Gatsby - build caching and image transformations

6

Just trying this out today (although I’m experiencing unexplained build failures). But I think the cache saving and restoration is working…?

Here’s my version of the script:

#!/usr/bin/env bash

# Ref: https://community.render.com/t/gatsby-build-caching-and-image-transformations/129/2

restore_render_cache() {
  local source_cache_dir="$1"
  if [[ -d "$XDG_CACHE_HOME/$source_cache_dir" ]]; then
    echo "CACHE HIT $source_cache_dir, rsyncing..."
    rsync -a "$XDG_CACHE_HOME/$source_cache_dir/" $source_cache_dir
  else
    echo "CACHE MISS $source_cache_dir"
  fi
}

save_render_cache() {
  local source_cache_dir="$1"
  echo "CACHE SAVE $source_cache_dir, rsyncing..."
  mkdir -p "$XDG_CACHE_HOME/$source_cache_dir"
  rsync -a $source_cache_dir/ "$XDG_CACHE_HOME/$source_cache_dir"
}

install_and_build_with_cache() {
  restore_render_cache "node_modules"
  yarn --frozen-lockfile --production
  save_render_cache "node_modules"

  restore_render_cache ".cache"
  restore_render_cache "public"
  export GATSBY_EXPERIMENTAL_PAGE_BUILD_ON_DATA_CHANGES=true
  yarn gatsby build
  save_render_cache ".cache"
  save_render_cache "public"
}
