+title: TanStack Start on Cloudflare
+description: "Learn how to instrument your TanStack Start app on Cloudflare Workers and capture your first errors with Sentry."
+---
+
+
+
+
+
+This guide is for TanStack Start deployed to **Cloudflare Workers** using the `@cloudflare/vite-plugin`. For Node.js-based deployments, see our [TanStack Start guide](/platforms/javascript/guides/tanstackstart-react/).
+
+
+
+
+
+## Install
+
+Choose the features you want to configure, and this guide will show you how:
+
+
+
+
+
+### Install the Sentry SDK
+
+
+
+
+
+Run the command for your preferred package manager to add the Sentry SDK to your application:
+
+
+
+
+
+
+
+
+
+
+## Configure
+
+When deploying TanStack Start to Cloudflare Workers, you need to wrap the server entry point with `Sentry.withSentry` from `@sentry/cloudflare`. TanStack Start allows you to create a custom server entry file for this purpose.
+
+### Wrangler Configuration
+
+
+
+### Create a Custom Server Entry
+
+
+
+
+
+Create a `src/server.ts` file that wraps the TanStack Start handler with Sentry:
+
+
+
+
+```typescript {filename:src/server.ts}
+import * as Sentry from "@sentry/cloudflare";
+import handler from "@tanstack/react-start/server-entry";
+
+export default Sentry.withSentry(
+ (env) => ({
+ dsn: env.SENTRY_DSN,
+ // Adds request headers and IP for users, for more info visit:
+ // https://docs.sentry.io/platforms/javascript/guides/cloudflare/configuration/options/#sendDefaultPii
+ sendDefaultPii: true,
+ // ___PRODUCT_OPTION_START___ logs
+
+ // Enable logs to be sent to Sentry
+ enableLogs: true,
+ // ___PRODUCT_OPTION_END___ logs
+ // ___PRODUCT_OPTION_START___ performance
+
+ // Set tracesSampleRate to 1.0 to capture 100% of spans for tracing.
+ tracesSampleRate: 1.0,
+ // ___PRODUCT_OPTION_END___ performance
+ }),
+ handler
+);
+```
+
+
+
+
+
+### Update Wrangler Configuration
+
+
+
+
+
+Update your `wrangler.jsonc` (or `wrangler.toml`) to use your custom server entry:
+
+
+
+
+```json {diff} {filename:wrangler.jsonc}
+ {
+ "name": "my-tanstack-app",
++ "main": "src/server.ts",
+ // ... rest of config
+ }
+```
+
+
+
+
+
+### Configure Client-Side Sentry
+
+
+
+
+
+Initialize Sentry in your `src/router.tsx` file for client-side error tracking:
+
+
+
+
+```tsx {diff} {filename:src/router.tsx}
++import * as Sentry from "@sentry/tanstackstart-react";
+ import { createRouter } from '@tanstack/react-router'
+
+export const getRouter = () => {
+ const router = createRouter();
+
++ if (!router.isServer) {
++ Sentry.init({
++ dsn: "___PUBLIC_DSN___",
++ integrations: [
++ // ___PRODUCT_OPTION_START___ performance
++ Sentry.browserTracingIntegration(),
++ // ___PRODUCT_OPTION_END___ performance
++ ],
++ // ___PRODUCT_OPTION_START___ performance
++ tracesSampleRate: 1.0,
++ // ___PRODUCT_OPTION_END___ performance
++ });
++ }
+
+ return router;
+}
+```
+
+
+
+
+
+### Add Readable Stack Traces With Source Maps (Optional)
+
+
+
+## Verify Your Setup
+
+
+
+
+
+To verify Sentry is capturing errors, add a test button to one of your pages:
+
+
+
+
+```tsx
+
+```
+
+
+
+
+
+Run your app with `wrangler dev` (or through your Vite build with Cloudflare plugin), click the button, and check your Sentry project for the error.
+
+
+
+## Next Steps
+
+At this point, you should have integrated Sentry and should already be sending data to your Sentry project.
+
+Now's a good time to customize your setup and look into more advanced topics. Our next recommended steps for you are:
+
+- Learn how to [manually capture errors](/platforms/javascript/guides/cloudflare/usage/)
+- Continue to [customize your configuration](/platforms/javascript/guides/cloudflare/configuration/)
+- Make use of [Cloudflare-specific features](/platforms/javascript/guides/cloudflare/features)
+- Get familiar with [Sentry's product features](/product) like tracing, insights, and alerts
+
+
+
+- Check out setup instructions for other popular [frameworks on Cloudflare](/platforms/javascript/guides/cloudflare/frameworks/)
+- Find various support topics in troubleshooting

This means that the Sentry SDK will not capture data from database calls, queues, ORMs, third-party libraries, or other framework-specific data.
Thus, we recommend you follow the [`--import` flag setup instructions](#with---import-flag-eg-nodejs-server) if possible.
