    khan

    Khan academy API wrapper

    Installation

    npm install khan

    Usage

    This package exports a single, autocurried function. This function takes up to 4 parameters:

    • consumerKey - provided by Khan when you register your application
    • consumerSecret - provided by Khan when you register your application
    • tokenSecret (optional) - obtained when the user authorizes your application
    • accessToken (optional) - obtained when the user authorizes your application

    All of these are optional. If you don't call the function, it is simply a map of unauthenticated requests you may make. Because it is autocurried, you may continue calling it indefinitely with more parameters. E.g. khan(consumerKey)(consumerSecret) is equivalent to khan(consumerKey, consumerSecret), so you can nicely make partially applied versions of the wrapper for different contexts. This pattern in particular is useful:

    var khan = require('khan')(consumerKey, consumerSecret)
     
    function getExercises (user, exerciseName) {
      var userKhan = khan(user.khan.oauth_token_secret, user.khan.oauth_token)
      return userKhan.userExercise(exerciseName)
    }

    Methods

    These methods are properties on khan (or any curried instance of khan). Unless otherwise specified, they all return promises:

    • request(apiPath)

      • this is a special method that allows you to request any arbitrary path of the khan api. If you call request(/somepath), it will send a (signed if authenticated) request to https://www.khanacademy.org/api/v1/api/v1/somepath.

    requestToken

    Params:

    • redirectUri (optional) - Where the user should get redirected after they authorize

    Example - Getting a request token

    var khan = require('khan')(consumerKey, consumerSecret)
     
    khan
      .requestToken()
      .then(function (res) {
        // res = {oauth_token, oauth_token_secret}
        // where 'oauth_token' is your request token
        // you now need to have the user authorize it
        // from their browser
      })

    accessToken

    Retrieve an access token.

    Params:

    • requestToken - The request token you received in the previous request
    • verifier - The oauth verifier returned by the authorize step
    • tokenSecret - the token secret you received in te previous request

    Example - Getting an access token

    var khan = require('khan')(consumerKey, consumerSecret)
    
    khan
      .accessToken(requestToken, verifier, tokenSecret)
      .then(function (res) {
        // res = {oauth_token, oauth_token_secret}
        // where, in this case, oauth_token is your access token
        // which you may now use to make authenticated requests
      })
    

    exercise

    Retrieve public data about a particular exercise.

    Params:

    • exerciseName - Exercise name

    Example - Retrieving data about an exercise

    This is a completely public request, so it doesn't require any auth parameters:

    var khan = require('khan')
     
    function getExercise(name) {
      return khan.exercise(name)
    }

    userExercise

    Retrieve a user's state on a particular exercise.

    Params:

    • exerciseName - Exercise name
    • userId (optional) - User id. If not passed, retrieves data for the currently authenticated user.

    Example - Getting exercise data for a particular user

    var khan = require('khan')(consumerKey, consumerSecret)
     
    function getUserExercise (user, exerciseName) {
      khan(user.oauth_token, user.oauth_token_secret)
        .getUserExercise(exerciseName)
        .then(function (exercise) {
          // Do some stuff
        })
    }
