Local Variables for NodeJS in Sentry
Stack traces show us exactly where an exception occurred, but you can still be left wondering: What arguments or state caused the exception to occur? If you can reproduce the issue locally with a debugger attached you’ll have access to these local variables, but with Sentry you can identify the exception location *without* needing to reproduce the issue locally. By including local variables with stack traces, Sentry events become much closer to the full debugging experience.

Understanding the Performance Impact of Generated JavaScript
There are major package size benefits to reducing the amount of generated JavaScript your package is creating. As part of our larger Javascript SDK package reduction, we spent a considerable effort to minify as much of our code as possible. If you’re looking to do the same, here are six improvements to consider.

Understanding the Performance Impact of Generated JavaScript
In the modern web, the JavaScript you write is often down-compiled using a compiler like Babel to make sure your JavaScript is compatible with older browsers or environments. In addition, if you are using TypeScript (like the Sentry SDK’s do) or something similar, you’ll have to transpile your TypeScript to JavaScript. Understanding how your code is being transpiled and downcompiled is important, because your bundle size is affected by your final generated JavaScript. This post is all about the technical prep work needed to ship a 0 bug reported major issue.

JavaScript SDK “Package Size is Massive” - So we reduced it by 29%
Developers started to notice just how big our JavaScript package was and yeah, we knew. We weren’t ignoring the issues; after all, we don’t want the Sentry package to be the cause of a slowdown. But to reduce our JavaScript SDK package size effectively we had to account for shipping new capabilities, like being able to manage the health of a release and performance monitoring, while maintaining a manageable bundle size. After all, new features == bigger package - usually.

How we trimmed the Sentry JavaScript SDK file size by 20%
SDKs naturally increase in size over time. After all, it does take more bytes to implement more features. This is not a big deal for most languages—the relative size of each new feature is small, and load times and storage aren’t big concerns for code running on a server. Larger JS bundles mean longer load times, which in turn increase user misery, which then can cause the user to leave pages entirely.
