I was working on some nodes to use with Salesforce but I stopped that work once I realized that developing forms for my nodes would take some time and could end up in spaghetti code if I used a single .html file to write everything I would need. So, I went on a journey to find a way to write node forms using Vue, and I think I reached a level where I'm happy with it. Therefore I can finally return to work on those Salesforce nodes. In the following link you can see the current implementation of these nodes. I built it with another guy I met online and then we made it public because people can help us improving them.
However, before I continue with the implementation, I would like to understand if there is anybody using Node-RED with Salesforce, and how you guys are using it
One thing I think node-red would be useful, besides querying data, is for demoing things like oauth/openid flows. So the first thing I'm planning is to add PKCE and authorization grant flows.
