Modern applications often become complex black boxes when issues arise, making it difficult to pinpoint root causes across frontend and backend components. This talk reveals how distributed tracing transforms fragmented telemetry into actionable insights, empowering developers to diagnose problems faster and build more resilient systems.
Node.js module customization hooks let you expand functionality for use cases like dynamic patching, loading TypeScript files, and APM instrumentation. This talk walks through hands-on examples showing how to use these hooks to create more adaptable Node.js applications.
A deep dive into React error boundaries and the new error handling hooks introduced in React 19. Learn how Sentry leverages these capabilities to power debugging features for every developer.
Using ESM introduces a host of new observability challenges for server-side JavaScript applications. This talk walks through why those challenges exist and approaches you can take to make ESM observability work against all odds.
Publishing JavaScript libraries is complicated with different runtimes, TypeScript settings, bundler configurations, and the ESM vs CJS divide. This talk covers strategies for building robust libraries that are easy to use and stay working as JavaScript evolves.
Learn how to understand the performance of your OpenTelemetry instrumented applications with Sentry. This AMA covers how to turn raw telemetry data into actionable insights for tracing performance issues and surfacing errors.
The JavaScript you write is not the same as the JavaScript that runs in your browser, and understanding your final bundle is crucial for maximizing performance. This talk covers transpilation nuances, tree-shaking, minification, and loading strategies to help you optimize your generated JavaScript.
