In this article, you are going to learn about how to fix vue component not rendering.

In my learning journey of VueJs, I have faced many problems. “fix vue component not rendering” is one of them. I have faced this problem when I was an absolute beginner and try to render a very basic component but got myself stuck. To make your learning journey smooth I will share my experience about how I got into this problem and the solution to it so that you can take yourself one step ahead in the journey of learning VueJs.

This is my HTML code, where I add a component and print a simple message for practice purposes and I was expecting my component will run successfully. But it didn’t render anything, I was getting only the data of the message. The main reason was I add my component outside of the mounting element which was “app”.

Solution: The solution for me was, I need to use the component inside the app. See the below code with output also:

HTML

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <link rel="stylesheet" href="style.css">
 
  <title>Vue Basic</title>
</head>
<body>
  <div id="app">
    <div>
      <ol>
        <students-name></students-name>
      </ol>
    </div>
    <p>{{ message }}</p>
  </div>
  <script src="<https://cdn.jsdelivr.net/npm/vue@2.6.14/dist/vue.js>"></script>
  <script src="app.js"></script>
</body>
</html>

Here, I was using CDN file, and in the app id I used my component and below the component I simply print a greeting message.

VueJS

Vue.component('students-name', {
  template: '<li>This is a list of students name</li>'
})

new Vue({
  el: '#app',
  data: {
    message: 'Thank You Fromt The Author'
  }
})

Here, at first, I defined the component and then initialize the vue instance with new Vue and set a simple message into it.

Output: After following this approach I was able to fix my problem “vue component not rendering” and successfully get the desired output.
