Vue

On this page, we get you up and running with Sentry's SDK, so that it will automatically report errors and exceptions in your application.

Don't already have an account and Sentry project established? Head over to sentry.io, then return to this page.

Install

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

Copied
npm install --save @sentry/vue @sentry/tracing

Configure

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

To initialize Sentry in your Vue application, add this to your app.js:

Vue 2

Copied
import Vue from "vue";
import Router from "vue-router";
import * as Sentry from "@sentry/vue";
import { Integrations } from "@sentry/tracing";

Vue.use(Router);

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

Sentry.init({
  Vue,
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
  integrations: [
    new Integrations.BrowserTracing({
      routingInstrumentation: Sentry.vueRouterInstrumentation(router),
      tracingOrigins: ["localhost", "my-site-url.com", /^\//],
    }),
  ],
  // Set tracesSampleRate to 1.0 to capture 100%
  // of transactions for performance monitoring.
  // We recommend adjusting this value in production
  tracesSampleRate: 1.0,
});

// ...

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

Vue 3

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

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

Sentry.init({
  app,
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
  integrations: [
    new Integrations.BrowserTracing({
      routingInstrumentation: Sentry.vueRouterInstrumentation(router),
      tracingOrigins: ["localhost", "my-site-url.com", /^\//],
    }),
  ],
  // Set tracesSampleRate to 1.0 to capture 100%
  // of transactions for performance monitoring.
  // We recommend adjusting this value in production
  tracesSampleRate: 1.0,
});

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

Additionally, Vue 3 allows you to use multiple apps with the same Sentry SDK instance, as well as add more apps dynamically after the SDK has been already initialized.

Vue 3 - Multiple Apps

Copied
const appOne = Vue.createApp(App);
const appTwo = Vue.createApp(App);
const appThree = Vue.createApp(App);

Sentry.init({
  app: [appOne, appTwo, appThree],
});

Vue 3 - Manual Initialization

Copied
import * as Sentry from "@sentry/vue";

// ...
const app = createApp(App);

Sentry.init({
  app,
  // ...
});

const miscApp = createApp(MiscApp);
miscApp.mixin(Sentry.createTracingMixins({ trackComponents: true }));
Sentry.attachErrorHandler(miscApp, { logErrors: true });

The SDK accepts a few different configuration options that let you change its behavior:

  • attachProps (defaults to true) - Includes all Vue components' props with the events.
  • logErrors (defaults to false) - Decides whether SDK should call Vue's original logError function as well.
  • trackComponents (defaults to false) - Decides whether to track components by hooking into its lifecycle methods. Can be set to either boolean, to enable/disable tracking for all of them, or to an array of specific component names (case-sensitive).
  • timeout (defaults to 2000) - Time in milliseconds dictating how long to wait until the tracked root activity is marked as finished and sent off to Sentry.
  • hooks (defaults to ['activate', 'mount', 'update']) - List of hooks to keep track of during component lifecycle 'activate' | 'create' | 'destroy' | 'mount' | 'unmount' | 'update'.

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:

App.vue
Copied
// ...
<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 open your project. Clicking on the error's title will open a page where you can see detailed information and mark it as resolved.
