let express = require(‘express’);
let app = express();

if(process.env.MESSAGE_STYLE === ‘uppercase’){
let response = “Hello json”.toUpperCase();
app.get("/json", function(req, res){
res.json({“message”: response});

})
}else{
app.get(’/json’, function(req, res){
res.json({“message”: “Hello json”});

})
}
app.use("/public", express.static(__dirname + “/public”));

app.get(’/’, function(req, res){
res.sendfile(“views/index.html”)

It is best to post actual code instead of a picture.

let express = require('express');
let app = express();


if(process.env.MESSAGE_STYLE === 'uppercase'){
  let  response = "Hello json".toUpperCase();
  app.get("/json", function(req, res){
  res.json({"message":  response});
  
})
}else{
  app.get('/json', function(req, res){
  res.json({"message": "Hello json"});
  
})
}
app.use("/public", express.static(__dirname + "/public"));


  app.get('/', function(req, res){
  res.sendfile("views/index.html")
let express = require('express');
let app = express();


if(process.env.MESSAGE_STYLE === 'uppercase'){
  let  response = "Hello json".toUpperCase();
  app.get("/json", function(req, res){
  res.json({"message":  response});
  
})
}else{
  app.get('/json', function(req, res){
  res.json({"message": "Hello json"});
  
})
}
app.use("/public", express.static(__dirname + "/public"));


  app.get('/', function(req, res){
  res.sendfile("views/index.html")
  
})

 module.exports = app;

The if statement needs to be inside the route handler.

You are determining when the app starts what the response will be. This means that your app can’t respond to changes in the environment variable. Your logic for changing the response based upon the environment variable needs to be inside of the GET.
