I have built mini widgets that consist of a model, a controller a couple of stylesheets and a couple of lines of javascript. Whenever it turns out that I need something like that in the next app I am building, i have to do some copypasta from the app where I had built them. Needless to say, that is not fun.
So I’ve heard about component frameworks like Cells, Apotomo and Parts, which promise to alleviate this chore, but I couldn’t find any discussion around them or any other significant community activity, usage stats, and so on, to indicate their adoption. Except for a few blogposts, the community is oddly silent about component frameworks. That makes me wonder: are they a good idea and if they are not, why not?
Reusing code from multiple projects is in general a good idea. It reduces the need to maintain multiple different sets of code and makes it easier to implement functionality quickly.
I would create a repo specifically for those components and simply pull it into your codebase as a plugin. As for how to structure this component its identical to any other gem available on github , providing you namespace items correctly you can port it easily between applications without issue.
