ReScript RPC like?

I used rescript-hono/src/Hono.res at main · AlexMouton/rescript-hono · GitHub

(and in my project the additional

type middleware

@module("hono/cors")
external cors: unit => middleware = "cors"

@send
external use: (Hono.t<'t>, middleware) => unit = "use"

// To use 
app->use(cors())

)
