React Native - Multithreading - reactjs

I have a mobile app built using react-native.
With this app, user takes hundreds of photos
The photos need to be uploaded to S3 ASAP
Wondering if react-native supports multithreading so that we can process uploads faster

Yes, you can use z.B. react-native-workers.

Building a desktop admin panel for react native app

I am building a react native app with firebase auth and cloud storage, and I was just wondering if it is possible to make a dashboard for desktops to administrate the users/app? And if it does, how do I do this? Is it in the same build, or do I have to build a new "app" for adminpanel/dashboard?
This is my first time building the adminpanel/backend xD
While it's possible to build web apps with React Native, I wouldn't recommend it. The Layout of a desktop is just way too different from phones to build React Native Apps including web without constantly using Platform.OS. In your question, you even mention that you wan't the dashboard to just be available on the desktop but not on the Phone (which makes sense in my opinion). Since you seem to know a bit about React Native, it should be an easy thing for you to build the Dashboard as a different Application with React for the web only.

What is a possible way to create an in app PDF viewer with React Native and Expo?

I'm working on an app for a financial company. They want the statements which are in PDF be accessible within the app for viewing. I'm having a hard time finding a solution since any libraries with a PDF reader would require ejecting from expo which I need to avoid.
I've been trying to use the expo-web-browser hoping I can keep it contained within the app kind of like how it works with authentication.
Any insights?

Is there any database that we can use for react-native(ios and android) and react-native-web app that have same code base?

I am planning to develop a react native app for mobile and the same code base for web app . My app should work offline storing the data in some sort of database, is there any database that will work both in mobile and web for react native?
I have looked into Realm and PouchDB, Realm and pouch will work in react-native mobile. I don't have any clarity on whether they will work on web app.
yes you can use sqlite for this purpose it will work on both ends.
I use sqlite https://www.npmjs.com/package/react-native-sqlite-storage it will work for both ios and android

Creating a Native iOS App for an Existing Rails App

Okay, so I'm running a Rails 3.1 app hosted on engine yard. I'd like to create a native iOS app which will run off the same database as the web app.
However, where the web app supports full CRUD, I only want to be able to do two things with the app:
Fetch data from the database [eg: MP3 Names]
Play the MP3s within the app.
Any suggestions of frameworks from anyone? :) It'd be much appreciated.
If you intend on building out the app more, I'd take a look at RestKit. It has some great stuff included to help cache data on the iphone and synch between iOS and the Rails app.
If you aren't planning on things getting more complicated than what you have described above, you may be better off using something a little more lightweight check out RestClient or LRResty
