Vue.js: What Is it?

Professional developers often face the difficulties associated with user interface creation. Even working in such a comfortable environment as Ruby on Rails, when making changes to the code (and this happens very often), we have to literally “balance” individual software blocks, especially those that relate to the user interface.

With a constant stream of new edits and new code, establishing links between program blocks can turn the process of the development into a real hell.

The question arises: would it not be right to employ tools that can greatly alleviate such a complex process? Frameworks are exactly such instruments. The framework is an embodiment of some idea of development using well-known design patterns, a set of tools and templates that allow simplifying the process of the program creation.

Vue.js is a Javascript framework designed to create user interfaces based on data models, which operates through the reactive data linking. Vue JS was primarily developed as a progressive basis for user interfaces, a presentation-level tool.

However, it is constantly expanding and growing, new features and capabilities appear with an enviable regularity. The ease of linking Vue JS components to other libraries and components has made it a simple and highly functional tool.

Today, with Vue.js you can not only build interfaces but also create very complex single-page applications. In this article, we will describe this tool and tell you about what is so good and convenient about Vue.

What Can Vue.js Do?

The main thing that distinguishes Vue and makes it popular is its simplicity and flexibility. It is easy to learn, intuitive in work, and most importantly – it provides notably high performance, especially in comparison with other popular frameworks.

Main features of the framework:

  • declarative rendering: this mechanism allows reflecting data in the DOM by using simple template syntax
  • simple binding of DOM structures through the use of HTML tags, easily recognized by browsers
  • user data (input) are processed independently of DOM, which provides great efficiency
  • the component system allows developing large applications on the basis of individual Vue JS components, which are then easily linked together
  • several methods for events handling (‘v-on’, inline handlers, set of event modifiers) applicable depending on the required functionality of the Vue website
  • integration of HTML-templates
  • inbuilt mechanics for the animation of the interface elements

Thus, when working with Vue.js, the developer can quickly create and edit on-the-fly the user interface, write individual code blocks, easily linking them with the help of event handling tools.

HTML tags allow us to bind DOM data using a simple syntax. To demonstrate Vue JS examples, here is an instance of code that uses the ‘v-bind’ attribute used for HTML markup:

View the code on Gist.

Simple, is it not?

Vue.js in VS other popular tools

To consider the advantages of Vue, it is worthwhile to compare the framework to other similar products.

Vue vs React

These two frameworks have very many common properties: the implementation of a virtual DOM, the provision of efficient reactive and composite viewing elements, and much more.

We might also note the more extensive functionality of React, which is fair. However, the differences and advantages of Vue JS over React lie in the details. When the page state changes, React updates each component every time, while the Vue structure allows pinpointing which components need to be updated when making changes.

As a consequence – Vue has a higher performance and refreshing speed. Regarding the broader functions of React, the following can be said: a narrower Vue focus allows you to solve all the tasks for which it is designed, efficiently, and expediently.

Angular VS Vue

Like Vue, Angular actively employs components in its structure; however, without the TypeScript, it is very difficult in study and coding. The speed and performance of Angular and Vue are quite comparable, however, as in the case with React, Vue, due to its simplicity and convenience, is slightly ahead of Angular by these parameters. And again, the flexibility and wide possibilities for component interaction distinguish Vue for the better.

Actually, Evan You, the creator of Vue.js, originally worked with Angular, but they were unsatisfied with interface design capabilities. In time this discontent served an incentive to create Vue.

Final Thoughts

Of course, it is difficult to call Vue a full-fledged application development tool, but it is hardly possible to find any simpler and more convenient framework for the user interface design today.

Vue is elementary in syntax (which minimizes the number of possible bugs) and easy to master. Thanks to the simple linking of components and the capabilities for the integration of third-party elements, Vue gives developers the ability to quickly create efficient interfaces.

Our company implements Vue in conjunction with Ruby on Rails, which allows creating high-quality scalable applications for highly loaded tasks with excellent intuitive interfaces while spending minimum time and effort on the development.

However, we should keep in mind that no framework, even the most capacitive ones, is a panacea. If you run into problems with performance or codebase during development, then perhaps it is not the framework’s fault.

It is worth to review the architecture of your application, clean out CSS, check the script loading order, and remove the unnecessary tools. This can get rid of the Vue website of a huge number of problems and speed up its operation.
