# Many build steps have their own caches, so each job has its own cache to improve subsequent build times.
# Build tools are configured to cache to node_modules/.cache, so they are cached independently of node_modules.
# Caches are saved every run (by keying on github.run_id), and the most recent available cache is loaded.
# See https://jongleberry.medium.com/speed-up-your-ci-and-dx-with-node-modules-cache-ac8df82b7bb0.
