20,084 PointsI am following the video but get a 'Cannot GET /' on my localhost:3000
const express = require('express');
const app = express();
app.get('/greetings', (req, res)=>{ // get takes 2 argument, first - the route we want to handle, second - callback function how we want to respond
res.json({greeting: "Hello World!"}); //json in object
}); //because we build a rest api, we want to send back json instead of res.render('some_html_template')
app.listen(3000, () => console.log('Quote API listening on port 3000!'));

In the video we aren't' handling any GET request to "/". We only handle GET requests to "/greetings". You would have to go to localhost:3000/greetings to see anything.
Check out the course Express Basics for some great information on this!

Is your app running (did you run npm start or nodemon in the console)?
