VueJs: Everything You Need to Know About…
Until the early 2000s, browsers didn’t have the capabilities they have now. They were a lot less powerful, and building complex applications inside them were not feasible performance-wise. The tooling was not even something that people thought about.
Note that jQuery, Ember and the other projects I mentioned are still being heavily used, actively maintained, and millions of websites rely on them.
Using a framework is like using the C or C++ programming language instead of using the Assembly language to write system programs. It’s like using a computer to write a document instead of using a typewriter. It’s like having a self-driving car instead of driving the car yourself.
Well, not that way, but you get the idea. Instead of using low-level APIs offered by the browser to manipulate elements, and building hugely complex systems to write an application, you use tools built by very smart people that make our life easier.
Here’s are the advantages of using Vue.js technology in web development.
1- Small In Size
2- Very Easy to Understand and Develop Applications
One of the reasons for the popularity of this framework is that it is quite easy to understand. The user will simply add Vue.js to his web project because of its simple structure. Both the little moreover as massive scales templates may be developed through this framework that saves a great deal of your time. In case of any downside, the user will simply trace the blocks with errors. All this is because of its simple structure.
And last but not least Vue.js also facilitates two-way data-binding because of its MVVM architecture which makes it quite easy to handle HTML blocks. In this respect, it seems very close to AngularJs and Angular which also speeds up HTML blocks.
In the end, we will say that Vue.js has clear advantages over all the earlier frameworks like AngularJs and React.js. In short, it combines the peculiar features of all the older frameworks. We at ProximityCR have lots of experience working with bit different JS Frameworks and that we can tell you that we actually like Vue.JS and it’s here to stay.
The popularity of Vue
How popular is Vue.js?
7,600 stars on GitHub in 2016
36,700 stars on GitHub in 2017
And it’s quite 100,000+ stars on GitHub, as of June 2018.
Its npm download count is growing every day, and now it’s at ~350,000 downloads per week.
I would say Vue is extremely popular, given those numbers.
In relative terms, it’s around the same numbers of GitHub stars as React, that was born years before.
Numbers are not everything, of course. The impression I have of Vue is that developers like it.
A key purpose in a time of the rise of Vue has been the adoption within the Laravel ecosystem, a hugely popular PHP web application framework. But since then it has become widespread among many other development communities.
Why developers love VueJs
First, Vue is called a progressive framework. This means that it adapts to the needs of the developer. Other frameworks require a complete buy-in from a developer or team and often want you to rewrite an existing application because they require some specific set of conventions. Vue easily lands within your app with a simple script tag to start with, and it can grow along with your needs, spreading from 3 lines to managing your entire view layer.
Vue.js is maybe the foremost approachable front-end framework around. Some individuals decision Vue the new jQuery, because it easily gets in the application via a script tag, and gradually gains space from there. Think of it as a compliment, since jQuery dominated the Web in the past few years, and it still does its job on a huge number of sites.
Vue was designed by choosing the simplest concepts of frameworks like Angular, React and Knockout, and by cherry-picking the simplest decisions those frameworks created. And by excluding some less brilliant ones, it kind of started as a “best-of” set and grew from there.
Where does Vue.js position itself within the frameworks landscape?
The two elephants within the space, when talking concerning web development, area unit React and Angular. How will Vue position itself relative to those 2 huge and popular frameworks?
Vue was created by Evan You when he was working at Google on AngularJS (Angular 1.0) apps. It was born out of a need to create more performant applications. Vue picked some of the Angular templating syntaxes but removed the opinionated, complex stack that Angular required, and made it very performant.
The new Angular (Angular 2.0) also solved many of the AngularJS issues, but in very different ways. It also requires a buy-in to TypeScript which not all developers enjoy using (or want to learn).
What about React? Vue took several good ideas from React, most importantly the Virtual DOM. But Vue implements it with some type of automatic dependency management. This tracks which components are affected by a change of the state so that only those components are re-rendered when that state property changes.
In ReactJs, when a part of the state that affects a component changes, the component will be re-rendered. By default, all its children will be re-rendered as well. To avoid this you would like to use the ought toComponentUpdate methodology of every element and verify if that element should be re-rendered. This gives Vue a bit of an advantage in terms of ease of use, and out of the box performance gains.
One big difference between React is JSX. While you’ll technically use JSX in Vue, it’s not a popular approach and instead, the templating system is used. Any HTML file is a valid Vue template. JSX is very different from HTML and has a learning curve for people on the team that might only need to work with the HTML part of the app, like designers.
Vue templates are similar to mustache and Handlebars (although they differ in terms of flexibility). As such, they’re additionally acquainted with developers that already used frameworks like Angular and ember.
Again, this is part of the positive things about Vue, which saw this good pattern to React and borrowed it for its ecosystem. And whereas you’ll be able to use redux with Vue, Vuex is specifically tailored for Vue and its inner workings.
Vue is flexible, but the fact that the core team maintains two packages that are very important for any web app (like routing and state management) makes it a lot less fragmented than React.
You don’t need to choose or worry if that library you chose is going to be maintained in the future and will keep up with framework updates. Since they are official, they are the canonical go-to libraries for their niche (but you can choose to use what you like, of course).
One thing that puts Vue in a different bucket compared to React and Angular is that Vue is an indie project: it’s not backed by a massive corporation like Facebook or Google. Instead, it’s utterly backed by the community, that fosters development through donations and sponsors. This makes sure the roadmap of Vue isn’t driven by a single company’s agenda.
The installation for VueJS is incredibly simple to start out with. Any developer will simply understand and build interactive web interfaces in a matter of time. VueJS is Design and Developed by Evan You, an ex-employee from Google. The VueJS v 1.0 was released on Feb 2014. It recently has clocked to more than 64,828 stars on GitHub, making it very popular.
Following are the features available with VueJS
The data binding feature helps manipulate or assign values to markup language attributes, amendment the fashion, assign categories with the assistance of binding directive referred to as v-bind on the market with VueJS.
Components are building blocks as well as one of the important features of VueJS that helps create custom elements, which can be reused in HTML.
V-on is the attribute added to the DOM elements to listen to the events in VueJS to improve app performance.
VueJS provides different ways to apply a transition to HTML elements when they are added/updated or removed from the DOM. VueJS incorporates a built-in transition component that must be wrapped around the part for the transition effect. We can simply add third party animation libraries and also add a lot of interactivity to the interface.
This is one of the important features of VueJS. It helps to listen to the changes made to the UI elements and performs the necessary calculations. There is no need for additional coding for this.
VueJS provides HTML-based templates that bind the DOM with the Vue instance data ( binds with app data ). Vue manipulates and compiles the templates into Virtual DOM Render functions. We can make use of the template of the render functions and to do so we have to replace the template with the render function.
VueJS has built-in directives such as v-if, v-else, v-show, v-on, v-bind, and v-model, which are used to perform various actions on the frontend.
Watchers are applied to data that changes. For example, form input elements. Here, we don’t have to add any additional events. Watcher takes care of handling any data changes creating the code easy and fast.
Navigation between pages is performed with the use of vue-router.
VueJS script is very lightweight and the performance is also very fast.
VueJS can be installed at the command line using the vue-cli command-line interface. It helps to create and compile the project simply using vue-cli.
Comparison with Other Frameworks
Now let us compare VueJS with other frameworks such as React, Angular, Ember, Knockout, and Polymer.
VueJS v/s React
“VueJS and React both use virtual DOM, which makes it faster.”
Template v/s JSX
VueJS uses HTML, js, and CSS separately. It is very easy for a beginner to understand and adopt the VueJS style. The template-based approach in components for VueJS is very easy.
React uses the CLI command to create react app and VueJS use vue-cli /CDN/npm. Both are very easy to use and the project is set up with all the basic requirements. React requires the webpack for the build, whereas VueJS does not. We can start the development with VueJS coding within jsfiddle or codepen using the CDN library.
VueJS is a developing framework. Presently, the job opportunities with VueJS framework are less in comparison to React According to a survey, nowadays many people are adapting to VueJS, which can make it more popular in comparison to React and Angular. There is a good community working on the different features of VueJS. The Vue-router is maintained by this huge community with regular updates.
VueJS has taken the good parts from Angular and React and has built a powerful library. VueJS is much quicker as compared to React/Angular because of its light-weight library.
VueJS v/s Angular
VueJS has a lot of similarities with Angular. Directives such as v – if, v – for are almost similar to ng If, ng For of Angular. They both have a command-line interface for project installation and to build it. VueJS uses Vue – cli and Angular uses angular-cli. Both offer one way and two-way data binding, server-side rendering, etc.
Vuejs is very easy to learn and start with. As discussed earlier, a beginner can take the CDN library of VueJS and get started in codepen and jsfiddle.
To decide the performance, it is up to the users. VueJS file size is much lighter than Angular.
At present, Angular is more popular than VueJS. A lot of organizations nowadays use Angular, making it very popular. Job opportunities are also more for candidates experienced in Angular. However, VueJS is now rapidly taking up the place in the market and can be considered as a good competitor for Angular and React.
Angular provides a lot of built-in features. We have to import the required modules and get started with it, for example, @angular/animations, @angular/form. VueJS does not have all the built-in features as Angular and needs to depend on third-party libraries to work on it.
VueJS can be easily merged or implement with any other project without any issues. Angular will not be that easy to start working with any other existing project as easy as Vue.
We had AngularJS, Angular2 and now Angular4. AngularJS and Angular2 have a vast difference. Project application developed in AngularJS cannot be converted to Angular2 because of the core differences.The recent version of VueJS is 2.0 and it is good with backward compatibility. It provides good documentation and guide-lines, which is very easy to understand.
VueJS v/s Ember
Ember provides Ember command-line tool, i.e. ember-cli for easy installation and compiling for Ember projects.VueJS has also a command-line interface tool vue-cli to start and build projects. They both have features such as components, templates, and router which makes them very rich as the UI framework.
VueJS v/s Knockout
Knockout provides good browser support. It is supported on the lower version of the IE whereas VueJS is not supported on IE8 and below. Knockout development has slowed down over time. There is not a lot of quality for a similar in recent times.
On the other hand, VueJS has started gaining popularity with the VueJs framework team providing regular updates.
VueJS v/s Polymer
Polymer library has been developed by Google. It is used in many Google projects such as Google I/O, Google Earth, Google Play Music, etc. It offers data binding ( one way and two way ) and computed properties similar to VueJS.
Vue as a library
There are several ways in which you can use or implement Vue into your existing web project. Let’s start with the simplest one (which you will probably not end up using a lot).
Most tutorials/articles will assume that you have some understanding of how to set up a development environment in which you will use things like npm, webpack to set up your project – and while this is ideal because of what you get out of the box – we can start with a much simpler beginner-friendly approach. The reliable old script tag.
Go ahead and fire up your favorite code editor, and create a new file called index.html. (If you don’t have one yet, VS Code is a popular free choice.
