Faster Code Feedback Loops With OpenTelemetry
What do you know about the code changes that were just introduced into the codebase? When will you start noticing if something goes wrong? Continuous feedback is a new dev practice that aims to shorten the feedback loop for developers by making runtime data available as you write the code. It allows developers to spot issues, code smells, and regressions early in the dev process, as well as instantly see how their code is used in test and even production environments – validating scalability and correct usage.
In this webinar, we'll take a look at Digma Continuous Feedback, a new and free plugin available on JetBrains Marketplace that collects OpenTelemetry data to provide live code feedback. We'll demonstrate how you can use Digma to analyze your application as you run and debug it without changing a single line of code. Finally, we'll walk through some practical code examples that highlight how continuous feedback provides linting, code lens, and analytics that can improve your code and enable new coding practices.
