Simple trick to avoid decoding / encoding if one use Bucklesript on client and server

Interop.re

type t = {
    test: string,
    value: int
};


external consume_client: string => t = "JSON.parse" [@@bs.val];

external prepare_server: t => string = "JSON.stringify" [@@bs.val];

let test = { test: "Hello", value: 42};
Js.log "test:";
Js.log test;

let sent = prepare_server test;

let consumed = consume_client sent;

Js.log "consumed:";
Js.log consumed;
