#error monitoring

If finding errors in your frontend project is like searching for a needle in a code haystack, then Sentry error monitoring can be your metal detector. Learn the basics of error monitoring with Sentry. Whether you are running a React, Angular, Vue, or just “vanilla” JavaScript, see how Sentry can help you find the who, what, when and where behind errors in your frontend project.

During this session you will learn how to create a new Rollbar account and integrate the Rollbar SDK with your application to monitor errors in real-time and respond and fix those errors. We will also cover how to customize payload data sent to Rollbar to extend your monitoring capabilities.

Agenda:- Create a Rollbar Account (Free Account)- Integrate your application with the Rollbar SDK- Send handled and unhandled errors to Rollbar- Add Custom payload data to your configuration.

You know that annoying bug? The one that doesn’t show up locally? And no matter how many times you try to recreate the environment you can’t reproduce it? You’ve gone through the breadcrumbs, read through the stack trace, and are now playing detective to piece together support tickets to make sure it’s real.
Join Sentry developer Ryan Albrecht in this talk to learn how developers can use Session Replay - a tool that provides video-like reproductions of user interactions - to identify, reproduce, and resolve errors and performance issues faster (without rolling your head on your keyboard).

- Errors? How to render and log your server and client errorsa - When to return errors vs throwb - Setup logging service like Sentry, LogRocket, and Bugsnag- Forms? How to validate and handle multi-page formsa - Use zod to validate form data in your actionb - Step through multi-page forms without losing data- Stuck? How to patch bugs or missing features in Remix so you can move ona - Use patch-package to quickly fix your Remix installb - Show tool for managing multiple patches and cherry-pick open PRs- Users? How to handle multi-tenant apps with Prismaa - Determine tenant by host or by userb - Multiple database or single database/multiple schemasc - Ensures tenant data always separate from others

We’ll go through setting up Sentry step--step to get visibility into our frontend and backend. Once integrated, we will track and triage errors + transactions surfaced Sentry from our services to understand why/where/how errors and slowdowns occurred within our application code.

Join Sentry’s Evan Purkhiser and David Wang as they walk through Sentry’s 230k LoC Typescript/React codebase. They’ll tell war stories of the good, the bad, and the ugly. Gaze in wonder at their modern usage of Typescript, react hooks, and styled components. Recoil in disgust at their legacy Reflux usage and perplexing Webpack configuration. Step away from the workshop with a working knowledge of techniques to keep a large-scale frontend codebase modern and maintainable.
