# Configuration file for https://circleci.com/gh/bazelbuild/rules_typescript

# 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.

## IMPORTANT
# If you change the `docker_image` version, also change the `cache_key` suffix
