Facebook recently announced the open source release of Yarn, a JavaScript package manager that provides a “fast, reliable, and secure” alternative npm client. According to the release, Yarn can install packages more quickly and manage dependencies consistently across machines or in secure offline environments. It has compatibility with both the npm and bower workflows, along with having a readable and minimal CLI output.
The post shows you how to get started, and it should be interesting if this catches on in the developer community outside of Facebook. Anyone tried it out yet?
