YelpCamp

Launch Code
YelpCamp is a multi-user web app that I made to explore the power of Node.js, Express, MongoDB and npm packages. This app features secured user signup and login functions and allows logged-in users to post, edit and delete campgrounds. Users can also post, edit and delete comments for each campground. This app also features beautiful images which slow it down significantly since I'm using free database and server hosts.
  • Hosted on Heroku servers, Database hosted on mLab
  • Non-relational database (MongoDB), Mongoose for configuring MongoDB models
  • Node.js used as environment for writing server-side code
  • Express for handling RESTful routes
  • Method-Override for handling update and delete functions
  • EJS for templating
  • Passport.js for password hash and salt
  • Express-Sessions for configuring cookies
  • Flash messages to notify errors when User is redirected from a page
  • Bootstrap to provide responsive design that is great on mobile

Todo List

My To-Do List is a simple to-do list I made to practice jQuery. Users can create to-do items, check off items and delete items from the list--all without the use of a database. The power of jQuery was put to the test, allowing me to use minimal code to manipulate HTML elements.
