - functions that will be invoked.
This ‘handle’ key:value object is injected top-level into the main ‘start’ method, which is used to spin up the server.
By injecting it within this level, we are able to access it in different locations in subsequent use.
In a similar way, both the ‘route’ module, the mongoDB db connection, are injected , which then provides the machinery to use the handle object and connection using the pathname obtained from the url.
Yes, express would sure be a lot easier but learned a lot this way :)
