Interactor VS Canvas LMS

While there are other libraries out there like Dry-Transaction and Interactor, StepSequencer stands out in its simplicity and flexibility. Here's why:

At my current job we use `interactor` which is similar, but simpler, and the precursor to light-service: https://github.com/collectiveidea/interactor

Thanks for the info. I like the sounds of that article. I think I was sort of thinking along those lines myself but didn't know what to refer to it as. I stumbled on to this as well after reading the article: https://github.com/collectiveidea/interactor.

Interactor

You might be looking for an interactor pattern for these services. I've used this gem for similar things before and have had good experiences.

FWIW Interactor has only received bugfixes and a single enhancement over the last 4 years: https://github.com/collectiveidea/interactor/blob/master/CHANGELOG.md and before that, the last meaningful change was 8 years ago.

Looks a lot like the Interactor pattern: https://github.com/collectiveidea/interactor

I see many senior Ruby developers around me going away from that magicness (like all the validations and callbacks) to move away from fat models, using libs like https://github.com/collectiveidea/interactor and have their own control.

The Interactor and ActiveInteraction gems are both great libraries for implementing this pattern.

I did not realize that Canvas is open source. That's an LMS most people like. You have hosting space and server-side savvy, you could set that up: https://github.com/instructure/canvas-lms

Canvas go brrrrrrrr

Also look at Canvas.

github.com/instructure/canvas-lms (745k lines): A popular LMS (learning management system).

No it's not. From a practical standpoint, I'm not even sure how that could work. You would have to require all browsers to be open source AGPL in order to load a web page served by it. By way of analogy it seems the equivalent of requiring the mouse and keyboard firmware to be licensed the same as the operating system.

A real life example is Instructure, which makes Canvas (which is agpl) but has other proprietary services that interact heavily with it. It's never been a problem

Look into Canvas LMS, I would recommend using 8GB RAM and at least 4 vCores. I have used it in the past (`2 years ago) and only had issues with cloning class/course templates.

If you're planning on doing this as business though, bear in mind this is a pretty crowded market. There's already at least one Rails-based LMSes out there (https://github.com/instructure/canvas-lms), and dozens in PHP-land.

There is also Canvas.
