# This cache is used by {GraphQL::Language::Parser.parse_file} when it's enabled.
#
# With Rails, parser caching may enabled by setting `config.graphql.parser_cache = true` in your Rails application.
#
# The cache may be manually built by assigning `GraphQL::Language::Parser.cache = GraphQL::Language::Cache.new("some_dir")`.
# This will create a directory (`tmp/cache/graphql` by default) that stores a cache of parsed files.
#
# Much like [bootsnap](https://github.com/Shopify/bootsnap), the parser cache needs to be cleaned up manually.
# You will need to clear the cache directory for each new deployment of your application.
# Also note that the parser cache will grow as your schema is loaded, so the cache directory must be writable.
#
# @see GraphQL::Railtie for simple Rails integration
