git clone https://github.com/HarperFast/template-early-hints
cd template-early-hints
harper-agent
party

• Handle large-scale redirect needs:
  https://github.com/HarperFast/template-redirector
  Sync with Marianne, what are the steps for getting this in production for someone? Complete steps, and then how can I make that easy with npm create harper

• Full-Page Caching Component: ready-to-use caching logic
  https://github.com/HarperFast/full-page-caching
  Say you have a next app... hosted in one location... you pick the full page caching template, it asks you for a existing URL... it sets up an example of caching it...

• E-Commerce Template: pre-rendered storefront foundation
  https://github.com/HarperFast/harper-ecommerce-template

  Let this be picked and added to any of the other existing templates, which will config and install the right dependency

  https://github.com/HarperFast/image-optimizer

• Deploying a static prerendering system built on Harper and a headless rendering service
