2. Create a RESTful API
Express +

3. Roadmap
• Express Overview
• MongoDB Overview
• Learn Express Route
• ODM MongoDB with Mongoose
• Handle CRUD for an item
• Use the proper HTTP verbs to make it RESTful (GET,
POST, PUT, and DELETE)
• Return JSON data

4. Getting Started
$ curl https://raw.githubusercontent.com/creationix/nvm/v0.23.3/install.sh | bash
$ source ~/.nvm/nvm.sh
$ nvm install v0.10.36
$ nvm alias default 0.10.36
Install and Setup
Install Node.JS using NVM [Node Version Manager] https://github.com/creationix/nvm
Install MongoDB on OS X
Install MongoDB with Homebrew : $ brew install mongodb

5. MongoDB
MongoDB is a document database that provides high
performance, high availability, and easy scalability.

Schema Less
Data strore in JSON-like documents with dynamic
Providing flexibity during the development process
Built-in Javascript :)

7. “Representational State Transfer (REST) is a software
architecture style consisting of guidelines and best practices
for creating scalable web services. REST is a coordinated
set of constraints applied to the design of components in a
distributed hypermedia system that can lead to a more
performant and maintainable architecture.”

What is REST

8. Express Apps
$ npm install
$ node server.js

9. Express Route
curl -i -X POST -H 'Content-Type: application/json' -d '{}' http://localhost:3000/user
curl -i -X PUT -H 'Content-Type: application/json' -d '{}' http://localhost:3000/user
curl -i -X DELETE -H 'Content-Type: application/json' -d '{}' http://localhost:3000/user
curl -i -X GET http://localhost:3000/user

10. MongoDB with MongooseJS
$ npm install —save mongoose

11. Create MongoDB Model

12. $ git clone git@github.com:aredo/express-rest-api.git
