swagger-to-ts considers components mandatory

[henhal]

When running swagger-to-ts on a specification without components, it immediately fails.
However, components is an optional part of the api schema and I can think of at least two scenarios where it would not be present:

1. All schemas are inline in paths
2. All schemas are put in separate file(s) such as schemas.yml

My specifications are quite large and I tend to split them up into separate files as per 2). This means that operations reference schemas such as {$ref: './schemas/foo.yml#/Foo'}.
Neither of these two approaches seem to work with swagger-to-ts since it requires components to be present (and, I assume, also ignores any schemas outside of components)?

1. Would it be possible to invoke swagger-to-ts with a raw schema file, i.e., one that simply contains the schemas instead of requiring a full OpenAPI document?
2. Would it be possible to properly support OpenAPI documents without components? It should be possible to fetch all externally referenced schemas using standard json-ref-parser etc?

I encountered the same problem with OpenAPI schema with `paths` on top level.

{
  "openapi": "3.0.2",
  "paths": {
    "/v1/crowd/users/": {
      "get": {
        "operationId": "listUsers",
        "description": "",
        "parameters": [],
        "responses": {
          "200": {
            "content": {
              "application/json": {
                "schema": {
                  "type": "array",

                      "first_name": {
                        "type": "string",
                        "maxLength": 150
                      },
                      "last_name": {
                        "type": "string",
                        "maxLength": 150
                      },
                      "locale": {
                        "type": "string",

                        "readOnly": true

                      "username"
                    ]
                  }

            },
            "description": ""
          }
        }
      },

What's the status of this issue and #236? Is there any work requiring external help to make schemas without components work?

Just merged #236, so this will go out with the next release!
