How to create a Modal Component with Vue.js

Let’s create a new component called Modal.vue inside the components folder.

Now, add the following code.

<template>
   <div>
      <div v-if="isOpen">
          <h1>Modal heading</h1>
          <p>This my first modal using vue.js</p>
      </div>
      <button @click="isOpen=!isOpen">Open modal</button>
   </div>
</template>


<script>
   export default{
       data:function(){
          return {
      isOpen: false
    };
       }
   }
</script>

Here we created our modal template with two div tags and one button element. The button is used to open our modal.

In our second div tag, we added a v-if=isOpen directive so that our modal will only open if the isOpen property is true.

Let’s test our modal component by importing it inside the App.vue file, don’t worry we will add styles and transitions too.

If we toggle on a Open modal button our modal will open.

Vue offers us a custom transition element which helps us to add and remove the transitions to our HTML elements.

Let’s add the styles and transitions to our Modal component.

<template>
  <div>
    <transition name="modal">      
      <div v-if="isOpen">
        <div class="overlay" @click.self="isOpen = false;">
          <div class="modal">
            <h1>Modal heading</h1>
            <p>This my first modal using vue.js</p>
          </div>
        </div>
      </div>
    </transition>
    <button @click="isOpen = !isOpen;">
      {{ isOpen ? "Close" : "Open" }} modal
    </button>
  </div>
</template>

<script>
export default {
  data: function() {
    return {
      isOpen: false
    };
  }
};
</script>

<style scoped>
.modal {
  width: 500px;
  margin: 0px auto;
  padding: 20px;
  background-color: #fff;
  border-radius: 2px;
  box-shadow: 0 2px 8px 3px;
  transition: all 0.2s ease-in;
  font-family: Helvetica, Arial, sans-serif;
}
.fadeIn-enter {
  opacity: 0;
}

.fadeIn-leave-active {
  opacity: 0;
  transition: all 0.2s step-end;
}

.fadeIn-enter .modal,
.fadeIn-leave-active.modal {
  transform: scale(1.1);
}
button {
  padding: 7px;
  margin-top: 10px;
  background-color: green;
  color: white;
  font-size: 1.1rem;
}

.overlay {
  position: fixed;
  top: 0;
  left: 0;
  display: flex;
  justify-content: center;
  align-items: center;
  width: 100%;
  height: 100%;
  background: #00000094;
  z-index: 999;
  transition: opacity 0.2s ease;
}
</style>

In the above code, we wrapped our modal with transition element.

transition: In transition element, we need to add a name attribute with transition name.
