Using npm modules for clients

E.g. exposing jquery with Express:

app.use('/assets', [
    express.static(path.join(__dirname, 'node_modules', 'jquery', 'dist'))
]);

which allows the client to fetch /assets/jquery.js.

Configure a private registry

cat <<EOF > /etc/npmrc
registry=${PRIVATE_REGISTRY_URL}
_auth = $(echo -n "${username}:${password}"| base64 -w0)
email = [email protected]

EOF
