Nuxt on Cloudflare

If you're running your Nuxt app on Cloudflare Pages, you'll need to configure the Sentry Nuxt SDK slightly differently than the default setup. This guide will show you how to set up the SDK with Nitro's cloudflare-pages deployment preset.

Install

We recommend using the Sentry wizard to automatically install the SDK in your application:

npx @sentry/wizard@latest -i nuxt

If the setup through the wizard doesn't work for you, you can also set up the Nuxt SDK manually.

Setup

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

To use the SDK, you'll need to set either the nodejs_compat or nodejs_als compatibility flags in your wrangler.jsonc / wrangler.toml config. This is because the SDK needs access to the AsyncLocalStorage API to work correctly.

{
  "compatibility_flags": [
    "nodejs_als",
    // "nodejs_compat"
  ],
}

You will also want to add the CF_VERSION_METADATA binding:

{
  // ...
  "version_metadata": {
    "binding": "CF_VERSION_METADATA"
  },
}

Adding the Nitro Plugin

To enable Sentry for your Nuxt app on Cloudflare, follow these steps:

1. Delete the previous server config file sentry.server.config.ts if it exists.

2. Create a new file in server/plugins and add the following code to your plugin file:

import { sentryCloudflareNitroPlugin } from '@sentry/nuxt/module/plugins'

export default defineNitroPlugin(sentryCloudflareNitroPlugin({
  dsn: 'https://examplePublicKey@o0.ingest.sentry.io/0',
  tracesSampleRate: 1.0,
}))

Or, if you need access to nitroApp:

import { sentryCloudflareNitroPlugin } from '@sentry/nuxt/module/plugins'

export default defineNitroPlugin(sentryCloudflareNitroPlugin((nitroApp: NitroApp) => {
  // You can access `nitroApp` here if needed
  return {
    dsn: 'https://examplePublicKey@o0.ingest.sentry.io/0',
    tracesSampleRate: 1.0,
  }
}))
