Examples: shopping lists
Basics
A quick start example is provided in the corresponding API page. Note that it is Recipe
objects that are passed to the add_recipe()
method.
Adding scaled recipes
You can specify a number of servings for which the recipe should be scaled before being added with add_recipe()
. Example:
shoppingList.add_recipe(myRecipe, 4)
When adding a recipe, the combined list of ingredients of the shopping list is automatically calculated, and the ingredients categorized if a CategoryConfig
has been set.
Removing recipes
You can remove the recipe by passing the index of the recipe to remove to the remove_recipe()
. The list of indexes is accessible via the recipes
property of the ShoppingList
. Example:
shoppingList.remove_recipe(0)
Optional: Category Configuration
You can provide a CategoryConfig to the ShoppingList in order to categorize ingredients in your shopping list. Categories can be aisles in a supermarket, or different supermarkets or anyhow else you would like to categorize your ingredients.
Creating a category configuration
See CategoryConfig
Prodiving a category configuration to the shopping list
Either when initializing the ShoppingList
or afterwards:
const myConfig = new CategoryConfig(`...`)
const shoppingList = new ShoppingList(myConfig)
// or
const shoppingList = new ShoppingList()
shoppingList.set_category_config(myConfig)
Categorizing according to the category configuration
This is done automatically each time you add or remove a recipe.
