# Ideally we'd only have to list the lockfile, and `yarn install`
# would take care of the rest. But that's not the case, because
# `yarn install` would still build packages, even if they'd already
# been built before. Yarn's message is:
# `YN0007: │ esbuild@npm:0.16.7 must be built because it never has been before or the last one failed`
# I couldn't figure out how to make it not build packages, so I
# added the `package.json` files to the cache key (so in a later step, we can entirely skip the install step).
#
# However, this means that if we add a new workspace under any of the
# existing workspaces, run this action, and then change the package.json
# of that new workspace, then the cache will be hit, and the new package.json
# will be ignored.

# This step is only needed if the job runs playwright tests. But we have
# to include it in all jobs. The reason is, both `yarn install` and `yarn run playwright install`
# modify the `~/.cache/ms-playwright` folder. If we don't include this step in all jobs,
# then the cache will change in some jobs and not in others, which would make the cache useless.
