I want to install **package.json** for client side from my server side **package.json** as the server side is using node and client side is using angular 2 
directory structure

```
server-app

--bin

--node_modules

--package.json

--client-app

     --app

     --node_modules

     --package.json

```

now the problem is:

I have to run this command **npm install** from **server app folder** and also from **server-app/client-app** folder separately this will create deployment issues 

what I want is to run only one time **npm install** from i.e **server-app** and it will automatically install the server-app package.json and client-side-app 
package.json too.
Any help will be highly appreciated
