Really cool! Is there a way to export a data representation of your graph, like in json or something? Would there be a standard for that, like some control flow

Node-red? Great visual workflow system based on MQTT, but you can also program UIs in it (node-red-dashboard), cluster process stuff with plugins, and even program this stuff on mobile (https://github.com/alexisread/noreml https://github.com/alexisread/noreml). It can import/export json representations of the diagrams/code. I've found mermaid (and vue-mermaid) useful for just the workflow representation as the diagrams are compact, though the lines don't curve like in other libraries

Use BPM/BPMN? (Business process modelling) Not answering you question directly, but it’s a way of doing something similar. A whole set of enterprise tools do things like this, and I’ve worked a bit with bpm workflow engines that kind of does this in a standardized way. > BPMN models are expressed by simple diagrams constructed from a limited set of graphical elements. For both business users and developers, they simplify understanding of business activities' flow and process. BPMN's four basic element categories are: - Flow objects: Events, activities, gateways - Connecting objects: Sequence flow, message flow, association - Swim lanes: Pool, lane - Artifacts: Data object, group, annotation https://en.wikipedia.org/wiki/Business_Process_Model_and_Notation https://en.wikipedia.org/wiki/Business_Process_Model_and_Not... You can use web tools to draw processes and, execute them on a compliant engine: https://demo.bpmn.io/ https://demo.bpmn.io/ Camunda comes to mind, as an open source alternative, but if nodejs is your thing there a a couple of BPM engines in the works, eg: https://github.com/paed01/bpmn-engine https://github.com/paed01/bpmn-engine As with anything graphical based - if it doesn't fit the purpose exactly, it will become a pain in the end.

  I remember I had to do one project at my university. I hated it. I still wonder if there is a successful product out there which I made through bpm. I doubt it.

    Same here, actually... well, not uni, but as a consultant and employee. It’s “ok” if you own the whole lot, but I have yet to see a hand-over in an enterprise setting work out well, and bring speed and agility. In many ways, for an enterprise, json and web api’s is a good enough abstraction to work with the machines. Tangential to this - Netflix made Conductor as a kind of in-house workflow engine, and uber built Cadence, if you want more codified control. Wheels keep getting re-invented! :)

Looks like editor.toJSON() exports the current graph. I tried it in the dev consolve, on this page: https://rete.js.org/#/components https://rete.js.org/#/components The exported object has properties id (string) and nodes (array). Each node is shaped like: { "id": 1, "data": { "name": "rete", "importance": 1 }, "inputs": { "pkg": { "connections": [ { "node": 2, "output": "pkg", "data": { "pins": [] } } ] } }, "outputs": { "pkg": { "connections": [ { "node": 3, "input": "pkg", "data": { "pins": [ { "x": 306.4013957327592, "y": -1661.933328730452 } ] } } ] } }, "position": [ -509.99078981156725, -241.02053426307492 ], "name": "Package" }
