I am learning NodeJS and I need to know how to set my production environment using process.env.___ .When I run

console.log(app.get('env')); //app is express object

I get output on command prompt development as environment. But if I try to set an environment variable eg. process.env.NODE_ENV, on command prompt I write :set NODE_ENV=productionand then again try : console.log(process.env.NODE_ENV); I get output: undefined. I've been struggling hard and searching online but have't got a solution yet.

Please, guide me in this matter.

    @MonkeyDLuffy, I just dug a little and found that in poweshell type $env:NODE_ENV="production". It did the work for me. Remember the dollar sign and quotes. Here is the source: stackoverflow.com/questions/9249830/… Commented Aug 21, 2018 at 10:11
