CAP plugins deconstructed - part 2 - service introspection in the REPL
| 1 min read
In this second of a three part series of blog posts, we look at how to explore service information in a running CAP server, digging into the entities, elements and annotations using introspection.
Background
This series of blog posts accompanies my session in the Developer Keynote at SAP TechEd Virtual this year. This is the second part that logically follows what I showed during the live session; now that we understand how the CDS plugin concept works, and have a skeleton plugin package, we need to work out what to do to inject behaviour into the service.
- Part 1 - understanding how the mechanism works
- Part 2 - service introspection in the REPL (this post)
- Part 3 - writing our own plugin
The examples in this series are based on CAP Node.js at release 8.3.0 (September 2024).
