Error: Reanimated 2 Failed To Create A Worklet, Maybe You Forgot To Add Reanimated’s Babel Plugin?

Understanding the Error: “Reanimated 2 Failed to Create a Worklet”

If you are someone who has been working with React Native, you must have come across the Reanimated library. In simple terms, Reanimated is a React Native library which enables users to create fluid and responsive user interfaces. It comes with a lot of features that are not present in the vanilla React Native.

However, while working with Reanimated, you might encounter an error that says “Reanimated 2 Failed to Create a Worklet”. This error occurs when the Reanimated library is not able to generate a Worklet.

In technical terms, a Worklet is a piece of code that runs natively on the UI thread and is used to calculate the values of animated variables. In simpler terms, it can be considered as a function that is executed natively.

Now, coming back to the error, it generally occurs if you forget to add the Reanimated Babel plugin. The Reanimated Babel plugin is required by the library to function properly.

To resolve this error, you need to make sure that the Reanimated Babel plugin has been added to your project. If it is already installed, try running the following command:

npm run clean && npm run start

This should help you fix the error and your project should start working as intended. In case the error persists, you can refer to the React Native documentation or seek help from the developer community to resolve the issue.
