Implementation Reference

• src/clients/drug-name-client.ts:35-80 (handler)

  The core handler implementation for searching drug names, including API request construction and pagination handling.

  async searchDrugNamesAdvanced(params: DrugNameSearchParams = {}): Promise<PaginatedDrugNameResponse> {
    const { page = 1, pageSize = 100, ...searchParams } = params;
    
    validatePaginationParams(page, pageSize, 100);
  
    try {
      const queryParams: any = {
        page,
        pagesize: Math.min(pageSize, 100), // API max is 100
      };
  
      // Add search filters
      if (searchParams.drug_name) queryParams.drug_name = searchParams.drug_name;
      if (searchParams.name_type) queryParams.name_type = searchParams.name_type;
      if (searchParams.manufacturer) queryParams.manufacturer = searchParams.manufacturer;
  
      const response = await this.client.get("/drugnames.json", {
        params: queryParams,
      });
  
      if (
        response.data &&
        response.data.data &&
        Array.isArray(response.data.data)
      ) {
        const drugNames = response.data.data.map((item: any) => ({
          drugName: item.drug_name,
          routeOfAdministration: item.route_of_administration,
          activeIngredient: item.active_ingredient,
        }));
  
        // Extract pagination metadata from API response
        const totalResults = response.data.metadata?.total_elements || drugNames.length;
        const totalPages = Math.ceil(totalResults / pageSize);
  
        return {
          data: drugNames,
          pagination: {
            page,
            pageSize,
            totalResults,
            totalPages,
            hasNextPage: page < totalPages,
            hasPreviousPage: page > 1,
          },
        };
