Add default number type configuration

[PetrKubes97]

Hi, some time back I've asked about default number types, but unfortunately the issue was closed as stale - #1408. I went ahead and implemented it anyway as it is super useful for my project. I think it's quite useful, as double as the default number type isn't suitable, if the backend uses for example number ids for entities. The amount of annotation is then just too damn high.

I wasn't sure how to write proper test for this, as I could find any configuration tests.

Potential Problems With The Approach

Test plan

Is there any way to escape from having integers when I have a ts type number?

IMO that has to be there otherwise it's simpler to just use a custom template.

[PetrKubes97]

Not sure what you mean by "escape from having integers when I have a ts type number". When a ts type is number, tsoa defaults to

type: number
format: double

Only if I set the default to integer, it switches to

type: integer,
format: int32,

The default behaviour is unchanged.

So assume I want to have a double field now:

interface T {
  id: number // this is now fine without @isInt
  amount: number // <--- how do I make this a double ?
}

[PetrKubes97]

There is a @isDouble annotation already, but it is not documented. That might be the source of confusion. I'm using it in my project and works as expected.

Makes sense, I wasn't sure if that could override the integer though.
That would certainly be a useful test then.
You can run the Metadata generator directly, i.e. in the metadata tests (Link), or, if you want to test e2e, start from the prepare.ts:

@WoH Hi, sorry for the delay. I've added the tests. Had some troubles with different formatting settings, .editorconfig might need some love.
