Haskell with Nix - 1 Day

Online class: Participate from anywhere.

Target Audience

You are already convinced of the benefits of Haskell and Nix but find the integration and learning curve daunting. The documentation provides information but lacks the practical, step-by-step guidance you need. You are about to use Haskell with Nix in a real-life project and want to ensure you do it correctly.

Master the integration of Haskell and Nix in just one day! We’ll guide you through essential practices, ensuring a reproducible setup and robust development environment, so you can confidently tackle complex projects and streamline your workflow.

Class Goals

In this class, you will learn how to setup a Nix based development environment for Haskell. Furthermore, you will know common pitfalls that occur when migrating an existing development environment to a Nix based one.
