I am bit confused about commands composer init' and composer require
If I am correct:
requireinitI have a project and I do NOT want to publish it to https://packagist.org/
I just want to add some libraries to my project.
Do I have to necessarily run composer init before I run composer require?
I watched a tutorial, where they use composer init command before calling composer require, which confused me, because I though that composer init was related to publishing a library on packagist.
composer init just creates an "empty" composer.json, asking you some questions to fill out boilerplate.
No, it's not a necessary command "to publish a package", just a helper to initialize a project. That project can either be an package or stand-alone project.
require adds a package to an existing composer.json, and if the composer.json file does not exist in that directory it will just creates a blank one for you.
So calling composer init is certainly not required before running composer require package-name, but it simply helps you have a more fleshed out composer.json to start with.
