How to Install and Set Up Vue.js for Your Next Project

August 22, 2024
Share this article

Vue.js is a progressive JavaScript framework that is specifically designed for building user interfaces and single-page applications. As a versatile and adaptable framework, it fits the needs of developers who want to make complex user interfaces with simplicity.

One of the main reasons Vue.js has consistently been a popular choice among developers is its ease of integration with existing projects. It's also recognized for its reactivity, which makes creating dynamic interfaces much more straightforward.

Another notable feature is its component-based architecture, which promotes code reusability and maintainability. This comprehensive guide is specifically designed to help developers, both novice and experienced, understand the ins and outs of Vue.js.

It will provide step-by-step instructions on how to install and set up Vue.js using two popular methods, namely the Content Delivery Network (CDN) and the Command Line Interface (CLI). Moreover, it will guide you through the process of creating your first Vue.js project, helping you understand the structure and syntax of Vue.js, and how to apply it to build robust and efficient web applications. 

Prerequisites

Before we dive into the main content, it is crucial to ensure that you have properly set up your environment. Here are the prerequisites you need:

  • A stable and reliable internet connection. This is important as we will be downloading necessary files and resources from the internet. Interruptions in your network connection could lead to incomplete downloads or errors during the installation process.
  • The second crucial requirement is having Node.js and npm (Node Package Manager) installed on your machine. We will use these for the Command Line Interface (CLI) method. Node.js is a runtime environment that allows you to run JavaScript on your server, while npm is the default package manager for Node.js. This duo is crucial for most modern web development tasks.

If you haven't installed Node.js and npm yet, don't worry. Here is a simple guide that you can follow: https://www.cuantum.tech/post/how-to-install-nodejs-on-windows-mac-and-linux-a-stepbystep-guide

So, before proceeding, please ensure you have met all these prerequisites. This will make the following steps smoother and more straightforward. 

Installing Vue.js through a Content Delivery Network (CDN)

One of the most efficient and fastest methods to begin your journey with Vue.js is by utilizing a Content Delivery Network (CDN). A CDN is a globally distributed network of servers that delivers content to users based on their geographic location. This ensures that the content, in this case, Vue.js, is delivered swiftly and efficiently to the end user.

This method of installation is particularly beneficial for those who are just starting to learn Vue.js or those who are working on quick prototyping projects. By using a CDN, you can bypass the need for complex setup processes or extensive downloads. Instead, you are able to begin coding almost immediately, which makes it an ideal solution for beginners or those working under tight deadlines.

In summary, if you're looking for a quick, easy, and efficient way to start learning and working with Vue.js, consider the use of a CDN for your installation needs.

Step 1: Create an HTML File

  1. Open your preferred text editor and create a new file named index.html.
  2. Add the following boilerplate code:
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Vue.js CDN Example</title>
</head>
<body>
    <div id="app">{{ message }}</div>
    <script src="<https://cdn.jsdelivr.net/npm/vue@2.6.12/dist/vue.js>"></script>
    <script>
        new Vue({
            el: '#app',
            data: {
                message: 'Hello Vue.js!'
            }
        });
    </script>
</body>
</html>

Step 2: Open the HTML File in a Browser

  1. Save the index.html file.
  2. Open the file in your web browser to see "Hello Vue.js!" displayed on the page.

This simple example demonstrates how easy it is to get started with Vue.js using a CDN.

Installing Vue.js via CLI

For larger projects, using the Vue CLI (Command Line Interface) is recommended. It provides a robust set of tools and optimizations for developing and maintaining Vue.js applications.

Step 1: Install Vue CLI

  1. Open your terminal and install Vue CLI globally using npm:
npm install -g @vue/cli

Step 2: Create a New Vue Project

1. Create a new project by running:

vue create my-vue-project

2. Follow the prompts to set up your project. You can choose the default preset or manually select features.

Step 3: Navigate to the Project Directory

  1. Change to the project directory:
cd my-vue-project

Step 4: Run the Development Server

1. Start the development server by running:

npm run serve


2. Open your browser and navigate to http://localhost:8080 to see your new Vue.js application in action.

Building Your First Project with Vue.js

Now that you have successfully set up Vue.js on your system, it's time to dive into the world of Vue.js and start creating your very first application. This will be a simple, introductory project aimed at showcasing the extensive capabilities and innovative features that Vue.js brings to the table.

Whether you're a seasoned developer or a beginner just starting out, this project will provide a practical, hands-on experience to help you understand the power of Vue.js and how it can transform the way you approach web development. Let's get started!

Step 1: Modify the Default Template

  1. Open the src directory in your project and locate the App.vue file.
  2. Replace the default template with the following code:
<template>
  <div id="app">
    <h1>{{ title }}</h1>
    <input v-model="newTodo" @keyup.enter="addTodo" placeholder="Add a new task">
    <ul>
      <li v-for="todo in todos" :key="todo.id">
        <input type="checkbox" v-model="todo.done">
        <span :class="{ done: todo.done }">{{ todo.text }}</span>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      title: 'Vue.js Todo List',
      newTodo: '',
      todos: [
        { id: 1, text: 'Learn Vue.js', done: false },
        { id: 2, text: 'Build a project', done: false }
      ]
    };
  },
  methods: {
    addTodo() {
      if (this.newTodo.trim() === '') return;
      this.todos.push({
        id: this.todos.length + 1,
        text: this.newTodo,
        done: false
      });
      this.newTodo = '';
    }
  }
};
</script>

<style>
.done {
  text-decoration: line-through;
}
</style>

Step 2: Save and View Your Application

  1. Save the changes to the App.vue file.
  2. Your development server should automatically reload. Open your browser and navigate to http://localhost:8080 to see your new Vue.js Todo List application.
