🚀 Starting with Jest Tests in Next.js and Encountering an Error Right Away! 🚀

I encountered an initial error:

[Error] Parsing error: Cannot find module 'next/babel'

Let’s look into how to fix this. The first solution I found was this:

Create a .babelrc file in the project root and add the following code:

{
  "presets": ["next/babel"],
  "plugins": []
}

Next, open the .eslintrc.json file in the root directory. It probably looks like this:

{
  "extends": ["next/core-web-vitals"]
}

You need to add next/babel to this part:

{
  "extends": ["next/babel", "next/core-web-vitals"]
}

Does that solve the problem? Yes, but…

In reality, you don’t need to add .babelrc. Just adding next/babel to .eslintrc.json resolves the issue.

If it still doesn’t work, consider adding .babelrc as well.

A common issue arises when your device's iOS version is too new for the Xcode version you're using. This often manifests as an "incompatible build number" error, and looks like this: DVTDeviceOperation: Encountered a build number "" that is incompatible with DVTBuildVersion. This usually happens when you are testing with beta versions of either iOS or Xcode, and can prevent Xcode from properly compiling your storyboards. Let's explore why this occurs and what you can do to resolve it. Why This Error Occurs The core problem lies in the mismatch between the iOS version on your test device and the Software Development Kit (SDK) supported by your Xcode installation. Xcode uses the SDK to understand how to build and run apps for specific iOS versions. When your device runs a newer iOS version than Xcode anticipates, Xcode mi...

How to Fix the “Invariant Violation: TurboModuleRegistry.getEnforcing(…): ‘RNCWebView’ Could Not Be Found” Error in React Native

When working with React Native, especially when integrating additional libraries like react-native-signature-canvas , encountering errors can be frustrating. One such error is: Invariant Violation: TurboModuleRegistry. getEnforcing (...): 'RNCWebView' could not be found This error often occurs when the necessary dependencies for a module are not properly linked or when the environment you’re using doesn’t support the required native modules. Here’s a breakdown of how I encountered and resolved this issue. The Problem I was working on a React Native project where I needed to add the react-native-signature-canvas library to capture user signatures. The installation process seemed straightforward: Installed the package: npm install react-native-signature- canvas 2. Since react-native-signature-canvas depends on react-native-webview , I also installed the WebView package: npm install react- native -webview 3. I navigated to the iOS directory and ran: cd ios pod install Everythi...
