When comparing Yarn vs just-install, the Slant community recommends Yarn for most people. In the question“What are the best Windows package managers?” Yarn is ranked 10th while just-install is ranked 13th. The most important reason people chose Yarn is:
One of the most important aspects of Yarn is determinism (predictability). The lock file ensures that the same dependencies will always be installed in the same way and order regardless of the machine for a given repository.
Question Ranking
Pros
Pro The same results will be yielded every time yarn is run in a repository
One of the most important aspects of Yarn is determinism (predictability). The lock file ensures that the same dependencies will always be installed in the same way and order regardless of the machine for a given repository.
Pro Can tell you why a package was installed
yarn why <query> can tell you why a package was installed and what other packages depend on it.
Pro Good network performance
Yarn efficiently queues up requests and avoids request waterfalls in order to maximize network utilization.
Pro Offline mode
If you've installed a package before, you can install it again without any internet connection.
Pro Flat Mode
Resolve mismatching versions of dependencies to a single version to avoid creating duplicates.
Pro Multiple registries
Install any package from either npm or Bower and keep your package workflow the same.
Pro Network resilience
A single request failing won't cause an install to fail. Requests are retried upon failure.
Pro Good documentation
It looks like it has good documentation.
Pro Security is put at the forefront
Even though it's still in its early stages of development, security is one of the core values on which Yarn is built. It uses checksums to verify the integrity of every package before executing its code. This also helps avoiding errors related to faulty caching or captive portals.
Further steps are also being taken to improve the security of Yarn which will be implemented in the future.
Pro Built by the community for the community
Even though it's backed by Facebook, Yarn is built as a community project first and foremost. It's completely open source and hosted on Github. It's released under a standard open source client and has its own GitHub organization and set up to work under the same governance model that other successful projects have used in the past, such as Rust and Ember.
All of this means that both existing and new contributors will always work together to improve the product and introduce new features while also keeping in mind suggestions coming from the community.
Pro Backed by Facebook and Google
Was created in a collaboration of Facebook with Exponent, Google and Tilde.
Pro Open source, free and libre
Pro Works within Windows guidelines
The programs are listed in Control Panel and can be uninstalled using standard Windows procedure. Downloads from original source, doesn't repackage. It just automates the install process, skipping prompts and dialogs.
Pro Can install bundles, without needing command line parameters
Like Ninite, you can create a custom .exe installer which automatically downloads and installs a package selection -- no command line switches needed. https://just-install.it/customizer.html
Cons
Con Takes up disk space
Yarn adds to your disk space usage since it stores dependencies locally.
Con Limited package selection
Since project is open source there is way to add new packages, but you'll have to figure out how to configure new package and submit pull request. There's no army of volunteers responding to requests.
Con Requires admin command shell, doesn't have built-in UAC.
