Working with Sentry

Capture exceptions, add context, create performance spans, and use structured logging with Sentry.

Implement Working with Sentry

Capture exceptions, add context, create performance spans, and use structured logging with Sentry.

See:

Resource: using-sentry in Fullstack Recipes URL: https://fullstackrecipes.com/recipes/using-sentry Capturing Exceptions

Manually capture errors that are handled but should be tracked:

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

try { await riskyOperation(); } catch (err) { Sentry.captureException(err); // Handle the error gracefully... }

Adding Context

Attach user and custom context to errors:

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

// Set user context (persists for session) Sentry.setUser({ id: session.user.id, email: session.user.email, });

// Add custom context to exceptions Sentry.captureException(err, { tags: { feature: "checkout", plan: "pro", }, extra: { orderId: "order_123", items: cart.items, }, });

Performance Tracing

Create spans for meaningful operations:

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

// Wrap async operations const result = await Sentry.startSpan( { op: "http.client", name: "GET /api/users", }, async () => { const response = await fetch("/api/users"); return response.json(); }, );

// Wrap sync operations Sentry.startSpan( { op: "ui.click", name: "Submit Button Click", }, (span) => { span.setAttribute("form", "checkout"); processSubmit(); }, );

Using the Sentry Logger

Sentry provides structured logging that appears in the Logs tab:

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

const { logger } = Sentry;

logger.info("Payment processed", { orderId: "123", amount: 99.99 }); logger.warn("Rate limit approaching", { current: 90, max: 100 }); logger.error("Payment failed", { orderId: "123", reason: "declined" });

Breadcrumbs

Add breadcrumbs to provide context for errors:

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

// Automatically captured: console logs, fetch requests, UI clicks // Manual breadcrumbs for custom events: Sentry.addBreadcrumb({ category: "auth", message: "User signed in", level: "info", });

Clearing User Context

Clear user data on sign out:

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

async function signOut() { Sentry.setUser(null); await authClient.signOut(); }
