6. What is? • Put it simply, REST = REpresentational State Transfer , is an architectural style define to help create and organize distributed system. • It is not a guideline, not a standard, or anything that would imply that there are set a hard of rule to follow 3 PART 2 1 • There is no Request for Comments (RFC), which can leads to a widespread incomplete REST ideal • But have set of contraints to define uniform interface: Client-Server, Stateless, Cacheable, Uniform Interface, Layered System, Code-on-Demand
7. Why? • Performance, communication style is meant to be efficient and simple 3 PART 2 1 • Scalability, simple interaction greatly allow to handle heavy interaction • Modifiability, separation of concerns allow to minimize risk • Portability, can be implemented and consumed by many type of technology • Reliability, allows for the easier recovery of system after failure
8. How it works? (Resources) • Representations 3 PART 2 1 • Identifier • Metadata • Control Data
9. How it works? (Resources) • Representations, it can be any way of representing data (binary, JSON, XML, etc) 3 PART 2 1 • Identifier • Metadata • Control Data
10. How it works? (Resources) • Representations 3 PART 2 1 • Identifier, a URL that retrieves only one specific resource at any given time • Metadata • Control Data
11. How it works? (Resources) • Representations 3 PART 2 1 • Identifier • Metadata, Content-type, last-modified time, and so forth • Control Data, is-modifiable-since, cache-control

13. PART 3 4 2 What is? • LoopBack framework is a set of Node.js modules that you can use independently or together to quickly build REST APIs • Interacts with data sources through the LoopBack model API, available locally within Node.js, remotely over REST, and via native client APIs for iOS, Android, and HTML5 • Apps can query databases, store data, upload files, send emails, create push notifications, register users, and perform other actions provided by data sources and services. Introduction
14. PART 3 4 2 What is? Architecture
15. • Create dynamic end-to-end REST APIs with little or no coding PART 3 4 2 Why we use? • Access data from various data source: major relational databases, MongoDB, SOAP and REST APIs • Incorporate model relationships and access controls for complex APIs • Separable components for file storage, third-party login, and OAuth 2.0 • MIT open-source license
16. PART 3 4 2 Why we use? Loopback Express Sails Meteor Type API Framework HTTP server library Web MVC framework Full-stack JavaScript app platform Top Features Enterprise connectivity, API Explorer, generators, client SDKs, websocket microservices HTTP routing, middleware Rails familiarity, MVC Universal JavaScript, reactive rendering, websocket microservices Suitable For Web apps, APIs Simple web apps Web apps, APIs Web apps Clint SDKs Angular, Browser, Node.js, iOS, Android, Xamarin N/A None JavaScript, Cordova for iOS and Android, React, AngularJS Data Source In-memory/file, MongoDB, MySQL, Oracle, PostgreSQL, SQL Server, ATG, Email, REST, SOAP, many more. None In-memory, File, PostgreSQL, MySQL, MongoDB MongoDB, MySQL and PostgreSQL via 3rd-party packages ACLs Yes No No Basic allow/deny Comparation
17. PART 3 4 2 Why we use? “By using LoopBack, we can build REST API easily with little or no coding, connect to various datasources and define model relationship & its control access.”
18. PART 3 4 2 How it works? Core Concepts (Modules)
19. PART 3 4 2 How it works? • Models : Dynamically mock-up models and expose them as APIs without worrying about persisting (some) Key Features • Abstraction : Connect to multiple data sources or services and get back an abstracted model with CRUD capabilities independent of backing data source. • Data : Enable connections to RDBMS and noSQL data sources and get back an abstracted model • ACL : Controls if a principal can perform a certain operation against a model. • Remote Method : exposed remote method over a custom REST endpoint to perform operations not provided by LoopBack’s standard model REST API • Remote Hook : executed before or after calling a remote method, either a custom remote method or a standard CRUD inherited from PersistedModel
20. PART 3 4 2 Getting Started • Install : Install the LoopBack CLI tool $ npm install –g loopback-cli • Create App : Create a “Hello World” LoopBack application $ lb • Create Models : Generate models through CLI $ lb model • Run : Run as you would any Node application $ node . • Explore : Enables you to exercise all generated API endpoints http://127.0.0.1:3000/explorer
