working on implementing magic.link using react-native but i get an error when importing Magic
import { Magic } from "#magic-sdk/react-native";
error:
Attempted import error: 'WebView' is not exported from 'react-native'.
I think its because of the sub dependency of react-native-webview has been removed, but i did install it. npm install --save react-native-webview#^8.0.0 as the tutorial says? Stuck for a while now, not sure how to procede with Magic
https://magic.link/docs/login-methods/email/integration/react-native
This link was attached to the docs https://github.com/react-native-webview/react-native-webview/issues/373 . But don't know why it should not work, since the correct react-native-webview dependency was installed (8.0.0) or (^8.0.0, which is 8.2.1)
I installed the packages as the tutorial suggests
yarn add #magic-sdk/react-native
# Ensure the required `peerDependencies` are installed
yarn add react-native-webview#^8.0.0
Use this one:
npm install --save #magic-sdk/react-native
then try to link it using npm react-native link

I did not find any relevant documentation regarding how to use the npm package of antmedia.
I install it by doing a yarn add #ant-media/webrtc_adaptor.
When i try to import it
import { WebRTCAdaptor } from '#antmedia/webrtc_adaptor';
Which results in this error
I realized that in package.json, it is the index.html that is in main
Is there a documentation about it ? I am currently not using React Native
Note: yarn add #ant-media/webrtc_adaptor#1.2.0 is definitly not working
I am using https://reactnative.dev/docs/environment-setup 0.64
I npm install #walletconnect/client
put below import in App.js
import WalletConnect from "#walletconnect/client";
after npx react-native run-ios and got below error:
error: Error: While trying to resolve module `crypto` from file `/Users/hahaha/workspace/mobile/reactnative/nonft/node_modules/#pedrouid/iso-crypto/dist/cjs/helpers/env/node.js`, the package `/Users/hahaha/workspace/mobile/reactnative/nonft/node_modules/crypto/package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`/Users/hahaha/workspace/mobile/reactnative/nonft/node_modules/crypto/index.js`. Indeed, none of these files exist:
I tried to remove node_modules folder and npm install again but still get the same error.
I am sure that it is thrown by #walletconnect/client because when I removed
import WalletConnect from "#walletconnect/client";
then the error gone
crypto is a built in Node module, which isn't available in React Native, as iOS/Android apps don't run with a Node runtime - only web apps do.
There are a few ways to solve this problem, all of them fairly hacky.
One way is to replace the crypto module with a React Native native module that does the same thing. React-native-crypto is the package used by create-react-native-dapp (https://www.npmjs.com/package/create-react-native-dapp) to integrate with WalletConnect: https://www.npmjs.com/package/react-native-crypto
To get this integration working, note that you'll need to be able to link modules and run rn-nodeify, as it mentions in the instructions on that npm package:
npm i --save react-native-crypto
# install peer deps
npm i --save react-native-randombytes
react-native link react-native-randombytes
# install latest rn-nodeify
npm i --save-dev tradle/rn-nodeify
# install node core shims and recursively hack package.json files
# in ./node_modules to add/update the "browser"/"react-native" field with relevant mappings
./node_modules/.bin/rn-nodeify --hack --install
If you're using Expo, note that you'll need to eject Expo before this can work.
Another hacky workaround is to run WalletConnect in a WebView using react-native-webview. There's an old but working example of this that you can just use to plug and play WalletConnect without requiring linking that you can get here: https://github.com/cawfree/react-native-walletconnect
Note that that repo is archived and effectively hardcoded to WalletConnect version 1.0.0, but it's a pretty simple codebase - you can just effectively copy and paste its code and update it to the latest version of WalletConnect to get it working with a later version if desired.
As a final note, there are multiple ways to get node modules running in React Native on top of rn-nodeify. If you'd like to explore other methods of getting node modules running, here's a quick rundown of other possibilities: https://gist.github.com/parshap/e3063d9bf6058041b34b26b7166fd6bd
I have posted this here have created react-native app using
react-native init myapp
added web3 in package.json
npm install
react-native run-ios
but i am getting the error unable to resolve module crypto from web3-eth-accounts. Is there any way to fix this
unable to resolve crypto
Crypto is a node js module, when React Native is run - it uses Javascript Core. Crypto isn't include within this. When I installed crypto I used the following package:
https://www.npmjs.com/package/react-native-crypto
Instructions:
npm i --save react-native-crypto
# install peer deps
npm i --save react-native-randombytes
react-native link react-native-randombytes
# install latest rn-nodeify
npm i --save-dev tradle/rn-nodeify
# install node core shims and recursively hack package.json files
# in ./node_modules to add/update the "browser"/"react-native" field with relevant mappings
./node_modules/.bin/rn-nodeify --hack --install
rn-nodeify will create a shim.js in the project root directory
// index.ios.js or index.android.js
// make sure you use `import` and not require!
import './shim.js'
// ...the rest of your code
Import shim.js in your index.js file.
When you have done that crypto should be made available, if it still doesn't work I had to create a const in my App.js file like so:
export const cryp = require('crypto');
And import it into the components you need.
UPDATE
I've done a fresh build for this, I followed the below:
react-native init TestApp
Follow the instructions above for Crypto.
Linked:
react-native link
react-native run-ios
react-native-crypto don't work on recent react-native version 0.63.3 and react version 16.13.1, any more.
I used crypto-js package. The version is 3.1.9-1 in my react-native app. It's working well.
You can add below line in package.json file.
"crypto-js": "3.1.9-1",
crypto is a node's library that works with the browser however we can use it with react native with some hacks mentioned below follow these steps and boom! you are ready to rock.
npm i --save react-native-crypto
==> install peer deps
npm i --save react-native-randombytes
react-native link react-native-randombytes
==>install latest rn-nodeify
npm i --save-dev tradle/rn-nodeify
==> install node core shims and recursively hack package.json files
==> in ./node_modules to add/update the "browser"/"react-native" fieldwith relevant mappings
./node_modules/.bin/rn-nodeify --hack --install
i had the same problem, it seems the crypto module is not supported by react native because when i install crytpo , it does not have an index.js file in the node_modules. so my problem came about when i was trying to use jsonwebtoken which uses crypto to encrypt data. so i uninstalled jsonwebtoken and switched to react-native-pure-jwt
I ran:
react-native install react-native-in-app-utils
and it completed successfully. I added the import to my code:
import { NativeModules } from 'react-native'
const { InAppUtils } = NativeModules
No errors occur in building and starting but NativeModules is empty and InAppUtils is undefined.
I have used this successfully in RN 0.48; this is on RN 0.55.
Is there some step I am missing?
Documentation details for react-native-in-app-utils is misleading regarding Linking.
Install Library (react-native-in-app-utils) using rnpm. you need to install rnpm.
1.npm install rnpm -g
2. rnpm install react-native-in-app-utils
rnpm will auto link your library for IOS.
SUGGESTION
Do not install library using Yarn , npm and react-native install react-native-in-app-utils
react-native-in-app-utils requires you to have created your app with 'react-native init`. Or, you have to eject from CRNA.
CRNA can't use native modules unless you eject/detach (similar to expo, as they're interrelated):

I´m having a issue on android. Got this error:
undefined is not a function(evaluating '_iterator2typeof
Symbol==='function'?Symbol.iterator:'##iterator'´)
I think it is related to the use of for of, es6.
Can i add babel-polyfill to React Native Project ?
In order to add babel-polyfill to your react-native project after installing
npm install --save babel-polyfill
just import it like this in your entry endpoint:
import 'babel-polyfill';
Now you can use new built-ins like Promise or WeakMap, static methods like Array.from and instance methods like Array.prototype.includes, etc.
You can use
npm install es6-symbol --save
Then add in your index.android.js & index.ios.js
import 'es6-symbol/implement'
