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.

Migration of a Dynamic Website to a Static Website
Instead, what I ended up doing is utilizing AngleSharp for transforming the existing (dynamic) websites into static files. I've stored them on disk and made them ready to be served statically.

What do .NET devs use for web scraping these days?
AngleSharp
-
School Web scraping
Read and understand the HTML DOM with something like this https://anglesharp.github.io/
- Text editor library/HTML parser options for blogging app
-
Powershell/HTML: Apply color to HTML table based on results
Personally, if that script I wrote did need to be used on Core I probably would have compiled AngleSharp, loaded the HTML Parser DLL into the script, and used that.

C# Web Scraper to check a sent Form
Now, assuming you have to scrape, C# does have two decent scraping libraries: AngleSharp and Html Agility Pack. I personally prefer AngleSharp.
-
Tell me your common tasks!
I would love a blog post or even a series of them about scraping local HTML files with either AngleSharp or HTMLAgilityPack.

How can I grab onto the html class name of a string that contains html, using c#?
If you want a cleaner and modern alternative to HtmlAgilityPack then I'd suggest https://github.com/AngleSharp/AngleSharp

The combined power of F# and C#
Giraffe is another interesting one to explore: https://giraffe.wiki/
Giraffe is nice because it is itself built "just" as ASP.NET Core Middleware so it plays a bit more nicely than Suave with a mixed stack of C#-defined Middleware.
It's more likely you accidentally fall back into just translating C# patterns to non-idiomatic F# with Giraffe, but it's also nicer when in that case of needing to live in both worlds and use a mixture of libraries built for C# ASP.NET projects.

There are also some F# frameworks built on top of ASP.NET core like https://giraffe.wiki

-
Is there any advantage to using F# instead of C#?
If you have an interest in F#, I highly recommend diving in because (1) it has a ton of things you might learn to appreciate in C#; (2) it has things C# cannot have. I do like some of the suggestions people have made regarding mixing your code bases, but I'll also say that building, say, endpoint routing in Giraffe is (to repeat myself) easy, simple, and elegant.

Targeting Node, Bun and Deno With F#
Bix is a micro-framework designed with F# in mind and that runs on both Deno and Bun! and in theory it also should even run in a service worker! (intercepting fetch requests) although I haven't tested that yet, it offers a general purpose handler that coupled with a set of route definitions it can bring a Giraffe/Saturn like framework to life in JavaScript runtimes which is incredibly awesome! useful? maybe not š , but awesome indeed. Let's see some code for it

If you were to create a Web API today from scratch how would you do it ?
Backend: Most likely it would be a toss between https://saturnframework.org or https://giraffe.wiki. They both combins the extremely good type system in F# combined with the ease of a minimal API.

Is it possible to run C# asp.net core MVC and f# giraffe in a single solution
I was wondering if its possible to simultaneously run a C# core MVC project in combination with https://github.com/giraffe-fsharp/Giraffe

Overriding JSON serializer in Giraffe
By default Giraffe, the framework which I use as a web server, uses Newtonsoft.Json to serialize results to JSON. However, for discriminated union, it generates quite a lot of JSON so I've switched to System.Text.Json which is built into newer versions of .Net Core. In combination with FSharp.SystemTextJson package allows serializing discriminated unions more gracefully. All we need is to decorate Branch type with JsonFSharpConverter(JsonUnionEncoding.BareFieldlessTags) attribute.

Introducing Giraffe.Htmx
Giraffe is a library that sits atop ASP.NET Core and allows developers to build web applications in a functional style; dotnet new giraffe is literally my starting point when I begin a new web application project. (Rather than write three more sentences filled with effusive praise, Iāll just leave it at that; itās great.) It also provides a view engine (that builds upon Suaveās āexperimentalā view engine) which uses an F# DSL to define HTML in a strongly-typed way. It has been incredibly efficient for a while, but with .NETās work over the past two releases at improving performance, and Giraffeās adoption of those techniques, it is lightning fast.

Show HN: F# web server in 3-4 lines of code
Wrapping ASP.NET Core to be easier and more idiomatic with F# seems to be a common domain. Out of curiosity, did you look at any existing projects? If so, what was lacking from them that made you decide to write WebFrame?
