Not really "migrating" our app per se, but actually we are building a new version from scratch using React Native.
We will be using the same BundleID etc etc so that this update just installs over the top of the last app.
What we would like to do though, is have access to the SQLite database that existed in the Appcelerator project.
From reading a few articles it seems like it should be possible, however everytime I connect my new app to the simulator or use and Ad Hoc build to update from the previous version, it seems that the database is empty.
database.js
import SQLite from 'react-native-sqlite-storage';
SQLite.DEBUG(true);
SQLite.enablePromise(true);
export default class DbTest {
static listTables(callback) {
const errorCB = err => {
console.log('SQL Error: ' + err);
};
return SQLite.openDatabase({name: '_alloy_'}, callback, errorCB);
}
}
App.js
saveToState(db) {
db.transaction(tx => {
tx.executeSql('select * from sqlite_master', [], (_, results) => {
console.log('Query completed', results);
this.setState(previousState => ({results}));
// Get rows with Web SQL Database spec compliance.
});
});
}
componentDidMount() {
DbTest.listTables(this.saveToState);
}
If I log out what results has in it I get
LOG Query completed {"insertId": undefined, "rows": {"item": [Function item], "length": 0, "raw": [Function raw]}, "rowsAffected": 0}
LOG SQLite.backgroundExecuteSqlBatch({"dbargs":{"dbname":"_alloy_"},"executes":[{"qid":1111,"sql":"COMMIT","params":[]}]})
LOG SQLite.backgroundExecuteSqlBatch({"dbargs":{"dbname":"_alloy_"},"executes":[{"qid":1111,"sql":"BEGIN","params":[]},{"qid":1111,"sql":"select * from sqlite_master","params":[]}]})
If anyone has any experience or can point me to an article I would be very grateful.
Thanks.
Run your Appcelerator app in the simulator or on a device. Then go grab the "alloy" database using Finder and put it into your React project. I open and query the database created when I install my apps on a simulator all the time using DB Browser for SQLite.

Error: "Cloud Fire Error: functions predeploy error: Command terminated with non-zero exit code 1"
I have a view all users screen in my application. On this screen, I have access to both email and uID. I need to build functionality that I can click a delete user button on the users tile. This should then delete the user from firebase authentication and the users collection in firebase. I seen from other posts that the best way for this would be to create a cloud function which I have tried from firestore documentation. I am getting the below error. The code I am trying is from firestore documentation and is as follows:
getAuth()
.deleteUser(uid)
.then(() => {
console.log('Successfully deleted user');
})
.catch((error) => {
console.log('Error deleting user:', error);
});
Attaching documentation link - https://firebase.google.com/docs/auth/admin/manage-users#node.js_7
Any advice is much appreciated.
This may happen because:
You don't have eslint installed. This could happen if at the time you ran firebase init functions you answered no when prompted Do you want to use ESLint to catch probable bugs and enforce style? and/or you answered no when prompted to install dependencies. If that's the case reinitialize the environment to get it installed.
You're missing the eslint package in your package.js file. To check/fix this open it up and look if you have something in the lines of:
"devDependencies": {
"eslint": "^4.12.0",
"eslint-plugin-promise": "^3.6.0"
},
As stated by #Werner7, that is also a possible solution.
Edit upon reading your question again:
This isn't a direct answer to your question but just a few things to note...
You essentially have 2 options here - deleting the user form the front end or firebase functions - each is slightly different.
Front end - You need to pass the user object into deleteUser() not the user's uid, and vice versa passing in the uid.
Firebase function example:
return admin.auth().getUserByEmail(data.email).then(user => {
return admin.auth().deleteUser(user.uid);
}).then(() => {
return {
massage: `Success, ${data.email} has been deleted.`
}
}).catch(err => {
return err;
});
Front end example:
import { getAuth, deleteUser } from "firebase/auth";
const auth = getAuth();
const user = auth.getUser(uid)
deleteUser(user).then(() => {
// User deleted.
}).catch((error) => {
// An error ocurred
// ...
});

I am getting an error in nuxt3 then setting up this amplify plugin. I am trying to add auth to nuxt3 via plugins
plugins/amplify.js
import Amplify, {withSSRContext} from 'aws-amplify';
export default defineNuxtPlugin((ctx) => {
const awsConfig = {
Auth: {
region: "ap-south-1",
userPoolId: "ap-south-1_#########",
userPoolWebClientId: "#####################",
authenticationFlowType: "USER_SRP_AUTH",
},
};
Amplify.configure({ ...awsConfig, ssr: true });
if (process.server) {
const { Auth } = withSSRContext(ctx.req);
return {
provide: {
auth: Auth,
},
};
}
return {
provide: {
auth: Auth,
},
};
}
[nuxt] [request error] Identifier 'module' has already been declared
at Loader.moduleStrategy (internal/modules/esm/translators.js:145:18)
at async link (internal/modules/esm/module_job.js:67:21)
Does anyone know what's going on?
Been facing this myself... I don't think its a nuxt problem but rather Vite.
I gave up on running the app on dev mode and just resorted to building the app and launching it. Also, in order to use aws-amplify with vite you need to apply some workarounds:
https://ui.docs.amplify.aws/vue/getting-started/troubleshooting
For the window statement (which only makes sense on the browser) you'll need to wrap that with an if statement. Added this to my plugin file
if (process.client) {
window.global = window;
var exports = {};
}
This will let you build the project and run it with npm run build . Far from ideal but unless someone knows how to fix that issue with dev in vite...
BTW, you can also just switch to webpack builder on nuxt settings and the issue goes away.
// https://v3.nuxtjs.org/api/configuration/nuxt.config
export default defineNuxtConfig({
builder: "webpack"
});
I think this might be a problem with auto imports of nuxt.
I added a ~/composables/useBucket.ts file which I used in ~/api. Same error started popping up the next day. After I moved ~/composables/useBucket.ts to ~/composablesServer/useBucket.ts issue disappeared.
I have a meteor app and want to migrate non-meteor app. I found account-js is compatible with the meteor account system. When I create new user everything works well but If I want to login with already existed user account-js methods does not work and I get unauth message everytime. How to login with already existed users by using account-js ?
const accountsPassword = new AccountsPassword({
verifyPassword: (plainPassword, storedPassword) => {
const hashedPassword = crypto.Hash('sha256').update(plainPassword).digest('hex')
console.log('*****Verify Password*****')
return bcrypt.compareSync(plainPassword, storedPassword)
}
})
const accountsServer = new AccountsServer(
{
db: accountsMongo
},
{
password: accountsPassword
}
)
const accountsGraphQL = AccountsModule.forRoot({ accountsServer })
const schema = makeExecutableSchema({
typeDefs: mergeTypeDefs([typeDefs, accountsGraphQL.typeDefs]),
resolvers: mergeResolvers([resolvers, accountsGraphQL.resolvers]),
schemaDirectives: {
...accountsGraphQL.schemaDirectives
}
})
const schemaMiddleware = applyMiddleware(schema, permissions)
accounts-js utilizes an entirely different authentication mechanism than Meteor authentication system. accounts-js uses JWT tokens while Meteor uses unique hashes so it's not cross-compatible. I wrote a blog post about it which you can read here
I am trying to develop a server-side validation of my users' in-app purchases and subscriptions as recommended, and I want to use Firebase Functions for that. Basically it has to be an HTTP trigger function that receives a purchase token, calls the Play Developer API to verify the purchase, and then does something with the result.
However, calling many of the Google APIs (including Play Developer API) requires non-trivial authorization. Here's how I understand the required setup:
There has to be a GCP project with Google Play Developer API v2 enabled.
It should be a separate project, since there can be only one linked to Play Store in the Google Play Console.
My Firebase Functions project must somehow authenticate to that other project. I figured that using a Service Account is most suitable in this server-to-server scenario.
Finally, my Firebase Functions code must somehow obtain authentication token (hopefully JWT?) and finally make an API call to get a subscription status.
The problem is that absolutely no human-readable documentation or guidance on that is existent. Given that ingress traffic in Firebase is included in the free plan (so I assume they encourage using Google APIs from Firebase Functions), that fact is pretty disappointing. I've managed to find some bits of info here and there, but having too little experience with Google APIs (most of which required simply using an api key), I need help with putting it together.
Here's what I figured out so far:
I got a GCP project linked to the Play Store and with the API enabled. For some reason though, trying to test it in APIs Explorer results in an error "The project id used to call the Google Play Developer API has not been linked in the Google Play Developer Console".
I made a Service Account and exported a JSON key, which contains the key to produce a JWT.
I also set up read permissions for that Service Account in Play Console.
I found a Node.JS client library for Google APIs, which is in alpha and has very sparse documentation (e.g. there's no obvious documentation on how to authenticate with JWT, and no samples on how to call the android publisher API). At the moment I'm struggling with that. Unfortunately I'm not super-comfortable with reading JS library code, especially when the editor doesn't provide the possibility to jump to highlighted functions' sources.
I'm pretty surprised this hasn't been asked or documented, because verifying in-app purchases from Firebase Functions seems like a common task. Has anyone successfully done it before, or maybe the Firebase team will step in to answer?
I figured it out myself. I also ditched the heavyweight client library and just coded those few requests manually.
Notes:
The same applies to any Node.js server environment. You still need the key file of a separate service account to mint a JWT and the two steps to call the API, and Firebase is no different.
The same applies to other APIs that require authentication as well — differing only in scope field of the JWT.
There are a few APIs that don't need you to exchange the JWT for an access token — you can mint a JWT and provide it directly in Authentication: Bearer, without a round trip to OAuth backend.
After you've got the JSON file with the private key for a Service Account that's linked to Play Store, the code to call the API is like this (adjust to your needs). Note: I used request-promise as a nicer way to do http.request.
const functions = require('firebase-functions');
const jwt = require('jsonwebtoken');
const keyData = require('./key.json'); // Path to your JSON key file
const request = require('request-promise');
/**
* Exchanges the private key file for a temporary access token,
* which is valid for 1 hour and can be reused for multiple requests
*/
function getAccessToken(keyData) {
// Create a JSON Web Token for the Service Account linked to Play Store
const token = jwt.sign(
{ scope: 'https://www.googleapis.com/auth/androidpublisher' },
keyData.private_key,
{
algorithm: 'RS256',
expiresIn: '1h',
issuer: keyData.client_email,
subject: keyData.client_email,
audience: 'https://www.googleapis.com/oauth2/v4/token'
}
);
// Make a request to Google APIs OAuth backend to exchange it for an access token
// Returns a promise
return request.post({
uri: 'https://www.googleapis.com/oauth2/v4/token',
form: {
'grant_type': 'urn:ietf:params:oauth:grant-type:jwt-bearer',
'assertion': token
},
transform: body => JSON.parse(body).access_token
});
}
/**
* Makes a GET request to given URL with the access token
*/
function makeApiRequest(url, accessToken) {
return request.get({
url: url,
auth: {
bearer: accessToken
},
transform: body => JSON.parse(body)
});
}
// Our test function
exports.testApi = functions.https.onRequest((req, res) => {
// TODO: process the request, extract parameters, authenticate the user etc
// The API url to call - edit this
const url = `https://www.googleapis.com/androidpublisher/v2/applications/${packageName}/purchases/subscriptions/${subscriptionId}/tokens/${token}`;
getAccessToken(keyData)
.then(token => {
return makeApiRequest(url, token);
})
.then(response => {
// TODO: process the response, e.g. validate the purchase, set access claims to the user etc.
res.send(response);
return;
})
.catch(err => {
res.status(500).send(err);
});
});
These are the docs I followed.
I think I found a slightly quicker way to do this... or at least... more simply.
To support scaling and keep index.ts from growing out of control... I have all the functions and globals in the index file but all the actual events are handled by handlers. Easier to maintain.
So here's my index.ts (I heart type safety):
//my imports so you know
import * as functions from 'firebase-functions';
import * as admin from "firebase-admin";
import { SubscriptionEventHandler } from "./subscription/subscription-event-handler";
// honestly not 100% sure this is necessary
admin.initializeApp({
credential: admin.credential.applicationDefault(),
databaseURL: 'dburl'
});
const db = admin.database();
//reference to the class that actually does the logic things
const subscriptionEventHandler = new SubscriptionEventHandler(db);
//yay events!!!
export const onSubscriptionChange = functions.pubsub.topic('subscription_status_channel').onPublish((message, context) => {
return subscriptionEventHandler.handle(message, context);
});
//aren't you happy this is succinct??? I am!
Now... for the show!
// importing like World Market
import * as admin from "firebase-admin";
import {SubscriptionMessageEvent} from "./model/subscription-message-event";
import {androidpublisher_v3, google, oauth2_v2} from "googleapis";
import {UrlParser} from "../utils/url-parser";
import {AxiosResponse} from "axios";
import Schema$SubscriptionPurchase = androidpublisher_v3.Schema$SubscriptionPurchase;
import Androidpublisher = androidpublisher_v3.Androidpublisher;
// you have to get this from your service account... or you could guess
const key = {
"type": "service_account",
"project_id": "not going to tell you",
"private_key_id": "really not going to tell you",
"private_key": "okay... I'll tell you",
"client_email": "doesn't matter",
"client_id": "some number",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://accounts.google.com/o/oauth2/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_x509_cert_url": "another url"
};
//don't guess this... this is right
const androidPublisherScope = "https://www.googleapis.com/auth/androidpublisher";
// the handler
export class SubscriptionEventHandler {
private ref: admin.database.Reference;
// so you don't need to do this... I just did to log the events in the db
constructor(db: admin.database.Database) {
this.ref = db.ref('/subscriptionEvents');
}
// where the magic happens
public handle(message, context): any {
const data = JSON.parse(Buffer.from(message.data, 'base64').toString()) as SubscriptionMessageEvent;
// if subscriptionNotification is truthy then we're solid here
if (message.json.subscriptionNotification) {
// go get the the auth client but it's async... so wait
return google.auth.getClient({
scopes: androidPublisherScope,
credentials: key
}).then(auth => {
//yay! success! Build android publisher!
const androidPublisher = new Androidpublisher({
auth: auth
});
// get the subscription details
androidPublisher.purchases.subscriptions.get({
packageName: data.packageName,
subscriptionId: data.subscriptionNotification.subscriptionId,
token: data.subscriptionNotification.purchaseToken
}).then((response: AxiosResponse<Schema$SubscriptionPurchase>) => {
//promise fulfilled... grandma would be so happy
console.log("Successfully retrieved details: " + response.data.orderId);
}).catch(err => console.error('Error during retrieval', err));
});
} else {
console.log('Test event... logging test');
return this.ref.child('/testSubscriptionEvents').push(data);
}
}
}
There are few model classes that help:
export class SubscriptionMessageEvent {
version: string;
packageName: string;
eventTimeMillis: number;
subscriptionNotification: SubscriptionNotification;
testNotification: TestNotification;
}
export class SubscriptionNotification {
version: string;
notificationType: number;
purchaseToken: string;
subscriptionId: string;
}
So that's how we do that thing.
We have a large SPA using Firebase v2. We would like to upgrade to the new API, but we experience the following problem:
As the app is quite large, we have developed many integration tests, and for these tests we always need to reset the database and initialize it to a state, where some users exist. However, we found out there really is no such thing as creating a user on server anymore ( Firebase createUserWithEmailAndPassword method is undefined in node.js ), and we are quite unsure, how to upgrade the API and yet be able to reset and initialize the database from server.
Moreover, we are quite forced to do this upgrade, because we noticed that the Firebase v2, is still using the deprecated Graph API v2.0 for Facebook OAuth, and is not recommended for use after 8.8.2016. We understand that the Firebase v2 will probably not upgrade the calls to the Graph API, as the v2 is legacy. This, however, leaves us quite cornered for now.
Any help on this topic, please?
As of Firebase v3.3.0 you are able to create user accounts using Node, but the documentation isn't great on how to expose these methods.
In order to use the user management methods, you need to initialize an application in node using your Web API key, and not the Service Account config that is walked through in the setup guide.
// The Usual Service Account Init
// This will not contain any user management methods on firebase.auth()
this.app = firebase.initializeApp(
{
serviceAccount: 'path/to/serviceaccount/file.json',
databaseURL: 'https://mydbfb.firebaseio.com'
},
'MyAppName');
// Web Client Init in Node.js
// firebase.auth() will now contain user management methods
this.app = firebase.initializeApp(
{
"apiKey": "my-api-key",
"authDomain": "somedomain.firebaseapp.com",
"databaseURL": "https://mydbfb.firebaseio.com",
"storageBucket": "myfbdb.appspot.com",
"messagingSenderId": "SomeId"
},
'MyAppName');
You can grab your client api key from your Firebase console from the Web Setup guide
https://firebase.google.com/docs/web/setup
This is the only reference I could find that explicitly referenced the need to init with api key to get this to work.

Given below is a working example of creating Firebase user through Node.js
exports.addUser = function(req, res) {
var wine = req.body;
var email = req.body.email;
console.log(req.body);
var password = req.body.password;
var name = req.body.name;
console.log(“Creating user for -“+email+”-“+password);
var defaultAuth = admin.auth();
admin.auth().createUser({
email: email,
emailVerified: false,
password: password,
displayName: name,
disabled: false
})
.then(function(userRecord) {
console.log(“Created Firebase User successfully with id :”, userRecord.uid);
var wine = req.body;
wine.userId = userRecord.uid;
wine.timestamp = Date.now();
delete wine.password;
status = “201”;
var reply = JSON.stringify(wine);
db.collection(‘collname’, function(err, collection) {
collection.insert(wine, {safe:true}, function(err, result) {
if (err) {
wine.status = “200”;
wine.message = “An error occured”;
reply.set(‘status’,”201″);
res.status(201).send(wine);
} else {
console.log(‘Success: ‘ + JSON.stringify(result[0]));
status= “200”;
wine.status = “200”;
wine.message = “Account created Successfully”;
res.status(200).send(wine);
}
});
});
})
.catch(function(error) {
wine.message = “An error occured—“;
wine.status = “201”;
console.log(“User Creation onf Firebase failed:”, error);
res.status(201).send(wine);
});
}
