• Using Either/Result in TypeScript for Error Handling
  1 project | dev.to | 3 Oct 2025

  When we discuss the Either type in TypeScript, the fp-ts library empowers developers to build pure functional programming apps, using key abstractions from languages like Haskell, PureScript, and Scala.

• Why Next.js Apps Struggle at Scale (And How Feature Layers Solve It)
  3 projects | dev.to | 3 May 2025

  Functional programming plays a crucial role in our feature layer, providing a structured and efficient approach to managing connections between different layers of our system. Beyond its traditional benefits, functional programming enables robust error handling and manipulation throughout the application. By following to functional principles, we ensure that each process within our system is handled independently and comprehensively, enhancing clarity and maintainability. Through functional programming, we can easily propagate return types across layers, enabling clear communication and transparent data flow. This approach not only enhances code organization and readability but also promote modularization and decoupling, leading to a more maintainable and scalable architecture. We leverage the fp-ts library for functional programming in TypeScript, which provides a rich set of abstractions and utilities for working with functional concepts.

  In addition to our testing strategy, we ensure that each service in our modules—whether public or private—follows a functional programming style using the fp-ts library.

• From a Lorry Driver to Ruby on Rails Developer at 38

  I think it’s great that functional programming is making its way into traditional imperative languages - even JavaScript (I recently came across https://gcanti.github.io/fp-ts/ as a pretty extreme example)

  Elixir/Erlang has function-level pattern matching, which I really like. I’ve yet to see it anywhere else, though my understanding is it came from Prolog.

• Type-Safe Printf() in TypeScript
  4 projects | news.ycombinator.com | 24 Mar 2024

  While I certainly agree, I've found that this is often an indication of too-complex an architecture, and a fundamental re-think being necessary. I've had projects that depend on [fp-ts], which end up incredibly generic-heavy, but still make it entirely through a typecheck(not build- typescript's just worse at that than other tools like esbuild) in seconds-at-worse.

  Obviously depends on your organization/project/application, but I do like these things as complexity-smells.

• Introducing fp-utils a functional utility library for Deno / Node
  2 projects | /r/Deno | 10 Dec 2023

  Unlike more comprehensive functional libraries like fp-ts, each module can be imported and resolved separately. If you just need options, simply add the option module and you're good to go.

• Blog post: graphs and monads with Typescript
  2 projects | /r/typescript | 7 Dec 2023

  While it's quite abstract, I believe it may be useful to those of you who is interested to learn more about functional programming [in Typescript] and also get more intuition on diverse programming ideas. I use fp-ts as a functional programming library there.
