// Importing libraries here
import fetch from 'node-fetch';
// Define the ID of any recipe here
const id = '{{RECIPE_ID}}';
// Define endpoint URL here
const endpointUrl = new URL(`https://api.spoonacular.com/recipes/${id}/nutritionLabel`);
// Define API key here
const apiKey = '{{API_KEY}}';
// Define Header Parameters here
const headerParameters = {
  'x-api-key': apiKey,
  'content-type': 'text/html',
};
// Define Query Parameters here
const queryParameters = new URLSearchParams({
  defaultCss: true,
});
// Setting API call options
const endpointOptions = {
  method: 'GET',
  headers: headerParameters,
};
// Function to make API call
async function recipeNutritionLabelWidget(url, options) {
  try {
    // Using the fetch method to make an API call to Spoonacular 
    const response = await fetch(url, options);
    // Custom function for printing the API response
    printResponse(response);
  } catch (error) {
    // Custom function for printing the error message
    printError(error);
  }
}
// Attaching query parameters to the endpoint URL
endpointUrl.search = queryParameters;
// Calling function to make API call
recipeNutritionLabelWidget(endpointUrl, endpointOptions);

Take a look at the following explanation of the code above:

  • Line 5: We set and store the ID of a recipe for which we want to fetch the label widget.

  • Line 8: We use the endpoint URL /recipes/{id}/nutritionLabel to fetch the Spoonacular widget that displays a nutritional label.

  • Line 11: We assign the API key here to the apiKey variable.

  • Lines 14–17: We define the header parameters for the API call. We can modify or add parameters using the headerParameters variable.

    • Line 15: We pass the apiKey variable to the x-api-key header parameter.

    • Line 16: We need to set the content-type header parameter to text/html.

  • Lines 20–22: We define the query parameters for the API call. We can modify or add parameters using the queryParameters variable.
