Helper methods to get your data from Khan Academy

The problem

Khan Academy shut down their API, leaving you wondering how you could continue to keep your student data in sync between your LMS and Khan Academy.

This isn't...

This is not like the full Khan API. It is not meant for use in user facing environments.

This is..

If you need to get your data from Khan Academy using a backend service, this is for you.

Setup

This is run on Node. It uses axios to log into Khan Academy, and stores the cookies with tough-cookie and axios-cookiejar-support. Once authenticated, you should be able to get various data through the /api/internal/graphql endpoints.

install with

npm i --save khan-graphql

Usage

const { KhanApi } = require("khan-graphql")

const CREDS = {
  identifier: "your coach account",
  password: "your password",
}

const main = async () => {
  let kapi = new KhanApi()

  // always authenticate before retrieving data
  await kapi.authenticate(CREDS.identifier, CREDS.password)

  // now that we are authenticated, we can retrieve data. Let's get the coach data
  // with a helper method
  let data = await kapi
    .getCoach()
    .then((res) => res.data)
    .catch((err) => console.error(err))

  console.log({ data: JSON.stringify(data, null, 2) })

  // or inspect the network calls in Chrome dev tools while on Khan Academy to find
  // another endpoint, and use that. See CONTRIBUTING.md for more details

  let payload = {
    operationName: "getClassList",
    variables: {},
    query:
      "query getClassList {\n  coach {\n    id\n    joined\n    studentLists: coachedStudentLists {\n      name\n      id\n      cacheId\n      key\n      topics {\n        id\n        slug\n        title: translatedTitle\n        iconPath\n        domainSlug\n        learnableContentSummary {\n          countExercises\n          __typename\n        }\n        __typename\n      }\n      autoGenerated\n      countStudents\n      topicTitle\n      classroomDistrictInfo {\n        id\n        isNweaMapSynced\n        __typename\n      }\n      __typename\n    }\n    demoClassProgress {\n      completed\n      selectedTopics {\n        id\n        slug\n        __typename\n      }\n      __typename\n    }\n    __typename\n  }\n  user {\n    id\n    tosForFormalTeacherStatus\n    schoolAffiliation {\n      id\n      name\n      postalCode\n      location\n      __typename\n    }\n    affiliationCountryCode\n    __typename\n  }\n}\n",

  let customData = await kapi.getGraphQL("/getClassList", payload)

  console.log({ customData })

Contributing

I would gladly welcome any contributers to this project. There are many GraphQL endpoints on Khan Academy, with some great data. I would like to get some wrapper around those to make it easier to users to find their students' data.

Please see CONTRIBUTING.md for ideas on how you can help.
