- 1. Date: 02/03/2015 Frameworks or a Design Pattern ? Shubhra Kar, Head of Products and Education @shubhrakar
- 2. Bert Belder Ben Noordhuis Node Core Raymond Feng Ritchie Martori LoopBack / Express Core Sam Roberts Miroslav Bajtos Ryan Graham Plus 15 other full-time open source developers working on Node.js core, modules and tools. Contributing to over 100 open source modules. Supporting banks, retail, IoT companies, startups and internet companies on Node.js
- 3. Patterns are not created, they evolve Right Now — Someone on Stage
- 4. Pattern 1: DIY / Construction Blocks ✤ Un-opinionated ✤ Middleware
- 5. Router using express 4.0
- 7. Strengths andWeaknesses Pros Great starting point Low learning curve Nearly a standard for Node.js web middleware Fully customizable Targeted at browser, hence templating and rendering OOB Cons All endpoints need to be created manually Developers may end up creating their own non-optimized libraries Every end point needs to be tested Refactoring is painful, update everything everywhere No standards or prescription, DIY Pros Very stable and actively developed. Automatic DTrace support for all handlers on enabled platforms Built in throttling SPDY support Borrows from express but without unnecessary templating/rendering Strict API with full control over HTTP interactions Visibility into latency and app characteristics Cons All endpoints need to be created manually Developers may end up creating their own non-optimized libraries Every end point needs to be tested Refactoring is painful, update everything everywhere No standards or prescription, DIY Less documentation Express Restify
- 8. Pattern 2: Configuration ✤ HAPI ✤ Express and Restify (maybe…)
- 11. Strengths andWeaknesses Pros Supported by Walmart labs. Less known but getting momentum Very granular control over request handling Detailed API reference with support for document generation Significantly more functionality for building web servers Pseudo prescriptive with configuration centric approach Caching, Authentication and input validation available Plugin based architecture for scaling Cons Good construction blocks but left to your own devices to figure out design patterns Binds you to specific modules and tool chains (catbox, joi, tv, boom, good, travelogue, yar) All endpoints need to be created manually Developers may end up creating their own non-optimized libraries Every end point needs to be tested Refactoring is painful, update everything everywhere
- 12. Pattern 3: Convention - ORM ✤ Model driven development ✤ Any Datasource ✤ Automatic Rest API Generation
- 13. Router using LoopBack DELETE /items/{id} GET /items GET /items/count GET /items/findOne GET /items/{id} GET /items/{id}/exists POST /items PUT /items PUT /items/{id}
- 16. Strengths andWeaknesses Pros Very quick RESTful API development Convention over configuration (extends express) Built in models ready to use (ORM) RPC support, Web and Mobile SDKs Data Connectors Fully configurable when needed Extensive documentation Commercial support and full time team working on project (Loopback) Mobile Services (Push, Geo, Storage, Sync, Offline, File, Device, User) - Loopback Authentication, validation and Authorization Cons Higher learning curve Opinionated
- 17. Pattern 4: Isomorphic JS & Full Stack ✤ Share Server Model with Client / Remoting ✤ Omni-Channel (Mobile, Web, IoT)
- 20. Pattern 5: MicroServices ✤ Decomposition ✤ Containment ✤ Flexibility ✤ Hyperscale
