Should I use yarn?

Myles Borins (@thealphanerd) recently ran citgm with yarn, and shared the results. It was 25 minutes faster than npm, but 20 modules failed to install. Yarn is not a drop in replacement.

Some areas where issues arise:

• Reliance on npm-shrinkwrap.json
• Private modules on npm
• Modules backed by self-signed certificates
• Exotic dependencies declarations like .zip or shorthand urls
• Edge case issues on specific OSes, like Windows
• Pre- and post-script hooks don’t work like they do in npm
• Scripts that rely on npm environmental variables
