Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
FsToolkit.ErrorHandling
-
Type setup for effortless error handling with the Result type
Isn't this similar to what https://github.com/demystifyfp/FsToolkit.ErrorHandling does?
-
It seems like I'm forced to make this choice at least once a day
I do think at least some of FSToolkit.ErrorHandling should be part of the core library though, it has nearly everything you could want for using these types.
-
How do I compose the functions with the following signatures?
I'm having trouble following exactly what you're trying to do, but it would probably be easier if you used the builtin Result type in conjunction with FsToolkit.ErrorHandling. The library provides many useful combinators as well as a result, option, and resultOption computation expression.

Dealing with workflows in F#
Also shout out to the wonderful FsToolkit.ErrorHandling library, it simplifies working with these so much.

F# 6 Hopes and kind of a rant
Monad stacks, most commonly Async>, require a lot of boilerplate to deal with or using something like https://github.com/demystifyfp/FsToolkit.ErrorHandling . Which is fine, but it causes dependency mismatches between libs or type mismatches as everyone is implementing their own. A language solution would be nice...

Say hello to "block" - the recently finalized name for the upcoming immutable array type
This library is nice: https://github.com/demystifyfp/FsToolkit.ErrorHandling

Dada, an Experiement by the Creators of Rust
This conversation could be referring to https://fable.io/
Other than that, the question is indeed strange and I agree with your statements.

Exploring a foreign F# codebase
NOTE: For larger codebases with more history it is likely that the Program.fs file will have a lot of orchestration and logic as well. given that it is often where everything clashes and starts, for example the Fable Entrypoint is in Entry.fs and it contains a lot of code. The best you can do always is to start at the bottom of the file and work your way up. Remember: Everything at the bottom uses what has already been defined at the top so there are no circular dependencies or random functions/types at the bottom that can trip you off, everything comes from the top!

Revisiting WASM for F#
I am a big fan of going with web components + plain (build-less) javascript whenever possible, so it is not surprising that I often favor things like the Fable Compiler, where I can target my F# code directly to javascript and be as close to the native JS experience as possible, both for interop concerns and for ecosystem integration.

A new F# compiler feature: graph-based type-checking
Fable compiler - https://fable.io/
The F# community is very friendly (these sub-communities as well), and they have plenty of good issues/opportunities to contribute OSS work to across any skill level.
Phosphor isn't hiring right now, but we expect to begin a search for FE/interface engineers over the next few month. Email [email protected] for anyone interested.

Building React Components Using Unions in TypeScript
Naturally Iโd recommend using a better language such as ReScript or Elm or PureScript or F#โs Fable + Elmish, but โReactโ is the king right now and people perceive TypeScript as โless riskyโ for jobs/hiring, so here we are.

Dart 3.1 and a retrospective on functional style programming in Dart
Stuff like this: https://github.com/fable-compiler/Fable/issues/1822
It just seems like an incredibly ambitious project that appears to have very little equal but is mainly worked on by a handful of people but no corporate backing. I get the feeling that if you want to use it, you'll either be the only one doing what you're doing or among just a few people. I already use F# and feel this way about the core language itself.

Elixir โ Why the dot (when calling anonymous functions)?
F# is also part of the OCaml family, has a great to-JS transpiler (https://fable.io/) and F# code can also be used in .NET projects.

URGENT HELP NEEDED! Should I learn C#, ASP.NET and the new MAUI framework?
I have heard many good things about https://fable.io/ Fable converts F# code to JavaScript. There are currently 407 packages available for interacting with existing JavaScript packages and frameworks.
What are some alternatives?
ply - High performance System.Threading.(Value)Task computation expressions for F#
rescript-compiler - The compiler for ReScript.
visualfsharp - The Visual F# compiler and tools
Sutil - Lightweight front-end framework for F# / Fable. No dependencies.
VisualFSharp - The F# compiler, F# core library, F# language service, and F# tooling integration for Visual Studio
ClojureCLR - A port of Clojure to the CLR, part of the Clojure project
Optional - A robust option type for C#
Roslyn - The Roslyn .NET compiler provides C# and Visual Basic languages with rich code analysis APIs.
fslang-suggestions - The place to make suggestions, discuss and vote on F# language and core library features
Feliz - A fresh retake of the React API in Fable and a collection of high-quality components to build React applications in F#, optimized for happiness
haxe - Haxe - The Cross-Platform Toolkit
Roslyn-linq-rewrite - Compiles C# code by first rewriting the syntax trees of LINQ expressions using plain procedural code, minimizing allocations and dynamic dispatch.
