Bix.Bun

Bix

Bix which can be found in src/Bix is an F# microframework built on top of Bun.serve although the name is just a codename for now (until I decide it's good to go), this microframework is heavily inspired by Giraffe, and Saturn frameworks from F# land so if you have ever used that server model then Bix will feel fairly similar, I plan to add a saturn like router eventually

Bix.Bun

Bix.Bun exposes a bun.sh specific request handler, and other http handlers that may contain Bun specific APIs like Bun.file to read files

Check the sample at src/Bix.Bun.Sample/Program.fs

Bix.Deno

Bix.Deno exposes a deno specific request handler, and other http handlers that may contain Bun specific APIs like Deno.open to read files

Check the sample at src/Bix.Deno.Sample/Program.fs

Note: When Working with deno, you need to have the following fields in your import map

{
  "imports": {
    "urlpattern-polyfill": "https://cdn.skypack.dev/pin/[email protected]/mode=imports,min/optimized/urlpattern-polyfill.js",
    "http": "https://deno.land/[email protected]/http/server.ts"
  }
}

This is to ensure bare imports within Bix.Browser.Types and Bix.Deno work just fine.

Development

This project is developed with VSCode in Linux/Windows/WSL but either rider, and visual studio should work just fine.

Requirements

• .NET6 and above - https://get.dot.net
• Bun - bun.sh - (in case of running bun)
• Deno - deno - (in case of running deno)

Try the sample

if you have bun installed along deno the simplest way to run the samples is

• bun start
• bun start:deno

both commands will restore the projects and run fable, bun/deno in watch mode

Bun

After installing .NET + Bun just run

bun start on your terminal and it should just work

Deno

After installing .NET + Bun just run

dotnet tool restore && \
dotnet fable watch src/Bix.Deno.Sample -s -o dist/Bix.Deno.Sample --run deno run -A ./dist/Bix.Deno.Sample/Program.js`
