For React specifically, you can log React state updates to audit how your global state changes. You should log important events, such as the completion of user requests. In contrast, logging is a means of auditing to keep track of things happening within an application. You ensure your application can continue to operate normally with little impact on the user experience. As Charles1303 describes in his dev.to article, “Exception handling can be seen as a way of providing Resilience to our application.” In other words, if you handle exceptions, your application won’t crash when it throws an exception. Exception handling refers to catching errors and handling them gracefully without impacting the user experience this might include showing a blank page or error message, for example. Error Handlingįirst, let’s discuss error handling (also called exception handling).
So, how are the concepts of error handling and logging closely related? To answer this question, let’s define both concepts. What’s the Synergy Between Error Handling and Logging? The connection between these concepts applies to all programming languages and frameworks, not just React. But first, it’s important for you to understand the close relationship between the concepts of error handling and logging. This article provides you with best practices for handling errors in React and logging them persistently. For this reason, we need a better way to log important events. However, this isn’t advised because whenever you refresh the webpage, you can’t access the logged data anymore. Often, React developers choose to use the console.log statement to log important data, such as an error stack trace, to the developer console.
For example, a high number of failed login attempts might indicate someone tried to gain illicit access to your application. Log aggregation platforms allow for log analysis and the creation of advanced alerting mechanisms to detect anomalies. Furthermore, you can use log data to track various metrics such as HTTP error rates, failed login attempts, and overall application availability. Logging is essential for understanding what’s happening within your running code.
