I've been working on a detailed query tracer which produces artifacts for Perfetto (https://perfetto.dev). In this PR I'm going to:
GraphQL::Dashboard, which is a Rails enginePerfettoTraceso that traces can be saved for later (Redis and ActiveRecord)Why a Rails Engine? I've seen it done nicely, eg https://github.com/bensheldon/good_job, https://github.com/mbajur/inner_performance. I have rolled my own in
GraphQL::Pro::Dashboardfor a long time but I'm not sure it's worth it. I think everyone uses Rails, and an Engine will bring a lot of convenience in development, robustness in production, lots of configuration options. If you're not using Rails, I think you could spin up a sidecar app just for running the dashboard if you need to.I plan to replace
GraphQL::Pro::Dashboardwith this one (rolling its features into this one).TODO:
