Common React Issues Solved

Hydration Errors

Whether it's a flickering UI or missing elements, Sentry's hydration error diff tools make it easy to instantly detect and debug mismatches between server-rendered and client-rendered HTML.

Component Performance Issues

Monitor React component render times and identify slow updates that impact user experience.

State Management Debugging

Track Redux actions and state transitions to understand what changed before an issue occurred.

Prevent Silent Failures in Scheduled Tasks

Missed background syncs or failed API updates can go unnoticed, leading to broken functionality. Ensure your scheduled tasks are running on time and without errors with Sentry’s monitoring tools

Detect Downtime

Get real-time alerts when your application is unavailable, so you can respond quickly before it impacts your users.

FAQs

When debugging, logs, traces, and errors work better together. Logs provide the granular context—like retries, API failures, and internal state—that spans and errors can miss. But in most tools today, logs live in a separate system, forcing you to switch between tools to piece together the full picture.

With logs in Sentry, everything is in one place. You can see logs right alongside your errors and traces—no more context switching, just faster debugging.

Sentry doesn’t impact a web site’s performance.

If you look at the configuration options for when you initialize Sentry in your code, you’ll see there’s nothing regarding minimizing its impact on your app’s performance. This is because our team of SDK engineers already developed Sentry with this in mind.

Sentry is a listener/handler for errors that asynchronously sends out the error/event to Sentry.io. This is non-blocking. The error/event only goes out if this is an error.

Global handlers have almost no impact as well, as they are native APIs provided by the browsers.
