Hello Alessio, I am not an expert of NiFi UI, but tried to find where to customize to apply a default color.
Here is the Javascript function that creates new Processor instance by sending a REST request to NiFi Web API: https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-web-ui/src/main/webapp/js/nf/canvas/header/components/nf-ng-processor-component.js#L201 The processEntity object in the JS will be mapped to this DTO class in NiFi server: https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-client-dto/src/main/java/org/apache/nifi/web/api/dto/ProcessorDTO.java#L35 Current JS code doesn't specify any style, but if you add following style property in the object, I think you can get what you'd like to: 'component': { 'type': processorType, 'name': name, 'position': { 'x': pt.x, 'y': pt.y }, 'style': {background-color: "#853333"} } And you can embed color mapping to processorType, perhaps. Hope this helps, Koji On Mon, Feb 6, 2017 at 5:01 PM, Alessio Palma <[email protected]> wrote: > Hello all, > It's fact that each processor can be coloured; there is a way to set a custom > default color? > What we need is to add a map into nifi configuration so that when a processor > is moved into the workbench it already has its own colour. > > So the question is how much complex is add this feature to nifi and where I > should look to make the changes. > > Thanks in advance. > > AP > >
