Maybe refactor type map #67

Description

@darthmaim

Instead of having all those enums with endpoints, maybe do something like this instead:

type Item = { id: number; name: string; };

type EndpointMap<Schema> = {
  '/v2/build': {
    type: { build: string }
  },
  '/v2/items': {
    bulk: {
      id: number
      type: Item
    }
  },
  '/v2/quaggans': {
    bulk: {
      id: string
      type: { id: string; name: string; }
      all: true
    }
  }
}

type GetEndpointsMatching<Schema, T> = { [X in keyof EndpointMap<Schema>]: EndpointMap<Schema>[X] extends T ? X: never }[keyof EndpointMap<Schema>]

type SimpleEndpoints<Schema> = GetEndpointsMatching<Schema, { type: any }>
type BulkEndpoints<Schema> = GetEndpointsMatching<Schema, { bulk: any }>

type BulkEndpointSingleUrlMap<Schema> = { [Endpoint in BulkEndpoints<Schema> as `${Endpoint}/${EndpointMap<Schema>[Endpoint]['bulk']['id']}` | `${Endpoint}?id=${EndpointMap<Schema>[Endpoint]['bulk']['id']}`]: Endpoint }
type BulkEndpointAllUrlMap<Schema> = { [Endpoint in BulkEndpoints<Schema> as `${Endpoint}?ids=all`]: EndpointMap<Schema>[Endpoint]['bulk'] extends { all: true } ? Endpoint : never }
type BulkEndpointManyUrlMap<Schema> = { [Endpoint in BulkEndpoints<Schema> as `${Endpoint}?ids=${string}`]: Endpoint }

type EndpointFromUrl<Url, Schema> =
  Url extends SimpleEndpoints<Schema> ? { endpoint: Url, type: EndpointMap<Schema>[Url]['type'] } :
  Url extends BulkEndpoints<Schema> ? { endpoint: Url, type: EndpointMap<Schema>[Url]['bulk']['id'][] } :
  Url extends keyof BulkEndpointSingleUrlMap<Schema> ? { endpoint: BulkEndpointSingleUrlMap<Schema>[Url], type: EndpointMap<Schema>[BulkEndpointSingleUrlMap<Schema>[Url]]['bulk']['type'] } :
  Url extends keyof BulkEndpointAllUrlMap<Schema> ? { endpoint: BulkEndpointAllUrlMap<Schema>[Url], type: EndpointMap<Schema>[BulkEndpointAllUrlMap<Schema>[Url]]['bulk']['type'][] } :
  Url extends keyof BulkEndpointManyUrlMap<Schema> ? { endpoint: BulkEndpointManyUrlMap<Schema>[Url], type: EndpointMap<Schema>[BulkEndpointManyUrlMap<Schema>[Url]]['bulk']['type'][] } :
  { endpoint: unknown, type: unknown };

type EndpointType<Url, Schema> = EndpointFromUrl<Url, Schema>['type'];
type GetEndpointDefinition<Url, Schema> = EndpointFromUrl<Url, Schema>['endpoint'] extends keyof EndpointMap<Schema> ? EndpointMap<Schema>[EndpointFromUrl<Url, Schema>['endpoint']] : unknown;
