How to understand deployment?

Question

PHP

Hello.
I am writing my small project in PHP as a training.
I want to correctly deploy it to the server.
But there is some misunderstanding:
1) I use a composer to download the library from the github that is used in the project
2) I prescribe in the gitignor so that the library is not uploaded to the repository of my project
3) I upload the project to git
4) I will make a git clone on the server, the project files will be loaded ( which I wrote), but there is no library.
Would it be correct for the composer on the server to download the library to the project folder or upload all files to the github, including the library?

Answer 1

First.
There are many libraries, including dev dependencies that are needed only for development.
You can also read about CI/CD and the automated deployment process from git to your server.
