Vue Monitoring made simple.

Monitor, troubleshoot, and optimize Vue app performance with Atatus. No code changes required in your app. Start seeing hidden Vue errors in minutes.

Install Setup Code

Copy & paste this code into the <head> tag of your html (every page) to start using Atatus on your Vue app. Please make sure that you add it before other script tags as well.

<script src="//"> </script>
<script type="text/javascript"> atatus.config('YOUR_API_KEY').install(); </script>
Replace the YOUR_API_KEY string with the API Key that is assigned for your project.

Add atatus to the vue.js error handler

function trackVueExceptions(atatus, Vue) {
  var Vue = Vue || window.Vue;
  var atatus = atatus || window.atatus;

  // quit if Vue isn't on the page
  if (!Vue || !Vue.config) return;

  // quit if atatus isn't on the page
  if (!atatus || !atatus.config) return;

  var _oldOnError = Vue.config.errorHandler;
  Vue.config.errorHandler = function VueErrorHandler(error, vm) {
      atatus.notify(error, {
        extra: {
          componentName: Vue.util.formatComponentName(vm),
          propsData: vm.$options.propsData

      if (typeof _oldOnError === 'function') {
, error, vm);

Questions and answers on Vue.js Error Monitoring

What is Vue.js monitoring?

Vue.js monitoring is the process of tracking and analyzing the performance and behavior of a Vue.js application in real-time. This includes monitoring key metrics such as page load time, memory usage, and error rates, as well as tracking user interactions and identifying areas for optimization.

Vue.js error monitoring can help developers identify and fix issues, improve the user experience, and optimize the overall performance of their application.

What are the most common performance issues in Vue.js applications and how can they be addressed?

Some common performance issues in Vue.js applications include slow page load times, high memory usage, and high CPU usage. These issues can be caused by a variety of factors, such as excessive data binding, inefficient rendering, and unoptimized code.

To address these issues, developers can implement various optimization techniques, such as reducing the number of watchers, using lazy-loading, and utilizing caching mechanisms.

Additionally, using tools like Vue.js error monitoring can help identify and diagnose performance issues, allowing developers to take corrective action.

How can Vue.js components be monitored for potential memory leaks?

To monitor Vue.js components for potential memory leaks, you can use the vm.$destroy() method to manually destroy each component instance when it is no longer needed. This will remove the component from the memory and prevent any potential memory leaks.

Additionally, you can use the Vue.config.errorHandler option to define a global error handler that will be called whenever there is an error in your Vue.js application, including potential memory leaks. This can help you identify and fix any issues before they become a problem.

What tools and techniques can be used to diagnose and debug Vue.js applications in production environments?

To diagnose and debug Vue.js applications in production environments, developers can use tools such as the Chrome DevTools, the Vue-devtools plugin, and error logging and monitoring tools such as Atatus.

These tools allow developers to track and analyze key metrics such as page load time, memory usage, and error rates in real-time, as well as identify and reproduce specific errors that occur in the application.

Additionally, techniques such as code splitting and lazy loading can help reduce the impact of errors and improve the overall stability of the application.

Consistent monitoring and performance testing can also help identify and address potential issues before they impact the user experience.

What are the best practices for monitoring and logging in Vue.js applications?
  1. Use the Vue.js browser devtools extension to monitor Vue component state and events in real-time.
  2. Use Vue.js error handling tools such as the vue-error-logger package to track and log runtime errors.
  3. Implement custom logging solutions using the Vue.js logging utility.
  4. Use third-party monitoring and logging tools that are compatible with Vue.js, such as Atatus.
  5. Monitor and log client-side performance metrics, such as page load times and memory usage, using tools like the li Vue.js performance monitoring tool.
  6. Regularly review and analyze logged data to identify potential issues and improve application performance.
  7. Use Vue.js error handling tools to track and log runtime errors.
  8. Set up alerts and notifications for key events and errors in the application.
  9. Implement logging and monitoring at the application, server, and network levels for comprehensive visibility.
What are some common metrics that should be monitored in Vue.js applications?

Some important metrics to monitor in a Vue application include:

  1. Page load times
  2. Memory usage
  3. CPU usage
  4. Network requests and response times
  5. User interactions and events
  6. Error rates and types
  7. Application and server performance metrics
  8. User behavior and engagement metrics
  9. Security and access logs
  10. Resource utilization, such as database and storage usage
  11. Database query performance and resource usage.
  12. Application-specific metrics, such as the number of active users, user's device type, and much more.
What is the average response time for Vue.js requests?

The average response time for Vue.js requests depends on a variety of factors, including the complexity of the application, the performance of the server and network, and the load on the system.

In general, Vue.js applications are known for their fast rendering times and smooth user experiences, and most requests should be completed in under a few hundred milliseconds.

However, it is important to monitor response times and identify any potential bottlenecks or performance issues that may impact the user experience.

How can Vue.js applications be tested and monitored for compatibility across different browsers and devices?

Use real-time monitoring tools, such as Atatus, to track the performance and availability of the application on different browsers and devices.

Use cross-browser testing tools, such as BrowserStack or Sauce Labs, to test Vue.js applications on a range of different browsers and operating systems.

Use responsive design techniques and frameworks, such as Bootstrap, to ensure that the application is compatible with a wide range of screen sizes and devices.

Regularly review user feedback and error logs to identify and address compatibility issues.

What are some common challenges and limitations of monitoring Vue.js applications, and how can they be overcome?

Some common challenges and limitations of monitoring Vue.js applications include:

  1. Lack of visibility into client-side performance and errors: Vue.js applications are primarily client-side, so it can be difficult to monitor and track performance and errors on the client-side. This can be overcome by using third-party monitoring tools such as Atatus Application performance monitorting that provide visibility into the client-side.
  2. Difficulty tracking and logging complex user interactions: Vue.js applications often involve complex user interactions, such as data updates and rendering, which can be difficult to track and log. This can be overcome by implementing custom logging solutions that are specific to the application's needs.
  3. Limited compatibility with third-party monitoring tools: Vue.js is a relatively new framework, so not all monitoring tools are compatible with it. This can be overcome by using tools that are specifically designed for Vue.js or by implementing custom monitoring solutions.
  4. Difficulty monitoring and logging server-side performance and errors: Vue.js applications typically rely on a server-side API or database, so it can be challenging to monitor and log server-side performance and errors. This can be overcome by using server-side monitoring tools and implementing custom logging solutions that integrate with the server-side.
