Talking About How Javascript Based Node.Js Framework Complements SAP Modules? As requirement changes over time, modification needs to be done in the existing SAP HANA system. So, in order to meet the changing business requirements, changes also need to be done in the traditional runtime platform. Until now, HANA was mainly developed using an Extended Application service (XS). The XS engine is a lightweight application server inside HANA. Developers used to build multiple scripting applications using JavaScript to deliver Native SAP HANA web service and applications. As SAP always wanted HANA to support multiple languages, they need to re-architect the XS runtime. So, SAP HANA extended its application services in SPS 11 where the entire architecture is built upon previous strength while expanding its technical horizons. This allows SAP HANA SPS 11 to pick and choose which runtime and language it wants to support on HANA. The major changes one can find over here is; JavaScript runtime engine has been changed from Spider Monkey to Google V8 JavaScript or Node.js that delivers standard runtime, not as SAP branched or modified version.

So, the new JavaScript runtime in SP11 is planned to be based on Node.JS – One of the biggest changes faced by the developers.
Excellent Way to Connect SAP with Node.Js
Talking About How Javascript Based Node.Js Framework Complements SAP Modules? Unlike other web servers like Apache, it won’t spawn a process for every incoming connection instead, it will manage everything within a single process. And, this is achieved by using Node.js asynchronous I/O operations which won’t block engine execution and after calling an asynchronous function, it will instantly execute program code and a callback handler will be executed after completion of I/O process.
Being featured as the full-fledged HTTP server, it offers access to various network sockets, web sockets, file systems, and process management. Additionally, it also consists of various modules cluster, fs  (File System), events and request module that provides bindings for SAP Net WeaverRFC library where you can call various ABAP modules from node.js through SAP RFC protocol. Apart from this, there are multiple modules available for database connectivity.
Talking About How Javascript Based Node.Js Framework Complements SAP Modules? Node.js has quickly become one of the most effective standards for server-side JavaScript due to its robust non-blocking I/O programming that allows accessing, manage and reuse models in the best way. Though Node.js was hardly an SAP-specific technology, its excellent resources, and robust features make it compatible with SAP. The asynchronous I/O operations and swift result deliverance have made Node.JS development services, one of the best alternatives for the development of data-sensitive applications, Let’s watch how Node.js based JavaScript runtime engine in SAP improves server applications and boost company’s efficiency on a large-scale.
