[hsnhrn]

I am runnning the grpcwebproxy something like this:

I need to disable the log. which flag can i add to disable it?

Hi! Here are the supported options:

Lines 32 to 54 in 7dc9082

	flagBindAddr = pflag.String("server_bind_address", "0.0.0.0", "address to bind the server to")

	enableHealthEndpoint = pflag.Bool("enable_health_endpoint", false, "whether to enable health endpoint on the proxy. If enable_health_check_service is set to true the endpoint will serve the status got from backend, otherwise http.StatusOK(200) will be returned")

. There does not appear to be an option to disable logging. Would you be willing to contribute one?

I would love to contribute. A bit new to Golang thats why i will need a bit of help. Would you be able to help me in providing a little bit of documentation about it? Thanks a lot!

Lets explore actually if we can help each other in a different way. Have you tried just redirecting standard out to /dev/null when running the proxy?

grpcwebproxy --backend_addr=localhost:9090 --backend_tls_noverify > /dev/null
