Talks:

Decluttering Sentry: One Knip at a Time

Decluttering Sentry: One Knip at a Time
By Dominik Dorfmeister

Ever wonder how much of your codebase is just… hanging around, doing nothing? At Sentry, we did too - and the answer was more than we expected. In this talk, I’ll share how we used Knip, a powerful tool for detecting unused files, exports, and dependencies, to declutter our frontend codebase.

You’ll learn about the practical steps we took to safely identify and remove dead code, how we integrated Knip into our workflows, about unexpected edge-cases and what we learned along the way.

Whether you're maintaining a massive monolith or just looking to tidy up, this session will give you practical strategies - and maybe a little inspiration - to start decluttering your own codebase, one Knip at a time.

Sentry

Sentry is the market leader in the error monitoring space and like many startups with engineer founders, Sentry was born out of frustration with technology. David started Sentry as an open-source side project in 2008. We started in a small community — the Django web framework — and over time expanded our technology to support dozens of other platforms, including browser JavaScript and mobile applications.
Fast forward to today, we're a $90M Series E company with a $3B valuation and 200+ employees on a mission to help developers write better software faster, so we can get back to enjoying technology. As one can see, the adventure continues exciting as we bring our developer-first Application Monitoring to more customers and industries worldwide.
Consider us for the ride - We're hiring a JavaScript developer!
