+# Rush uses this file to configure the NPM package registry during installation.  It is applicable
+# to PNPM, NPM, and Yarn package managers.  It is used by operations such as "rush install",
+# "rush update", and the "install-run.js" scripts.
+#
+# NOTE: The "rush publish" command uses .npmrc-publish instead.
+#
+# Before invoking the package manager, Rush will copy this file to the folder where installation
+# is performed.  The copied file will omit any config lines that reference environment variables
+# that are undefined in that session; this avoids problems that would otherwise result due to
+# a missing variable being replaced by an empty string.

+# It is NOT recommended to store authentication tokens in a text file on a lab machine, because
+# other unrelated processes may be able to read the file.  Also, the file may persist indefinitely,
+# for example if the machine loses power.  A safer practice is to pass the token via an
+# environment variable, which can be referenced from .npmrc using ${} expansion.  For example:
+#
+#   //registry.npmjs.org/:_authToken=${NPM_AUTH_TOKEN}
+#
+registry=https://registry.npmjs.org/
