I am trying to implement Google Authentication into my Expo/react native component based class, but the example Expo gives is for functional components.

They use this code for the Google Authentication:

I have recently upgraded my app from SDK 40 to SDK 44 and came across this error App.js: [BABEL]: Unexpected token '.' (While processing: /Users/user/path/to/project/node_modules/babel-preset-expo/index.js)

Error Stack Trace:

I'm very new and trying to set Firebase Google authentication in Expo RN app,

Expo docs code snippet below:

https://docs.expo.dev/guides/authentication/#google

I was developing a chat app in practice using react-native expo, but when I suddenly executed "expo start" in the usual development flow, the error "could not connect to development server" was displayed.

If you have experienced the same error and know a solution, I would appreciate it if you could help.

Since I was linking with aws-amplify just before, I thought that the one installed due to that relationship was the cause of the error, but since the application starts normally in the browser, only the iOS simulator does not work (Android is in a situation where it downloads endlessly and does not start)

What I tried

1)Delete the cache with expo start -c

2)As the error says, npm start and then reload is repeated.

3)Delete 19000 with the kill command, thinking that it is a port problem. ・ Npm install ・ Rm -rf node_modules / && rm -rf yarn_lock / && yarn install && cd ios && pod install

Nothing worked, I cannot come up with any good idea to solve it. All solutions from the research are failed. What else could I do?

Can't for the life of me figure out why my app suddenly won't start. I keep getting this error:

Unable to resolve module fs from node_modules\firebase-admin\lib\firebase-namespace.js: fs could not be found within the project. If you are sure the module exists, try these steps:

1. Clear watchman watches: watchman watch-del-all
2. Delete node_modules and run yarn install
3. Reset Metro's cache: yarn start --reset-cache
4. Remove the cache: rm -rf /tmp/metro-*

whenever I run expo start in the root folder. I've even tried expo start -c to reset the cache.

I've also tried removing node_modules and npm installing it back for both the {myapp}/functions/node_modules and {myapp}/node_modules.

I've tried updating firebase-admin and all dependencies.

It's weird because my app was working a couple days ago and this came out of the blue. I've never had to install fs before.

Anyone got any idea what's going on here? It feels like a simple environment fix, but I'm not sure.

My app dependencies if it helps:

I'd like to ask about the following error. So I've been developing a small BLE app a year ago and successfully managed to implement it. I did not push it to the Google Play store but instead installed it somehow on the Android via usb.

However, now I need to get it back up and running but am facing a plethora of errors.

Context : React Native Expo SDK41 Bare Workflow (ejected) Android Build

After ejecting, and going to build time (EAS Build) i got those two remaining errors : Those are blocking and very annoying. I tried : -Defining the function getMainComponentName to return my main component name string -Removing One and both overrides -Removing getMainComponentName and putting in place my main component name string

Im stuck

I am creating a React Native mobile application for a school project and I want a user to be able to login to Spotify to be able to get information about their playback using the Spotify API.

I am developing for iOS and using Expo, so have found this documentation from Expo to be quite helpful. Using their sample Auth Code, I was successfully able to make a very simple React app that allows the user to push a button that prompts them to login with Spotify. For my project, though, I have different components corresponding to different screens in my app. Whenever I try to move the code into a component, I get an error that I am unsure how to resolve (I am still pretty new to React and Javascript).

Here is the code:

upgraded Expo SDK along with referring to the “Deprecations, renamings, and removals” section of the SDK 40 upgrading post from SDK39 to SDK40 and got an error.
