How To Use

Refer to the wiki for more information on how to embed it in an application.

Please ensure that at a minimum Node.js, npm and the Angular CLI are available on your system. In order to execute the build simply do:

$ git clone
$ npm install
$ npm run build

Build results are produced under the dist folder.

A small self contained sample usage of Spring Flo is available in the demo sub folder. Execute npm start to run the sample. The Spring Cloud Data Flow UI at github shows a larger scale usage of Spring Flo.

Spring Flo is Open Source software released under the Apache 2.0 license.
