bash script to manually publish a public package to your private npm Enterprise registry

replicate-package.sh

#!/usr/bin/env bash

trap 'exit' ERR

for PACKAGE
do
    echo "$PACKAGE"

    # download and extract tarball for latest version
    curl `npm info $PACKAGE dist.tarball --registry https://registry.npmjs.org` | tar xz

    # run this script with NPME_REGISTRY=http://reg.myco.com:8080
    # or make sure ~/.npmrc points to your private registry by default
    if [[ "x$NPME_REGISTRY" != "x" ]]
    then
      npm publish package --ignore-scripts --registry $NPME_REGISTRY
    else
      npm publish package --ignore-scripts
    fi

    # cleanup extracted tarball contents
    rm -rf package
done

echo "success!"

FYI: npm can publish a tarball directly, so you can skip unpacking it just to have npm immediately pack it again. Also the npm pack command can download a package for you, and helpfully dumps the filename that it downloaded to stdout:

#!/usr/bin/env bash
set -e

for package in "$@"; do
  file="$(npm --registry=https://registry.npmjs.org pack "$package")"
  if [ -f "$file" ]; then
    npm publish "$file"
  else
    echo "Failed to download $package" 1>&2
  fi
done
