Encountering hydration failure during the development of Shopify application

Topic summary

Main issue: React hydration failure encountered while developing a Shopify app.

What hydration failure means: The client-side React app cannot attach to the server-rendered HTML because the markup or DOM differs between server and client.

Likely cause highlighted: Browser plugins/extensions that modify the DOM before React runs, creating a server–client content mismatch and triggering the error.

Recommended steps:

  • First verify your application code is correct to rule out logic or rendering mistakes.
  • Then check whether any browser plugins/extensions are enabled and temporarily disable them.

Proposed solution: Close/disable browser plugins to prevent DOM mutations prior to React hydration.

Status/outcome: A practical workaround is provided (disable extensions); no additional diagnostics, confirmations, or alternative causes are discussed. An image is attached but not essential to the guidance.

When this problem occurs, first make sure that the code you have written is correct. Finally, please pay close attention to whether the browser has enabled plugins, which will directly modify the DOM before React rendering, causing the content of the server and client to not match, triggering the Hydration failure error

Solution: Close the browser plugin
