Features

In addition to capturing errors, you can monitor interactions between multiple services or applications by enabling tracing. You can also get to the root of an error or performance issue faster, by watching a video-like reproduction of a user session with session replay.

Select which Sentry features you'd like to install in addition to Error Monitoring to get the corresponding installation and configuration instructions below.

Install

Sentry captures data by using an SDK within your application’s runtime.

npm install @sentry/vue --save

Configure

Configuration should happen as early as possible in your application's lifecycle.

To initialize Sentry in your Vue application, add the following code snippet to your main.js:

Vue 3

import { createApp } from "vue";
import { createRouter } from "vue-router";
import * as Sentry from "@sentry/vue";

const app = createApp({
  // ...
});
const router = createRouter({
  // ...
});

Sentry.init({
  app,
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
  integrations: [
    Sentry.browserTracingIntegration({ router }),
    Sentry.replayIntegration(),
  ],

  // Set tracesSampleRate to 1.0 to capture 100%
  // of transactions for tracing.
  // We recommend adjusting this value in production
  tracesSampleRate: 1.0,

  // Set `tracePropagationTargets` to control for which URLs trace propagation should be enabled
  tracePropagationTargets: ["localhost", /^https:\/\/yourserver\.io\/api/],

  // Capture Replay for 10% of all sessions,
  // plus for 100% of sessions with an error
  replaysSessionSampleRate: 0.1,
  replaysOnErrorSampleRate: 1.0,
});

app.use(router);
app.mount("#app");

Vue 2

import Vue from "vue";
import Router from "vue-router";
import * as Sentry from "@sentry/vue";

Vue.use(Router);

const router = new Router({
  // ...
});

Sentry.init({
  Vue,
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
  integrations: [
    Sentry.browserTracingIntegration({ router }),
    Sentry.replayIntegration(),
  ],

  // Set tracesSampleRate to 1.0 to capture 100%
  // of transactions for tracing.
  // We recommend adjusting this value in production
  tracesSampleRate: 1.0,

  // Set `tracePropagationTargets` to control for which URLs trace propagation should be enabled
  tracePropagationTargets: ["localhost", /^https:\/\/yourserver\.io\/api/],

  // Capture Replay for 10% of all sessions,
  // plus for 100% of sessions with an error
  replaysSessionSampleRate: 0.1,
  replaysOnErrorSampleRate: 1.0,
});

// ...

new Vue({
  router,
  render: (h) => h(App),
}).$mount("#app");

If you're creating more than one Vue 3 app within your application, check out how to initialize the SDK for multiple apps.

Vue-Specific configuration

The SDK accepts a few Vue-specific Sentry.init configuration options:

• attachProps (defaults to true) - Includes all Vue components' props with the events.
• logErrors (defaults to true) - Decides whether SDK should call Vue's original logError function as well.
• trackComponents (defaults to false) - Track your app's components. Learn more about component tracking and all its options.

Late-Defined Vue Apps

If the Vue application is not defined from the start, you can add error monitoring for Vue-specific errors later on. To manually add the integration for late-defined Vue applications check out the docs for the Vue Integration.

Add Readable Stack Traces to Errors

Depending on how you've set up your project, the stack traces in your Sentry errors probably won't look like your actual code.

To fix this, upload your source maps to Sentry. The easiest way to do this is by using the Sentry Wizard:

npx @sentry/wizard@latest -i sourcemaps

The wizard will guide you through the following steps:

• Logging into Sentry and selecting a project
• Installing the necessary Sentry packages
• Configuring your build tool to generate and upload source maps
• Configuring your CI to upload source maps

For more information on source maps or for more options to upload them, head over to our Source Maps documentation.

Verify

This snippet includes an intentional error, so you can test that everything is working as soon as you set it up.

Add a button to your page that throws an error:

// ...
<button @click="throwError">Throw error</button>
// ...

export default {
  // ...
  methods: {
    throwError() {
      throw new Error('Sentry Error');
    }
  }
};

To view and resolve the recorded error, log into sentry.io and select your project. Clicking on the error's title will open a page where you can see detailed information and mark it as resolved.
