The ever-growing demand for highly performant and scalable systems has made caching an essential aspect of software development. Efficient caching strategies contribute significantly to improving user experience while reducing the burden on backend systems. In this talk, we will delve into the fundamentals of caching in Node.js, and introduce "layered-loader", a sophisticated open source Node.js caching library, designed and fine-tuned for the low-latency, high-throughput systems.

The talk will be structured into three segments:

* Caching in Node.js
** Brief introduction to caching and its significance in high load systems.
** Caveats and gotchas of implementing caching in Node.js.

* The Elegance of Layered Caching:
** Unraveling the concept of layered caching and the challenges it resolves.

* "layered-loader": Node.js Caching Evolved:
** Introducing the brand new Node.js caching library, "layered-loader"
** Exploring the key features and advantages of "layered-loader", including its efficient layered caching approach, high performance, and seamless integration capabilities.
** Case study of using "layered-loader" for scaling the most demanding service in Lokalise.
