not passing multiple custom fields

Seems to only pass the last custom field passed to customFields.

ie:

let parser = new Parser({
    customFields: {
      item: ['s:type','s:type'], 
      item: ['s:vendor','s:vendor']
      item: ['summary','summary'],
      //item: ['s:tag','s:tag'],
      //item: ['s:variant','s:variant', {keepArray: true}] //<---

    }
  });
   
  parser.parseURL('https://kith.com/collections/all/products.atom', function(err, feed) {
    //console.log(feed.extendedDescription);

if(!err){
    feed.items.forEach(function(entry) {
        //console.log(entry['s:type']);
        //console.log(entry['s:vendor']);
        console.log(entry.summary);
        //console.log(entry['s:tag']);
        //console.log(entry['s:variant']);
        //console.log(entry);
        
    });
    //console.log(feed.items[7]['s:type']);
    //console.log(feed.items[7]['s:vendor']);
    console.log(feed.items[7]['summary']);
    //console.log(feed.items[7]['s:tag']);
    //console.log(feed.items[5]['s:variant']['s:price'][0]['_']);
    //console.log(feed.items[5].summary);
   }else{
       console.log(err.message);
   };

Seems to only pass THE LAST item added to “customFields”. ‘s:vendor’ will show undefined untill “item: [‘summary’,‘summary’],” is commented out then it will work.

You syntax isn’t quite right:

let parser = new Parser({
    customFields: {
      item: [
        ['s:type','s:type'], 
        ['s:vendor','s:vendor']
        ['summary','summary'],
        ['s:tag','s:tag'],
        ['s:variant','s:variant', {keepArray: true}] //<---
    }
  });

And since you’re not trying to rename fields, it can be even simpler:

let parser = new Parser({
    customFields: {
      item: [
        's:type', 
        's:vendor',
        'summary',
        's:tag',
        ['s:variant','s:variant', {keepArray: true}],
      ]
    }
});

(Also note that your input above, which has multiple item fields, isn’t really a valid JS object - in JS, you can only specify one value per key).
