Download link for Client Side Catalog Template? to load 10k data

Hello,

We currently have 10k data that we're importing from Ventrian Property-Agent module into open content.
Copying it into RawData is fine, but when it load the page, it throw error "Too much data to deserialize. Please use a client side template to circumvent that."

Update the limit of jsonSerialization maxJsonLength didn't solve it, so we're thinking to implement Client Side load, but no sample template we can find for reference.

But I see that this page is implement Client side rendering with 10k data:
http://www.openextensions.net/opencontent-demos/client-side-catalog

Wonder where we can grab the template for this sample page?
