# Note: YAML anchors allow an object to be re-used, reducing duplication.
# The ampersand declares an alias for an object, then later the `<<: *name`
# syntax dereferences it.
# See http://blog.daemonl.com/2016/02/yaml.html
# To validate changes, use an online parser, eg.

# Note that the browser docker image comes with Chrome and Firefox preinstalled. This is just
# needed for jobs that run tests without Bazel. Bazel runs tests with browsers that will be
# fetched by the Webtesting rules. Therefore for jobs that run tests with Bazel, we don't need a
# docker image with browsers pre-installed.
# **NOTE 1**: If you change the version of the `*-browsers` docker image, make sure the
#             `CI_CHROMEDRIVER_VERSION_ARG` env var (in `.circleci/env.sh`) points to a ChromeDriver
#             version that is compatible with the Chrome version in the image.
# **NOTE 2**: If you change the version of the docker images, also change the `cache_key` suffix.

# We don't want to include the current branch name in the cache key because that would prevent
# PRs from being able to restore the cache since the branch names are always different for PRs.
# The cache key should only consist of dynamic values that change whenever something in the
# cache changes. For example:
# 1) yarn lock file changes --> cached "node_modules" are different.
# 2) bazel repository definitions change --> cached bazel repositories are different.
# **NOTE 1 **: If you change the cache key prefix, also sync the restore_cache fallback to match.
# **NOTE 2 **: Keep the static part of the cache key as prefix to enable correct fallbacks.
# See https://circleci.com/docs/2.0/caching/#restoring-cache for how prefixes work in CircleCI.
