I'm trying to use the firebase in a react native project
I installed the firebase in my project:
npm install --save firebase
and I'm importing it into my app.js
import firebase from 'firebase';
import React, { Component } from 'react';
import {
Platform,
Text,
View
} from 'react-native';
type Props = {};
export default class App extends Component<Props> {
render() {
return (
<View >
<Text>Testando Firebase</Text>
</View>
);
}
}
and then the error is displayed:
Objects are not valida as a react child (found: object with
keys{&&typeof, type, key, ref, props, _owner, _store}). If you meant
to render a collection of children, use an array instead.
but when I remove the import from firebase, the app works perfectly.
Try to install the version 5.0.2. Use this command as administrator:
npm uninstall firebase
npm install --save firebase#5.0.2
As far as i see, the current version (5.0.4) is buggy!
You need to import as follow
import * as firebase from 'firebase';
You first must have firebase installed.
The solution is to uninstall the current version of Firebase and install an older version.
1st step npm uninstall firebase
2nd step npm i firebase#8.0.3
It was the version that worked for my case.

i install npm redux also npm react-redux
did these code inside index .js
import { createStore } from "redux";
import { Provider } from "react-redux";
const reducer=(State={count:0} ,action)=>{
return State;
}
const store= createStore(reducer)
root. Render(
<Provider >
<App />
</Provider>
here
but it seem it doesn't read [createstore][1] because at the terminal i saw msg with install redux make the location global
i changed in 4 file npm ,npm.exe ,xpn, xpn.exe and install redux and react-redux again by these commands again (npm i redux -global , npm i react-redux g same thing
i locked at json it seems all file in json package.lock is still same problem doesn't see create store i tried and i keep search it still same any help please
consider adding store prop to the Provider component eg.:
<Provider store={store}>
To make your code cleaner, I recommend you to create your store in a separate file and export it there ..
Then in index.js, import the store and provide it to the Provider component as we did above

I am trying to import firebase in my react app, using the following syntax:
import firebase from "firebase";
But I am facing following issue:
./src/firebase.js
Module not found: Can't resolve 'firebase' in '/Users/Desktop/reels/src'
commands i have ran on terminal:
npm i firebase
Also i have checked in the node modules firebase was there.
You should try this code
import { initializeApp } from "firebase/app";
import { getFirestore } from "firebase/firestore";
I think you're using the ^9 version, so try this:
import firebase from 'firebase/compat/app'
I want to import the firebase-database using esm import. I can only find the script version:
<script src="https://www.gstatic.com/firebasejs/7.21.0/firebase-database.js"></script>
What is the url I need for the esm module version?
Note: I do not want a "bare import", I am not using webpack etc. I need a complete url.
There is an older version available on unpkg.com but not the current version.
It turns out there are two CDN's that can provide this: snowpack/skypack, and jspm:
skypack:
import firebase from 'https://cdn.skypack.dev/#firebase/app'
import 'https://cdn.skypack.dev/#firebase/database'
jspm:
import { firebase } from 'https://jspm.dev/#firebase/app'
import 'https://jspm.dev/#firebase/database'
These both deal with "bare import" conversion to JS, and any code conversions required to be JS Modules.
Google does not appear to want to support a module form on their firebase CDN, an Issue to that effect was immediately closed, suggesting complex workflow solutions.
I'm really thankful to the two projects above, supporting simple es6 JS and zero workflow solutions.
Edit: snowpack's esinstall can turn most js files into modules. Here's a node script that brought in all my dependencies:
#!/usr/bin/env node --require esm
import { install } from 'esinstall'
import nodePolyfills from 'rollup-plugin-node-polyfills'
async function run() {
const foo = await install(
[
'mapbox-gl',
'three',
'three/examples/jsm/controls/OrbitControls.js',
'three/src/core/Object3D.js',
'chart.js',
'dat.gui',
'fflate',
'#turf/turf',
'stats.js',
'#firebase/app',
'#firebase/database',
],
{
rollup: {
plugins: [nodePolyfills()],
},
}
)
}
run()
If you're using a bundler, then follow the instructions in the documentation:
Install the firebase npm package and save it to your package.json file
by running:
npm install --save firebase
To include only specific Firebase products (like Authentication and
Cloud Firestore), import Firebase modules:
// Firebase App (the core Firebase SDK) is always required and must be listed first
import * as firebase from "firebase/app";
// If you enabled Analytics in your project, add the Firebase SDK for Analytics
import "firebase/analytics";
// Add the Firebase products that you want to use
import "firebase/auth";
import "firebase/firestore";
For realtime database, you would add import "firebase/database".
I'm trying to add SQlite to my ionic4 project, but get installation errors.
My NPM install was this:
ionic cordova plugin add cordova-sqlite-storage
npm install #ionic-native/sqlite
//ionic plugin add cordova-sqlite-storage ==> this one makes error
In main.js, I tried each of the following:
import SQLite from 'ionic-native';
import {SQLite} from 'ionic-native';
import SQLite from '#ionic-native/sqlite';
import {SQLite} from '#ionic-native/sqlite';
import { SQLite, SQLiteObject } from '#ionic-native/sqlite';
Here are the errors: a) npm warning, b) console error, and c) Chrome inspector for main.js
And here's the code from main.js (last line is where everything fails).
new Vue({
el: '#app',
router,
template: '<App/>',
components: { App },
render : (h) => h(App),
mounted() {
this.storage = new SQLite();
*** I marked this question as answered, but there appears to be no answer yet. I'll keep working on it.
#ionic/vue is still in beta and the team is working on integrating it with the Vue CLI. They are also using Capacitor, not Cordova, as the official native bridge for this project. As such it is recommended to use Capacitor if at all possible. Should you go that route, their storage API is available in lieu of SQLite.
If you would like to persist with your Cordova project, the Ionic Storage abstraction won't be available so you would have to bypass Ionic altogether.
Install the plugin using the Cordova CLI (#ionic-native/sqlite is not required):
cordova plugin add cordova-sqlite-storage
Use the plugin directly e.g.
const db = window.sqlitePlugin.openDatabase({...})
db.executeSql('INSERT...', [...values], callbackFn, errorFn)
I would like to know how to use React components from npm in Meteor 1.3 using import.
I am trying to use react-gravatar in my project. I did npm install --save react-gravatar. And in my component, I required it:
import React from 'react';
import Gravatar from 'react-gravatar';
export default React.createClass({
render() {
...
}
});
But I get:
Uncaught Error: Cannot find module 'querystring'
I think this is because querystring is not available in client side, and I need to use browserify-reactify of some sort. But how can I do so in Meteor 1.3?
