Comparative analysis of Angular and Vue.js

Vue.js is an open source JavaScript framework that can help developers build beautiful web interfaces. The excellent features of Vue.js are greatly enhanced when used in conjunction with other network tools. Today, many developers have begun to use Vue.js to replace Angular and React.js.

So how should developers choose between Angular and React.js?

Below we will introduce and compare these two frameworks in depth.

Vue.js was developed by former Google employee Evan You and released in 2014. It has now received more than 57,000 GitHub stars. Many developers highly recommend Vue because it is easy to learn. If you have a strong foundation in HTML, CSS, and JavaScript, learning Vue.js only takes a few hours.

What’s most attractive about Vue to developers is its novelty, lightness, and little to no complexity. Vue is not only very flexible and simple, but also very powerful. It also provides two-way data binding functions, just like the virtual DOM functions of Angular and React.

Vue helps developers build applications any way they want, which Angular cannot.

Vue.js - Diverse JavaScript Framework

As a cross-platform, highly progressive framework, Vue has become the first choice for many developers who need to create single-page applications. In a typical MVC architecture for developing web applications, Vue acts as a View, meaning it allows developers to see the displayed portion of the data. In addition to the basic functions mentioned above, Vue has many other excellent functions.

Let’s take a look at these:

1. Easy to use

If you have been using other frameworks, then you can easily use Vue because Vue’s core library focuses on View layer, you can easily integrate it with third-party libraries and use it with existing projects.

2. Lightweight

Since Vue mainly focuses on ViewModel or two-way data binding, Vue is very light. Vue also has very basic documentation. Vue is used as a View layer, which means developers can use it as a highlight feature on the page. Vue provides a better choice than a comprehensive SPA.

3. The learning curve is very low

Developers who are familiar with HTML will find that the learning curve of Vue is very low. At the same time, developers with less experience and beginners can also quickly learn Vue. Learn and understand Vue.

4. Two-way binding

Vue provides the v-model directive (used to update data on user input events), making it easy to implement two-way binding on form inputs and structural elements. easy. It can choose the correct way to update input type related elements.

5. Virtual DOM

Since Vue is a lightweight virtual DOM implementation based on Snabbdom, the performance of Vue has been slightly improved. This is one of the major new features of Virtual DOM, which can be updated directly by developers. You only need to execute such an update function once when you need to make changes in the actual DOM.

6. HTML template-based syntax

Vue allows developers to directly bind the rendered DOM to the underlying Vue instance data. This is a useful feature because it allows developers to extend basic HTML elements to save reusable code.

Angular: Dynamic Framework

Angular is a full-featured framework that supports the Model-View-Controller programming structure and is ideal for building dynamic single-page web applications.

Google developed and supports Angular in 2009. Angular includes a JS code library based on standard JavaScript and HTML. Angular was originally designed as a tool that enables designers to interact with both the backend and frontend.

Here are some of Angular’s ​​best features:

1. Model-View-ViewModel (MVVM)

To build client-side web applications, Angular uses raw MVC The fundamental principles behind software design patterns come together. However, Angular does not implement MVC in the traditional sense, but implements MVVM, the Model-View-ViewModel pattern.

2. Dependency Injection

Angular comes with built-in dependency injection subsystem functionality, which makes applications easy to develop and test. Dependency injection allows developers to obtain dependencies by requesting them instead of searching for them. This is very helpful for developers.

3. Testing

In Angular, controllers and directives can be unit tested separately. Angular allows developers to have end-to-end and unit test runner setups, which means testing from the user perspective can also be done.

4. Cross-browser compatibility

An interesting feature of Angular is that applications written in the framework run well in multiple browsers. Angular automatically handles the code required by each browser.

5. Directives

Angular directives (DOM templates used to render directives) can be used to create custom HTML markup. These are tags on DOM elements because developers can extend the directive vocabulary and make their own directives, or convert them into reusable components.

6. Deep Linking

Since Angular is mainly used for making single-page applications, you must take advantage of the Deep Linking feature to load child templates on the same page. The purpose of Deep Linking is to look at the location URL and arrange for it to map to the current state of the page.

Deep Linking feature sets the URL by looking at the page status and taking the user to specific content instead of traversing the application from the home page. Deep Linking allows all major search engines to easily search web applications.

Vue.js vs. Angular--Which one is best?

Which framework is best - Angular or Vue? Let’s delve into it through the following points:

Learning Curve

In terms of learning curve, Vue.js is relatively simple to learn and understand, while Angular takes time to get used to. Developers feel that both frameworks are great for projects, but most of them prefer to use Vue because Vue is simpler and scales well when Vuex is added to the project.

Although some of the syntax of Vue and Angular are similar, such as API and design (this is because Vue is actually inspired by the early development stages of Angular), Vue has always been committed to some aspects that are unique to Angular. It’s very difficult to improve yourself. Developers can build an ad hoc application with Vue.js in a few hours, but this is not possible with Angular.

Flexibility

Angular is self-contained, which means your application should be structured in a certain way. Vue is even broader. Vue provides a modular and flexible solution for creating applications.

Many times, Vue is considered a library rather than a framework. By default, Vue does not include routers, HTTP request services, etc. Developers must install the required "plug-ins". Vue is very flexible and compatible with most libraries that developers want to use.

However, there are developers who prefer Angular because it provides support for the overall structure of their applications. This helps save coding time.

Document Object Model (DOM)

Vue can precompile templates into pure JavaScript with minimal component re-rendering. This virtual DOM allows for a lot of optimizations, which is the main difference between Vue and Angular. Vue allows for a simpler programming model, while Angular manipulates the DOM in a cross-browser compatible way.

Speed/Performance

While both Angular and Vue offer high performance, it can be said that Vue is slightly ahead in speed/performance due to the lighter weight of Vue's virtual DOM implementation.

A simpler programming model enables Vue to provide better performance. Vue can be used without a build system because developers can include it in HTML files. This makes Vue easier to use, which improves performance.

The reason Angular can be slow is that it uses dirty data checking, which means Angularmonitors are constantly looking to see if variables have changed.

Two-way data binding

Both frameworks support two-way data binding, but compared to Vue.js, Angular’s ​​two-way binding is more complex. Two-way data binding in Vue is very simple, and in Angular, data binding is even simpler.

When to choose Vue.js?

If you want to create web applications in the simplest way, then you should choose Vue. If your Javascript foundation is not too strong, or you have strict development deadlines, Vue would be a good choice.

If your front-end is Laravel, then please choose Vue. Developers in the Laravel community consider Vue to be their favorite framework. Vue reduces total processing time by 50% and frees up space on the server.

If you are developing a small-scale application or do not like to be constrained during development, please choose Vue.

If you are familiar with ES5 Javascript and HTML, then please use Vue to complete your project.

If you want the simplicity of compiling templates in the browser and using them, using the standalone version of Vue will be fine.

If you plan to build a performance-critical SPA or need functionally scoped CSS, Vue's single-file components are perfect.

When to choose Angular?

If you need to build large and complex applications, then you should choose Angular because Angular provides a complete and comprehensive solution for client application development.

Angular is a good choice for developers who want to work with both client-side and server-side patterns. The main reason why developers love Angular is that it enables them to focus on any kind of design, whether it's jQuery calls or DOM configuration interference.

Angular is also suitable for developers creating web applications with multiple components and complex requirements. When you choose Angular, local developers will find it easier to understand the application functionality and coding structure.

If you want to select existing components in a new project, you can also choose Angular because you can just copy and paste the code.

Angular can use the two-way data binding feature to manage synchronization between the DOM and the model. This makes Angular a powerful tool for web application development.

Developers who want to make lighter and faster web applications can take advantage of the MVC structure and independent logic and data components in Angular, which helps speed up the development process.

Code Comparison

It is interesting to analyze the code of Vue and Angular. Code containing markup, styles, and behaviors helps developers build efficient and reusable interfaces. In Angular, entities like controllers and directives are contained in modules, while Vue’s modules contain component logic.

Vue component

  Vue.extend({ 
    data: function(){ return {...} }, 
    created: function() {...}, 
    ready: function() {...}, 
    components: {...}, 
    methods: {...}, 
    watch: {...} 
    //(other props excluded) 
});

Angular module

angular.module(‘myModule’, […]);

Directive in Angular is more powerful.

Vue Directive

Vue.directive('my-directive', {
       bind: function () {...}, 
      update: function (newValue, oldValue) {...}, 
      unbind: function () {...}
  });

Angular Directive

myModule.directive('directiveName', function (injectables) { 
      return { 
            restrict: 'A', 
            template: &#39;<p></p>&#39;, 
            controller: function() { ... },
             compile: function() {...},
             link: function() { ... } 
            //(other props excluded) };
            });

Since Vue.js is inspired by Angular, it also borrows Angular templates grammar. Hence the syntax for loops, interpolation and conditionals are very similar in both frameworks.

The code snippet is given below:

Vue interpolation

{{myVariable}}

Corner interpolation

{{myVariable}}

Vue Loop

{{myProperty}}

Angular Loop

<li ng-repeat="item in items" class="item-{{$index}}"> 
{{item.myProperty}}
</li>

Vue Condition

<p v-if="myVar"></p> 
<p v-show="myVar"></p

Angular Condition

<p ng-if="myVar"></p>
<p ng-show="myVar"></p>

Vue.js coding makes page rendering very simple. In fact, Vue.js is more like a library than a framework because it does not provide all the features of Angular. Developers will have to rely on third-party code for Vue.js, while Angular provides features such as HTTP request services or routers.

Angular and Vue.js version release

The latest stable version of Vue.js v2.3.4 was released on June 8, 2017. Before this version, there were 13 more versions.

Angular 4 was released in March 2017. Earlier versions were Angular 1 and 2, not Angular 3. Version 5 of Angular was released in November 2017. Version 6 is expected to be released in March 2018, and version 7 is expected to be released in September/October 2018.
