I already wrote two blogs (one, two) about my open source development OData server for node.js, in short n-odata-server. Cause I personally use it during development and testing of my SAPUI5 / OpenUI5 applications it is not just a node.js topic but maybe also interesting for SAP developers in general. Read blog one for more details.
As the package gets more mature also thanks to a few contributors I started writing more documentation.
Last weekend I created the first tutorial in a series of those. This tutorial enables you to setup a node.js project with a simple data model and provide an OData API for it.
You only need about 30 minutes to create your first OData service that you then can use in your UI5 applications (read blog two) or wherever.
I plan to write more tutorials that illustrate more details about a useful integration into your UI5 development projects.
