QUESTION

Webpack compilation failed in react-native-web on {Node} i.e. Flow Syntax saying "You may need an appropriate loader to handle this file type"

Asked 2021-Jun-12 at 15:49

I am new to node/npm, react and react-native so very new to react-native-web as well. It's been 3 days for me to integrate react-native-web in a Hello World App generated using npx react-native init as per the doc. I tried using both templates: with and without typescript, but no success so far. The farthest I got is to run the app code written in index.web.js but if I add any component from ./src/components/ then I get errors, mostly of webpack.

I created a test repo for easy regeneration of error, So Steps to reproduce are as below:

Download this repo in your system.
npm install
npm run web

Now you'll see the error in the terminal.

Versions:

metro-react-native-babel-preset: 0.66.0
node: 16.3.0
npm: 7.8.0
OS: Windows 10 - 64 bit

I followed official documentation but with webpack@^4 and referred this article and somehow managed to reach the below situation:

Webpage is getting rendered if my whole code is inside index.web.js.
But when I import App inside this then I get compilation failed due to loader error.

Working index.web.js:

Finally, It's been resolved, my Hello World is done.

These 2 replies from the maintainer himself (@necolas) on this discussion helped me to get the issue.

Reply 1 by @necolas This line in the stack trace is telling you that you're trying to bundle RN internal code in your web bundle: node_modules/react-native/Libraries/NewAppScreen/index.js.

First, you should not be loading any of the RN package on web, especially not parts that aren't part of the public API . Second, as mentioned in the inline comments of the config you pasted above, you need to explicitly list everything in node_modules that needs compiling.

QUESTION

Build is failing for older projects for React-Native iOS XCode Version 12.5

Asked 2021-Jun-11 at 17:21

It is very new to me see this problem which started happening recently. Previously my app used to work fine on the iOS simulator by running this command react-native run-ios. Now I have done a lot of research and made my app run via XCode. But somehow the metro bundler is not linked when the app runs via XCode.

I tried running the app via react-native run-ios and every time I am seeing this error. It is too big to copy paste every error here, but here are some of them:

I am guessing all third party Pods will need to update their RN Pod Specs to use XCFrameworks. That's what I just did and it seems to work ok.

This means that you, as an RN package user, you will either need to wait for the package authors to update their podspecs to use XCFrameworks or add a build config that excludes the 'arm64' arch (but then will not work on M1 macs).

Alternatively, you can visit the node_modules//thrid-party.podspec and update it yourself. But that means you will need to build the XCFrameworks yourself too. So.....

I figured out that it's most likely babel issue. If you faced this issue like I had, upgrading libraries, just rollback to the older version that works, and upgrade libraries one by one. I reproduced this issue after I upgraded @babel/core. I just rolled back again and never touched babel again. Still works fine.

Well, I performed some experiments loading assets, it looks like there is a problem with the bundler when using require inline, e.g., using the image component like this fires the same error

Try requiring your asset in a previous line and then pass it to the .fromModule call.

I'm working on the react-native storybook project and I'm trying to re-use some code that is used to load files (stories) into the application. On the web version of the app this code is used to keep track of the previous list of story files (previousexports) so that when you reload it doesn't duplicate the stories.

I had a discussion with a colleague since asking this question here which lead me to believe that the data param is not supported.

Also looking into the metro code (metro bundler for react native) appears to confirm this.

If you look at the require polyfill in the metro repository you can see the following type definitions.

I guess you are trying to use firebase as a signalling medium and want to use react-native-webrtc for the video calling.

Here is the sample code I have for the same solution with the latest libraries and react-native version.

Just set up ios and android using this above link and then use the below code for reference.
