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.
Create Rest API in Nodejs
- 1. CREATE REST API IN NODEJS WITH EXPRESS FRAMEWORK AND MONGOOSE
- 2. ABOUT ME Name : Irfan Maulana Work in : PT Global Digital Niaga (Blibli.com) Position : Software Development Engineer + JavaScript Enthusiast + Specialize in Web Front-End + New knowledge addicted
- 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
- 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)
