i have a command tool application developed using node. when pointed over a folder when i run a command it should install the node dependencies specified in the package.json file in the folder. is it possible to do like this.
You need to use
exec = require('child_process').exec;
exec(#your command starts here
But in general you should do googling before asking questions: http://nodejs.org/api/child_process.html
also remember that user under which your tool is executed should have access rights to do so (e.g. root or destination folder owner)
