This assumes you have a working setup.
Since this work is released on NPM on https://firstname.lastname@example.org/dnn-sxc-angular, this is how you should work once a new release is ready:
npm run build
npm publish --dry-run
npm publish --tag beta
Note that this will only work if you have an npm-account with the correct permissions, mapped to this project.
