Capture data sent to the Sidecar

You can run the Sidecar with SPOTLIGHT_CAPTURE=1 to write the captured data to a file. So for example if any Sentry SDK sends an envelope to the Sidecar, it will be written to a file in the current directory looking like this: application_x_sentry_envelope-1701167447043.txt.

All these files can be put into ./packages/overlay/_fixtures and used for testing. Also, they can be attached to Github issues to reproduce bugs.

Send sample data to Spotlight

If you run pnpm sample in ./packages/overlay it will send a sample event to the Sidecar and therefore to Spotlight. All .txt files that are contained in ./packages/overlay/_fixtures will be sent. This can be very handy when testing Spotlight locally.
