Picking the Right Node.js Framework for Your Use Case
- 1. Shubhra Kar | Products & Education twitter:@shubhrakar Frameworks or a Design Pattern ?
- 2. About me u J2EE and SOA architect u Performance architect u Node, mBaaS & APIs
- 3. These guys sent me ! Bert Belder Ben Noordhuis Node/io Core Raymond Feng Ritchie Martori LoopBack & Express Core Sam Roberts Miroslav Bajtos Ryan Graham
- 5. No IO bottlenecksHighly Concurrent Very Fast JIT compiled Node.js is emerging as the answer Reduce infrastructure by 5XScalable Lightweight, JS back and front, HeadlessFull stack Write and maintain 50% lesser codeSimple Suited for mobile and IoTEvented & JSON Biggest OSS community on the planetEcosystem
- 7. Evolution is inevitable ! Thick Web SaaS Mobile IoT
- 8. Frameworks evolve as well ! • Callback • Reactor • Observer • Express • HAPI • Restify • Total • Partial • Loopback • Parse • Meteor • Feedhenry* • Loopback • Sails • Meteor • Geddy • Loopback • NodeRED • Proprietary KISS MVC MBaaS ORM/ MEAN Micro/ loT
- 9. Pattern 0: Natal patterns Philosophy: KISS (Keep It Simple Stupid) u small core u small modules u small surface area Patterns u reactor u callback u module u observer
- 10. Pattern 1: Convention HTTP Server Library REST HTTP Library Simple MVC Structure
- 11. Pros and Cons Express DIY HTTP Routing, Middleware, Templating Simple Web Apps Github Stars – 19K Commercial Support - StrongLoop CLI App Generator Export API definition with strong-remoting Connect/Express middleware extensions Vast Ecosystem and low learning curve StrongLoop DevOps tooling support Manual CRUD endpoints Manual recursive refactoring/testing No Data source Support No Client SDK No ACL (Fine Authorization) Restify DIY Simplicity, Rest Routing Simple REST API Github Stars – 3K Commercial Support - Joyent Yeoman Generator SPDY Support Dtrace Support No export of API definition No Data source Support No Extensions of significance Manual CRUD endpoints Manual recursive refactoring/testing Limited Ecosystem No ACL (Fine Authorization)

- 13. Router in Restify StrongLoop Confiden.al and Proprietary Informa.on – © 2015
- 14. Pattern 2: Configuration HTTP Server Framework Hapi Opinionated Modularity, Security, HTTP Server control Complex Web Apps, APIs Github Stars – 4K Commercial Support - None Yeoman Generator No export of API definition Hapi Plugins – Joi, bell, bassmaster, etc Limited ecosystem as compared to Express; but does support templates with plugins Swagger support for API documentation Very limited Data source support – Mongo, Postgres, leveldb No Client SDK No ACL (Fine Authorization)
- 15. Router in hapi StrongLoop Confiden.al and Proprietary Informa.on – © 2015
- 16. Pattern 3 : Full Stack JS à lends into pattern 4 {“..”} JSON is the new first class citizen
- 17. Pattern 4: ORM & Isomorphic JS u Model Driven Development u Any data source u Isomorphic JS u Omni-Channel u Share Models (Client/Server) u Loopback & Meteor u Automatic REST API generation, routing, etc u Common Weakness : Higher Learning Curve
- 18. Sails Opinionated Web MVC framework WebApps, API Rails familiarity, MVC Github Stars – 10 K (older) Commercial Support - None Yeoman Generator StrongLoop DevOps tooling support No export of API definition Limited data sources – MySQL, Mongo, Postgresql, memory/file No Extensions of significance Limited Ecosystem No ACL (Fine Authorization) No Client SDKs Pros and Cons
- 19. Loopback Opinionated API framework Complex Web Apps and APIs Modularity, Scaffolding, Enterprise Connectivity Github Stars – 4 K (newer) Commercial Support - StrongLoop CLI Code Generator, Visual API composer, API explorer Export API definition Extensions like Push, File Storage, Passport, Oauth 2.0, Express Middleware Vast Connector ecosystem and extend express Auto CRUD Swagger UI and Code Generator DataSources like Mongo, mySQL, Oracle, SOAP, REST, SQLServer, Memory/File, Postgresql, Email, ATG, Couchbase, Apache Kafka, and many ore Client SDK – Angular, Browser, IOS, Android, Node.js Mature ACL (Fine Authorization), API Gateway Pros and Cons

- 23. Sub-pattern : Schema Discovery
- 24. mobile/web clients social & analytics JSON API API XML SQL SOAP Etc. mBaaS Mobile API tier Enterprise Pattern 5: mBaaS
- 25. mBaaS could be on cloud or premises u Closed Source / Commercial u Open Source Key API u Push Notification u Geo Location u Offline Sync u Storage u User Management u Metering, Analytics u Native SDK u Isomorphic JS

- 28. Push Notification in Loopback
- 29. Wait …what is this API Gateway Thing then ?
- 30. Synchronous API “Re-Composition” is an anti-pattern
- 31. Security & Social Logins Why not an node.js API Gateway pattern ? Pattern 6 API Clients API Gateway API Server API
- 32. Internet of Everything The devices are taking over !!! Microsecond latencies are the norm
- 33. API “Decomposition” is the game changer {JSON} {JSON} {JSON}<SOAP/XML> <TABLE> Web SaaS Mobile loT HTML JSON App Server API Server
- 34. Is micro services a pattern too ? Not just infrastructure virtualization !
- 35. Pattern 7: Micro-services (Design Time) Client SDK REST Endpoints Store Cache API Micro Services One URL Space SL API PaaS REST/JSON API Gateway Router Remoting Model API Orchestrator Cloud Services Model Model Connector Connector Connectors
- 36. Pattern 8: Micro-services (Run Time)
- 37. Now I know !!!
- 40. First there was Node Thank you! JUST WIN, BABY!
