Good news, everyone! Today, we’re proud to announce the launch of our fully-fledged JavaScript error tracking for your front-end applications. From today, you’ll have even more complete insights into your Ruby and Elixir apps — your back-end errors, performance metrics, host metrics, custom metrics and your front-end errors can now all come together under a single interface.
