Expand description
Apollo tracing extension for performance tracing
Apollo Tracing works by including data in the extensions field of the
GraphQL response, which is reserved by the GraphQL spec for extra
information that a server wants to return. That way, you have access to
performance traces alongside the data returned by your query. It’s already
supported by Apollo Engine
, and we’re excited to see what other kinds of
integrations people can build on top of this format.
