Embarking on the journey of learning a new technology can often feel like trying to find your way through a dense forest with nothing but a compass. Fear not, for VueJS is the friendly guide you didn’t know you needed, offering the right balance of simplicity and power. This beginner’s guide to getting started with VueJS aims to equip you with the essential knowledge to navigate the world of VueJS with confidence. By the end, you’ll understand why VueJS might just be the secret sauce to making your web development projects more enjoyable and less like wrestling with a spaghetti code monster.

What is VueJS?

VueJS is a progressive JavaScript framework used for building user interfaces (UIs) and single-page applications (SPAs). It’s like that one friend who’s incredibly adaptable, getting along with almost everyone and seamlessly integrating into any group; VueJS is designed from the ground up to be incrementally adoptable. The core library focuses on the view layer only, making it easy to pick up and integrate with other libraries or existing projects, while also being capable enough to power sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

Why Choose VueJS?

  • Simplicity: VueJS’s learning curve is more like a gentle slope. You can build something impressive with minimal effort, making it perfect for those just dipping their toes into the world of web development.
  • Flexibility: Whether it’s a small widget or a full-fledged SPA, VueJS scales with your needs, ensuring that you’re only using what’s necessary for your project.
  • Performance: VueJS ensures minimal optimization efforts, delivering snappy experiences even in complex applications, faster than you can say Vue-tiful.

Setting Up Your First VueJS Project

Setting up your first VueJS project is as simple as making a sandwich. Well, almost. Here’s how you can get started:

Method 1: Using Vue CLI

The Vue Command Line Interface (CLI) is a powerful tool that scaffolds projects and handles dependencies for you, akin to having your own personal project assistant.

  1. First, ensure Node.js and npm are installed on your computer.
  2. Install Vue CLI globally by running npm install -g @vue/cli in your terminal.
  3. Create a new project by executing vue create my-first-vue-project.
  4. Navigate into your project directory and start the development server with npm run serve.
  5. Congratulations, your VueJS application is now running locally!

Method 2: Without Tooling (CDN)

If you’re looking to get your feet wet without diving into the deep end, you can include Vue directly in your HTML file via a CDN.

  1. Create an HTML file and include the following script tag in the : <script src=></script>
  2. In the body, define a div with an id of app.
  3. Below the Vue script tag, add a new script to create a Vue instance targeting the app div.
  4. Voila! You have a basic VueJS app running directly from your HTML file.

This method is great for small experiments or learning purposes, but for larger projects, you’ll want to use the Vue CLI method for better tooling support.

Understanding VueJS Core Concepts

Now that you have your VueJS environment set up, let’s dive into some core concepts that will form the foundation of your VueJS knowledge.

The Vue Instance

At the heart of every Vue application is the Vue instance. Think of it as the control center for your app, where you define what data to track, computations, and actions to perform in response to user inputs.


Vue’s reactivity system ensures that your UI updates automatically whenever your app’s state changes. It’s like having a personal assistant who refreshes your coffee cup without you needing to ask.


Components are reusable Vue instances that help break up the application into smaller, manageable pieces. Using components is like building with Lego; you can create stunning structures (or web apps) by snapping together small, reusable blocks.


Vue directives are special tokens in the markup that instruct the library to do something to a DOM element. For example, v-bind helps bind an attribute to an expression, and v-for allows you to render a list dynamically.

Building Your First Component

Let’s put theory into practice by creating a simple counter component:

  1. In your project, define a new Vue component named Counter that will keep track of a count variable.
  2. Use the template option to define your component’s HTML structure, which should include a button to increment the count.
  3. Bind the button’s click event to a method that increments the count.
  4. Finally, use your Counter component in the app’s main instance.

    VueJS Best Practices

    As you embark on your VueJS journey, here are some best practices to keep in mind:

    • Keep your components small and focused.
    • Utilize computed properties and watchers wisely to manage complex logic efficiently.
    • Embrace the VueJS style guide to ensure your code is clean, readable, and maintainable.


    You’ve now dipped your toes into the vast ocean of VueJS, equipped with the basics to start building impressive applications. Remember, learning VueJS is a journey, much like trying to find the most comfortable pair of shoes. It might take some time to get there, but the walk will be worth it. Remember, even Rome wasn’t built in a day, and your mastery of VueJS will grow as you continue to build and experiment. Keep practicing, stay curious, and most importantly, have fun with it. And hey, if you ever get stuck, remember that the only dumb question is the one not asked—or in programming terms, a syntax error.
