Hello, guys!
Not so long ago, I had written a new mix package : phx_json_rpc.
It allows you to describe your services as JSON-schema and serves http-requests in batches with async order.
In some cases it can be very useful.
If you would like to try something different except REST or GraphQL, I hope it can help you.
The repo contains guide, covering usage with phoenix.
Feel free to try it out! Any feeedback is appreciated.
