I build an app with Expo tool .. but now I what to move to react native without expo .. I tried to just create a new project in react native and then transfer the code that I had written and install components that I had used in my app .
the app with Expo work as expected put with moved to react native without Expo works as unexpected and crashes.
you don't need to transfer the code like that, the expo provides us to detach our code from expo to without expo react-native projects.
please refer to this link expokit eject
if you want to use expo API in your project then you can detach your app using detach-with-expokit.
use expo eject to add ExpoKit (choose the "ExpoKit" option).

I was wondering if I could use Expo to run the react-native project that I created using the npx react-native init command, since it generates a better structure for real-world applications.
The reason I want to do this is to avoid the countless erros that I had while running and debugging the app.
You can't do that..
React native and expo are different.
You can run expo projects on react native by detaching them. Expo has limitations.
You can not run react native projects on expo, i.e projects made by react native init/npx can't run on expo
You can use a package made available by the expo
react-native-unimodules
for any React Native project using some resources made available by the expo.
react-native-unimodules
While creating an app in react native, I didn't get sub directories like android,or IOS. I Used create-react-native-app command.
New version of CRNA integrates Expo Toolkit, and android and ios folders are hidden. If you want to separate these folders, you must detach expo from react native app.
npm run reject
You can read more detail at CRNA's github
I found that create-react-native-app is based on expo. but when using exp-cli, it is also based on Expo.
what are differences between create-react-native-app and exp init ?
Updated answer:
create-react-native-app was replaced by expo-cli.

Answer to this question is well documented in expo documentation
Expo & "Create React Native App"
Create React Native App lets you build a React Native app without any
build configuration. This may sound familiar to you because Expo does
this as well -- when you create a project with XDE or exp you don't
have to deal with Xcode or Android Studio configuration files, it just
works. This guide is intended to outline some of the key differences
between Expo and CRNA (create-react-native-app).
CRNA does not require you to have an Expo account
You can run create-react-native-app YourAppName and off you go. So what does not
having an account mean, and what would signing up and using XDE/exp
get you -- why do we require it with Expo? Having an Expo account
allows you to do the following:
Publish your project to a permanent URL, eg:https://expo.io/#community/reactconf2017.See Publishing on Expo for more information.
Build binaries for app / play store distribution. To do this with CRNA without using Expo,
you would need to run eject.
There are advantages and disadvantages to either:
React Native app advantage:
You can add native modules written in Java/Objective-C
React Native app disadvantage:
Needs Android Studio and XCode to run the projects
Expo advantages:
Setting up a project is easy and can be done in minutes
Expo can build .apk and .ipa files
You do not need simulator to run your app.
Expo disadvantages:
You can't add native modules.
Your final app will bigger with expo init than with react native app init.
I suggest you read this:

In plugin they mentioned that the razorpay is not going to work with expo. i want to acces razorpay plugin in my react native app. is there any way..? i am using expo. please help me
if the react native library you want requires a linking step, then you can detach and use ExpoKit directly.
https://docs.expo.io/versions/latest/guides/detach.html
EAS builds officially released in Expo SDK 42 makes it possible to run native modules on expo projects.
In order to make sure Razorpay wrapper works correctly:
Create a dev build of your expo app by following the instructions mentioned here.
run your project by running the following command
For ios
expo run:ios
For android
expo run:android
I'm trying to use create-react-native-app as per the documentation with an example project that was built using instructions for react-native.
In terms of translating from one to the other what are the steps involved?
Edit: So i can run the app using npm start, with the expo.io QR code appearing as an option etc?
Create-react-native-app create a new project with Expo, you can eject it to turn it into a react-native project (android/ios folders with native code + src folder with javascript code).
You'll need an Xcode/Android Studio environment to run a react-native app built without Expo.
You can't use Expo to run a React-Native app with custom native code.
