Generic script to publish modules to NPM. Calls npm test and npm run documentation to make sure tests pass and documentation is generated. Then increments build number, pushes to Git and publishes on NPM. Lots of command line flags.

publish.sh

#!/bin/bash

VERSION=`node -e "console.log(require('./package.json').version)"`
ORIG_VERSION=$VERSION

MESSAGE="Commit for version v$VERSION"

MAJOR=false
MINOR=false
PATCH=false
UPREV=false

PUSH=true
PUBLISH=true

THIS_FOLDER=`pwd`

Showhelp () {
  echo "./publish.sh <options>"

  echo "    -h or --help - Show this screen"
  echo "    -v <version> or --version <version> - Set the version number explicitly"
  echo "    -M or --major - Increment Major version number, reset minor and patch"
  echo "    -m or --minor - Increment Minor version number, reset patch"
  echo "    -p or --patch - Increment Patch version number"
  echo "    --msg or --message - Set the commit message, if not supplied version will be used"
  echo "    --nopush - Don't push the changes to git"
  echo "    --nopublish - Don't publish on NPM"
  echo "    version - Output current version number"
