Now more than ever, it’s complicated to publish an JavaScript library, especially if it’s open source. You have to keep in mind different JS runtimes, different TypeScript settings, and different bundler configurations – let’s not even get started on ESM vs. CJS.

We get a lot of questions from mobile developers about the difference between Sentry and Firebase Crashlytics, a lightweight crash reporting tool. In this workshop, we provided all the details you need to know to make an informed decision.

Today we’re taking another step by relicensing both Sentry and Codecov under a new license we’ve written called the Functional Source License (FSL). FSL is an evolution of BSL that deepens our commitment to balancing user freedom and developer sustainability. We think it is a compelling option for Open Source-minded SaaS companies such as ourselves who wish to grant freedom without harmful free-riding.

Today, we’re announcing new capabilities for emerging web development platforms and frameworks – like Bun, Deno, Next.js, and Remix – as well as improvements to our Mobile project onboarding flow. We’re also expanding our ecosystem reach with new APIs to make it easy to connect Sentry to any tool, key improvements to our existing integrations, and launching four new integrations: Opsgenie, Discord, Cloudflare Workers, and LaunchDarkly.

Like many of our customers, Sentry takes privacy and data sovereignty seriously. One of Sentry’s values is to be for “Every Developer,” and we can’t do that with a US-only data-solution. That’s why, starting next month all Sentry organizations will be able to choose where your Sentry data is hosted – either in the US or the EU.

We know, we’re Sentry the error and performance monitoring platform and we catch production issues. But some broken experiences simply won’t throw an exception. So we built a way to detect when your users are slamming their keys on the keyboard in frustration, and to even let them contact you directly when that doesn’t go their way.

Extracting relevant insights from your performance monitoring tool can be frustrating. You often get back more data than you need, making it difficult to connect that data back to the code you wrote. Sentry’s Performance monitoring product lets you cut through the noise by detecting real problems, then quickly takes you to the exact line of code responsible. The outcome: Less noise, more actionable results.

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. This workshop took place live on Oct 16, 2023 at React Advanced London.

As a follow-up to our first-ever FastAPI meetup in Berlin, this virtual event with Sebastian Ramirez, founder of FastAPI, and Salma Alam-Naylor, DevRel Advocate at Sentry answered all of the questions we didn’t get a chance to during the meetup, and also answered live Q&A from the audience.
