RSS Feed & Join

Question

I can't join JSON object.
Debug console always empty.
I want to get like this.

[
  {
    "title": "aaa",
     "description": "...",
     "link": "http://..."
  },
  {
    "title": "bbb",
     "description": "...",
     "link": "http://..."
  },
  {
    "title": "ccc",
     "description": "...",
     "link": "http://..."
  },
]

Environment

  • Node-RED 1.0.6
  • node-red-node-feedparser 0.1.15
