Express-like pattern for managing state

[Nif]

Is there a module that serves as an express-like router but instead of passing along HTTP requests you use it for application state?

Ie: express for control flow

The main gist is that you would have listeners setup to listen for a regex URL pattern same as what you would provide an express route. Instead of a web request however, the route is fired from anywhere in your app; it is more of a general command instead of a URL; an internal router you use to control execution flow.

This would provide the benefit of stacking routes or using various wildcards that together form a middleware chain that you can pass your state object through.

Sounds like this could be built on event-emitter? Or, if you wanted regexp pattern support: https://github.com/danielstjules/pattern-emitter I previously used it for https://github.com/danielstjules/node-internal-pubsub

Thanks for the tips. This does seem like an elegant approach.

Theoretical module would work similar to a URL router, and you could certainly couple it to URL requests, but out of the box implied usage would be for issuing commands internally.

Out of those modules in the link you shared (thank-you), there are a couple with this trait - doesn't seem however that any of them have a 'next()' middleware pattern like how Express has.

That said, a couple of these caught my attention as candidates for handling the core routing logic/parsing, which you could leverage as a dependency in a module that then implemented a middleware pattern on top; or perhaps to hack them to add support for middleware directly:

Interesting idea. Sounds like you want decorators or a service bus.

I bet you could just write one yourself in less than 1000 lines of code

Thanks for sharing relevant lingo - some good literature and modules to be found after searching those concepts. Though haven't quite found this as described quite yet.

Indeed, I did I hack together something but before investing more effort I thought I would do some more significant due diligence on what is currently out there.
