Manual Setup

Learn how to set up the SDK manually.

If you can't (or prefer not to) run the automatic setup, you can follow the instructions below to configure your application.

Get started by installing the Sentry Remix SDK:

npm install @sentry/remix --save

To use this SDK, initialize Sentry in your Remix project for both the client and server.

import { useLocation, useMatches } from "@remix-run/react";
import * as Sentry from "@sentry/remix";
import { useEffect } from "react";

  dsn: "",
  integrations: [
    // Replay is only available in the client

  // 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 distributed tracing 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,

To capture errors from ErrorBoundary, you should define your own ErrorBoundary in root.tsx and use Sentry.captureRemixErrorBoundaryError inside of it. You can also create route-specific error capturing behavior by defining ErrorBoundary in your route components. The ErrorBoundary you define in root.tsx will be used as a fallback for all routes.

import { captureRemixErrorBoundaryError } from "@sentry/remix";

export const ErrorBoundary: V2_ErrorBoundaryComponent = () => {
  const error = useRouteError();


  return <div> ... </div>;

To catch React component errors (in Remix v1) and routing transactions (in all Remix versions), wrap your Remix root with withSentry.

If you use Remix v1 with the v2_errorBoundary future flag, you must also configure your ErrorBoundary.

import {
} from "@remix-run/react";

import { withSentry } from "@sentry/remix";

function App() {
  return (
        <Meta />
        <Links />
        <Outlet />
        <ScrollRestoration />
        <Scripts />
        <LiveReload />

export default withSentry(App);

If you use Remix v2, wrapWithErrorBoundary is disabled by default. You still need to wrap your root component with withSentry to capture routing transactions.

You can disable or configure ErrorBoundary using a second parameter to withSentry.

withSentry(App, {
  wrapWithErrorBoundary: false,

// or

withSentry(App, {
  errorBoundaryOptions: {
    fallback: <p>An error has occurred</p>,

Create an instrumentation file (named here as instrument.server.mjs) in your project. Add your initialization code in this file for the server-side SDK.

import * as Sentry from "@sentry/remix";

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

  // To use Sentry OpenTelemetry auto-instrumentation
  // default: false
  autoInstrumentRemix: true,

  // Optionally capture action formData attributes with errors.
  // This requires `sendDefaultPii` set to true as well.
  captureActionFormDataKeys: {
    key_x: true,
    key_y: true,
  // To capture action formData attributes.
  sendDefaultPii: true

Then run your Remix server with:

NODE_OPTIONS='--import=./instrument.server.mjs' remix-serve build
# or
NODE_OPTIONS='--require=./instrument.server.cjs' remix-serve build

If you use the Express server instead of the Remix built-in server, you can alternatively import your instrumentation file directly at the top of your server implementation. See the example here.

Sentry's Remix SDK will automatically record your action and loader transactions, as well as server-side errors. You can also initialize Sentry's database integrations, such as Prisma, to get spans for your database calls.

To capture server-side errors automatically, instrument the handleError function in your server entry point.

If you're using Sentry Remix SDK version 7.87.0 or higher, you can wrap your error handler with wrapHandleErrorWithSentry or use sentryHandleError to export as your handleError function.

entry.server.tsx (@sentry/remix >= 7.87.0)
import * as Sentry from "@sentry/remix";

export const handleError = Sentry.wrapHandleErrorWithSentry(
  (error, { request }) => {
    // Custom handleError implementation

// Alternative: Use the Sentry utility function if you don't need to wrap a custom function
export const handleError = Sentry.sentryHandleError;

For SDK versions older than 7.87.0, you can use Sentry.captureRemixServerException to capture errors inside handleError.

entry.server.tsx (@sentry/remix < 7.87.0)
export function handleError(
  error: unknown,
  { request }: DataFunctionArgs,
): void {
  if (error instanceof Error) {
    Sentry.captureRemixServerException(error, "remix.server", request);
  } else {
    // Optionally capture non-Error objects

After you've completed this setup, the SDK will automatically capture unhandled errors and promise rejections, and monitor performance in the client. You can also manually capture errors.

You can refer to Remix Docs to learn how to use your Sentry DSN with environment variables.

To enable readable stack traces, configure source maps upload for your production builds.

You can import your server instrumentation file at the top of your Express server implementation.

// import the Sentry instrumentation file before anything else.
import "./instrument.server.mjs";
// alternatively `require('./instrument.server.cjs')`

// ...

const app = express();

// ...
