Amplify-js: React Native - Unable to resolve “@aws-amplify/ui/dist/style.css”

I'm attempting to customize the AWS Amplify UI signin/signup process by following this article. Every time I import anything from aws-amplify-react I receive this error:

Unable to resolve "@aws-amplify/ui/dist/style.css" from "node_modules/aws-amplify-react/dist/Amplify-UI/Amplify-UI-Components-React.js"

I've tried installing @aws-amplify/ui specifically, along with other combinations of aws-amplify versions. Here's the relevant part of my package.json:

...
"aws-amplify": "^1.1.25",
"aws-amplify-react": "^2.3.5",
"aws-amplify-react-native": "^2.1.9",
...

And the versions of the specific UI & auth that I've tried:

"@aws-amplify/auth": "^1.2.21",
"@aws-amplify/ui": "^1.0.2",

Here is the import statement:

import { ConfirmSignIn, ConfirmSignUp, ForgotPassword, RequireNewPassword, SignIn, SignUp, VerifyContact, withAuthenticator } from 'aws-amplify-react';

Any help on resolving this issue is greatly appreciated.

Hi @dperconti, thanks for using AWS Amplify!

It looks like you are using both aws-amplify-react and aws-amplify-react-native. The aws-amplify-react module is not meant to be used with React Native. This is because CSS cannot be parsed in RN.

Please follow this guide to pass a theme object to the authenticator component to customize styling.

To use this with Expo, which allows Web and Android/iOS builds, I installed aws-amplify-react and aws-amplify-react-native and created two files:

//aws-amplify-react.js
export * from "aws-amplify-react-native";

//aws-amplify-react.web.js
export * from "aws-amplify-react";

With this setup I just have to do import ... from "./aws-amplify-react" and get the right implementation.

Now, I just have to hope they have the same interfaces, haha.

When I use aws-amplify-react and withAuthenticator in my react app. it throws the following error. Shouldn't it pick the CSS automatically? when I manually add the CSS path into my webpack css-loader, it works. However, when I build my app in the AWS Codebuild it throws the same error again. Please help.

The same for me.

To be clear, there is an issue with importing .css files that's being addressed, but when using React Native, use aws-amplify-react-native, _not_ aws-amplify-react due to implementation differences.

Resolving issue as this is solved in version 3 of Amplify. Please review what @ericclemmons statement is above and please let us know if you are still experiencing this issue. Thanks!
