At Node-RED Con I spoke about the future roadmap of Node-RED and what we were planning for Node-RED 5.0.
I've now published the blog post version of the talk. Let us know what you think - and keep an eye out for the start of the Node-RED 5.0 beta releases this week!
I do hope that, as part of any code modernisation, robust in-line comments and more complete API documentation can be included? Both of these help lower the bar for other developers to get involved.
