1. JS Monthly, November 2016 COPE with Node.js microservices Eduardo Bouças eduardoboucas.com @eduardoboucas London
2. Part I — Discovery
4. Content Management System
5. Content Digital asset Management System
6. Content Digital asset User Management System
7. Content Digital asset User Layout Management System
9. Traditional (monolithic) CMS Core Database Admin UI Templates
10. Problem #1 Long-term commitment to tech stack and CMS components/features
11. Problem #2 How to integrate with external systems on different tech stacks?
12. Part II — Headless
13. Headless CMS Core Database Admin UI Templates Web server Templates Native app API
14. • Separation of concerns: content and layout are decoupled • Any front-end can be plugged in — RESTful + everyone speaks JSON • A single editing interface can be used to publish to multiple devices Benefits
15. • Separates data from design • Reduces editorial overhead • Content re-usable and future-proof Create Once, Publish Everywhere COPE
17. Problem #1 Web CMS still pivot of entire system.
18. Problem #2 Database, core and API still tightly coupled together. What happens if the publishing interface needs to change?
19. Problem #3 COPE as an afterthought.
21. • Data architecture and business logic agnostic of tech stack • Features as modular, interchangeable components • Universal language • Scalable on a micro-level A wish list
22. «An approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API.» Microservices Martin Fowler
23. COPE by design API-first approach Modular components Built in Node.js Scalable Free and open source
24. API A high-performance RESTful API layer designed in support of API-first development and the principles of COPE. Publish A writer’s window to the world of content creation. Flexible interfaces designed to optimise editorial workflow. CDN A just-in-time asset manipulation and delivery layer designed as a modern, global content distribution solution. Web A schemaless templating layer that can operate as a standalone platform or with API as a full stack web application. The suite

27. • > 100 million users a month • Editorial teams of up to 400 people • 250,000+ peak concurrent users Some numbers
28. • Scalability • Developer liberation • Fast to market Key benefits

30. • Holds data architecture and business logic in JSON schema • Content stored as documents, grouped in collections • Fully REST (data and metadata) • Customisable with hooks DADI API
