Recipe Finder App: A Simple Project on JavaScript, HTML, and CSS
In this tutorial, we will create a recipe finder app using JavaScript, HTML, and CSS. The app allows users to search for recipes based on ingredients and displays the results on the page. We will use the Edamam API for retrieving recipe data. Let's get started!
Overview of the Project
The recipe finder app we are going to build is a small project that utilizes JavaScript, HTML, and CSS. The app will have a user interface where users can enter ingredients they have, and the app will provide them with a list of recipes containing those ingredients. We will use the Edamam API to fetch the recipe data from the server.
Setting Up the HTML Structure
To begin, let's create the basic HTML structure for our app. We will start with an index.html file and add the necessary elements, including a form for users to enter ingredients and a div for displaying the search results.
<!DOCTYPE html>
<html>
<head>
<title>Recipe Finder</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div class="container">
<h1>Recipe Finder</h1>
<form>
<input type="text" id="search" placeholder="Enter ingredients">
<button type="submit" id="submit" class="btn">Search</button>
</form>
<div id="results"></div>
</div>
<script src="script.js"></script>
</body>
</html>
In this HTML code, we have a container div with a heading, a form with an input field and a submit button, and a results div for displaying the search results. We have also linked an external CSS file and a JavaScript file for styling and functionality.
Adding Styling with CSS
To make our recipe finder app more visually appealing, let's add some styling using CSS. Create a style.css file and write the following CSS code to apply basic styles to our app.
.container {
text-align: center;
}
h1 {
font-size: 24px;
margin-bottom: 20px;
}
form {
margin-bottom: 20px;
}
input[type="text"] {
width: 300px;
padding: 10px;
font-size: 16px;
}
button {
padding: 10px 20px;
font-size: 16px;
background-color: #f00;
color: #fff;
}
#results {
text-align: left;
}
In this CSS code, we have centered the content of the container, set the font size for the heading, styled the input field and submit button, and aligned the search results to the left.
Writing the JavaScript Code
Now, let's write the JavaScript code to implement the functionality of our recipe finder app. Create a script.js file and add the following code.
// Selecting elements from the HTML document
const searchForm = document.querySelector('form');
const searchInput = document.querySelector('#search');
const resultsList = document.querySelector('#results');
// Adding event listener for form submission
searchForm.addEventListener('submit', function(event) {
event.preventDefault();
searchReceipts();
});
// Implementing the searchReceipts function
async function searchReceipts() {
const searchValue = searchInput.value;
const response = await fetch('https://api.edamam.com/api/recipes?app_id=YOUR_APP_ID&app_key=YOUR_APP_KEY&q=' + searchValue);
const data = await response.json();
displayReceipts(data);
}
// Generating HTML template for each receipt
function displayReceipts(receipts) {
let html = '';
receipts.forEach(function(receipt) {
html += `
<div class="receipt">
<img src="${receipt.image}" alt="${receipt.label}">
<h3>${receipt.label}</h3>
<ul>
${receipt.ingredients.map(ingredient => `<li>${ingredient.text}</li>`).join('')}
</ul>
<a href="${receipt.url}" target="_blank">View Recipe</a>
</div>
`;
});
resultsList.innerHTML = html;
}
In this JavaScript code, we first select the necessary elements from the HTML document using the querySelector method. We then add an event listener to the search form, which listens for the submit event and calls the searchReceipts function.
The searchReceipts function is an asynchronous function that takes the user's search input, fetches the recipe data from the Edamam API, and converts it to JSON format. The data is then passed to the displayReceipts function.
The displayReceipts function generates an HTML template for each receipt using template literals. It loops through the array of receipts, creates the necessary HTML structure, and appends it to the resultsList div.
Testing the App
Save all the files and open the index.html file in a web browser. Type in some ingredients in the search input field and click the search button. The app will fetch the recipe data from the Edamam API and display the search results on the page.
Congratulations! You have successfully created a recipe finder app using JavaScript, HTML, and CSS.
Conclusion
In this tutorial, we have learned how to create a recipe finder app using JavaScript, HTML, and CSS. The app allows users to search for recipes based on ingredients and displays the results on the page. We have utilized the Edamam API to fetch the recipe data from the server. This project serves as a great practice exercise for building small JavaScript projects and utilizing APIs.
Pros of the Recipe Finder App
- Easy and intuitive user interface
- Quick and efficient search functionality
- Access to a wide variety of recipe options
- Provides inspiration for cooking with available ingredients
- Customizable based on user preferences and dietary restrictions
Cons of the Recipe Finder App
- Limited to the recipe database of the Edamam API
- Reliance on internet connectivity to fetch recipe data
- May not always provide the exact recipe a user is looking for
- Potential for inaccuracies in the ingredient matching algorithm
- Lack of personalized recommendations and advanced filtering options
Frequently Asked Questions (FAQs)
Q: Can I add additional features to the recipe finder app?
A: Yes, you can enhance the app by adding features such as advanced filtering options, sorting by cooking time or difficulty, saving favorite recipes, and creating personalized recipe collections.
Q: Is the Edamam API free to use?
A: The Edamam API offers both free and paid plans. The free plan has limitations on the number of API requests and access to certain features. You can check their developer portal for more information on pricing and usage limits.
Q: Can I use a different recipe API instead of Edamam?
A: Yes, there are other recipe APIs available that you can explore, such as Spoonacular, Recipe Puppy, and Food2Fork. However, keep in mind that the implementation may differ based on the API documentation and requirements.
Q: How can I deploy the recipe finder app to a live server?
A: To deploy the app to a live server, you will need to have a hosting service or platform where you can upload your HTML, CSS, and JavaScript files. There are many options available, such as GitHub Pages, Netlify, or deploying to your own web server.
Q: Can I modify the styling of the app?
A: Absolutely! The CSS code provided in this tutorial is just basic styling. You can customize the styles according to your preference and design aesthetics.
Q: How can I make the app more responsive and mobile-friendly?
