this.$firebase is undefined - firebase

I'm building my first Vue.js app, trying to use vuex with vuexfire.
//main.js
import firebase from 'firebase';
...
Vue.prototype.$firebase = firebase.initializeApp(config);
...
firebase.auth().onAuthStateChanged(() => {
/* eslint-disable no-new */
new Vue({
el: '#app',
store,
router,
render: h => h(App),
created() {
this.$store.dispatch('setDealsRef');
},
});
});
router.beforeEach((to, from, next) => {
const currentUser = firebase.auth().currentUser;
const requiresAuth = to.matched.some(record => record.meta.requiresAuth);
if (requiresAuth && !currentUser) {
next('/signin');
} else if (requiresAuth && currentUser) {
next();
} else {
next();
}
});
And:
//store/index.js
import Vue from 'vue';
import Vue from 'vue';
import Vuex from 'vuex';
import { firebaseMutations } from 'vuexfire';
...
Vue.use(Vuex);
const db = this.$firebase.firestore();
const dealsRef = db.collection('deals');
And:
//store/mutations.js
export default {
SET_USER(state) {
state.user = this.$firebase.auth().currentUser;
},
...
}
This complies OK, but throws TypeError: this.$firebase is undefined[Learn More] in the console.
Any idea what I'm doing wrong? I think I've read every relevant tutorial and StackOverflow questions, and tried everything.

When you do:
Vue.prototype.$firebase = firebase.initializeApp(config);
You add $firebase to the Vue instance. So for
this.$firebase
to work, the this should be a Vue insteance. In other words, that line must execute inside a Vue method/hook/computed/etc.
And the code you show, doesn't do that:
const db = this.$firebase.firestore();
in the code above, the this is the outer context. (Probably is window.)
So for it to work outside a Vue instance, you have to do:
const db = Vue.prototype.$firebase.firestore();
Provided the line above executes after (in time/order) the line where you initialize the $firebase.

I think I solved the problem:
Moving firebase initialization to store.js
Changing firebase.auth().onAuthStateChanged(() => { to Vue.prototype.firebase.auth().onAuthStateChanged(() => { in main.js
Importing firebase as: import firebase from '#firebase/app';
import '#firebase/firestore';

Vue + Pinia + Firebase Authentication: Fetch currentUser before Route Guard

Recently I started to use Pinia as a global store for my Vue 3 Project. I use Firebase for the user authentication and am trying to load the current user before Vue is initialized. Ideally everything auth related should be in a single file with a Pinia Store. Unfortunately (unlike Vuex) the Pinia instance needs to be passed to the Vue instance before I can use any action and I believe that is the problem. On first load the user object in the store is empty for a short moment.
This is the store action that is binding the user (using the new Firebase Web v9 Beta) in auth.js
import { defineStore } from "pinia";
import { firebaseApp } from "#/services/firebase";
import {
getAuth,
onAuthStateChanged,
getIdTokenResult,
} from "firebase/auth";
const auth = getAuth(firebaseApp);
export const useAuth = defineStore({
id: "auth",
state() {
return {
user: {},
token: {},
};
},
actions: {
bindUser() {
return new Promise((resolve, reject) => {
onAuthStateChanged(
auth,
async (user) => {
this.user = user;
if (user) this.token = await getIdTokenResult(user);
resolve();
},
reject()
);
});
},
// ...
}})
and this is my main.js file
import { createApp } from "vue";
import App from "./App.vue";
import router from "./router";
import { createPinia } from "pinia";
import { useAuth } from "#/store/auth";
(async () => {
const app = createApp(App).use(router).use(createPinia());
const auth = useAuth();
auth.bindUser();
app.mount("#app");
})();
How can I set the user before anything else happens?
I figured it out. Had to register the router after the async stuff
//main.js
(async () => {
const app = createApp(App);
app.use(createPinia());
const { bindUser } = useAuth();
await bindUser();
app.use(router);
app.mount("#app");
})();

Vue Reactivity: Creating reactive data with provide and inject

My aim is to validate a users' credentials from vue frontend, fetch their data, store the data in a globally available variable and use them in any component. After some work, I'm able to use Vue's reactive() method with inject and provide. Here's my current code:
In store/index.js
import { reactive, inject } from 'vue'
// global states
export const stateSymbol = Symbol('state')
export const createState = () => reactive({
backendRoute: 'http://127.0.0.1:8000/',
currentUser: {},
logIn: userData => {
let user = createState.currentUser
user = userData
console.log(user)
}
})
export const useState = () => inject(stateSymbol)
Then in main.js
import { createApp } from 'vue'
import App from './App.vue'
// store modules
import { stateSymbol, createState } from './store'
// create app
const app = createApp(App)
app.provide(stateSymbol, createState())
Then in login/register component named Login.vue
import { useState } from "../store"
import axios from 'axios'
export default {
name: 'RegisterLogin',
setup() {
let state = useState()
axios.get(getUser, jwtConfig).then(response => {
userId = response.data.id
const currentUser = getUserProfile+userId // URL
console.log(currentUser)
const getCurrentUser = axios.get(currentUser, jwtConfig)
getCurrentUser.then(response => {
state.logIn(response.data)
console.log(state.currentUser)
})
})
}
}
console.log(user) in store/index.js logs the userData as expected. I believe with that, createState.currentUser should be mutated. The problem however is console.log(state.currentUser) logs an empty proxy object. Also, if I try accessing the state.currentUser from another component like Home.vue:
<template>
{{ state.currentUser }}
</template>
<script>
import { useState } from '../store/'
export default {
name: 'Index',
setup() {
return {
state: useState(),
}
},
}
</script>
...an empty object is always displayed even after the user logs in successfully. Is there anything I'm doing wrong? Thank you for your assistance (in advance).
I was looking through the code but couldn't find anywhere where the variable was getting mutated, but I believe I know what's going on.
You are reassigning the user object, not assigning the createState.currentUser to another object.
import { reactive, inject } from 'vue'
// global states
export const stateSymbol = Symbol('state')
export const createState = reactive({
backendRoute: 'http://127.0.0.1:8000/',
currentUser: {},
logIn: userData => {
// over here you assign user to createState.currentUser
let user = createState.currentUser;
// then you reassign user to `user data`
user = userData
console.log(user)
}
})
export const useState = () => inject(stateSymbol)
you could instead try
import { reactive, inject } from 'vue'
// global states
export const stateSymbol = Symbol('state')
export const createState = () => reactive({
backendRoute: 'http://127.0.0.1:8000/',
currentUser: {},
logIn: userData => {
createState.currentUser = userData
console.log(createState.currentUser)
}
})
export const useState = () => inject(stateSymbol)
As an aside, why are you using inject? I can't figure out what you're expecting it to do.
export const useState = () => stateSymbol would have the same result, but you don't even need to pass the function, you can just use something more concise like...
//////// store
import { reactive } from 'vue'
// global states
export const store = reactive({
backendRoute: 'http://127.0.0.1:8000/',
currentUser: {}
})
export const logIn = (userData) => {
store.currentUser = userData
}
////////////////////////////////////////////////
////// main
import { store, logIn } from "../store"
import axios from 'axios'
export default {
name: 'RegisterLogin',
setup() {
axios.get(getUser, jwtConfig).then(response => {
userId = response.data.id
const currentUser = getUserProfile+userId // URL
console.log(currentUser)
const getCurrentUser = axios.get(currentUser, jwtConfig)
getCurrentUser.then(response => {
logIn(response.data)
console.log(store.currentUser)
})
})
}
}
It appears #Daniel was right after all. My logIn method in store/index.js was not really mutating the currentUser property. In fact, I'm unable to access that property from the method. To solve this, I had to do the mutation immediately after the axios call like state.currentUser = response.data in then method and boom, the state is updated in all components! Thanks.

firebase.auth.GoogleAuthProvider is not a constructor

I'm trying to use google sign using firebase in the Vue framework. I don't know what the error is this can anyone help me with this.
vue.runtime.esm.js?2b0e:1888 TypeError: _firebase_js__WEBPACK_IMPORTED_MODULE_2__.fb.auth.GoogleAuthProvider is not a constructor
at VueComponent.socialLogin (Signin.vue?3d55:76)

at HTMLButtonElement.invoker (vue.runtime.esm.js?2b0e:2179)
at HTMLButtonElement.original._wrapper (vue.runtime.esm.js?2b0e:6917)
this is my code
firebase.js
import firebase from "firebase";
var firebaseConfig = {
config
};
const fb=firebase.initializeApp(firebaseConfig);
export { fb };
Sign in.vue
<script>
import { fb } from "../firebase.js";
export default {
name: "Signin",
components: {},
data() {
return {
};
},
methods: {
socialLogin() {
const provider = new fb.auth.GoogleAuthProvider();
fb.auth().signInWithPopup(provider).then((result) => {
this.$router.replace('home');
}).catch((err) => {
alert('Oops. ' + err.message)
});
}
}
};
</script>
The auth property (not the auth() function) is available on the static firebase object, not your firebase app.
You want something more like this
import firebase from "firebase/app"
import "firebase/auth" // 👈 this could also be in your `firebase.js` file
const provider = new firebase.auth.GoogleAuthProvider()

firebase and gatsby build don't work well together

I get the following error when I try to login:
u.a.auth is not a function
The error is on this line in Login.js:
app.auth().setPersistence(firebase.auth.Auth.Persistence.NONE);
At the top, I have import app from "./base.js";
In base.js, I have
import firebase from 'firebase/app';
var config = {
....
};
var app;
if(firebase.apps && firebase.apps.length > 0) {
app = firebase.apps[0];
} else {
app = firebase.initializeApp(config);
}
export default app;
That's after I run
gatsby build
gatsby serve
Hello here's how I did it. It worked fine:
import React from "react";
import firebase from "firebase";
...
const LoginForm = () => {
const login = values => {
firebase
.auth()
.signInWithEmailAndPassword(values.email, values.password)
.then(() => { firebase.auth().setPersistence(firebase.auth.Auth.Persistence.SESSION);
navigate("/app/profile");
})
.catch(error => {
console.log("do something with the error:", error);
});
}
return(
<form onSubmit={login}>
form details
</form>
);
};
export default LoginForm;

React Redux Firebase: Error on firebaseConnect - Cannot read property 'ordered' of undefined

I followed the example in the documentation under v2.0.0 > Read Me > Load Data (listeners automatically managed on mount/unmount) (direct link is not possible).
And replaced the connect call with the firestore specific one shown here](http://react-redux-firebase.com/docs/firestore.html#examples) in Example 1.
I copied the Todo example exactly in a new component created for testing purposes.
Todo Component:
import React from 'react'
import PropTypes from 'prop-types'
import { connect } from 'react-redux'
import { compose } from 'redux'
import { firebaseConnect,firestoreConnect, isLoaded, isEmpty } from 'react-redux-firebase'
const Todos = ({ todos, firebase }) => {
// Build Todos list if todos exist and are loaded
const todosList = !isLoaded(todos)
? 'Loading'
: isEmpty(todos)
? 'Todo list is empty'
: Object.keys(todos).map(
(key, id) => (
<TodoItem key={key} id={id} todo={todos[key]}/>
)
)
return (
<div>
<h1>Todos</h1>
<ul>
{todosList}
</ul>
<input type="text" ref="newTodo" />
<button onClick={this.handleAdd}>
Add
</button>
</div>
)
}
// export default compose(
// firestoreConnect([
// 'todos' // { path: '/todos' } // object notation
// ]),
// connect((state) => ({
// todos: state.firestore.data.todos,
// profile: state.firestore.profile // load profile
// }))
// )(Todos)
export default compose(
firestoreConnect(['todos']), // or { collection: 'todos' }
connect((state, props) => ({
todos: state.firestore.ordered.todos
}))
)(Todos)
The store configuration was configured as shown here in the docs. The store configuration was adapted to slot into the framework created by react-boilerplate.
/**
* Create the store with dynamic reducers
*/
import { createStore, applyMiddleware, compose } from 'redux'
import { fromJS } from 'immutable'
import { routerMiddleware } from 'connected-react-router/immutable'
import createSagaMiddleware from 'redux-saga'
import { reactReduxFirebase, firebaseReducer } from 'react-redux-firebase'
import { reduxFirestore, firestoreReducer } from 'redux-firestore'
import firebase from 'firebase/app'
import 'firebase/auth'
import 'firebase/database'
import 'firebase/firestore'
import createReducer from './reducers'
const sagaMiddleware = createSagaMiddleware()
const firebaseConfig = {
apiKey: process.env.FIREBASE_API_KEY,
authDomain: process.env.AUTH_DOMAIN,
databaseURL: process.env.DATABASE_URL,
projectId: process.env.PROJECT_ID,

}
const rrfConfig = {
userProfile: 'users',
// useFirestoreForProfile: true, // Firestore for Profile instead of Realtime DB
// attachAuthIsReady: true
}
// Initialize Cloud Firestore through Firebase
export default function configureStore(initialState = {}, history) {
firebase.initializeApp(firebaseConfig)
// Initialize Firestore with timeshot settings
firebase.firestore()
// firebase.firestore().settings({ timestampsInSnapshots: true })
// Create the store with two middlewares
// 1. sagaMiddleware: Makes redux-sagas work
// 2. routerMiddleware: Syncs the location/URL path to the state
const middlewares = [sagaMiddleware, routerMiddleware(history)]
const enhancers = [
applyMiddleware(...middlewares),
// reactReduxFirebase(config), // enhancing our store with these packages
// reduxFirestore(config)
]
// If Redux DevTools Extension is installed use it, otherwise use Redux compose
/* eslint-disable no-underscore-dangle, indent */
const composeEnhancers =
process.env.NODE_ENV !== 'production' &&
typeof window === 'object' &&
window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__
? window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__({})
: compose
/* eslint-enable */
const createStoreWithFirebase = compose(
reactReduxFirebase(firebase, rrfConfig), // firebase instance as first argument
reduxFirestore(firebase),
)(createStore)
const store = createStoreWithFirebase(
createReducer(),
fromJS(initialState),
composeEnhancers(...enhancers),
)
// Extensions
store.runSaga = sagaMiddleware.run
store.injectedReducers = {} // Reducer registry
store.injectedSagas = {} // Saga registry
// Make reducers hot reloadable, see http://mxs.is/googmo
/* istanbul ignore next */
if (module.hot) {
module.hot.accept('./reducers', () => {
store.replaceReducer(createReducer(store.injectedReducers))
})
}
return store
}
I traced and verified my store configuration exactly to make sure all steps present in the documentation are configured correctly in my configuration.
My createReducer funciton is in a seperate file and you can see that I added the firebaseReducer and firebaseReducer correctly.
import { combineReducers } from 'redux-immutable'
import { connectRouter } from 'connected-react-router/immutable'
import { firebaseReducer } from 'react-redux-firebase'
import { firestoreReducer } from 'redux-firestore'
import history from 'utils/history'
import languageProviderReducer from 'containers/LanguageProvider/reducer'
export default function createReducer(injectedReducers = {}) {
const rootReducer = combineReducers({
firebase: firebaseReducer,
firestore: firestoreReducer,
language: languageProviderReducer,
...injectedReducers,
})
// Wrap the root reducer and return a new root reducer with router state
const mergeWithRouterState = connectRouter(history)
return mergeWithRouterState(rootReducer)
}
My redux store contains the firestore and firebase and it is injected into the component props.
What does not work is the use of connectFirestore HoC to automatically retrieve and inject a list of documents in to the component.
This is the error message:

(Snipped from my code which is the example 1 in documentation):
export default compose(
firestoreConnect(['todos']), // or { collection: 'todos' }
connect((state, props) => ({
todos: state.firestore.ordered.todos
}))
)(Todos)
I inspected the state variable and it does contain the firestore attribute. This attribute contains a number of functions, as expected, but it is missing the query results under "ordered", which is undefined.
I have tried all different ways to use firestoreconnect e.g. using a Class-based component, using a query with parameters, etc. and all give the same error.
My Firebase project is configured correct as I am able to create documents inside collections. A todos collection for testing purposes is present as well containing 2 documents.
I have come across this post, which mentions the following:
If you just upgraded to React-Redux v6, it's because react-redux-firebase is not compatible with v6.
See https://github.com/prescottprue/react-redux-firebase/issues/581 for details.
This does not apply to me because I am using react-redux version 5. Here are the versions I am using:
"firebase": "^5.10.1",
"react-redux": "^5.0.7",
"react-redux-firebase": "^2.2.6",
"redux": "^4.0.1",
"redux-firestore": "^0.7.3",
I have spent a significant amount of time on this. Like I said, using firestore to add new data to collections works fine. It is just this HoC business that is failing no matter how i approach the solution.
any help would be appreciated.
Never solved this. I guess it is related to incompatible versions. What I ended up doing is download v4 of react-boilerplate and set up v3 react-redux-firebase which uses the Context API as opposed to store enhancers. Now works very well.
