Support transitions between microfrontends

[joeldenning]

Not sure what the API or functionality will be for this yet. Some reading to help brainstorm - https://router.vuejs.org/guide/advanced/transitions.html

Some of the things that are critical for us is being able to use the same micro-app in different routes. We have a way of data transfer or message bus to pass information between the micro-apps to reset their states.
Right now, if there is an error the route transition doesn't happen smoothly. So, error handling should be part of this feature that happens when there is an error how to handle route transition.

Hi @helumalai, thanks for adding your perspective here.

Right now, if there is an error the route transition doesn't happen smoothly.

Could you help me understand what this means? What kind of error is happening, and how is the route transition not happening smoothly? Which framework are you using?

[helumalai]

@joeldenning sorry for the late response. We're using Nx workspace for our root application and the code is in the simplest form of Angular. Recently I figured that its to do the data resolution before the page is displayed because we build the Html page with apps lists dynamically pulled from the DB. So, was hoping there was an error handling of message display when an app is not being able to load correctly.

At some point, I'm hoping to share a GitHub sample project with Nx workspace, Angular root application, and single spa micro apps since there isn't much help out there if we choose a framework like Angular/React for the root application.

I see. Handling application errors is being tracked in #49. The issue here being discussed is showing a UI while successfully transitioning between routes.

@joeldenning Sorry for not continuing with this. Would you still like to follow up with this one?

[helumalai]

@joeldenning One of the behaviors that we noticed with the Angular root application is, if something goes wrong the microapps get loaded directly to the DOM instead of their respective positions in the HTML file.

I'm open to the feature, don't have plans to work on it in the near future
