.env not identified with Repl and not working on others

JavaScript

Welcome there,

I am not sure what you are experiencing in Replit, as I cannot replicate any issues. Also, I am not sure what your Glitch code is, but with the code you linked to there is an issue:

var response;
if (process.env['MESSAGE_STYLE'] === "uppercase") {
  response = "Hello json".toUpperCase();
} else {
  response = "Hello json";
}
app.get('/json', (req, res) => res.json({"message": response}));

Consider when the code runs:

  1. Node application starts:
  • All variables are defined (e.g. response = "HELLO JSON")
  • All routes are attached to app
  • All callbacks are defined for what should happen if a route is reached
  1. Now, a route is requested (e.g. /json):
  • The route has been defined to respond with some form of response whatever its value is
  • response is still "HELLO JSON"
  1. The environment variable is changed (the fCC tests do this for you)
  • The script is still running from previously, so response is not redefined/changed
  • The route res is always the same

Hope this helps
