Modern Web APIs with Node.js & TypeScript

Full-Stack-Development! Modern frontends are using Single-Page Applications like Angular or React communicating with some light-weight Web APIs in the background. Thanks to Node.js we can speak one language in both worlds: JavaScript … or even TypeScript! Within this session we want to take a look at building modern and light-weight Web APIs based on Node.js with TypeScript and connect to a database using an ORM called SequelizeJS. A few lines of code are needed to create a “next generation” Web API.

   Web API Architecture
   • Lightweight service-based architecture
   • Functional services with dedicated interface
   • Aggregates other services
   like database or file system
   • (JSON-based) HTTPS Web APIs
   • Application push services via WebSocket
   • Socket.io
   • SignalR
   HTTP HTTPS WebSocket
   Service A Service B Service C
   Web APIs
   (ASP.NET, Node.js, …)
   AuthN & AuthZ
   Client

5. • Server-side JavaScript powered by Chrome’s V8 JavaScript engine
   • Asynchronous, event-driven I/O API
   • Cross-platform: Linux, macOS, Windows
   • ECMAScript 6 & 7 features
   • Additional tooling power via TypeScript
   • Enterprise proven: Netflix, Paypal, Groupon, Walmart
