Understanding the Hydration Error

When you see the message: "Hydration failed because the initial UI does not match what was rendered on the server," it indicates that your application has detected a difference between the content delivered from the server and the content generated on the client. This discrepancy often leads to unexpected behavior in your application. The goal is to ensure that both the server and client render the same UI.

Common Causes of Hydration Errors

Missing Elements: Elements that are rendered in the client but not in the server or vice versa.

Conditional Rendering: Using different conditions for rendering elements on the server and the client.

State Initialization: React hooks or state that produce different outputs during the first render on the client and server.

Example of a Common Issue

Let's say you have the following React component that is responsible for displaying a list of coins:

Identifying and Fixing the Problem

Correcting the Code

To resolve the hydration error, you just need to wrap your row elements within a <tbody> tag. Here’s the revised code:

Why This Works

The <tbody> element is an important part of the table structure in HTML. When you include it, it informs both the server and client how to structure the table properly, ensuring they render the same content. This simple addition can help eliminate hydration errors that are cauused by structural mismatches.

Conclusion

By following best practices and keeping a keen eye on your rendering methodology, you can overcome these challenges quickly and effectively. Happy coding!
