How to integrate Product Reviews in an Episerver website
In this post, I will go over how I implemented integration between my Episerver website with ProductReview.com.au
There were three things involved in the development:
- Custom Plugin – This really is just a settings page that allows authors to add multiple endpoints/APIs from Product Reviews (i.e. you have multiple products up for reviews)
- Scheduled job that grabs the latest reviews for all your products and stores the response internally
- New block that allows authors to render the outcome of the product review
Two reasons why we opted for the scheduled job approach instead of server-side/AJAX call on render of page are:
- Performance – we don’t have to make an extra server-side call to Product Reviews every time a webpage on your site is rendered since the latest results are already stored internally
- SEO – Google can’t index these reviews if the reviews are loaded through an AJAX call. The reviews have to be part of the first render of the page.
Plugin – Import External Data
public class ExternalData : BaseDbEntity
{
public string Source { get; set; }
public string Endpoint { get; set; }
public int DataType { get; set; }
public string Response { get; set; }
public DateTime? ImportDate { get; set; }
}public class ExternalDataMap : BaseEntityTypeConfiguration
{
public ExternalDataMap()
{
ToTable("Module_ExternalData");
Property(e => e.Response).IsMaxLength();
}
} @model List<Fusion.Cms.Core.Components.DataImportHandler.Models.ExternalData>
