This is my Code which is showing this error . Here I am trying to make a Drawer-navigation
This is the error showing , I am doing this in react-native.
It seems you might have missed some installation / setup steps for react-navigation.
Please check this section in the docs: https://reactnavigation.org/docs/getting-started#installing-dependencies-into-a-bare-react-native-project
If you have already installed the packages listed there (notably react-native-reanimated), perhaps you have not installed the native dependencies. This is important on iOS - run npx pod-install in your project root, and then build the app again (hot reload will not be enough).

Currently, my project running on the 0.66.3 version I need to upgrade to react native version 0.70.6. So I have used to following command
npx react-native upgrade
After running this command showing some error I have attached a screenshot please refer.
I am also trying the manual way using react native helper but some files are not available in my project.
so anyone please tell me how I will upgrade my project version?
After Run npx react-native run-android my build was created successfully but 3 errors showing in the metro bundler. I have attached a screenshot of the metro bundler error.
you can specify a React Native version and pass it as an argument:
npx react-native upgrade 0.70.6
you can also refer this official documentation for this
& it will also helps you if you got any error.
https://reactnative.dev/docs/upgrading
I found by changing react-native - index.js and react-native/Libraries/Text - index.js
Follow this link for output:
https://github.com/facebook/react-native/commit/3f629049ba9773793978cf9093c7a71af15e3e8d
Don't know whether it is the right way or not....
Since upgrading an application can break functionality in your app if you do not know what is needed to be changed. the upgrade is tells you to visit the pages to go through and see what has changed throughout the upgrading process.
Other as that I am just needing more information regarding to what is not working. Since upgrading is more as just running a command, its about reading the documentation and see what part is missing and what they replaced the files with. The missing files could be straight-out deprecated and not working with the new version.
As always check the debugger and read every message throughout and visit all links given and see the documentation regarding the upgrade differences, find out if there are any log files you could look at, and talk with people in your company / group of react-native about this.
"Some files are not available in my project"
This part might just be able to google and see if this is still supported or not in the version it could be phased out, or not supported in the version. that's where versioning comes in to play.
I am unsure what files and which libraries are deprecated based on your Opening Post, this needs more information, to help us, help you.
I just updated to Expo 43.0 in a bare workflow project and followed the guide on how to update the app to also use expo-modules-core. The app runs in dev mode and can compile to both Android and iOS. However, when running react-native-start the following message is shown in the terminal:
warn Package expo-modules-core has been ignored because it contains invalid configuration. Reason: "dependency.platforms.ios" must be of type object
Then the metro server starts. I have tried searching for others with similar issues, does anyone know what may be causing this?
I followed this guide: https://docs.expo.dev/bare/installing-expo-modules/
This warning is coming from react-native-community autolinking. it looks like the api changed and they don't accept null values anymore, but this is what they still specify in their docs. the behavior you see is expected still - expo-modules-core is and should be ignored by react-native-community autolinking, because it's handled by expo autolinking. so, this won't impact your project and it's a warning caused either by an accidental regression or undocumented change in react-native-community autolinking.
https://github.com/expo/expo/issues/16085
Yes, it is coming from react-native. So for resolving this issue you have to remove the react-native.config.js file from node_modules
Follow the bellow steps:-
Go to node_modules/expo-modules-core
Delete react-native.config.js
I would like to know if it's necessary to rebuild react native project after installing and linking libraries that includes native codes.
Yes, as react-native-link updates some native files that are under the ios/android folder, that won't be checked during a reload/hot-reload/live-reload. All those files aren't checked in your jsBundle and are compiled during a run-android or run-ios.
Of course, if you added a new dependecy to the project and linked it, and you haven't used it anywhere in your code yet, you don't need it. If you are using that dependecy, your project instance will, most likely, die.
if your react native version is below 0.60 then you have to run react-native-link after you install any react-native module. However after react-native version 0.60 and above, this is done automatically using the new "autolinking" feature added.
Read the changelog here:
https://facebook.github.io/react-native/blog/2019/07/03/version-60
However you still need to rebuild your project after you install a native module but you dont need to run the react-native-link command anymore after installing every library after react-native#0.60 and above. Just type react-native run-android
What is the purpose of the react-native link command?
Note: from React-Native 0.60.0 linking packages using react-native link has become redundant. Autolink has been added to the React-Native CLI which means that iOS will now use cocoapods and Android will use gradle. You can read more about Autolinking here.
What is react-native link?
react-native link is an automatic way for installing native dependencies. It is an alternative to manually linking the dependency in your project. It works for both Android and iOS.
When linking a project manually the majority of the steps are the same and so using react-native link allows you to install the native dependency with less fuss and without having to type similar code or perform similar actions repeatedly.
However, it should be noted that running react-native link will not always link a package fully, sometimes additional steps are required and you should check carefully with the installation instructions.
Always read the instructions carefully before installing a dependency and linking it.
iOS Considerations
If your project is using CocoaPods and the dependency that you are linking has a .podspec then when you use run react-native link it will update your Podfile. This is instead of adding the files directly to your Xcode project. You will also have to run pod install inside your ios directory otherwise the native dependency won't be fully installed.
Sometimes installing using CocoaPods can cause more issues, and not every dependency needs to be installed with CocoaPods you could always follow the steps that I outlined in this SO answer to stop react-native link adding a dependency to the Podfile, it is not ideal but it is a workaround. Some dependencies require additions to be made to the Podfile, so you should only do this if the dependency doesn't require pods to run.
react-native link or react-native link dependency-name
Should you just use react-native link when linking any dependency or should you be more explicit and use react-native link dependency-name?
From my experience it is better to use react-native link dependency-name. This is due to the fact that react-native link will try to link (or re-link) all the dependencies that can be linked and this can lead to code duplication. Most of the issues that I have experienced have been when the Android native dependency is being linked. I think there has been some headway in stopping this from happening in subsequent updates, but the old adage applies here once bitten, twice shy
Linking good practice
When using react-native link dependency-name you should follow good practice so that you don't get stung. Sometimes dependencies that you try don't work as expected and removing all the code that was added during the linking process can be tricky. (Xcode project files can be a nightmare to go through if you are unfamiliar with them).
This is how I install dependencies and then link them.
Make sure that you are using version control, like git.
Make sure your code is fully committed with no unsaved changes.
Create a new branch, and check it out.
Install your dependency npm i dependency-name
Then link you dependency react-native link dependency-name
Perform any additional installation steps that the dependency requires. See the installation instructions for the dependency.
Check that your code works with the new dependency.
commmit changes and merge the branch.
Manual Linking
If you prefer to link your native dependencies manually then you should either follow the instructions on the dependency's website or you can look at the documentation that react-native provides.
Currently there is only an explanation on how to manually link iOS projects.
Manually linking Android requires you to make changes in the following locations:
settings.gradle
app/build.gradle
MainApplication.java
As always for the exact changes that you should make you should look at the dependency's manual linking instructions.
Do I have to link?
It depends on the dependency that you are using some dependencies use only code written in Javascript, so it is not required to link them, and there is no benefit served by running react-native link dependency-name.
However, if the dependency contains native code then you will have to link. Either manually or by using react-native link dependency-name.
How can I tell if I need to link the dependency?
Firstly you need to check the website, the github repo, or the npmjs.com page for the dependency. There will usually be instructions there telling you whether to link the dependency after you have installed it.
If you cannot find any instructions about linking, you (probably) won't need to link it.
If you are still unsure, check with the dependency maintainer.
Can I just run link anyway?
Yes, you can it won't do anything if there is nothing to link. But always run it with react-native link dependency-name to avoid issues.
When do I run link?
You only run it after you have installed your dependency. I would recommend running it just after you have installed the dependency. You should then check to make sure that it works, before installing any new dependencies so that you can easily debug.
You shouldn't need to run it more than once per dependency.
It doesn't matter how many components or changes to the javascript code that you make it won't affect the linking, as the linking is purely native and components are javascript.
What is autolink?
Autolink is a new feature that is being added to the react-native-cli. You can read more about autolink here.
Autolink replaces react-native-link
Autolinking is a mechanism built into CLI that allows adding a
dependency with native components for React Native to be as simple as:
yarn add react-native-webview
Autolinking is a replacement for react-native link that brings new features (such as ability to easily integrate native dependencies on iOS) and fixes some of the long-standing issues.
Once it is fully implemented it should make adding dependencies with native-code to your project much easier.
Linking native library means that you are going to integrate already implemented module into your application or module which completes your react native's module functionality.
Steps to integrate lib(android):
1) Add package name to new packages() 2) Add dependencies to settings.gradle file and main application's gradle i.e app/gradle file. 3) sync the projects gradle because you made changes in the gradle and it's done.
All manual steps like below you have to perform
1) Go to your project's home dir using cmd.
2) run npm install
3) Thereafter run rnpm link or react-native link
4) see ios folder in your project folder and if you find any pod file then run pod install after navigating into ios folder in cmd.
now instead,
1) Go to your project's home dir using cmd.
2) run npm install
3) Thereafter run rnpm link or react-native link
4) see ios folder in your project folder and if you find any pod file then run pod install after navigating into ios folder in cmd.
When you've installed a library with native content(android or ios) then you need to require linking to the component react-native library.
like this
react-native link react-native-sound-player
When you installed any third party library with native content,you have to link the dependencies in android and ios. react-native link is responsible for including the dependencies in gradlew and pod files.
for suppose you installed react-native-vector-icons package then you have to link in your gradlew files. the new version of react native 0.60 has auto linking.
npm install react-native-vector-icons
react-native link react-native-vector-icons
Thanks for asking this question
if you are working with fonts
react-native link is used for linking the fonts and assets to project
link command is also for linking the libraries to react-native
But now React-native too better so there is no need to link the library
we can use
pos install
npx jetify
it will automatically link the libraries
react-native link is an automatic way for installing native dependencies. It is an alternative to manually linking the dependency in your project. It works for both Android and iOS
I am asking this question for the third time and I don't get it why no one even tries to help on this, is this question not well explained? If you can ask for more information I can give!
I am having trouble created iOS folder inside my react native app(detached) as when I created the app I created it from windows machine and iOS folder didn't come when I wrote: exp detach
Now that I have got a macOS, how can I get to create iOS folder so I can use that to build from xCode. I tried react-native upgrade, this is telling me that I have some version conflicts, so I don't want to upgrade it actually, I just want to have iOS folder on my react native.
What would be the best solution in here?
Interestingly I tried exp detach over my detached app and it created iOS, it's working! hopefully this will help anyone!
Please follow the below steps:
Step I: Ensure below installable are installed
Java Sdk Android Studio
Xcode (in case of OSX)
HomeBrew (in case of OSX to install node)
Node/NPM (Node runs Javascript outside the browser. NPM is used for installing and managing Dependencies. Node and NPM come
together)
Those are some essential installs that you will need in your Project
**Step II: **
For windows/OSX you need to run the following commands in your command prompt/command line:
This is the important part for running a react native project:
**Step II: **
npm install -g react-native-cli
Then you can use this cli to start a new project like this:
**Step III: **
react-native init
Hope this helped you, please vote..
