A BPMN workflow engine using firebase triggers and functions?

[Traco]

Hi 

There are some BPMN based workflow engine written with javascript. Most of them depends on traditional database and message queue to keep/transit status and extension of task is not straight-forward.

On firebase environment, a high scalable workflow engine would be good to have and make the serverless setup more useful. Is there any such engines (unlike dataflow) or anybody are interested to build one?

Best,

Sorry whether I understand your idea. But we used to achieve this workflow using those cloud functions, triggers, event listeners etc. It's not available as a framework to use it but we can build based on needs.

I am referring to products like Activiti, Camuda and light weight javascript implementation like bpmn-engine https://www.npmjs.com/package/bpmn-engine.

Give an example of Activiti, designer could define the workflow with standard BPMN models, triggered by email/timer/etc, and transit to different tasks such as user input form, scripts and external functions. However, existing BPMN engines scalability would be limited by backend database and trigger types may not include firebase triggers, and function extension won't be as convenient as firebase deployment.

With all firebase features, I can see the potential to build a more scalable and extensible while lighter services than what above products offer.
