Is It a Good Idea to Start From Scratch?

Libraries, a p is and micro services everywhere where you can literally grab building blocks off the shelf as you're holding something at home. The cool thing about these things is that they're built by other developers who know what our main pain points are. I think people usually like to turn to the whole like olin's store, example, because that's easier to understand. But if you're using an outside service to handle your authentication and all that kind of stuff, and they change something, and it's a breaking change, that ruin, like, your whole store,. so you can't even buy anything.
