For development you can add variables in local.settings.json :

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "",
    "FUNCTIONS_WORKER_RUNTIME": "node",

    "host": "localhost",
  }
}

And use it with : 

process.env["host"]

For production you can add a Configuration of the Application in :

And this will override the variables in local.settings.json

Azure Functions provide us with a local.settings.json file where we can define these variables.

{
  "IsEncrypted": false,
  "Values": {
    "FOO": "-- Your Value --",
  }
}

You can access it from your code using process.env["FOO"]

Refer official docs

If you want the settings post deployment, when you publish the function use the --publish-local-settings -i switch during publishing.
