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 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 am creating a stencil project which uses an npm package inside it, is there any options to add an npm package inside stencil project. Any suggestions I searching for a solution for quite a while.
This is how i use ck-editor in angular
<ck-editor name="editor" #myEditor [(ngModel)]="templateSetValue.template_content"
(change)="handleEditorData($event)">
</ck-editor>
Is it possible to use the same is stencil project
https://www.npmjs.com/package/ngx-ckeditor
Not sure if I understood the question correctly, but to add a package from npm in your Stencil.js project, you can just install it, like you would in any other node project:
npm install <some-package>
For example nprogress:
npm install nprogress #types/nprogress
and then import it in your code like
import nprogress from 'nprogress';
nprogress.start();
// ...
I am developing a button ui package for react native. I try to build an example project to test this button. The directory structure is as follows:
my-button/
package.json
index.js
example/
package.json
index.js
I try to use npm link:
cd my-button
npm link
cd example
npm link my-button
In example/node_modules/ I can see my-button symlink, VSCode also can auto complete function in my-button package.
But execute example app will show error:
Unable to resolve module my-button ...
Module does not exist in the module map or in these directories: ...
But the path in the error message is correct.
Don't know where I was wrong, or in React-Native have any special way to deal with link local dependency?
I also tried npm install file:../.. It works fine in this way, but not easy to update dependency in example/ after I edited my-button.
The npm link command doesn't work because React Native packager doesn't support symlinks.
After a little research, I discovered that there are two ways to go about it.
Use haul packager in the example app. Haul supports symlinks, so you can use npm link as usual.
Use local dependency via file:../ and then edit files in node_modules folder or reinstall every time you make changes.
I found Haul to work great for this use-case and even set-up a little starter project that also includes storybook, which is really helpful if you have many components to switch between.
Try wml (https://github.com/wix/wml)
It's an alternative to npm link that actually copies changed files from source to destination folders
# add the link to wml using `wml add <src> <dest>`
wml add ~/my-package ~/main-project/node_modules/my-package
# start watching all links added
wml start
I couldn't always make it work with yarn link. What i found extra useful is yalc:
First install it globally once forever:
npm install -g yalc
In the local library/package (i'll call it my-local-package), and run:
yalc publish
Then in your project which uses my-local-package as a dependency, run:
(if you already have added it with any other way, first uninstall it (npm uninstall -S my-lockal-package)
yalc add my-local-package
npm install
If my-local-package is a native module, then run react-native run-android to link the dependency. (or run-ios)
If you make any change in the my-lockal-package, then:
cd path/of/my-local-package
yalc push //updates the local package
cd path/to/my-project
npm install
react-native run-android (or run-ios)
In case the update hasn't been applied, try to cd android && ./gradlew clean && cd .. and then rerun: react-native run-android.
I'm having the same issue while developing a native module wrapper around an existing native SDK. At first I followed #aayush-shrestha's suggestion to install the package locally. Like this:
npm install ../<package-folder> --save
This works as long as I reference the module via NativeModules. Import it:
import { NativeModules } from 'react-native';
And then access a module called ActualModuleName like this:
NativeModules.ActualModuleName
But it fails when I attempt to import the module by name:
import { ActualModuleName } from 'react-native-actualmodulename'
To make that work I had to first pack the package. Run this in the package's root directory:
npm pack
This generates a gzipped tarball:
react-native-actualmodulename-1.0.0.tgz
Now install that in your app:
npm install <path/to>/react-native-actualmodulename-1.0.0.tgz
An enormous downside to this is that you have to re-pack the package every time you make a change to the module. The only workaround I know of is to modify the package's files in node_modules directly and then copy those changes back to your repo when you're done.
But the upside is that your app's source can import ActualModuleName the same way you'll import it once it's released via npm; no environment-specific code necessary.
You can use npm link using Metro. Just add the source folder of the linked package to watchFolders in your metro.config.js.
Ran into the same problem. While I could not make npm link work as it should, I worked around it by installing the local package in the project folder
npm install ../<package-folder> --save
This will install the package like a regular package but from the local folder.
The downside is that the changes you make on the package will not be reflected. You will have to npm install after every change.
Change your package.json
//...
"dependencies": {
//...
"my-button" : "file:../"
},
//...
I also came across this problem. After visiting the below link, I came to know that react- native does not support symlinks.[Click here][1]
However, I have solved this by adding these lines in the metro.config.js file. Please replace your_module_name with your module name.
const path = require('path');
const thirdPartyPath = path.resolve(__dirname + '/../your_module_name/'); // Path of your local module
const thirdParty= {
'your_module_name': thirdPartyPath,
};
const watchFolders = [ thirdPartyPath];
module.exports = {
// existing dependencies
resolver: {
thirdParty,
},
watchFolders
};
I ran into the same problem.
I tried to install a local module using npm, and kept running into the issue of not being able to resolve the module, even though I could see the folder in node_modules and autocomplete of class and method names worked.
I was able to bypass it by installing the local library using yarn instead of npm after seeing this open issue on github. Issue was opened September 2020 and no comment from Facebook as of yet.
This work for me:
step 1 go to package:
npm link packageNameHere
This will link this package to global node_module
step 2 go to directory which you want to use this package and run these
npm link pathToPackageDirectory
npm install pathToPackageDirectory
ex: npm link ~/myDemoPackage
This will link global node_moudle to this project
If you want to import package to file, USE FILE PATH INSTEAD OF PACKAGE NAME !
ex:
my package name is stripe-api-helper. my code are in src/index.ts
then I need to resolve like this:
import { postStripe, Item } from '#aliciaForDemo/stripe-api-helper/src'
if u use '#aliciaForDemo/stripe-api-helper' it will fail.
Could never get my own environment working using any other suggestions, but found a hack that works well (though not ideal) that can be easily set up in just a few lines of code and without changing your RN project configuration.
Use fs.watch for changes recursively in the directory where you're working on your library, and copy the updates over whenever there's been a change:
import fs from 'fs'
const srcDir = `./your-library-directory`
const destDir = `../your-destination-directory`
fs.watch("./src/", {recursive: true}, () => {
console.log('copying...')
fs.cp(srcDir, destDir, { overwrite: true, recursive: true }, function() {
console.log('copied')
})
})
For those still looking for a simple solution without other dependency, try this:
yarn --version
1.21.1
npm --version
6.13.4
Install in project root
cd my-button
yarn install or npm install
register linking in my-button
yarn link or npm link
Install example project
cd example
yarn add ../ or npm add ../
link to my-button
yarn link my-button or npm link my-button
complete pod installation (if necessary)
cd ios
pod install
Try to run
npm run watch
inside the button package. Currently, I'm using this to apply changes from the library to my main project. Please let me know if it works!
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'
