How might we zonify loopback?

zonify-loopback.md

Here is a basic (truncated) callstack for a REST request to loopback.

• GET /users
• loopback.rest()
  • loopback.token()
  • Model.checkAccess()
  • sharedMethod.invoke(argsFromHttpCtx)
    • User.find()
      • connector.find()
        • driver.find()
  • sharedMethod.toResult(callbackArgs)
  • res.send(result)

Below is the important async calls during a loopback http request:

// LoopBack Zones
loopback.rest() // async (middleware)
loopback.token() // async (middleware)
Model.checkAccess() // async 
sharedMethod.invoke(argsFromHttpCtx) // async

// Juggler (Connector) Zones
driver.find(..., callback); // async

Proposed Zones

Request // done-ish (should set data.req and data.res)
  Access Control // loopback/lib/middleware/token.js 
    Remote Method Invocation // strong-remoting/lib/shared-method.js
      [Driver Invocation] // juggler/lib/dao.js ***

Proposed Invocation Context

zone.data.ctx = new Context(req, res, app, method);

Model.currentContext = function() {
  return zone.data.ctx;
}
