Question

On my node.js server I have some JSON that I need to convert to an RSS feed. What is the best way to do this? After doing the conversion it will need to output/overwrite an RSS file.

Answer 1

consider using https://github.com/dylang/node-rss

example:

test.json:

{
  "title": "foo",
  "description": "bar",
  "author": "hello"
}

test.js:

var fs = require('fs')
  , RSS = require('rss');

fs.readFile('test.json', function(err, data) {
  if (!err) {
    feed = new RSS(JSON.parse(data));
    fs.writeFile('feed.xml', feed.xml());
  }
});

run node test.js will generate the feed.xml:

<?xml version="1.0" encoding="UTF-8"?>
<rss xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:atom="http://www.w3.org/2005/Atom" version="2.0">
