Where is Edge Microgateway installed?

I just downloaded edgemicro using the following command -

npm install edgemicro -g

I don’t know where it installed. How can I get the install location?

When you use npm with the global option (npm install -g edgemicro), the software is installed in

[prefix]/lib/node_modules/edgemicro. 

You can find the value of [prefix] with this command:

npm config get prefix

if you omit the “-g” option, is it installed somewhere else?
