ChirpStack gRPC to REST API proxy

The ChirpStack gRPC to REST API proxy exposes the ChirpStack (v4) gRPC as REST API. While the gRPC API interface exposed by ChirpStack (v4) is recommended, in some use-cases a REST API can be more convenient. It could also help when migrating from ChirpStack v3 to v4 as previously this proxy was embedded inside the ChirpStack Application Server.

Usage

chirpstack-rest-api --server localhost:8080 --bind 0.0.0.0:8090 --insecure --cors "*"

• --server points to the ChirpStack gRPC endpoint. If ChirpStack is installed on the same machine and uses port 8080 (default), you can use the default value. You can also use the environment variable SERVER.
• --bind defines to which interface and port the REST API server will bind. In the above example (and default value), the REST API server will be exposed on port 8090. YOu can also use the environment variable BIND.
• --insecure indicates that the gRPC interface is not secured using a TLS certificate. You can also use the environment variable INSECURE (setting this to any value enables insecure mode, e.g. do not use INSECURE=false!).
• --cors defines the CORS policy by setting the AllowedOrigins Header. You can also use the environment variable CORS. --cors "*" allows all origins. Default is --cors 0.0.0.0 which disables CORS.
