New Raygun JS provider v2.27.0 to support performance timing

The popular chromium based browser ecosystem has recently changed how performance metrics can be collected in relation to performance.timing. Before we get into the details, the TLDR is: if you use the Raygun CDN for raygun4js, you’re up to date. If you self-host raygun4js and use Raygun Real User Monitoring, you’ll want to upgrade to version 2.27.0.

The State of Client-Side JavaScript Errors

As JavaScript has grown more prevalent on the web, so have JavaScript errors. As an error monitoring service, we have a unique perspective on how errors impact the web globally, and we are constantly learning more about how the web breaks. We’re thrilled to share this report today so we can all understand it better, and build a better web. We produce this report every week, you can check it out anytime via the free Global Error Statistics report.

Support for Next.js Middleware and Edge Routes

Third-party JavaScript libraries provide developers with the tools they need to build modern web experiences, and a bit of cheatcode at times to not have to start from scratch. I mean, you don’t want to build an entire monitoring solution, so we help with Sentry’s Next.js SDK that only requires a couple of lines of code.

Best Search Packages for JavaScript

The demand for search functionality is growing, and many developers are trying to incorporate it into their applications. However, building one from scratch is challenging and time-consuming. Fortunately, many open-source libraries are available to relieve developers of this burden. This guide will provide the reader with a list of some of the best search packages for JavaScript.

Take control of monitoring and responding to your production Frontend Javascript errors

We are very lucky on the Rollbar Customer Engineering Team because we get to work with many many development teams. Each team develops, tests, and deploys their applications in their own way. They have chosen different languages and frameworks to solve their particular problem. We learn from each team that we work with, and share these learnings to our Product Design team.

Common Errors in Next.js and How to Resolve Them

Bugs are one of the most troubling aspects of software development; they appear out of nowhere and cause everything to stop working. Most of the time, they can be resolved quickly; however, others can be gruesome and take hours/days to fix. Next.js is one of the most popular web development frameworks in the current world, and as a programming tool, it didn’t escape the bug dilemma either.

How We Made JavaScript Stack Traces Awesome

Sentry helps every developer diagnose, fix, and optimize the performance of their code, and we need to deliver high quality stack traces in order to do so. You might have noticed a significant improvement in Sentry JavaScript stack traces recently. In this blog post, we want to explain why source maps are insufficient for solving this problem, the challenges we faced, and how we eventually pulled it off by parsing JavaScript.

JavaScript immediately invoked function expressions

JavaScript Immediately Invoked Function Expressions (IIFEs) are functions that are executed when they are initialized. An IIFE (pronounced “iffy”) can be initialized or defined to achieve a certain purpose. In this tutorial, you will learn about use cases for IIFEs and the benefits of using them over traditional functions. You will also write tests for your functions and integrate CI/CD for these tests.
