You can also see how simple it is to call the HANA DB and respond with the results. This file is firstly going to act as our web server for our web site, and secondly provide the data from our HANA server to the web page, pushing the data via web sockets.īelow is the app.js code, here you can see how we process each request based on the type and subsequently respond with the requested data. Next we develop the app.js file which is the brains of our operation. tags is important for updating the data being returned from the server ->

Once you have your page rendering the way you want, we can move on. Support for Apple's compression library ZLIB and XZ implementations This ZIP file deployment uses the same Kudu service that powers continuous integration-based deployments But the minute you went String/Buffer -> Compress -> Decompress -> String your data would be wrong if it had any UTF-8 encoded characters js: ExpressJS - Express is a flexible Node. No need to work with Node or any server for that matter. This aspect of node development is strictly “traditional” web based development. I was sure to “id” all of my elements on this page as we will be updating these values from our node.js backend. From a coding perspective I started out developing the Single paged “index.html” file, doing my best to stick with my mockup which I previously created. In this case I decided to use Twitter Bootstrap to help with some of the layout/formatting of the page as well as some mundane tasks like Modal popups. In our case, we will add a small chart in the center, giving us a basic visual representation of the numbers being displayed: I liked the simplicity, clean layout with focus on the numbers at the bottom. Once you have the dependencies installed we can start creating our app.įor me, I always start mocking up in my favorite Image IDE (Photoshop), I used this image as inspiration for my app.

Installing these packages is as simple as running “npm install hdb”.
We will also use a couple of helpful dependencies from the node community including Socket.io, Express and obviously hdb. Node.js installed (this does not need to be on the HANA box but same network with access to the HANA port – normally 30015). The dashboard is designed to be shown on a large format monitor in a Ops or IT center and can also very easily be modified to show any KPI’s relevant to your business or needs. The app gets streaming data from our HANA backend displaying this in a friendly, simple dashboard. This app, similar to another app I developed called Metric ² (which you can read about here), it is a web based widget showing some friendly KPI’s on the performance of your HANA Instance.

I encourage you to download a few of these components, and also the example out. The blog is intended to cover a small app developed in Node.js and shows the development process behind it, taking it from conception through to reality. This blog is not necessarily an introduction to Node.js development as there are some nice tutorials and examples out there from Tobias Hoffman and Alessandro Spadoni. I thought it would be good share the small project I developed using Node.js and this new client with the community in the hopes that others will share their experiences with the technology. The blog mentioned that Holger Koser had created a HANA DB Client for Node making life extremely easy to connect to HANA directly from Node. In the past, while developing HANA/Node apps, I resorted to creating a XSJS App which really just acted as a middleware layer to push and pull data from my HANA DB, until recently I noticed a great blog post from Ingo Sauerzapf which piqued my interest. ImageCompressor.A couple months ago I ran into a similar problem to Jon-Paul Boyd (HANA Forum Post) in which I wanted to use XS Engine for websocket/persistant connections to my HANA Instance, but due to the support not being included in SPS6, I decided to look elsewhere, and ended up using Node.js to fulfill this requirement.
