Slow composer speed, or the ability to install one lib?

Question

Composer

Good day. I've been using composer for a few months now and I can't figure out why it's so slow.
for example. I have projects. I have already installed all the libraries that are in composer.json. After some time, I need to add 1 library. I copy it to composer.json and do composer insatll again. But the library is not installed as composer.lock. Now I have 2 options, delete this file, and run the installation again. Or do a composer update. In both cases, this process takes a very long time. For the sake of installing 1 library, you have to put it on update, and wait (smoke) for 10-15 minutes until composer does something.

Is there any way to install one library added to composer.json without affecting this long process?

Answer 1

Long because the composer checks all package dependencies, and packages have many more dependencies, as a rule.
If you need to update one lib, use:
You can also add the "--prefer-dist" parameter, then composer will try to install the lib from the archive, and not clone the repository.
