GraphQL Tracer


Tracking performance for GraphQL in development is quite hard.

I'm using the Apollo Tracing format here. Unfortunately there isn't a good viewer for the information from there. It also doesn't include SQL/Cache information.


  • Viewer for tracing information
  • Store tracing information on disk, for future reference

<%= newsletter_links data.profiles %> were the most popular products last week.
