WHAT IS REST API• REST : Representational State Transfer• was defined by Roy Thomas Fielding in his 2000 PhD dissertation

"Architectural Styles and the Design of Network-based Software Architectures".

• It relies on a stateless, client-server, cacheable communications protocol -- and in virtually all cases, the HTTP protocol is used. (http://rest.elkstein.org/)

REST CONSTRAINTS• Client–server• Stateless• Cacheable• Uniform Interface

REST METHODS• GET• POST• PUT• DELETE

NODEJS• JavaScript runtime built on Chrome's V8 JavaScript engine. Node.js uses an

event-driven, non-blocking I/O model that makes it lightweight and efficient.

EXPRESS• is a minimal and flexible Node.js web application framework that provides a

robust set of features for web and mobile applications.

MONGOOSE• Elegant mongo DB object modeling for node.js

EXPRESS ROUTE (2)• Create route for path / with POST method to insert new data

EXPRESS ROUTE (3)• Create route for path /:id with GET method to get data by ID

EXPRESS ROUTE (4)• Create route for path /:id with PUT method to update existing data with new data by ID
