  • also photoswipe svg and gif assets are being written as a random SHA to the root of public/packs

• photoswipe not working properly on photography page
  • disabling splitChunks fixes it
• photoswipe image assets not being loaded (paths are wrong?)
• can we re-enable split chunks?
• double check all paths to assets are updated on all pages
• set up webpack-dev-server + HMR
• activeadmin
  • Webpacker is deprecated activeadmin/activeadmin#7376 (comment)
  • we can use this webpack config Webpacker is deprecated activeadmin/activeadmin#7376 (comment)
