React's New Controversial Override
Theo - t3․gg・15 minutes read
React reverted a change related to Fetch but plans to implement it again to address hydration errors in React applications by patching the date API during server-side rendering to prevent mismatches and ensure standards compliance. This patch aims to address hydration errors caused by date and time discrepancies, potentially reducing complaints in the future by ensuring consistency between server-side rendering and client-side hydration.
Insights
- React recently reverted a change related to Fetch but plans to reimplement it to address hydration errors in React applications, focusing on server-side adjustments to prevent mismatches in components.
- The React team's approach to patching built-in APIs during server-side rendering aims to ensure standards compliance and avoid controversies like "smoosh gate," emphasizing the importance of aligning server-generated HTML with client-generated HTML to prevent hydration errors.

How does React plan to address hydration errors?
React plans to patch the date API during server-side rendering (SSR) and hydration to prevent mismatches, ensuring that the time returned during hydration matches the time used during SSR. This patch aims to reduce complaints in the future by addressing the common issue of hydration errors caused by date and time discrepancies.
What is considered acceptable when patching built-in APIs in React?
Patching built-in APIs in React is considered acceptable if the behavior is standards-compliant. The React team focuses on server-side adjustments rather than client-side JavaScript changes, aiming to ensure that any patches align with industry standards.
Can hydration errors in React applications be avoided?
Hydration errors in React applications, which occur when server-generated HTML differs from client-generated HTML, leading to mismatches in React components, can be avoided by restructuring code to run only on the server or client, not both. This restructuring helps prevent discrepancies that cause hydration errors.
What was the controversial patching issue involving MooTools and React?
An example of a controversial patching issue was "smoosh gate," which involved the MooTools library and the array prototype flatten feature. This incident highlighted the importance of ensuring that any patches made by the React team are standards-compliant and do not lead to compatibility issues.
What is the focus of React's patching efforts in addressing hydration errors?
React's patching efforts in addressing hydration errors primarily focus on server-side adjustments rather than client-side JavaScript changes. By patching the date API during server-side rendering (SSR) and hydration, React aims to prevent mismatches caused by date and time discrepancies, improving the overall performance and reliability of React applications.
