Composer is a dependency manager and has other different uses. Composer is used to install packages while resolving dependencies. Composer is also very good at auto-loading. There are more uses of as well. Here, we will discuss the different uses of Composer.
Composer is a dependency manager. Now you can package your in a way that you don't need to ship third-party dependencies with it. You just need to tell its dependencies. In fact, your package dependencies can have more dependencies, and those dependencies can also have more dependencies. So, resolving all those dependencies while making a package or bundle could be really tiresome. But it is not, thanks to Composer.
Since is also a dependency manager, dependencies are not a problem anymore. We can just specify dependencies in a JSON file, and those dependencies are resolved by Composer. We will look into that JSON file shortly.
