Error message
Error: Hydration failed because the initial UI does not match what was rendered on the server.
What broke
The application attempted to hydrate a React component, but the HTML generated on the server did not match the HTML generated on the client. This can lead to inconsistencies in the user interface.
Why it broke
This error typically occurs when there are differences in the rendering logic between the server and client, such as using non-deterministic values (like random numbers or dates) during the initial render.
How to fix
To fix this, ensure that the server and client render the same output. Avoid using non-deterministic values in the initial render and ensure that any data used is consistent across both environments.
Code fix
const MyComponent = () => { const date = new Date().toISOString(); return <div>{date}</div>; }; // Use a fixed date or pass it as a prop instead.Explained by ErrorOracle
Prevention tip
Avoid using non-deterministic values in the initial render and ensure that any data used is consistent across both environments.
