I found an excellent article on this very topic and decided to extend this a bit further with a client in NodeJS as well. Make sure you run the (Rust) server first.
We will need to use
Tonic
Tonic is a super lightweight gRPC implementation with batteries (prost, hyper, and protobuf) included to build both gRPC servers and clients. The server and client can leverage HTTP/2 and code generation to generate the necessary code for individual services from standard protocol buffer specifications (.proto).
This trivial example is still a private repository, but I will clean it up when time permits and share a link here - TBD.
Use the following to interact with the node client:
-> % node client.js --vote 0 --url foo.com
Resp: { confirmation: 'Happy to confirm that you upvoted for foo.com' }
-> % node client.js --vote 1 --url foo.com
Resp: { confirmation: 'Confirmation that you downvoted for foo.com' }I can interact with the server using the Rust client as well
