paramsSerializerOptions: arrayFormat does not seems to work.

[omarkhatibco]

Hello,

I'm trying to use arrayFormat but it does not seems to work, as in the docs

paramsSerializerOptions: {
    qs: {
        arrayFormat: 'brackets',
    },
},

I'm not sure it's a bug since there is no qs library installed anyway. does this option only works if axios is used?

Update: I just tried to provide a custom params serializer function, it's not used in the generated code and all the code are using URLSearchParams

I think we need much better documentation: https://orval.dev/reference/configuration/output#paramsserializeroptions

I have no idea what qs means or what the options for arrayFormat are! Or even any explanaton on what paramsserializeroptions is used for or what problem it solves.

Yes, it seems like this is only supported for axios currently..

@AllieJonsson these docs definitely need improving as I looked at it and it tells me absolutely nothing about this feature, what its for, what the values mean, Axios only etc?

[AllieJonsson]

I agree! I can try to both improve the docs and make this work with fetch, its quite a cool feature!
qs is a npm package that stringifies query parameters from an object. E.g.

{
  Foo: {
    Bar: "baz"
  }
}

Could become
?Foo[Bar]=baz
