Remix - backend (server) performance monitoring and tracing with express

[alexblack]

Hi, we're running Remix with express. I want to make sure our performance monitoring and tracing is setup as extensively as possible with Sentry.

The docs only seem to mention browser tracing for Remix. What about the server? Should we set it up as described for express?

https://docs.sentry.io/platforms/node/guides/express/

const Sentry = require("@sentry/node");
const Tracing = require("@sentry/tracing");
const express = require("express");
const app = express();

Sentry.init({
  dsn: "https://[email protected]/5633981",
  integrations: [
    // enable HTTP calls tracing
    new Sentry.Integrations.Http({ tracing: true }),
    // enable Express.js middleware tracing
    new Tracing.Integrations.Express({
      // to trace all requests to the default router
      app,
      // alternatively, you can specify the routes you want to trace:
      // router: someRouter,
    }),
  ],

  // We recommend adjusting this value in production, or using tracesSampler
  // for finer control
  tracesSampleRate: 1.0,
});

Thanks!

Hey @alexblack, we need to update our performance docs to make backend configuration more clear. For now you can see these instructions in https://docs.sentry.io/platforms/javascript/guides/remix/.

// entry.server.tsx
import { prisma } from "~/db.server";

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

Sentry.init({
  dsn: "https://[email protected]/0",
  tracesSampleRate: 1,
  integrations: [new Sentry.Integrations.Prisma({ client: prisma })],
  // ...
});

// server/index.ts
import { wrapExpressCreateRequestHandler } from "@sentry/remix";
import { createRequestHandler } from '@remix-run/express';

// ...

const createSentryRequestHandler = wrapExpressCreateRequestHandler(createRequestHandler);

// Use createSentryRequestHandler like you would with createRequestHandler
app.all('*', createSentryRequestHandler(/* ... */));

Thanks. So just double checking: I don't need to add either of the tracing integrations that your docs say are needed for express? (Does sentry add those for me?)

Yup! If you add a sample rate, the Remix SDK will add this out of the box.

Perfect, thanks
