# Whilst in theory yarn's checking of the node/yarn version against the `engines` property
# in package.json  is a great idea, in practice it causes unnecessary confusion/hassle for
# contributors, since most node/yarn versions will work fine with Treeherder anyway.

# `--no-bin-links` is required when using Vagrant on Windows hosts (where symlinks aren't
# allowed), and so we include here to ensure that the package.json scripts aren't relying
# on symlinks that won't exist elsewhere. This alternate config form is required due to:

# Don't run preinstall/install/postinstall hooks during yarn install, since:
#  - most are not actually required
#  - they often don't work with --no-bin-links (the bin scripts called may not exist)
#  - they cause Yarn to "unplug" the package when using the "Plug and Play" feature
#  - it's more secure to not run arbitrary code during package installation

# Default to saving the exact package version in package.json and not a tilde version range.
