Introducing YelpCamp Final Project

This is the beginning of building a single large application.
Here is an overview of what I will be building.
The purpose of YelpCamp is a place to find campgrounds and review them similar to how yelp functions.
The app will consist of a homepage/cluster map/authentication/create new campground post/review page

The code to get started:

Colt / YelpCamp

must run npm install to add the node modules dependencies

Creating the Basic Express App

At the terminal type

npm init -y

then install express, mongoose, and ejs

npm i express mongoose ejs

Then set up the additional file structure that will build out this project.

Campground Model Basics

Setting up a mongoose model for the campgrounds.
Each campground will have a name/title, price, description and a location.


const mongoose = require('mongoose'); 
const Schema = mongoose.Schema; 

const CampgroundSchema = new Schema({
    title: String, 
    prince: String, 
    description: String, 
    location: String
  }); 

mondule.exports = mongoose.model('Campground', CampgroundSchema);

Then the next thing is to make sure that mongoose is connected and functional.

Seeding Campgrounds

Now it is time to set up the campgrounds with data.
Here is where to find the data set to seed the database with.
https://github.com/Colt/YelpCamp/blob/c12b6ca9576b48b579bc304f701ebb71d6f9879a/seeds/cities.js

Campground Index

Now time to set up basic routes and templates functionality.


setting up the route 
app.get('/campgrounds', async (req,res) => {
  const campground = await Campground.find({})
  res.render('campgrounds/index')
 })

setting up the html template


<h1>All Campgrounds</h1> 
<ul> 
  <% for (let campgrounds of campgrounds %> 
<li><%= campgrounds.title %></li>
  <% }%>
</ul>

Campground Show

The show route will eventually become a details page for the campgrounds.

setting up the route


app.get('/campgrounds/:id', async(req, res) => {
    res.render('campgrounds/show')
 })

setting up the html template


<h1><%= campground.title %></h1> 

<h2><%= campground.location %></h2>

Campground New and Create

Rendering a form


<form action="/campgrounds" methods="POST">
  <div>
   <label for="title">Title</label> 
   <input type="text" id="title" name="campground[title]">
  </div>
  <div>
   <label for="location">Location</label> 
   <input type="text" id="location" name="campground[location]">
  </div>
<button>Add Campground</button>
</form>

setting up the route


app.post('/campgrounds', async (req, res) => {
  const campground = new Campground(req.body.campground); 
  await campground.save(); 
  res.redirect(`/campgrounds/${ campground._id }); 
 });

Campground Edit and Update

The route that serves the form


app.get('/campgrounds/:id/edit', async(req, res) => {
  const campground = await Campground.findById(req.params.id) 
  res.render('campgrounds/edit', { campground })); 
})

html template

<h1>Edit Campgrounds</h1> 
<form action="/campgrounds" methods="POST">
  <div>
   <label for="title">Title</label> 
   <input type="text" id="title" name="campground[title]">
  </div>
  <div>
   <label for="location">Location</label> 
   <input type="text" id="location" name="campground[location]">
  </div>
<button>Add Campground</button>
</form>

Campground Delete

The route will be a delete route


app.delete('/campgrounds/:id', async (req, res) => {
   const { id } = req.params; 
   await Campground.findByIdAndDelete(id);
res.redirect('/campgrounds');
})

html template


<h1><%= campground.title %></h1> 
<h2><%= campground.location %></h2>

<p> <a href="/campgrounds/<%=campground_id%>/edit">Edit</a>
</p>
<p>
<form action="/campgrounds/<%=campground._id%>?_method=DELETE" method="POST"> 
<button>Delete</button>
</form>
</p>
<footer>
<a href="/campgrounds">All Campgrounds</a>
</footer>

Now that the basic structure is set up, it is time to build out the complexities of the yelp camp web application.
