I just want to ask , I will build app using react native but the app has a feature which allow the user to add and save his recipe offline is that possible using firebase please I want anyone to answer me !
if yes please tell me how
If you use the Firestore database the offline capabiliteis are by default enabled.
Offline persistence is supported only in Android, iOS, and web apps.
You can read more about it here.
That means you work with the database as of it is a local one. It will sync automaticaly with the server when there is a connection. There are no futher instructions required. Just use it according to the documentation. The offline is by default integrated into it.

I'am new in Phantom/ Solana universe and I want to create my first web app using Phantom Wallet into my React app. I used the Phantom app documentation to connect to my wallet, that's work.
But now, I want to show in my app some data about the connected wallet like NFT possessed, solana balance and so on.
Does anyone know what should I do ?
Thank you in advance.
You can have my code for this. And will work fine.
CodeSandbox
But remember install #solana/web3.js v1.30.2
If you gone to higher version some extra dependencies and webpack config is needed.

I want to create an Admin page in order to manage users, groups, passwords and to publish content in a website. That website is made using React.
What is the right way to make it? Using a library for React that provides such Admin?
My workmate told me he uses Material UI, but I don't see how that library could be used for that purpose.
Material UI is used only for styling stuff, not for actual logic. If you have a REST backend, take a look at admin on rest project.
What is your backed written in?

I have a web application that I have created with angularJS/Symfony2 and a mobile app with(ionic) I want to create a real chat application between this 2 clients.I thought to use nodeJS and websockets??I can have many clients conncted from their mobile
I have read many articles about firebase for angularJS and redis,but I don't know from where I will start
have you please any idea how can I do that
thanks a lot
The simplest way to start is check basic chat solution on NodeJs http://socket.io/get-started/chat/
Also as alternative you can use Rachet(WebSockets for PHP) http://socketo.me/ to get more closer integration with Symfony2
You can definetely use node and socket.io.
Start here:

To integrate it with angular, you can use this module:

I'm currently building a Hybrid mobile app using ionicframework,angularjs and cordova,in my app i will need some data storage such as all users details.
What i'm trying to figure out is how to update the database for all users,for example if a new user signs up,he should be added to the database and everyone else should be able see his profile instantly,i'm thinking the database should be shared online instead of just updating the local database installed with the app,i'm currently using SQLite plugin to store such data but i'm not sure if it's the right choice for my case.
Does anyone know how to reach what i want ? i would appreciate any help.
Thanks.
Too many users then no point in storing and syncing. Creates more data inconsistency issues and resource consumption.
Online is the way to go.
If there is a subset of users whom u want to store information then thats an option.
Like watsapp stores and syncs information of those who are on your contact or chats only and not the whole watsapp db.
Thank you guys,after a lot of research,few days ago i decided to use Firebase,it's really powerful and works perfectly with angularJS and ionicframework which i'm using to build my app. I would really recommend it in situations similar to mine.

I have a SQLite database hosted in a server, e.g. http://www.webserver.com/database.db
I need to download this database into my phonegap/cordova application, in order to read its data offline.
Practically, I need to "clone" my external database into an internal one.
Please, could someone help me? Thanks.
A few things. First, PhoneGap does not supporting download a SQLite db file and then connect to it. I believe it is possible if I use a native plugin, but out of the box, I can't do it that way.
Solution: download raw data via XHR, i. e. JSON data, and then do imports.
