Basic Node and Express - Use the .env File

Challenge: Basic Node and Express - Use the .env File
Hi sorry to ask. I am struggling here. Even examples I have seen make no sense of this. It will not be capitalised but I have lost the thread of why MESSAGE_STYLES appears tagged on the back of process.env
Link to the challenge:

freeCodeCamp.org

let MESSAGE_STYLE = "Hello json";
if (MESSAGE_STYLE ==="Hello json".toUpperCase()){
  MESSAGE_STYLE = "HELLO JSON" ;
  }else{
  MESSAGE_STYLE;
  };
app.get("/json", function(req, res){ 
process.env.MESSAGE_STYLE(__dirname +  MESSAGE_STYLE)
});

“process.env.MESSAGE_STYLE” is a dot notation to refer to the enviroment variable “MESSAGE_STYLE” which is a property of the object “process.env”.

“process.env” holds all the values of environment variables as properties of the object, thus you need to refer to the variable with the dot notation “process.env.MESSAGE_STYLE”.
This reference to the variable is only for reading the value “uppercase” in your script.

If you want to declare the variable and store the value “uppercase”, do as follows:
if you are using replit you need to use secret tabs to store this variable.
If running project locally, store it in a “.env” file.
Don’t store the variable by declaring let message=“uppercase”, it doesn’t work for environment variables.

you can view the link provided by the hints here for the answer.

freeCodeCamp Challenge Guide: Use the .env File

Use the .env File Problem Explanation We can use the .toUpperCase() method to make a string all caps, such as: var response = "Hello World".toUpperCase(); // now becomes "HELLO WORLD" All we need to do now is check what the value of the environment variable is, which you can do like: if (process.env.VAR_NAME === "allCaps") { response = "Hello World".toUpperCase(); } else { response = "Hello World"; } NOTE: Ensure the fcc-express-bground package in your package.json file is pointing to t…

i am not able to find the problem can you help me here is my code :
const express = require(‘express’);
const app = express();
const path = require(‘path’);
const mySecret = process.env.MESSAGE_STYLE;

app.get(‘/’, (req, res) => {
res.sendFile(path.join(__dirname, “views”, “index.html”));
});

app.use(‘/public’, express.static(path.join(__dirname, ‘public’)));

app.get(“/json”, (req, res) => {
if (mySecret === “uppercase”) {
res.json({ “message”: “HELLO JSON” });
} else {
res.json({ “message”: “hello json” });
}
});

module.exports = app;

@w3nch It would be better if you open a new thread when you have questions.

Anyway, process.env.MESSAGE_STYLE needs to be evaluated inside the route handler for the tests to work.
