Firebase - TypeError: admin.auth(...).createUserWithEmailAndPassword is not a function

Question

I am trying to create a user in firebase database using cloud functions. This is my code :

exports.AddUser = functions.https.onRequest(function(req, res){

    if(req.method == 'GET'){
        email = req.query.email;
        password = req.query.password;
        name = req.query.name;

        admin.auth().createUserWithEmailAndPassword(email, password).then(function(user){
            user.sendEmailVerification().then(function(){
                res.send("verification email sent.");
            }).catch(function(){
                res.end(user)
            })
        })
        .catch(function(error) {
            // Handle Errors here.
            var errorCode = error.code;
            var errorMessage = error.message;
            console.log(errorMessage);
            res.send(errorMessage);
        });

    }else{
        email = req.body.email;
        password = req.body.password;
        name = req.body.name;

        admin.auth().createUserWithEmailAndPassword(email, password).then(function(user){
            user.sendEmailVerification().then(function(){
                res.send("verification email sent.");
            }).catch(function(error){
                res.end(user)
            });
        })
        .catch(function(error) {
            // Handle Errors here.
            var errorCode = error.code;
            var errorMessage = error.message;
            console.log(errorMessage);
            res.send(errorMessage);
        });

    }

});

This is my package.json:

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "serve": "firebase serve --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "dependencies": {
    "firebase-admin": "~5.12.0",
    "firebase-functions": "^1.0.1"
  },
  "private": true
}

It works when I use admin.createUser() only but then I cannot use user.sendEmailVerification() because for some reasons its only available if the user is created using admin.createUserWithEmailAndPassword().

This is what I get in firebase console :

TypeError: admin.auth(...).createUserWithEmailAndPassword is not a function
    at /user_code/index.js:26:26
    at cloudFunction (/user_code/node_modules/firebase-functions/lib/providers/https.js:37:41)

    at _combinedTickCallback (internal/process/next_tick.js:73:7)
    at process._tickDomainCallback (internal/process/next_tick.js:128:9)

What do I do? Here,

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

I am new to firebase and cloud functions so apologies.

Answer 1

The message is telling you everything you need to know. There is no method of that name in the node admin SDK.

You can see a list of all the methods on admin.auth() in the API docs.

createUserWithEmailAndPassword only exists in the client SDK.

Answer 2

you just have to use auth().createUser instead of createUserWithEmailAndPassword

admin.auth().createUser({
 email: '[email protected]',
 emailVerified: false,
 phoneNumber: '+11234567890',
 password: 'secretPassword',
 displayName: 'John Doe',
 photoURL: 'http://www.example.com/12345678/photo.png',
 disabled: false
})
.then(function(userRecord) {
  // See the UserRecord reference doc for the contents of userRecord.
  console.log('Successfully created new user:', userRecord.uid);
})
 .catch(function(error) {
  console.log('Error creating new user:', error);
 });
