The fsi-web-minimal .NET template can be used to generate F# minimal API apps using only .fsx scripts, without a full .fsproj, but only with .fsx files.
An utility html dsl view engine Feliz.ViewEngine is provided as a dependency, but can be removed or replaced with other view engines.
Waiting for the official F# mascotte announcement yet.
cd working/content
dotnet new install .
dotnet new fsi-web-minimal
you should get a directory structure like the one below (same as test folder).
run the download script
dotnet fsi downloadScripts.fsx
then run
dotnet fsi generate-sdk-references.fsx
then to run the app make sure you have installed NET8 SDK LTS,
then run to start the server, listening to port 5000.
dotnet fsi script.fsx
navigate to http://localhost:5000/swagger to check the OpenApi spec
to live test the api, download the openapi spec while your app is running, for convenience the test.fsx script includes also such utility function, remember to run this script your server must be running and serving the openapi/swagger metadata, it won't work if you didn't start your script yet.
dotnet fsi test.fsx --update-openapi
then normally run the test dotnet fsi test.fsx
the test is performed against the OpenApi contract using the awesome SwaggerProvider you should see in your server terminal window the endpoints being hit, and you will get a print result for your test endpoint invocation.
TBD, is possible obviously to run these commands in DOCKER just using the microsoft dotnet-sdk image, that also includes dotnet fsi as command.
The convenience of a single script app makes it possible for F# to shine as a great language for microservices. All well isolated and testable, from the public openapi a clear contract specification, a monorepo or many repos you can decide for your own.
