Vue.js is an open source JavaScript framework that helps developers to build beautiful WEB interfaces. When used in conjunction with other network Tools, Vue.js's excellent functionality will be greatly enhanced. Today, many developers have begun to use Vue.js to replace Angular and React.js.

So for Angular and react.js, how do developers choose?

We will introduce and contrast these two frameworks in depth.

Vue.js was developed by former Google employee Evan you and was released in 2014 and now has more than 57,000 GitHub star. Many developers strongly recommend Vue because it is easy to learn. If you have deep HTML, CSS, and JavaScript basics, then learning Vue.js takes only a few hours.

The most attractive thing about Vue for developers is that it's novel, lightweight, and rarely even complex. Vue is not only very flexible but also very powerful, but also provides two-way data binding capabilities, just like the virtual DOM functionality of Angular and React.

Vue can help developers build applications in whatever way they want, something Angular can't do.

Vue.js-a diverse JavaScript framework

As a cross-platform, highly progressive framework, Vue has become a top choice for developers who need to create single-page applications. In a typical MVC architecture for developing WEB applications, Vue acts as a view, which means that it allows developers to see the display of the data. In addition to the basic features mentioned above, Vue has many other outstanding features.

Let's take a look at these:

1. Easy to use

If you've been using other frameworks, you can easily use Vue, because the core library of Vue focuses on the View layer, and you can easily integrate it with third-party libraries and work with existing projects.

2. Lightweight

Vue is lightweight because Vue focuses primarily on ViewModel or bidirectional data binding. Vue also has very basic documentation. Vue is used as a View layer, meaning that developers can use it as a highlight feature on the page, providing a better choice than a full spa,vue.

3. Learning curve is very low

Developers familiar with HTML will find that Vue has a low learning curve and can quickly learn and understand Vue for less experienced developers and beginners.

4. Bidirectional binding

Vue provides V-model directives (data for updating user input events), making it easy to implement two-way binding on form input and structural elements. It can choose the correct way to update the elements associated with the input type.

5. Virtual DOM

Because Vue is a lightweight virtual DOM implementation based on Snabbdom, Vue has a slightly improved performance. This is one of the main new features of virtual DOM, and developers can update them directly. When you need to make changes in the actual DOM, you only have to perform one such update function at a time.

6. HTML template-based syntax

Vue allows developers to bind the rendered DOM directly 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 fully functional framework that supports the Model-view-controller programming structure and is ideal for building dynamic, single-page Web applications.

Google developed the Angular and supported it in 2009, and Angular contains a JavaScript code base based on both standard and HTML. The original purpose of the Angular design was as a tool to enable designers to interact with the backend and front end.

The following are some of the best features of Angular:

1. Model-view-viewmodel (MVVM)

To build a client-side Web application, Angular combines the rationale behind the original MVC software design pattern. However, Angular does not implement MVC in the traditional sense, but instead implements the MVVM-Model-view-viewmodel pattern.

2. Dependency Injection

The Angular comes with built-in dependency injection subsystem functionality, which makes the application easy to develop and test. Dependency Injection allows the developer to obtain a dependency through a request, rather than searching for a dependency relationship. This is very helpful for developers.

3. Testing

In Angular, the controller and the instruction can be individually unit tested. Angular allows developers to set up end-to-end and unit test runner, which means that they can also be tested from the user's perspective.

4. Cross-Browser compatible

An interesting feature of Angular is that applications written in the framework can work well in multiple browsers. Angular can automatically process the code required for each browser.

5. Directives

Angular directives (DOM templates for rendering instructions) can be used to create custom HTML tags. These are tags on DOM elements, because developers can extend the instruction glossary and make their own instructions, or convert them into reusable components.

6. Deep linking

Because Angular is primarily used to make single-page applications, the deep linking feature must be leveraged to load child templates on the same page. The purpose of deep linking is to view the location URL and schedule it to map to the current state of the page.

The deep linking feature sets the URL by viewing the page state 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 for Web applications.

Vue.js and angular--which one is best?

Which frame is the best-Angular or Vue? Below we will delve into the following points:

Learning curve

In terms of learning curve, vue.js learning and understanding is relatively simple, while Angular takes time to get used to. Developers think both frameworks are great for the project, but most of the developers prefer to use Vue because the Vue is simpler and extensible when Vuex is added to the project.

Although Vue and Angular are similar in syntax, such as APIs and design (because Vue is actually inspired by the early stages of Angular development), Vue has been working to improve itself in some difficult areas for Angular. Developers can build a special application with vue.js within a few hours, but this is not possible for Angular.

Flexibility

Angular is independent, which means that your application should be structured in a certain way. Vue is more broad, and Vue provides a modular, 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, and so on. The developer must install the required "plugins". Vue is very flexible and can be compatible with the libraries most developers want to use.

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

Document Object Model (DOM)

Vue is re-rendered with the smallest number of components, and the template can be precompiled to pure JavaScript. This virtual DOM allows for a lot of optimization, which is the main difference between Vue and Angular. Vue allows for a simpler programming model, while Angular operates the DOM in a cross-browser-compatible manner.

Speed/performance

While both Angular and Vue provide high performance, the Vue's virtual DOM is lightweight, so it can be said that the speed/performance is slightly ahead.

A simpler programming model allows Vue to provide better performance. Vue can be used without building a system, because developers can include it in an HTML file. This makes Vue easy to use, which improves performance.

The reason Angular can be slow is that it uses dirty data checking, which means that angularmonitors will continue to see if the variable is changing.

Bidirectional data binding

Both frameworks support bidirectional data binding, but Angular's bidirectional binding is more complex than vue.js. Bidirectional data binding in Vue is simple, and in Angular, data binding is simpler.

When to choose Vue.js?

If you want to make a WEB application in the simplest way, you should choose Vue. Vue will be a good choice if your Javascript base is not too strong, or if you have a tight deadline for development.

If your front-end is Laravel, then please choose Vue. The developers of the Laravel community think Vue is their favorite frame. Vue reduces total processing time by 50% and frees up space on the server.

If you are developing a small-scale application or are not interested in being constrained during development, select Vue.

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

If you want to compile the template in a browser and use its simplicity, it would be nice to use the standalone version of Vue.

If you are planning to build a performance-critical spa or a Css,vue single-file component that requires a functional range, it will be perfect.

When to choose Angular?

If you need to build large, complex applications, 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 handle client and server-side patterns. The main reason developers like Angular is that Angular enables them to focus on any type of design, whether it's a jQuery call or a DOM configuration disturbance.

Angular also applies to developers who create 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 an existing component in a new project, you can also choose Angular, because you only need to copy and paste the code.

Angular can use bidirectional data binding capabilities 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, faster Web applications can take advantage of the MVC architecture and independent logic and data components in Angular, which helps speed up the development process.

Code comparison

It's interesting to analyze the code for Vue and Angular. Code that contains tags, styles, and behaviors can help developers build efficient and reusable interfaces. In Angular, entities such as controllers and directives are included in modules, while Vue's modules contain component logic.

Vue Components

  Vue.extend ({     data:function () {return {...}},     created:function () {...},     ready:function () {...},     Components: {...},     methods: {...},     watch: {...}     (Other props excluded)});

Angular Module

Angular.module (' MyModule ', [...]);

The Directive in Angular is more powerful.

Vue instruction

Vue.directive (' my-directive ', {       bind:function () {...},       update:function (newvalue, OldValue) {...},       Unbind:function () {...}  });

Angular instruction

Mymodule.directive (' Directivename ', function (injectables) {       return {             restrict: ' A ',             Template: ' <div ></div> ',             controller:function () {...},             compile:function () {...},             link:function () {...}             (Other props excluded)};            });

Because Vue.js is inspired by Angular, Angular's template syntax is also borrowed. So loops, the interpolation and condition syntax for both frames are very similar.

Here's the code snippet:

Vue interpolated Values

Angular interpolation

{{myvariable}}

Vue Loops

<li v-repeat= "Items" class= "item-{{$index}" >{{myProperty}}</li>

Angular Loops

<li ng-repeat= "Item in Items" class= "item-{{$index}}" > {{item.myproperty}}</li>

Vue conditions

<div v-if= "MyVar" ></div> <div v-show= "MyVar" ></div

Angle condition

<div ng-if= "MyVar" ></div><div ng-show= "MyVar" ></div>

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

Release of Angular and Vue.js

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

Angular 4 was released in March 2017. Earlier versions were Angular 1 and 2, without Angular 3. The 5th edition of Angular was released in November 2017. The 6th edition is expected to be released in March 2018, and the 7th edition is expected to be released in September 2018/October.

Conclusion

Vue.js is a lightweight development framework that is ideal for developing small, flexible Web applications, while Angular is a great choice for building complete and complex applications despite the steep learning curve.
