    APIToolkit gets the job done

    APIToolkit is a really handy monitoring tool. This middleware is doing basically everything I needed and more. I worry less about downtime and payload anomalies, and I get to monitor my API performance and metrics on my dashboard. The auto-documentation feature is a great addition. And so far, everything is going seamlessly alright. I hope it remains that way.

    In today’s fast-paced, API-driven world, traditional observability tools are no longer enough. While metrics, traces, and logs are essential, they don’t give you the full picture—especially when it comes to APIs. With APItoolkit, you gain deeper insights, proactive error detection, and the context you need to keep your APIs—and your entire application—running smoothly. So if you like to track all the live users'... - Source: dev.to / 9 months ago

    The above implementation demonstrates how you can easily detect breaking changes in an API using Merkle trees. Merkle trees provide an efficient way to ensure data integrity because the hashed value of the same data remains unchanged. This approach is superior to comparing JSON objects directly, as it avoids the complexity of traversing each key and value to verify that the shape and structure are consistent.... - Source: dev.to / 12 months ago
