This is a guest post from Simon Grimm, creator of Galaxies.dev, where Simon helps developers learn React Native through fast-paced courses and personal support. Debugging React Native apps has traditionally been a bit of a pain. Developers usually ranked debugging as their biggest pain point of React Native, which, as we all know, makes up quite a lot of development time. But the good news is that things are getting better.

TTFB (Time to First Byte) is a commonly used metric that measures the duration between a client's HTTP request and the receipt of the first byte of the server's response. A lower TTFB means a more responsive server and faster page load times. In the past few years in the web dev world, we’ve seen a significant push towards rendering our websites on the server. Doing so is better for SEO and performs better on low-powered devices, but one thing we had to sacrifice is TTFB.

We’re expanding beyond just code coverage and added a suite of new capabilities to help you break production less: AI PR Review, AI Test Generation, Test Analytics, and Bundle Analysis.

Optimizing app performance can be challenging, even for seasoned developers. Frontends groan under the weight of bloated assets, backends lag from sluggish database queries, and mobile screens freeze at the worst times. But it doesn’t have to be that way. Sentry’s latest update brings domain-specific views to Insights & Profiling, giving developers the clarity they need to solve issues quickly.

What if you could not only find software issues you care about but also have the fix ready? We just introduced several updates that intelligently group new issues, reducing noise by about 40% and automatically suggesting fixes to annoying bugs you shouldn’t have to think about.
