How can we create a user with Firebase Auth in node.js?

I'm trying to create user account using Firebase auth in nodejs. It doesn't work and I don't know why. Here's the code and the error generated by nodejs:

var config = {.......}; // i can't share the config

var app = firebase.initializeApp(config);

var db = app.database();
var auth = app.auth();

auth.createUserWithUsernameAndPassword("anemail@gmail.com", "@NewPassWord").then(
    function(user){ console.log(user);},
    function(error){ console.error(error);}
);

Error generate by NodeJS:

TypeError: Object [object Object] has no method 'createUserWithUsernameAndPassword'
    at Object.<anonymous> (/home/antonio/Projects/firebase/app.js:20:6)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)

NOTE: This isn't an answer but is extending this answer by @Gregg above.

I too was struggling to create users using an service account with Firebase + node + express.

For anyone else interested:

In the root app.js I have:

var admin = require("firebase-admin");
var serviceAccount = require("./key.json");

admin.initializeApp({
   credential: admin.credential.cert(serviceAccount),
   databaseURL: "https://<app-name>.firebaseio.com"
});

and in the auth.js route I have (as per @Gregg):

const firebase = require('firebase-admin');

firebase.auth().defaultAuth.createUser({
  email: req.body.email,
  password: req.body.password,
  displayName: req.body.username,
})

I know this is only a slight extension to the earlier answer however the docs seem to be very unclear, and I've noticed a large number of people that have the same or similar problem.

As of May 2017, this is what we are using successfully.

  // Create the authenticated user
  admin.auth().createUser({
    email: email,
    password: password,
    displayName: `${firstName} ${lastName}`,
  })

I finally got it working in Node.js. Is your app an instance of firebase-admin by any chance, as opposed to firebase?

In my express app I initialise firebase in the main app.js like so (pretty standard fare):

var firebase = require("firebase");

firebase.initializeApp
({
  apiKey: "xxx",
  authDomain: "xxx",
  databaseURL: "xxx",
  storageBucket: "xxx",
  messagingSenderId: "xxx"
});

Then in the route responsible for creating users I do this:

var firebase = require("firebase");

router.post('/register', function(req, res, next)
{
  var email = req.body.email;
  var password = req.body.password;

  firebase.auth().createUserWithEmailAndPassword
  (
    email,
    password
  )
  .then(function(userRecord)
  {
    res.location('/user/' + userRecord.uid);
    res.status(201).end();
  })
  .catch(function(error)
  {
    res.write
    ({
      code: error.code
    });
    res.status(401).end();
  });
});

Cyrus' response is correct.

However, please note that as of Nov 2016 the way to do this is the following:

firebaseAdmin.auth().createUser({
    email: "user@example.com",
    password: "secretPassword"
  })
  .then(function(userRecord) {
    // A UserRecord representation of the newly created user is returned
    console.log("Successfully created new user:", userRecord.uid);
  })
  .catch(function(error) {
    console.log("Error creating new user:", error);
  });

See a more complete guide in the official documentation.

well, I don't think that the method "createUserWithUsernameAndPassword" works,

Use this instead createUserWithEmailAndPassword

you used username when firebase use email
