Pseudocode for Fetching Recipes from an API

Overview

This pseudocode outlines the steps to fetch recipes from an API. It includes making an API request, handling responses, and processing recipe data.

Pseudocode

BEGIN FetchRecipesFromAPI

    // Step 1: Define API endpoint and necessary variables
    SET apiEndpoint TO "https://example.com/api/recipes"
    SET apiKey TO "your_api_key"
    SET recipes TO EMPTY_LIST

    // Step 2: Make an API request to get recipes
    FUNCTION fetchRecipes(apiEndpoint, apiKey)
        SET headers TO {"Authorization": "Bearer " + apiKey}
        SET response TO httpGet(apiEndpoint, headers)

        // Step 3: Handle API response
        IF response.status_code == 200 THEN
            SET recipesData TO response.data
            // Step 4: Process the recipe data
            recipes = processRecipes(recipesData)
        ELSE
            DISPLAY "Error: Unable to fetch recipes. Status code: " + response.status_code

    END_FUNCTION

    // Sub-function to process the recipe data
    FUNCTION processRecipes(recipesData)
        SET processedRecipes TO EMPTY_LIST
        
        FOR EACH recipe IN recipesData
            SET recipeDetails TO {
                "name": recipe["name"],
                "ingredients": recipe["ingredients"],
                "instructions": recipe["instructions"]
            }
            ADD recipeDetails TO processedRecipes
        END_FOR

        RETURN processedRecipes
    END_FUNCTION

    // Step 5: Display recipes
    FUNCTION displayRecipes(recipes)
        FOR EACH recipe IN recipes
            DISPLAY "Recipe Name: " + recipe["name"]
            DISPLAY "Ingredients: " + JOIN(recipe["ingredients"], ", ")
            DISPLAY "Instructions: " + recipe["instructions"]
            DISPLAY "--------------------------"
        END_FOR
    END_FUNCTION

    // Execute the functions
    CALL fetchRecipes(apiEndpoint, apiKey)
    CALL displayRecipes(recipes)

END FetchRecipesFromAPI

Key Points

• API Request: The fetchRecipes function makes an HTTP GET request to the API endpoint using the provided API key.
• Response Handling: Checks if the response status code is 200 (success) and processes the recipe data.
• Data Processing: The processRecipes function extracts relevant details from the API response into a structured format.
• Display Recipes: The displayRecipes function iterates through the list of processed recipes and displays them in a readable format.

Conclusion

This pseudocode provides a clear and simple framework for fetching and displaying recipes from an API. It ensures that the process is easy to understand and serves as a valuable tool for initial software design.
