It was a great idea to use git and create portal like GitHub and share source code among other developers. One of the benefits is, you do not need to reinvent the wheel and just use package you need. And because lot of users will add it to their projects, it gets well tested. But I can see there a big problem: maintenance.
I am working on React app with couple of other developers. And you know it, you need this component, that functionality, etc. so you google it, install the package and the work is done. Is it ok to work like this? Do you even know what exactly you added to your project and do you really need it?
