Backend Challenge - Recipe API

Introduction

The "Recipe API" challenge is designed to build a RESTful API that allows management of recipes, including CRUD operations for recipes, ingredients, and categories.

Objectives

  • Set up a web server capable of handling API requests.
  • Implement endpoints for CRUD operations on recipes, ingredients, and categories.
  • Handle recipe details (e.g., title, description, ingredients, instructions).
  • Understand HTTP methods (GET, POST, PUT, DELETE) and status codes.

Instructions

  1. Objective: Develop a RESTful API that provides functionality for managing recipes.

  2. Environment Setup: Choose your preferred programming language (e.g., JavaScript, Python, Java, C#) and set up the necessary environment.

  3. Implementation Details:

    • Define endpoints for recipes (/recipes), ingredients (/ingredients), and categories (/categories):
      • GET /recipes: Retrieve all recipes.
      • POST /recipes: Create a new recipe.
      • GET /recipes/{recipeId}: Retrieve details about a specific recipe.
      • PUT /recipes/{recipeId}: Update an existing recipe.
      • DELETE /recipes/{recipeId}: Delete a recipe.
      • GET /ingredients: Retrieve all ingredients.
      • POST /ingredients: Create a new ingredient.
      • GET /ingredients/{ingredientId}: Retrieve details about a specific ingredient.
      • PUT /ingredients/{ingredientId}: Update an existing ingredient.
      • DELETE /ingredients/{ingredientId}: Delete an ingredient.
      • GET /categories: Retrieve all categories.
      • POST /categories: Create a new category.
      • GET /categories/{categoryId}: Retrieve details about a specific category.
      • PUT /categories/{categoryId}: Update an existing category.
      • DELETE /categories/{categoryId}: Delete a category.
    • Implement logic to interact with recipe, ingredient, and category data (e.g., store in database).
    • Include fields such as recipe title, description, ingredients list, instructions, and category associations.

  4. Testing: Test your API using a HTTP client (e.g., Postman, curl).

    • Send requests to each endpoint (/recipes, /ingredients, /categories) with appropriate data payloads (e.g., JSON for creating/updating recipes, ingredients, categories).
    • Verify that the responses contain the expected data and that status codes are appropriate (e.g., 200 OK, 404 Not Found).

Possible Improvements

  • Search Functionality: Implement search functionality to allow users to search for recipes by title, ingredients, or categories.
  • Pagination: Implement pagination for listing recipes, ingredients, and categories.
  • Error Handling: Enhance error messages and responses for invalid requests or when data is not found.
  • Authentication: Secure API endpoints, especially those involving sensitive operations like creating, updating, or deleting recipes.
  • Unit Tests: Write unit tests to validate API functionality and data interactions.

Conclusion

By completing this challenge, you will gain practical experience in developing a Recipe API and learn essential practices for backend development. Explore additional improvements and challenges to further enhance your skills.

Happy coding!
