I am making SharePoint Hosted app while deploying this app it takes much time to deploy it around 15 min to uninstall and 15 min to install it.

SPFastDeploy deploy tool to quickly update your files. Its basically as Visual Studio extension which will allow you to update your artefacts instead of installing and uninstalling the SP hosted app everytime there is some change in code.
Once you install it, you will get an image as below. Once you click on it, your artefact will be deployed and updated:
