React Crash Course | Build A Full Recipe App

Introduction to React.js

React.js is a JavaScript library for building user interfaces. It allows developers to build reusable UI components
that can be combined to create complex web applications. In this crash course, we will learn how to build a full
recipe app using React.js.

Getting Started

To follow along with this tutorial, make sure you have Node.js and NPM installed on your computer. You can download
and install them from the official Node.js website. Once you have them installed, open your terminal and run the
following command to create a new React project:

npx create-react-app recipe-app

This will create a new folder named “recipe-app” with a basic React project structure. Navigate to the project
folder by running:

cd recipe-app

Now, you’re ready to start building our recipe app!

Building the Recipe App

In this tutorial, we will build a recipe app that allows users to search for recipes, view recipe details, and save
their favorite recipes. We will be using React hooks for state management and the Edamam API for accessing recipe
data.

Step 1: Creating Components

To start, let’s create our main components. We will have three components: Search for the search bar and
results, Recipe for displaying individual recipes, and Favorites for managing favorite
recipes.

<div id="root">
    <Search />
    <Recipe />
    <Favorites />
  </div>

Step 2: Implementing Search Functionality

In the Search component, we will implement the search functionality. This will involve capturing user
input, making API calls to retrieve recipe data, and displaying the results. We will also include pagination for
navigating through the results.

Step 3: Displaying Individual Recipes

In the Recipe component, we will display individual recipe details. This will include the recipe name,
ingredients, instructions, and an option to save the recipe as a favorite.

Step 4: Managing Favorite Recipes

In the Favorites component, we will manage the user’s favorite recipes. This will involve storing the
favorite recipes in the browser’s local storage, retrieving them, and displaying the saved recipes.

Conclusion

In this crash course, we learned how to build a full recipe app using React.js. We covered the basics of React, such
as creating components and managing state using hooks. We also integrated an API for retrieving recipe data and
implemented functionality for saving favorite recipes. With this knowledge, you can now create your own React apps
and expand on the recipe app by adding additional features and enhancements.

Happy coding!
