@StratusFearMe21 why did you need to add this piece? I see the test fails without it, but I'm concerned about tying internals to OpenAPI/Swagger like this

That piece is so that the regression test can set resolvedInput.path on each input schema without the type of the resolvedInput being set to 'url'. This is so that when the test calls bundleMany on the input, the prefixes on the output securitySchemas is predictable.

I'm not sure I understand, is this just to satisfy the test suite? Or is this needed for a real world usage?

I put it there to satisfy the test suite, but if you were using this package in the real world, passing multiple JSON objects to bundleMany would be broken without this change since both schemas would resolve to the same path . Either url.cwd() or 'schema'.

Might be better to handle that as a separate issue. I'm also concerned about this package, it feels like it's doing too much too poorly because I'm sure there are other similar edge cases we just didn't run into yet

Why $id on a schema object is essential to bundleMany

Line 45 is in getResolvedInput, which is called by parseMany (line 250) — the first step of bundleMany. The critical logic is at lines 44-59:

When a JSON object (not a file path or URL) is passed as an input, resolvedInput.path starts as '' (line 30). Without a $id, the path stays empty, and line 62-64 kicks in:

if (resolvedInput.type !== 'json') {
  resolvedInput.path = url.resolve(url.cwd(), resolvedInput.path);
}

This means a schema without $id falls through entirely — type stays 'url', no path is set, and it gets resolved against url.cwd() (the current working directory).

But when the schema does have $id (and is an OpenAPI/Swagger document), lines 51-52 set resolvedInput.path to the $id value and type to 'json'. This is critical for bundleMany because:

  1. parseMany (line 295) stores this path in this.schemaManySources[i]:

    this.schemaManySources.push(path && path.length ? path : url.cwd());

  2. mergeMany (line 489-490) uses that source path to compute the prefix used for namespacing all components:

    const sourcePath = this.schemaManySources[i] || `multi://input/${i + 1}`;
const prefix = baseName(sourcePath);

  3. That prefix is then used to rename all components (schemas, parameters, securitySchemes, etc.) to avoid collisions between the multiple inputs:

    const newName = `${prefix}_${name}`;  // e.g., "petstore_Pet" instead of "Pet"

  4. It's also used to rewrite $ref pointers (line 512), prefix operation IDs (line 479), prefix tag names (line 522), and resolve relative external references (line 463).

Without $id, an inline schema object would get path = '', which would make baseName return a generic name (or fall back to the CWD-derived path), causing unpredictable or colliding prefixes when multiple JSON objects are bundled together. The $id provides a stable, unique identity for each inline schema, enabling the entire namespacing and reference-rewriting machinery of bundleMany to work correctly.')

// when schema id has defined an URL should use that hostname to request the references,
// instead of using the current page URL
const { hostname, protocol } = new URL(pathOrUrlOrSchema.$id as string);

Oops, I didn't mean to keep that in this PR, that's my mistake.

It fixes another bug where if the path on the resolvedInput is set to url.cwd(), because that function always puts a trailing slash at the end of the path, splitting the path /foo/bar/baz/ for example would return ['foo', 'bar', 'baz', '']. Because the last element in parts is empty, baseName would just return 'schema' instead of the last component of the path.

Do you want to open a separate pull request for that?
