If the code you're adding in each "piece" is complex, you may want to simplify what you're doing.Apply your recent changes piece by piece, until it breaks.Revert back to a working version of your code (this may even be a completely blank npx create-expo-app project).This step is vital in fixing obscure errors. Isolate the code that's throwing the error.Search for the error message in Google and Stack Overflow, it's likely you're not the first person to ever run into this.For errors that aren't as intuitive to solve, here's a good list of steps to take: Sometimes you'll be able to tell exactly what's wrong just by the stack trace, but other times the error message is a little more cryptic.

Let's go through some of our recommended practices when it comes to each of these situations, and at the end of this guide, we'll recommend tools that can make debugging easier. Errors you (or your users) encounter in production.Errors you encounter in the development.It's useful to split errors into two categories: Whether you're developing your app locally, sending it out to select beta testers, or launching your app live to the app stores, you'll always find yourself debugging issues. Learn about different techniques and tools available to debug your Expo project.
