trying to pass env variables to deployed app

[w3jimmy]

Hi, I'm trying to pass env variables to the deployed app but I'm not succeeding.

I can deploy the app and run using the required server variables (ROOT_URL, MONGO_URL, PORT) butI have a few "switches" in my app where the code changes depending on a few server variables, for example: CUSTOM_DEBUG=true and API_HOST=xxx.xxx.xxx.xxx

Is there a way to do this? And what is the correct way of doing so?

I've tried editing the final npm start script but didn't make any difference. Thanks

What platform are you running this on? The syntax is different on Windows

SET CUSTOM_DEBUG=true
SET ROOT_URL=http://localhost:8080
SET MONGO_URL=mongodb://localhost:27017/test
npm start

To do that in your start script do something like

{
  "start": "SET CUSTOM_DEBUG=true && SET ROOT_URL=http://localhost:8080 && SET MONGO_URL=mongodb://localhost:27017/test && node ../../main"
}

That works in cmd and PowerShell, but won't work the same if you are using the Git Shell.

It's also worth checking out cross-env if you need this to work in multiple environments.

thanks @fiveisprime. I'm running in Mac OS X. I will try this approach in the next few minutes

Ahh, on OSX, it looks like this

{
  "start": "CUSTOM_DEBUG=true ROOT_URL=http://localhost:8080 MONGO_URL=mongodb://localhost:27017/test node ../../main"
}

This is still not working for me. location: bundle/programs/server/

I tried: 1. CUSTOM_DEBUG=true ROOT_URL=http://localhost:8080 MONGO_URL=mongodb://localhost:27017/test node ../../main 2. CUSTOM_DEBUG=true ROOT_URL=http://localhost:8080 MONGO_URL=mongodb://localhost:27017/test && node ../../main 3. export CUSTOM_DEBUG=true ROOT_URL=http://localhost:8080 MONGO_URL=mongodb://localhost:27017/test && node ../../main

In all of the cases only CUSTOM_DEBUG is not being detected by the app

what could I be missing?

[fiveisprime]

That first one is correct. How are you testing for CUSTOM_DEBUG in your app?

[w3jimmy]

I finally made it work, but only using cross-env. Inside my app I access to it with process.env.CUSTOM_DEBUG

Weird, but glad you got it working!
