angular-cli/.circleci/config.yml

# Configuration file for https://circleci.com/gh/angular/angular-cli

# 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.
# http://yaml-online-parser.appspot.com/

# Variables

## IMPORTANT
# If you change the cache key prefix, also sync the restore_cache fallback to match.
# 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.
