##Vue 3 Migration Guide : List of Mistakes to Watch Out For


####1.Neglecting to Update Dependencies

One of the primary reasons for migrating to Vue 3 is to take benefits of its new features and optimizations. However, these benefits might not be fully realized if your project's dependencies, such as Vue Router and Vuex, are not updated as well. Many a times developers do a mistake of neglecting to update these dependencies which can lead to compatibility issues and unexpected behavior.

**Solution:** Before beginning the migration, ensure that all third-party dependencies are compatible with Vue 3. Check their documentation for guidance on version compatibility or updates required for Vue 3 support. Additionally, updating Vue Router and Vuex to their Vue 3 versions is crucial for a smooth migration.

####2.Overlooking the Composition API 

Vue 3 has introduced the Composition API, which provides a more flexible and modular way of organizing and reusing logic within components. Failing to understand and leverage the Composition API can result in code that is not taking full advantage of Vue 3's capabilities.

**Solution:** Take out time in understanding the Composition API and how it differs from the Options API. This paradigm shift allows for better separation of concerns and improved code reusability. Refactor your components to use the Composition API, especially when migrating, to optimize your codebase.

####3.Underestimating the Reactivity System Changes

Vue 3's reactivity system has done significant improvements with a purpose of offering better performance and predictability. However, assuming that Vue 3's reactivity system works exactly like Vue 2's can lead to unexpected behaviors and debugging challenges.

**Solution:** Study Vue 3's new reactivity system thoroughly. Familiarize yourself with the changes and enhancements, such as the ref and reactive functions, to ensure a seamless migration. Update your codebase to leverage these new features for improved performance and maintainability.

####4.Not Addressing Deprecated Features

Vue 3 comes with deprecated features and options from Vue 2, which might not be available in subsequent versions. Failing to identify and replace these deprecated features can result in broken functionality or hindered performance.

**Solution:** It is advisable to Consult the official Vue 3 documentation for a comprehensive list of deprecated features and their recommended alternatives. Audit your codebase and replace deprecated features with their Vue 3 equivalents to ensure your application remains functional and maintainable.

##Wrap Up
