How to get TS Type from Adonis schema?

[cawa-93]

I would like to somehow get the type of interface created by schema. Something like this:

const newPostSchema = schema.create({
  title: schema.string(),
  kind: schema.enum(['article', 'note'] as const),
})

type newPostType = typeof newPostSchema

This is not needed for validation, but to improve DX and intellisense:

function preparePost(): newPostType {
  return {
    title: 'foo',
    kind: 'bar' // TS2322: Type '"bar"' is not assignable to type '"article" | "note"'.
  }
}

Hey @cawa-93! 👋🏻

You can export it using the following.

export type NewPostValidatorData = NewPostValidator['schema']['props']

class NewPostValidator {
  // ...
}
