FSharp.SystemTextJson.Swagger

Swagger settings for FSharp.SystemTextJson. Still experimantal

Usage

Only replace AddSwaggerGen with AddSwaggerForSystemTextJson

let builder =  WebApplication.CreateBuilder(args)
let fsOptions = JsonFSharpOptions() // setup options here 
//setup usage of JsonFSharpConverter                
builder.Services.AddControllers()
                    .AddJsonOptions(fun opts ->
                        opts.JsonSerializerOptions.Converters.Add(JsonFSharpConverter(fsOptions))) 
// setup usage of SwaggerForSystemTextJson - use instead AddSwaggerGen 
builder.Services.AddSwaggerForSystemTextJson(fsOptions)

let app = builder.Build()

if (app.Environment.IsDevelopment()) then
      app.UseSwagger() |> ignore
      app.UseSwaggerUI() |> ignore

What works

Not everything is now implemented. Some things works with limitations

Records

• Works
• All properties are required except of Skippable
• Option properties are set as nullable

Tuples

• Works
• Evaluates to array of composed type
• Array has length limits to tuple length
• Composed type is made as oneOf keyType and valueType
• Warning - request generated by this schema could be invalid.

Collections

• List and Set: works
• Maps
  • with string keys - works
  • with boxed string - works
  • other - works
  • Evaluates to array of Tuples.
  • Warning - request generated by this schema could be invalid

Unions

• Almost every setup combinations works
• Still experimental
