Expose the *Json settings types in the `@coderline/alphatab` package

Is there an existing issue for this?

Current Behavior

I've just installed the latest alpha (1.4.0-alpha.1080 at this point), and I'm really happy you included the JSON version of the configuration types.

The issue I'm facing, is that the types are not exposed. So while type checking/autocomplete works fine for inline api-creation:

new AlphaTabApi(dom, { ... })

The type itself cannot be reused without extracting it first:

import { AlphaTabApi } from '@coderline/alphatab'

// Get the constructor type which is a union
type Settings = ConstructorParameters<typeof AlphaTabApi>[1]
// Extract the JSON type with some ts magic
type ExtractJsonType<T> = T extends { fillFromJson: any } ? never : T
type SettingsJson = ExtractJsonType<Settings>

// Extract the necessary types from the Json type
type CoreSettingsJson = Exclude<SettingsJson['core'], undefined>
type PlayerSettingsJson = Exclude<SettingsJson['player'], undefined>
type DisplaySettingsJson = Exclude<SettingsJson['display'], undefined>

Expected Behavior

import { SettingsJson, CoreSettingsJson, DisplaySettingsJson, NotationSettingsJson, ImporterSettingsJson, PlayerSettingsJson } from '@coderline/alphatab'

or at least:

import { SettingsJson } from '@coderline/alphatab'

Very good point. For the proper use they should be exposed.

This works perfectly in 1.4.0-alpha.1085 now, thank you!

import { json } from '@coderline/alphatab'

const display: json.DisplaySettingsJson = {...}
const player: json.PlayerSettingsJson = {...}
const core: json.CoreSettingsJson = {...}

const config: json.SettingsJson = { core, display, player }
