How to store third party libraries in git?

Question

git

Good afternoon.

There is a project that requires yii, extjs, angular and bootstrap to work. The project is developed using git.
Tell me, is it worth including third-party library files in the repository or should they be excluded?
If they are excluded, it seems to me that when cloning the repository, it will be somewhat stressful to separately download and install all the dependencies. Plus, often the version of the libraries also matters, and, say, in a year, the current version will be difficult to find.

Tell me, do you include third-party libraries in the repository?

And one more question:
The project is written in Coffeescript. As I understand it, js files should be excluded and compiled after cloning the repository. I'm right?

Thanks in advance for the replies.

Answer 1

Of course turn it on. This is usually put in the vendor folder.
Most importantly, don't touch the submodules in git - it's so ... buh.

Answer 2

Use composer
