How do we tell iisnode to run our Node.js application environment in production/development/test?
We have successfully gotten our Node.js app running with iisnode but process.env.NODE_ENV is coming out as 'undefined'.
At the moment, our web.config file is written this way:
<configuration>
<system.webServer>
<handlers>
<add name="iisnode" path="app.js" verb="*" modules="iisnode" />
</handlers>
<rewrite>
<rules>
<rule name="app">
<match url="/*" />
<action type="Rewrite" url="app.js" />
</rule>
</rules>
</rewrite>
<security>
<requestFiltering>
<hiddenSegments>
<add segment="node_modules" />
</hiddenSegments>
</requestFiltering>
</security>
</system.webServer>
<appSettings>
<add key="NODE_ENV" value="production" />
</appSettings>
</configuration>

You can signal Node. js that you are running in production by setting the NODE_ENV=production environment variable. in the shell, but it's better to put it in your shell configuration file (e.g. . bash_profile with the Bash shell) because otherwise the setting does not persist in case of a system restart.
Use echo $NODE_ENV . The command line is a shell, probably bash and that's the bash syntax to print the value of an environment variable.
NODE_ENV is an environment variable that stands for node environment in express server. The NODE_ENV environment variable specifies the environment in which an application is running (usually, development or production).
Joachim is right above that adding <iisnode node_env="production" /> to web.config allows control over the NODE_ENV value. Another way is to add the iisnode.yml file next to your web.config, and in there spcify the NODE_ENV value as node_env: production. See other settings you can use in iisnode.yml at https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/iisnode.yml
