Let’s build a Cloudflare Worker with WebAssembly and Haskell

This is a guest post by Cristhian Motoche of Stack Builders.

At Stack Builders, we believe that Haskell’s system of expressive static types offers many benefits to the software industry and the world-wide community that depends on our services. In order to fully realize these benefits, it is necessary to have proper training and access to an ecosystem that allows for reliable deployment of services. In exploring the tools that help us run our systems based on Haskell, our developer Cristhian Motoche has created a tutorial that shows how to compile Haskell to WebAssembly using Asterius for deployment on Cloudflare.

What is a Cloudflare Worker?

Cloudflare Workers is a serverless platform that allows us to run our code on the edge of the Cloudflare infrastructure. It's built on Google V8, so it’s possible to write functionalities in JavaScript or any other language that targets WebAssembly.

WebAssembly is a portable binary instruction format that can be executed fast in a memory-safe sandboxed environment. For this reason, it’s especially useful for tasks that need to perform resource-demanding and self-contained operations.

Why use Haskell to target WebAssembly?

Haskell is a pure functional languages that can target WebAssembly. As such, It helps developers Continue reading
