Cloudflare Workers

Cloudflare Workers are computing instances on the edges of the internet. They’re purposely built to be lightweight, isolated, and distributed – these features are meant to achieve speed, security and economy. They’re used to run user-defined applications, such as augmenting web requests but at an intermediate point between the origin server and the user.

In this post I’ll go over the What, How, and basic code structure to build up to a fleshed out use case in the future.

I recently learned of a neat Cloudflare tool to that lets developers deploy “serverless code”: Cloudflare Workers. It approximates AWS Lambda in being a compute instance that lives in closer to the edge of the users' site, and it’s fast at doing what it does. “Just deploy code” in your choice of language: Javascript, Rust, Python, C/C++… and you needn’t preoccupy yourself about unused capacity, auto-scaling, or load balancing.
