This document discusses how to create a REST API in Node.js using the Express framework and Mongoose ORM for connecting to MongoDB. It begins with an introduction and background on REST APIs and the technologies used. It then walks through setting up dependencies, creating basic Express routes, connecting to MongoDB with Mongoose, defining a schema and model, and using the model for CRUD operations. The document ends with instructions on testing API endpoints in Postman and includes a link to the source code repository.

1. CREATE REST API IN NODEJS

3. 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/)

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

5. REST METHODS
• GET
• POST
• PUT
• DELETE

6. 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.

7. EXPRESS
• is a minimal and flexible Node.js web application framework that provides a
robust set of features for web and mobile applications.

8. MONGOOSE
• Elegant mongo DB object modeling for node.js

10. SET UP DEPENDENCIES

11. BASIC REST IN EXPRESS
• Require express framework
• Create app
• Our very first API
• And check it

12. CONNECT MONGODB WITH MONGOOSE
• Require mongoose
• Create connection
• You can add handler state

13. CREATE MODEL IN MONGOOSE
• Require connection
• Create schema
• Create model

14. USING MODEL AS ORM
• Require model
• Save data using ORM

15. EXPRESS ROUTE (1)
• Require express and get router instance
• Require model for ORM usage
• Create route for path / with GET method to get all data in database

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

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

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

19. EXPRESS ROUTE (5)
• Create route for path /:id with DELETE method to remove data by ID
• Create root path for all your API

20. TEST IN POSTMAN (1)

21. TEST IN POSTMAN (2)

22. TEST IN POSTMAN (3)
