Koa is a Node.js-based web application and API framework that offers an expressive, robust foundation. Designed by the same team that designed Express.js, Koa leverages generators so that developers may eschew callbacks and improve error handling. Unlike similar frameworks, Koa does not use middleware within its core, and as a result has an especially small footprint. Instead Koa-based applications are objects that contain an array of middleware generator functions. Developers can compose and execute these functions in a stack-like manner by request. Common tasks include proxy support, content negotiation, redirection, and cache freshness.
With the AppDynamics platform you can monitor, troubleshoot and diagnose performance issues in your Node.js applications built on the Koa framework – in real time, and in production.
Understand which functions are blocking the event loop and maxing out CPU with a call graph of all executing functions within the Node.js process that executed.
Choose which business transactions are most important for you to monitor and include or exclude them from view in real-time.
Understand the impact of database performance by correlating database performance to originating business transaction performance metrics.
Dive deep into an individual business transaction with a complete call graph view per unique business transaction. (coming soon)
Understand how client-side performance correlates to the server transaction by correlating browser and device performance to the originating business transaction performance metrics. (coming soon)
Choose to deploy our platform via SaaS or on-premise with the ability for Node.js agents to report into an on-premises controller. (coming soon)
