Shopify alternative feed template (pagination)
In case you experience issues with products missing, you can use an alternative feed template. This utilizes Shopify’s pagination system to avoid their collection display limits. The template differences are:
We paginate the collection, meaning Shopify will automatically generate pages such as exampleshop.co.uk/pages/squeezely-product-feed?page=2 (as many pages as needed).
We list the next page link in the theme via the <nextpagelink> attribute. We then recursively retrieve each next page link until we reach the last page.
We only list the categories on the first page to avoid redundant data.
Template:
{%- layout none -%}<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">
<channel>
<title>{{shop.name | escape_once }} Squeezely Feed</title>
<link>{{shop.url}}</link>
