Paweł Szulc demonstrates how to build flexible, extensible, and testable software using Haskell, polysemy, and servant.
In this Lambda World 2019 presentation, Paweł Szulc shows the benefit of programming with Haskell. Full Presentation Description: Developers interested in seeing Haskell being used as a general programming language. Engineers hoping to see Haskell as an environment in which one can quickly and effectively iterate between requirements, design and running, executable code - providing value to the business with an immediate feedback loop. Developers eager to see how they can rapidly create software that is flexible to changes, extensible and testable. Pre-requirements: basic understanding of Haskell syntax (functions, composition, do-notation, type classes) basic FP building blocks: functor, monad (optionally) some previous exposure to free monads (optionally) scars and war stories of using tagless final in Haskell Tech stack we will explore: polysemy servant ------ Follow: -twitter.com/lambda_world -twitter.com/47deg -twitter.com/rabbitonweb Visit: -47deg.com/events for more details -lambda.worldWhy it's here

Is this the correct way of using Polysemy inside a Servant application?
After watching yet another Paweł Szulc's talk on Polysemy, I decided that it was time to use it, and since I can only think of rest APIs I'm trying to build one using Servant, where the handlers themselves are built using Polysemy.
This itself was inpired by another talk by Szulk.
I have succesfully built a workgin PoC. In doing so I found myself wondering if I was doing something wrong, since this was my first time for both Polysemy and Servant, so I'm here to ask you to point me to the right direction.
What follow is a brief summary of what I did. The full code can be found in this gihub repo. Questions are at…

One of the most "idiomatic" examples of BLOBA is this one I think. The title of the presentation is "Painless software development with Haskell" for a good reason

These are two eloquent presentations
