Implementation Reference

• src/clients/spl-client.ts:364-390 (handler)

  Implementation of the `getSPLMedia` method in `SPLClient` which fetches media links for a drug from DailyMed.

  async getSPLMedia(setId: string): Promise<any[]> {
    if (!setId || typeof setId !== "string") {
      throw new Error("Valid SET ID is required");
    }
  
    try {
      const response = await this.client.get(`/spls/${setId}/media.json`);
  
      if (
        response.data &&
        response.data.data &&
        Array.isArray(response.data.data)
      ) {
        return response.data.data.map((item: any) => ({
          url: item.url,
          type: item.type,
          name: item.name,
        }));
      } else {
        throw new Error("Unexpected response structure for SPL media");
      }
    } catch (error) {
      throw new Error(
        `Failed to fetch SPL media: ${error instanceof Error ? error.message : "Unknown error"}`,
      );
    }
  }
