Support for production & profiling React builds

[dinkinflickaa]

I am trying to run react-render-tracker against a react profiling build but seeing this error in the console

dispatcher-trap.ts:292 
       Uncaught (in promise) TypeError: renderer.getCurrentFiber is not a function
    at Object.set [as current] (dispatcher-trap.ts:292:41)

Are there any plans to make the tracker compatible with the profiling build?

@dinkinflickaa Production and profiling builds provide limited API to React's internals. So, some data can't be captured for such builds. I have plans to support such builds with limited functionality. However, there is no ETA at the moment, since I focused on other features for now.

It also surprises me that you are getting an exception instead of a warning: "[react-render-tracker] Unsupported React renderer, only bundle type 1 (development) is supported but 0 (production) is found". What versions of React Render Tracker and React are you using?

Thanks for your response @lahmatiy. I made some changes locally to run the tracker against a profiling build, The stacktrace is probably the side effect of that.

I found that the new check and warning was not published at the moment of writing my comment. So now you should see a warning in RRT about an unsupported build.

Time to time, I get requests to support React build type other than development (i.e. production & profiling). Technically, it's possible but with a drawback that RRT will capture less data in this case, e.g. no owner-based hierarchy of components and less precision for a render/update cause detection. However, in some cases it might be not important at all. So I going to add such a support, with a reduction in data details due to a build type restrictions.

Just released 0.7.1 with basic support for production & profiling React builds.
Due to lack of API provided by production & profiling builds at the moment, some data is not capturing for these builds:

• No owner for components, so only parent-child hierarchy in the components tree is supported. It also prevents detection of triggers for an update in most cases
• No info about used hooks, including used contexts on functional components, memo hooks recomputation etc.
• Some updates might be missed in the event log
