Tell us what’s happening:
I tested the function of my code and it satisfies the requirement but it does not show that I complete the test after I put it in freecodecamp website. Can someone please help me check it? Thank you.
Your code so far
in server.js
‘use strict’;

app.use(cors());
app.use(’/public’, express.static(process.cwd() + ‘/public’));
app.get(’/’, function(req, res){
res.sendFile(process.cwd() + ‘/views/index.html’);
});
app.get("/api/hello", function (req, res) {
res.json({greeting: ‘hello API’});
