I share the impression. My initial reaction to the changes in the control flow syntax was rather reserved, but I understand the motivation and the Angular team has released 14 major versions from 2016 where the migration went smooth like silk (at least in my experience), so I’m hoping on the qualities of the CLI for this as well.

Microfrontends are a technical solution to an organizational problem, if you can get away with not doing them, you might do yourself, your coworkers and your company a big favor.

Having said that, do you deploy this app, that you want to split into microfrontends, as a SaaS or is it more enterprisy and installed on-prem and access mainly via Desktop? If the latter, the venerable iframe might be your friend.

Also, if you really cannot help it, you should consider building an abstraction where you consider iframes, web-components, or lazily-loaded scripts as an implementation detail.

Source: I’m maintaining something that you’d in microfrontend term would describe as an application shell in Angular 2 since 2017. It hosts > 1000 different screens provided by > 60 dev teams ( > 450 devs) into a single user facing view. And I justified at least one years’ salary by talking my boss in 2019 out of using the approach again on a second product line (where the scope was narrower).

Well, I haven’t really got around to use Mastodon so much, but I can recommend Manfred Steyer, who might be a well-known name from quite a few major Angular conferences, who is @ManfredSteyer@mastodon.social

PMs and UXers are the Tom Sayers of the software world, whitewashing aunt Polly’s fence and making the other kids do the work and pay for the privilege.

Others have already mentioned the official documentation, which is a solid starting point. If you are jumping into a existing project, chances are that the steepness of the initial learning curve will be determined more by the choice of libraries beyond core Angular.

You’ll certainly have to also get familiar with the API of some ready-made component library (Material and the likes), as well as probably some sort of state management (NgRx). The latter in my experience is what needs the most time.

My recommendation: invest dedicated time into learning RxJS, for it is deeply entrenched into core Angular, and it is the basis of all more sophisticated state management libs. Don’t get overwhelmed, because in practice it will boil down to 6-10 operators you’ll use a lot (map, tap, filter, mergeMap, debouce, distincUntilChanged, take, combineLatest from the top of my mind) and the tail end of little operators you’ll look up when needed. https://rxmarbles.com is good for visual learners.
