How to Debug Hydration Mismatch Issues Efficiently?

[chiaweilee]

When there's an issue, there are no error messages in the development environment. Errors only appear after building and previewing, but it's impossible to locate the problematic area based on the error information. Currently, I rely on commenting out code to isolate the problematic module and then investigate the cause, which becomes increasingly difficult as the codebase grows. Is there a better way to handle this?

You can run DEBUG=true vitepress build && vitepress preview to see bit detailed errors. Most common cause is usually invalid HTML. You can use some service like https://validator.w3.org/#validate_by_input to check the html on page where hydration is failing.
