Step.Run introduces a solution for enhancing the durability of APIs by allowing developers to add a single line of code to their REST APIs, thereby incorporating automatic retries and comprehensive observability without the need for additional infrastructure. Traditionally, achieving API reliability required complex setups involving queues or custom background systems, but Step.Run simplifies this process by providing a straightforward method to maintain a single code path, akin to improvements seen in backend jobs. This approach ensures APIs can handle crashes, deploys, and cold starts while offering a clear view of every request, input, output, and error to facilitate quick troubleshooting and iteration. The platform is currently in developer preview for Go, with plans to expand support to TypeScript, enabling developers to experience these enhancements in real-time through a dashboard that tracks and manages API requests seamlessly.
