Recipe App With Javascript

Hey everyone. Welcome to today’s tutorial. In today’s tutorial, we will learn how to create a Recipe App. To build this tutorial we need HTML, CSS and javascript.

In this project, we make use of the MealDB API. This API is easy to use. I would suggest this project for people who have basic knowledge of fetch().

The project consists of search input and a search button. The user enters the dish name of his choice into this input and hits the search button. When the user clicks on the search button, it displays an image of the respective meal, its name, and the country of origin.

Along with this, we also show a list of ingredients along with the measure. Next to the ingredients, we have a ‘View Recipe’ button. When the user clicks on this button, a pop up opens up with the instructions to cook the meal.

Project Folder Structure:

Before we get to the coding, let us take a look at the project folder structure. We create a project folder called – “Recipe App”. Inside this folder, we have three files. The first one is index.html which is the HTML document. Next, we have style.css which is our stylesheet. And finally, we have script.js which is the script file.

HTML:

Let us begin with the HTML code. First copy the code provided to you below and paste it into your HTML file. The HTML code creates elements that are necessary to create the structure of the app.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Recipe App</title>
    <!-- Google Fonts -->
    <link
      href="https://fonts.googleapis.com/css2?family=Poppins:wght@400;600&display=swap"
      rel="stylesheet"
    />
    <!-- Stylesheet -->
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <div class="container">
      <div class="search-container">
        <input
          type="text"
          placeholder="Type A Dish Name Here.."
          id="user-inp"
        />
        <button id="search-btn">Search</button>
      </div>
      <div id="result"></div>
    </div>
    <!-- Script -->
    <script src="script.js"></script>
  </body>
</html>

CSS:

Next, we need to style these elements. For this we use CSS. Now copy the code below and paste it into your stylesheet.

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
  font-family: "Poppins", sans-serif;
}
body {
  background-color: #f4c531;
}
.container {
  background-color: #ffffff;
  font-size: 16px;
  padding: 3em 2.8em;
  width: 90vw;
  max-width: 32em;
  position: absolute;
  transform: translate(-50%, -50%);
  left: 50%;
  top: 50%;
  border-radius: 0.6em;
}
.search-container {
  width: 100%;
  display: grid;
  grid-template-columns: 9fr 3fr;
  gap: 1.2em;
}
.search-container input {
  font-size: 1em;
  padding: 0.6em;
  border: none;
  outline: none;
  border-bottom: 2px solid #202030;
}
.search-container button {
  font-size: 1em;
  background-color: #f4c531;
  border: none;
  font-weight: 600;
  border-radius: 0.3em;
}
img {
  display: block;
  width: 50%;
  margin: 1.8em auto 0 auto;
}
.details {
  background-color: #f4c531;
  position: relative;
  margin: -4.3em 0 0 0;
  text-align: center;
  padding: 0.6em 0;
}
.details h2 {
  font-size: 1.2em;
  font-weight: 600;
}
.details h4 {
  font-size: 1em;
  font-weight: 400;
}
#show-recipe {
  font-size: 1em;
  position: relative;
  left: 75%;
  padding: 0.9em 0.6em;
  background-color: #f4c531;
  border: none;
  top: 1.5em;
  border-radius: 0.3em;
  font-weight: 600;
}
#recipe {
  position: absolute;
  background-color: #ffffff;
  min-height: 100%;
  width: 100%;
  top: 0;
  left: 0;
  z-index: 2;
  border-radius: 0.6em;
  display: none;
}
#recipe pre {
  white-space: pre-wrap;
  word-wrap: break-word;
  padding: 2.5em 1.2em 1.2em 1.2em;
  font-size: 0.92em;
  color: #303040;
}
#hide-recipe {
  font-size: 1em;
  position: relative;
  width: 1.8em;
  height: 1.8em;
  background-color: #f4c531;
  border: none;
  top: 1.2em;
  left: 90%;
  border-radius: 0.3em;
}
ul {
  font-size: 1em;
  position: relative;
  display: grid;
  grid-template-columns: auto auto;
  gap: 0.8em 1.1em;
  padding: 1.2em 0 0 1.2em;
  color: #303040;
  text-transform: capitalize;
}
h3 {
  text-align: center;
  margin-top: 1.8em;
  color: #202030;
}
@media screen and (max-width: 500px) {
  .container {
    font-size: 14px;
  }
}

Javascript:

Finally, we add functionality to this project using Javascript. Once again copy the code below and paste it into your script file.

//Initial References
let result = document.getElementById("result");
let searchBtn = document.getElementById("search-btn");
let url = "https://www.themealdb.com/api/json/v1/1/search.php?s=";

searchBtn.addEventListener("click", () => {
  let userInp = document.getElementById("user-inp").value;
  if (userInp.length == 0) {
    result.innerHTML = `<h3>Input Field Cannot Be Empty</h3>`;
  } else {
    fetch(url + userInp)
      .then((response) => response.json())
      .then((data) => {
        let myMeal = data.meals[0];
        console.log(myMeal);
        console.log(myMeal.strMealThumb);
        console.log(myMeal.strMeal);
        console.log(myMeal.strArea);
        console.log(myMeal.strInstructions);
        let count = 1;
        let ingredients = [];
        for (let i in myMeal) {
          let ingredient = "";
          let measure = "";
          if (i.startsWith("strIngredient") && myMeal[i]) {
            ingredient = myMeal[i];
            measure = myMeal[`strMeasure` + count];
            count += 1;
            ingredients.push(`${measure} ${ingredient}`);
          }
        }
        console.log(ingredients);

        result.innerHTML = `
    <img src=${myMeal.strMealThumb}>
    <div class="details">
        <h2>${myMeal.strMeal}</h2>
        <h4>${myMeal.strArea}</h4>
    </div>
    <div id="ingredient-con"></div>
    <div id="recipe">
        <button id="hide-recipe">X</button>
        <pre id="instructions">${myMeal.strInstructions}</pre>
    </div>
    <button id="show-recipe">View Recipe</button>
    `;
        let ingredientCon = document.getElementById("ingredient-con");
        let parent = document.createElement("ul");
        let recipe = document.getElementById("recipe");
        let hideRecipe = document.getElementById("hide-recipe");
        let showRecipe = document.getElementById("show-recipe");

        ingredients.forEach((i) => {
          let child = document.createElement("li");
          child.innerText = i;
          parent.appendChild(child);
          ingredientCon.appendChild(parent);
        });

        hideRecipe.addEventListener("click", () => {
          recipe.style.display = "none";
        });
        showRecipe.addEventListener("click", () => {
          recipe.style.display = "block";
        });
      })
      .catch(() => {
        result.innerHTML = `<h3>Invalid Input</h3>`;
      });
  }
});
