Pattern 0: Natal patterns
StrongLoop Confidential and Proprietary Information – © 2015
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
Pattern 1: Convention
Web Middleware REST API
Pros and Cons
StrongLoop Confidential and Proprietary Information – © 2015
u Pseudo-Opinionated, Express and Restify are DIY u Middleware u Strengths
u Express: Web templating, ecosystem u Restify: REST API
u Low learning curve u Restify: Dtrace and SPDY Support u Weakness
u Manual CRUD u Manual recursive Testing/Refactoring
Router in
Express

Pattern 2: Configuration
u Opinionated u Configuration over Convention u Granular HTTP/Webserver control u Good plug-in ecosystem u Supported and well documented u Weakness
u Manual CRUD/Refactor/Testing
u No plug & play with Express ecosystem

Pattern 3 : Full Stack JS

{“..”} JSON is the new first class citizen
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 Weakness
u Higher learning curve

API Economy driven by Mobile / IoT
Mobile and IoT explosion u Sheer number of clients has increased
u Clients are increasingly sophis.cated
u Node.js is the plaHorm of choice for these API

mBaaS
Mobile API tier
Enterprise
Pattern 5: mBaaS
mBaaS could be on cloud or premises
