How Does Vue.js Work?

Exploring Vue.js: A Progressive Javascript Framework

In your quest for knowledge about Javascript frameworks and Vue.js, you’ve landed on the right page. Vue.js is a cutting-edge Javascript framework designed to facilitate the swift creation of single-page applications. In this comprehensive guide, we’ll delve into what Vue.js represents, its operational principles, and help you determine if it’s the perfect Javascript framework for your needs.

Understanding the “Progressive” in Progressive Frameworks

The term “progressive” within the context of Vue.js holds a significant meaning. It signifies that Vue.js empowers you to commence with minimal functionality and progressively augment your application as per your requirements. Let’s break down what this entails.

1. Vue.js is Lightweight

Vue.js adopts a minimalistic approach, exclusively including the components and libraries essential for your application to run. Weighing in at a mere 18Kb, Vue.js is exceptionally compact. Thanks to its design, once the primary components are downloaded to the user’s device, the core page can begin displaying. This distinguishes Vue.js from frameworks like React, where the entire application must be downloaded before execution.

2. Vue.js is Versatile

One of Vue.js’s remarkable strengths lies in its versatility. It can seamlessly integrate with other frameworks and tools. Regardless of whether your project is already in progress, Vue.js can be introduced incrementally as per the project’s requirements.

Demystifying Javascript Frameworks

Before we dive deeper into Vue.js, let’s elucidate the concept of a Javascript framework, which serves as an architectural blueprint and a programming language combined to lay the foundation for rapid application prototyping and deployment. For a better understanding, let’s draw an analogy with the Linux world.

3. Javascript Frameworks: The Blueprints of Web Development

Much like Arch in the Linux universe, a Javascript framework is akin to the core foundation upon which you build your web application. While it is possible to construct a web app from scratch, akin to building Linux from the ground up, it can be labor-intensive. Conversely, you can employ a framework like Vue.js as the base for your web app, just as Arch serves as the foundation for various Linux distributions like SteamOS or Manjaro. Vue.js, in this analogy, corresponds to Arch, and your web application corresponds to SteamOS.

4. Single-Page Applications Unveiled

Before we delve into the workings of Vue.js, let’s explore what a single-page application (SPA) entails. SPAs are web applications that utilize a framework to replace components within the webpage’s object model without reloading the entire page.

In a nutshell, when you navigate from the home page to the “Contact Me” section in a single-page app, only the central portion of the webpage is updated, rather than loading an entirely new webpage.

How Vue.js Operates

Having laid the groundwork, let’s transition to understanding how Vue.js functions from a developer’s perspective. The process of creating a Vue.js application mirrors that of React, with some nuances.

5. Building a Vue.js App

To initiate a Vue app, you must first install the Vue.js packages via NPM (Node Package Manager). Subsequently, you run a command in the command line to create and initialize a bare Vue project. Like other Javascript frameworks, Vue includes routers, stores, and state management, albeit with unique implementations.

Vue Files: A Tripartite Structure

What distinguishes Vue from other frameworks is the structure of its files, with each Vue file encompassing three main components:

1. HTML Template: This section holds all the HTML for the component.
2. Javascript: The Javascript portion primarily consists of an object that serves as the core of the app.
3. CSS Styling: The third part is dedicated to the CSS styling for the page.

Vue leverages standard HTML to manage visual elements, while also incorporating unique HTML ‘tags’ for tasks like state management and conditional rendering.

Component-Based Development

Each component of the app follows this structure, and there are numerous methods to organize and call components, depending on your preference. These components are used to progressively build the app’s functionality. The Vue store can be utilized across the entirety of the app, and while data can be passed via props between child and parent components, Vue’s file-based approach simplifies the learning curve, making it an efficient choice for web development.

In my personal experience, picking up Vue.js was far quicker and more straightforward compared to learning React and other Javascript frameworks.

In conclusion, Vue.js offers a progressive, lightweight, and versatile approach to building single-page applications. It’s an ideal choice for developers looking to streamline web development, and its ease of use makes it a standout option for both newcomers and seasoned professionals in the field of web development. If you’re ready to embark on your Vue.js journey, you’ll find it to be a valuable addition to your skill set.
