How can we obtain the response headers?

From what I can see, only data and error is returned.

How can we access the response headers?

Workaround for now - use the onResponse hook:

  onResponse: async (context) => {
    const json = await context.response.clone().json();
    const headersObj: Record<string, string> = {};
    context.response.headers.forEach((v, k) => {
      headersObj[k] = v;
    });
    return new Response(
      JSON.stringify({
        json,
        headers: headersObj,
      }),
      {
        ...context.response,
      }
    );
  },

Then your data object will contain json and headers as keys.

If using output, you will need to account for this, e.g. with a helper function:

const makeResponseSchema = <T extends v.GenericSchema>(outputSchema: T) => {
  return v.object({
    json: outputSchema,
    headers: v.record(v.string(), v.string()),
  });
};

Used as follows:

    "/customers": {
      method: "get",
      query: v.object({
        page: v.optional(v.number()),
        from: v.optional(v.string()),
        to: v.optional(v.string()),
        date_field: v.optional(v.string()),
      }),
      output: makeResponseSchema(v.array(Customer)),
    },
