Updating the routes and putting them in their own campgrounds.js file
const express = require('express'); const router = express.Router(); const catchAsync = require('../utils/catchAsync'); const { campgroundSchema } = require('../schemas.js'); const ExpressError = require('../utils/ExpressError'); const Campground = require('../models/campground'); const validateCampground = (req, res, next) => { const { error } = campgroundSchema.validate(req.body); if (error) { const msg = error.details.map(el => el.message).join(',') throw new ExpressError(msg, 400) } else { next(); } } router.get('/', catchAsync(async (req, res) => { const campgrounds = await Campground.find({}); res.render('campgrounds/index', { campgrounds }) })); router.get('/campgrounds/new', (req, res) => { res.render('campgrounds/new'); }) router.post('/campgrounds', validateCampground, catchAsync(async (req, res) Breaking Out Review Routes
Creating a reviews.js to put the review code in.
const express = require('express'); const router = express.Router(); router.post('/campgrounds/id:/reviews', validateReview, catchAsync(async (req, res) => { const campground = await Campground.findById(req.params.id); const review = new Review(req.body.review); campground.reviews.push(review); await review.save(); await campground.save(); res.redirect(`/campgrounds/${campground._id`); })) router.delete('/campgrounds/:id/reviews/:reviewId', catchAsync(async (req, res) => { const { id, reviewId } = req.params; await Campground.findByIdAndUpdate(id, { $pull: { reviews: reviewId } } ); await Review.findByIdAndDelete(reviewId); res.redirect(`/campgrounds/${id}`); })) module.exports = router; Configuring Session
session will be added to the main app.js file.
const sessionConfig = { secret: 'secretcode', resave: false, saveUninitialized: true, cookie: { httpOnly: true, expires: Date.now() + 1000 * 60 * 60 * 24 * 7, maxAge: 1000 * 60 * 60 * 24 * 7 } } app.use(session(sessionConfig)) 
Setting Up Flash
To display a quick message to the user that the data was successful. The message will disappear once the page has been reloaded/refreshed.
app.use(flash()); app.use((req, res, next) => { res.locals.success = req.flash('success'); res.locals.error = req.flash('error'); next(); }) Flash Success Partial
