How do I specify instance class for the Node.js standard environment?

How do I configure F2 instance instead of the default F1 instance?

Hello Mani, 

Under the "Runtime and app elements" subtitle of the "app.yaml Configuration File" documentation page, you may have a look at the "instance_class" sub-chapter, to get needed information on configuring an F2 instance class for your service. The procedure looks similar, whether for node.js or other programming environments: you just need to configure your app by means of the app.yaml configuration file.
