Import Session not working - javascript

In my Ember App I want to extend Ember Simple Auth's Session Object (I'm using the Ember CLI Addon). That's why I import it like stated in the docs:
import Session from 'simple-auth/session';
When I try to build my app the console logs a file not found error.
I can import the LoginControllerMixin with:
import LoginControllerMixin from 'simple-auth/mixins/login-controller-mixin';
Is anyone else experiencing this problem or got a clue what could cause this issue?

That's a known bug in the Ember Simple Auth Addon (https://github.com/simplabs/ember-cli-simple-auth/issues/1) - for now please install the addon directly from the github repository.

Usage of Firestore in React doesn't work - Module not found

it's very likely that I've done an obvious mistake but I can't find it, even after many hours of research.
Let me tell briefly you what I've done:
npm install firebase --save
import firebase from "firebase";
firebase.initializeApp({ ... });
After compiling the following error message is shown:
Module not found: Can't resolve 'firebase' in '/Users/luisgaspar/Desktop/Coding/React-Learning/chat-app-1/src'
Do you have suggestions on where my mistake could be?
its actually due to the new upgraded version of firebase to 9.0.1 . You can find the official documentations here : https://firebase.google.com/docs/web/modular-upgrade .
Also if you wish to use the previous commands as in version 9, you should try like below :
import firebase from 'firebase/compat/app';

Attempted import errors in react-native-web monorepo architecture

Hi there,
I am following this article to setup a react-native + web code sharing. Here is the repo link with bare-bone monorepo setup as described in above article.
I successfully did setup bare-bone monorepo app as described in above article, than i ported my existing react-native app code to this architecture(in the components folder) and got mobile app working and everything.
I am getting some errors when i try to run web app(which used react-native-web to convert react-native to web). Its not that i was not expecting some errors, i know react-native-web is yet not that stable and not that up to date for react-native version above 0.55 and all those gotchas.
But the errors i am getting here are more related to my webpack config i think. My config-override.js file is basically the same as original one except this part(which i changed in a hope to get through the errors i will mention below):
const appIncludes = [
resolveApp('src'),
resolveApp('../components/src'),
resolveApp('../../node_modules/react-navigation-deprecated-tab-navigator'),
resolveApp('../../node_modules/react-native-color-matrix-image-filters'),
resolveApp('../../node_modules/react-native-htmlview'),
resolveApp('../../node_modules/react-native-loading-spinner-overlay'),
resolveApp('../../node_modules/#react-native-community/async-storage'),
resolveApp('../../node_modules/react-native-cookies'),
resolveApp('../../node_modules/react-native-router-flux'),
resolveApp('../../node_modules/react-native-actionsheet'),
resolveApp('../../node_modules/react-native-autocomplete-input'),
resolveApp('../../node_modules/react-native-circular-progress'),
resolveApp('../../node_modules/react-native-google-places-autocomplete'),
resolveApp('../../node_modules/react-native-image-progress'),
resolveApp('../../node_modules/react-native-image-zoom-viewer'),
resolveApp('../../node_modules/react-native-image-pan-zoom'),
resolveApp('../../node_modules/react-native-keyboard-aware-scroll-view'),
resolveApp('../../node_modules/react-native-linear-gradient'),
resolveApp('../../node_modules/react-native-permissions'),
resolveApp('../../node_modules/react-native-phone-input'),
resolveApp('../../node_modules/react-native-picker-select'),
resolveApp('../../node_modules/react-native-progress'),
resolveApp('../../node_modules/react-native-push-notification'),
resolveApp('../../node_modules/react-native-snap-carousel'),
resolveApp('../../node_modules/react-native-svg'),
resolveApp('../../node_modules/react-native-tab-view'),
resolveApp('../../node_modules/react-navigation-drawer'),
resolveApp('../../node_modules/react-navigation-stack'),
resolveApp('../../node_modules/react-native-screens'),
resolveApp('../../node_modules/react-navigation-tabs'),
resolveApp('../../node_modules/#react-navigation'),
resolveApp('../../node_modules/react-native-router-flux'),
resolveApp('../../node_modules/react-native-gesture-handler'),
resolveApp('../../node_modules/react-navigation'),
]
Couple or errors i am getting on yarn workspace web start are:
import {
Grayscale
} from 'react-native-color-matrix-image-filters';
It gives:
Attempted import error: 'Grayscale' is not exported from
'react-native-color-matrix-image-filters'.
If i just remove this import and its use, i than get:
Attempted import error: 'react-native-cookies' does not contain a
default export (imported as 'CookieManager').
On:
import CookieManager from 'react-native-cookies';
While playing around, i also got:
...../node_modules/react-native-router-flux/src/navigationStore.js
Attempted import error: 'TabBarBottom' is not exported from 'react-navigation-deprecated-tab-navigator' (imported as 'DEPRECATED_TabBarBottom').
I am pretty sure this is something wrong with my webpack/babel config(config-override.js file). And i certainly know i will get more errors after resolving these. And this setup might end up not working at all for us. But it worths a try and i must be able to get through these errors with your help.
Thanks.
You can probably not use these packages on the web since they're react native packages (Android and iOS) and not web packages.
Which means that you have to split the files that import and use these packages.
Example of creating a wrapper for CookieManager: cookieManagerWrapper.js(everything else: Android and iOS) and cookieManagerWrapper.web.js(Web only).
In the web specific js file, you don't import CookieManager but import an alternative web library instead to implement the same functionality as on mobile but with different code that works on the web.
Then you can import and use cookieManagerWrapper.js everywhere and react-native-web will automatically substitute it with the cookieManagerWrapper.web.js when available.
Some react native packages do work on web too when they're only consisting of platform independent JavaScript code. Also some packages have web implementations that can be aliased in webpack like react-native-gradients with react-native-web-gradients, sadly this is not the case with the packages mentioned in the question.
This file splitting with file.js, file.web.js, file.android.js and file.ios.js makes it possible to write different implementations for each platform. This is also great for some user interface code, you can use 3rd party react components on the web and 3rd party react native components on mobile that look similar to implement more complex user interactions since react native web supports all regular react code and jsx tags on the web.
I was able to get past this error by adding:
config.module.strictExportPresence = false in the config-override.js
Now i am stuck on further issues.
Original issue in the question is gone by this. I will post with any other related updates if i have any.

Unable to compile react application as it says "Module not found"

I have been trying to execute a very simple react application, but for some reason I'm unable to compile it. When i try to compile it in bash using "npm start", i get the error stating "Failed to compile: ./src/index.js
Module not found: Can't resolve './registerServiceWorker' in '/Users/Pruthvi/Desktop/ReactApplication/my-app/src'"
can anybody help me as I am a new bee to react application!
By default, create-react-app will create a progressive web app, as documented here. The progressive web app relies on registerServiceWorker() in the registerServiceWorker.js file. You have apparently deleted this file, so your project no longer builds.
You have two choices:
Keep your project as a progressive web app, in which case you should simply restore the original state you had after first creating.
Opt out of the progressive web app features.
In order to opt out of the progressive web app features, you need to modify your src/index.js file as follows:
Delete the import of the registerServiceWorker.
Delete the registerServiceWorker() call.
Your src/index.js will then look like this:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
// Deleted -- import registerServiceWorker from './registerServiceWorker';
ReactDOM.render(<App />, document.getElementById('root'));
// Deleted -- registerServiceWorker();
Once you've made those modifications to your index.js, you can safely delete the registerServiceWorker.js file (which it appears you've already done based on the error message you've posted).
The documentation gives a more complete description of how to opt out and some of the consequences of having a progressive web app.
If you are new to react and need to build apps fast you can try
create-react-app by facebook
it a command line tool that will help you build better react app fast with zero configuration you can learn more from the link above and its easy to use
also make sure that you use a good editor that can help you catch errors
and to help you and give you good answer the second time please provide your code to understand the problem well .

React: How to load components properly?

I am working on a simple app in react with ES6 and babel. Recently I faced this issue. I used react-notifications package here: https://github.com/minhtranite/react-notifications
I just followed the docs and it works fine. I can import it with import {NotificationContainer, NotificationManager} from 'react-notifications';
But then I tried to work with this: https://github.com/cezary/react-loading
Now in the example of react-loading, the developer isn't using the ES6 way to get the component. I tried to look at the JS file and tried this after doing npm install react-loading:
import {Loading} from 'react-loading'; but somehow this doesn't work. I get this:
You likely forgot to export your component from the file it's defined in
But I can see it is exported. What am I doing wrong?
Since it is a single module, it is exported as default. You'll have to do this:
import Loading from 'react-loading';

How to import poorly named libraries?

Background
I am using a library called baguettebox.js
You can see it here
Problem
When I import this into my project like
import * as BaguetteBox from 'baguettebox.js';
I get a warning flagged inside my IDE PhpStorm
Cannot resolve file 'baguettebox.js'
This is because the folder & package.json are called baguettebox.js.
The Package is actually found and works in my application, I just want a good way to handle this error.
It's the IDE issue. Please follow WEB-25805 for updates
