I have just published an initial 0.1.0 version of a Node.js client for the Keycloak client registration API. You can check it out here: https://www.npmjs.com/package/keycloak-client-registration

It currently supports CRUD operations for Keycloak 'default' and 'openid-connect' provider endpoints. The documentation, such as it is, can be found here: http://bucharest-gold.github.io/keycloak-client-registration/. Please feel free to give it a spin. And if you do and have something to say about it, feedback is welcome.

The client requires Node.js 5.0 or higher, and is known to work with Keycloak versions 1.9.2 and 1.9.3.

If you find a bug, please provide as much detail as you can in a github issue: https://github.com/bucharest-gold/keycloak-client-registration/issues. Pull requests encouraged. :)

Cheers

Lance
