Re: Hosting a Large Number of Node Apps on the IBM i

"Routing steps" is probably acceptable terminology, although I think they are referred to as just "routes". We have to careful not to confuse routes within an app with the higher level route to the app in the first place. The latter is the top level URL:port on which the app is listening and the former is the internal routing to controllers handling the Ui for the app. I am sure Kelly is talking about the top level routing to the app and how to handle that as opposed to the question of internal routing to "screens" within the app.

Henrik,

Maybe "routing steps" is not the right term.

All HTTP requests need to be routed to specific JavaScript functions in
Node.js.

The idea is to use URLs to "route" requests appropriately. Say a URL
pattern such as the following is used to route HTTP requests:

/major-system/module/application/requested-action

Even a moderately scope system could very well exceed 20,000 unique URLs
for more than 20,000 possible JavaScript functions (request handlers).

So maybe routing is handled with a a series of nested conditions:

When URL-major-system = "human_resources" ...
When URL-module = "payroll" ...
When URL-application = "maintain_employee_payroll_deductions" ...
When URL-requested-action = "list_employees" ...

Since you mentioned having a "stateless" environment, that raises the
likelihood of managing state for each user, and possibly for each
application identified in a URL. Wouldn't some part of the URL be used as a
key for saving and restoring user state?
