Michael Cook
Full Stack JavaScript Techdegree Graduate 28,975 PointsDon't use body-parser
This course needs updating. You do not need to install anything to get the body with Express, at least not any more. You can use Express's own middleware to do this:
// middleware for parsing http payloads
app.use(express.urlencoded());
app.all('/hello', (req, res) => {
console.log(req.body)
res.render('hello', { name: req.body.username });
});
Also, since the /hello route uses both GET and POST it makes a lot more sense to use Express's express.all method which responds to all http verbs rather than having two separate routes for GET and POST. Again, update the course please.

The express docs for express.urlencoded([options]) state: "This middleware is available in Express v4.16.0 onwards."
So either way, use the middleware from the video, or make sure to update your express version before trying this suggestion

23,932 PointsI was just reading the express docs. As of Jun-19-2020 express 5.x is still in the early stages of testing and isn't fully released yet. It's only in alpha mode. Your comments are appropriate for 5.x but personally, for now, I'd prefer following how Andrew Chalkley has laid out the lesson.

Full Stack JavaScript Techdegree Graduate 17,754 PointsI might be late but express.urlencoded() and get.all() are both part of express 4.x now

Full Stack JavaScript Techdegree Graduate 17,705 PointsI can't get app.all(); to work with cookie-parser. I had to use app.post(); and app.get();. Any thoughts on this?
