Sentry Ignore Errors - Javascript

Sentry is a popular error tracking tool that enables developers to easily identify, diagnose and resolve errors in their web applications. One of the key features of Sentry is the ability to ignore errors, which can be useful in certain scenarios. In this article, we will explore what Sentry ignore errors are and how to use them in Javascript applications.

What are Sentry Ignore Errors?

Sentry ignore errors allow developers to tell Sentry to ignore certain errors that occur in their application. This can be useful in situations where errors are expected or are not critical enough to warrant attention. By ignoring these errors, developers can reduce the noise in their error logs and focus on more critical issues.

How to Use Sentry Ignore Errors in Javascript

To ignore errors in Sentry, developers need to use Sentry's API to set up a filter condition. This filter condition can then be used to exclude certain errors from being reported to Sentry.

Here's an example of how to use Sentry ignore errors in a Javascript application:

const filter = {
  shouldIgnore: (event, hint) => {
    if (event.exception && event.exception.values[0].type === 'CustomError') {
      return true;
    }
    return false;
  }
};
Sentry.addGlobalEventProcessor(event => event && filter.shouldIgnore(event) ? null : event);

In this example, we are using Sentry's addGlobalEventProcessor method to set up a filter condition. The shouldIgnore function checks if the error is a CustomError type and returns true if it is. If the function returns true, Sentry will ignore that error and it will not be reported.

Conclusion

Sentry ignore errors can help developers reduce the noise in their error logs and focus on more critical issues. By setting up filter conditions, developers can tell Sentry to ignore certain errors that they know are not critical or expected. If you're using Sentry in your Javascript application, be sure to explore the ignore errors feature and see if it can help simplify your error tracking.
