Depending on how you look at it, my largest RapidWeaver-based site has either 70 pages, or 36,887 pages.
The site is Promo.zone ( https://promo.zone ), and it’s a search engine for promotional products. Each product has its own dynamically generated page. The 70 pages that make up the RapidWeaver project are used to create the 36,000+ product pages - and they do so “on-demand” so to speak.
I developed the site using the Foundry framework, as well as a custom microframework that I developed, and a handful of custom stacks. The product information is stored in a MySQL database. The site and database are hosted using Amazon Web Services. More information about the technologies that I used can be found in the site’s FAQ ( https://promo.zone/faq/ ).
Promo.zone is the largest, most complex, and most successful site that I’ve developed with RapidWeaver. I don’t sell anything through the site, but it does generate a lot of traffic. As a result, it also generates a lot of inquiries from companies in the promotional products industry, who are interested in the technical services that I provide.
