FetchFrame

FetchFrame is an easy to use, resource based system for using Facebook's DataLoader library which makes it easier to handle per request permissions and caching in a more terse way.

npm install --save fetchframe

## Example

import { Frame, Schema } from "fetchframe"

// Create a Schema
let mySchema = new Schema({
    resources: {
      User: {
        dimensions: {
          id: {
            dimensionKey: (user_object) => user_object.id,
            retrieve: (query, context) => {

              if ( context.ip === "0.0.0.0") {
                return getAllUsersByIds(query)
              } else {
                return getSomeUsersByIds(query)
              }

            }
          }
        }
      }
    }
})

let firstFrame = new Frame(mySchema, {
  authenticationToken: "person1",
  ip: "192.168.1.1"
})

firstFrame.User.loadById(1)
  .then((user) => {
    // User is fetched and cached, with the correct permission
    // level from the datastore for the lifetime of the frame!
  })

The above is just a quick example of how the system works - read the Getting Started Guide to learn more!
