Chapter 7, 3rd code example under "Sections" header

While reading this book via Safari Books Online (macOS Chrome 80.x), I noticed that a code example in Chapter 7 is incorrect. This is the third code example under the "Sections" header prefaced with the sentence "Now in our layout, we can place the sections just as we place {{{body}}}:".

Looking at the GitHub repo of code examples, the GitHub code example is correct, but the one in book is not. The code on GitHub should be the code included in the book. Please see: https://github.com/EthanRBrown/web-development-with-node-and-express-2e/blob/master/ch07/views/layouts/main.handlebars

Enjoying the book. Thank you.

2nd paragraph (The setup code for the meadowlark.js file)

The setup configuration of the meadowlark.js file to use handlebars didn't work for me. The configuration that works for me involves using the ES module by adding the type field with the module value to the package.json file. Then change the setup to:

import express from 'express';
import {engine} from 'express-handlebars';

const app = express();
const port = process.env.PORT || 3000;

// configure Handlebars view engine
app.engine('handlebars', engine());
app.set('view engine', 'handlebars');
app.set('views', './views');

//Thank you for this beautiful book. It's the best book I selected out of many //others.

Note from the Author or Editor:
express-handlebars has changed it's packaging, and the current version has a different import structure. The version in the companion repository (^3.0.2) works as written. I will revise the text accordingly.

The text says one can change the "handlebars" extension to ".hbs" by passing an object "{extname: '.hbs'}" when creating the express-handlebars instance. This did not work for me.

The express-handlebars docs have an example:

app.engine('.hbs', exphbs({
extname:'.hbs',
defaultLayout: 'home',
helpers: {
section: function(name, options) {
if(!this._sections) this._sections = {}
this._sections[name] = options.fn(this)
return null
},
},
}));
app.set('view engine', '.hbs');

which does work.
