In this lab, you will be building a recipe CRUD app using Node's ability to persist data to a file. You will be using the built-in fs module and JSON methods to read and write to a data file in JSON format.

Students should get hands-on experience with:

• Using Node's fs module to read and write to a file
• Using JSON.parse and JSON.stringify to convert between JSON and JavaScript objects

Students should start internalizing the concepts of:

• CRUD operations
• persistence

You will have some recipes to start with in recipea-data.json. You will have to create a JavaScript file to run your code.

You will know you're successful when you can run your JS file in the following ways, where [filename] is the name you picked for your JavaScript file (without the brackets, which simply indicate that it is a placeholder).

• node [filename] read will get all recipes in the recipes array.
• node [filename] read [i] will get a single recipe at that index in the recipes array.
• node [filename] create [recipe name] [cooking method] [ingredient 1] [ingredient 2] [...]

For example, if you named your file index.js, then node index.js read will get all recipes in the recipes array and log them to the console.

If you named your file recipea.js, then node recipea.js read 0 will get the first recipe in the recipes array and log it to the console.

if you named your file good-look-cook-book.js, then node good-look-cook-book.js create "Spaghetti with White Sauce" "stove-stop boil" "spaghetti" "butter" "flour" "milk" "salt" "pepper" "garlic" "parmesan cheese" will create a new recipe with the name "Spaghetti with White Sauce", the cooking method "stove-stop boil", and the ingredients "spaghetti", "butter", "flour", "milk", "salt", "pepper", "garlic", and "parmesan cheese", and add it to the recipes array in the data file.

The data in recipea-data.json is an array of recipes. Each recipe is an object with the following properties:

• name - the name of the recipe
• cookingMethod - the cooking method of the recipe
• ingredients - an array of ingredients

Check out the data in recipea-data.json to see what that looks like.

• Create a JavaScript file to run your code.
• Create a read command that will read all recipes from the data file and log them to the console.
• Create a read command that will read a single recipe from the data file and log it to the console.
• Create a create command that will create a new recipe and add it to the data file.

These goals are all entirely optional, and none of them are required to complete the lab. They are simply here to give you ideas for how to extend your app.

You should not attempt any of these until you have completed the requirements above.

• Create an update command that will update a recipe in the data file.
• Create a delete command that will delete a recipe from the data file.
• Create a delete command that will delete all recipes from the data file.
• Create a name-filter command that will filter recipes by name and log them to the console.
• Modify the above name-filter command to allow for partial matches.
• Create a cooking-method-filter command that will filter recipes by cooking method and log them to the console.
• Create an ingredient-filter command that will filter recipes by ingredient and log them to the console.
