How can the underlying protocols of services be abstracted into the language itself? Looking at it here with a transpiled JS language, but a library might work as well. Best past attempt is a JS library, https://github.com/pfraze/servware, which is convenient, but still exposes the HTTP. This removes protocol details (headers, status codes) enti…

// defining services

var usersCollection = [];

service Main {
  link collection = Users;
  meta rel = 'service';
  meta id = 'main';
}
local.hostChannel.bind(Main);

service Users {
  link up = Main;
  link item = User;
  meta rel = 'collection stdrel.com/crud-coll';
  meta title = 'Users Collection';
  meta id = 'users';

  method GET/json(online)
  {
    if (online) {
      return usersCollection.filter(isOnline);
    }
    return usersCollection;
  }
  method GET/html()
  {
    return '<h1>Hello, World</h1>';
  }
  method POST/json()
  {
    // :TODO: how is stream received?
    usersCollection.push(newuser);

// defining agents

agent Coll(id) from Service [{
  rel = 'stdrel.com/crud-coll';
  id = id;
}]
agent Item(id) from Coll [{
  rel = 'stdrel.com/crud-item';
  id = id;

agent Item(coll, id) from Service [
  { rel = 'stdrel.com/crud-coll'; id = coll; },
  { rel = 'stdrel.com/crud-item'; id = id; }
]
agent User(id) from Service [
  { rel = 'stdrel.com/crud-coll'; id = 'users'; },
  { rel = 'stdrel.com/crud-item'; id = id; }
]

// using agents, streams

var myHost = Service('http://myhost.com');
var users = myHost.Coll('users');
var bob = myHost.User('bob');

var bobData = yield bob.GET/json();
var json = yield users.GET(); // will default to json because json is first in the service definition
var html = yield users.GET/html();
var json = yield users.GET({online: true});

var patch = stream(bob.PATCH/json);
patch().then(onSuccess, onFailure);
patch.end(bobData);
