Quick tour of the VSCode Lightrun plugin

The majority of the work you do with Lightrun, such as troubleshooting, debugging, and performance testing, is performed directly from your integrated development environment (IDE) or the Lightrun CLI.

Using the Lightrun plugin, provided for a variety of popular IDEs (such as VSCode, IntelliJ, and PyCharm), you can insert Lightrun actions (Logs, Metrics, and Snapshots) anywhere within the source code of your running applications. Also, from within the Lightrun plugin for your IDE, you can view, in real time, the output of Lightrun actions.

And, thanks to Lightrun's comprehensive range of integrations with third-party logging tools, from the plugin, you also can route output from Lightrun Logs and Metrics to your usual logging framework (such as and DataDog).
