Today, 2025-07-09, at 1830 UTC (11:30 am PDT, 2:30 pm EDT, 7:30 pm GMT, 20:30 CET, …) we are streaming the 46th episode of the Haskell Unfolder live on YouTube.
Developing an application from scratch (Haskell Unfolder #46)
In this episode targeted at beginners, we show the end-to-end application development process, starting from an empty directory. We’ll consider package configuration, taking advantage of editor integration, how to deal with dependencies, organizing code into modules, and parsing command line arguments. We will use this to write a simple but useful application.
About the Haskell Unfolder
The Haskell Unfolder is a YouTube series about all things Haskell hosted by Edsko de Vries and Andres Löh, with episodes appearing approximately every two weeks. All episodes are live-streamed, and we try to respond to audience questions. All episodes are also available as recordings afterwards.
We have a GitHub repository with code samples from the episodes.
And we have a public Google calendar (also available as ICal) listing the planned schedule.
There’s now also a web shop where you can buy t-shirts and mugs (and potentially in the future other items) with the Haskell Unfolder logo.
