Publish an npm package to efficient code sharing & reuse between services.

Steps:

1. Create an npm organization within your account (other option available, see npmjs.org).
2. Create a directory that contains common code.
3. Move to the newly created dir and run npm init.
4. Run npm login and follow the steps (if required).
5. Initialize git repo & commit changes.
6. Run npm version patch before publishing a new version.
7. Run npm run build to build the code.
8. Run npm publish --access public to publish. Before doing so, make sure adjustments have been made in package.json.
9. Run npm update <package name> to update the version wherever it is being used.
