Spring Flo is a JavaScript library that offers a basic embeddable HTML5 visual builder for pipelines and simple graphs. This library is used as the basis of the stream builder in Spring Cloud Data Flow.

Here is a youtube video of Spring Flo in action.

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

Spring Flo is built using Grunt. Grunt commands can be run directly or indirectly through maven. Simplest way to build is via mvn clean package to build the project and run the tests. Build results are produced under the dist folder. Contents of the folder are

• spring-flo.js that contains all JS code from various JS dev modules (produced by development build)

• spring-flo.min.js a minified version of flo.js (produced by production build)

• spring-flo.css concatenated CSS file for Flo Editor

• spring-flo.min.css minified version of the CSS above

If you have any questions, issues, feedback or feature request please raise an issue.

A small self contained sample usage of Spring Flo is now available in the samples sub folder. It includes a README that describes running it and where you might want to customize it. The Spring Cloud Data Flow UI at github shows a larger scale usage of Spring Flo.
