by Rafał Legiędź - If you're one of those developers who are tied to a .NET platform but are willing to use JavaScript whenever possible? Or maybe you develop server-side applications in JavaScript and you would like to call infrastructure code written in .NET? During this session you will get to know how to deal with above scenarios by using Edge.js module, which allows you to run Node.js and .NET code in one process on Windows, MacOS, and Linux.

Node.jsPlatform built on Chrome’s V8 JavaScript engine that provides an event-driven architecture and a non-blocking I/O API that optimizes an apllication’s throughput and scalability.

Node.js in practice
„[..] the only developer community that was built from day one around asynchronous, event-driven application logic as a core principle.”
~ Node.js is taking over the Enterprise
„On Black Friday the WalMart servers didn’t go over 1% CPU utilisation and the team did a deploy with 200,000,000 users online.”
~ Why Node.js is becoming the go-to technology in the enterprise

Node.js use cases
MILAN november 28th/29th, 2014 – Rafał Legiędź
.NETAdvantages over Node.js:

Edge.js„[..] provides an asynchronous, in-process mechanism for interoperability between Node.js and .NET”
…on Windows, Linux and Mac OS X

Edge.js – interop model
MILAN november 28th/29th, 2014 – Rafał Legiędź
Edge.js – possibilitiesEnables or simplifies application scenarios which are hard or impossible to achieve with Node.js alone:•implementing CPU-bound workloads in-process•simplifying access to Windows specific functionality•extending Node.js in .NET instead of native C
in any CLR language using inline code, separate files or assemblies.

What problem does it solve?
MILAN november 28th/29th, 2014 – Rafał Legiędź
Edge.js – code
MILAN november 28th/29th, 2014 – Rafał Legiędź
Installing Edge.js• >= Node.js 0.8.x• .NET Framework 4.5 or Mono 3.4.0

.NET that scripts Node.js in-process
MILAN november 28th/29th, 2014 – Rafał Legiędź
Tips• External class/assembly over inline code• Separate modules• Stay async• Benchmark• Node.js Tools for Visual Studio (Windows only)
MILAN november 28th/29th, 2014 – Rafał Legiędź
Alternatives• Stick with Node.js if possible• Process invocation (Node.js’s process api)• WebService (local/remote)• *MQ
