Use composer as a class management tool in the development environment. After the code is written, does the production environment also require Composer as a management tool?

As the question. I don't know how Composer is managed. If you use Composer as a management tool in the development environment, do you still need to use Composer after you write the code and put it in the production environment (for example, the virtual host I bought? If not, for example, virtual space cannot be installed. I don't know how Composer is managed.

Composer is only a package management tool. It is not necessarily related to unfamiliar Code. It is only convenient to use it. You can also download the code of other people's homes and get it by yourself, same as usual.

It doesn't have to be, but it's a bit of a hassle that the vendor files in your local project are also uploaded to the space, which is too slow and too troublesome.
