gRPC Locations

Example implementation of a location reporting system based on gRPC and protocol buffers. Clients send diff based location data in binary streams. The server lists them and marks the stalled ones.

Part of an interview proces with Balena (2020).

demo-grpc-locations's Issues

Upgrade to @carnesen/[email protected]

Hi @TobiaszCudnik . Thank you so much for being an early adopter of @carnesen/cli. We just put out a huge new release, v0.5.0. On the plus side, the library is now thoroughly documented online and in the source code, and we made an online examples page too. Unfortunately for this project though, 0.5.0 has a lot of breaking changes in the API versus your version 0.3.0. We really appreciate you taking a chance on our relatively-obscure library and would like to reward that by offering our assistance in performing the 0.3.0--> 0.5.0 upgrade. Just say the word and we'll submit a pull request for it. It would be a good chance to learn about grpc too! If we don't hear from you on this issue, we'll close it in a few weeks.

Cheers,
Chris Arnesen for the @carnesen/cli team
