Responding to and ignoring notifications can be a full-contact sport. It makes sense, though, from GitHub, Slack, to Jira and Sentry; our world revolves around robots telling us everything is important, critical, and urgent. Just like that, it’s near impossible to see what actually matters so you can solve quicker and more comprehensively.
Recently, Sentry converted 100% of its frontend React codebase from JavaScript to TypeScript. This year-long effort spanned over a dozen members of the engineering team, 1,100 files, and 95,000 lines of code. In this blog post, we share our process, techniques, challenges, and ultimately, what we learned along this journey.
From testing in production to running A/B tests, feature flags have a range of uses. At Sentry, one way we use feature flags is to safely allow beta access to new features for some of our “Early Adopter” customers. Because you can set multiple combinations of feature flags, every user is likely to have a different experience.
